Re: How to display a pop up without click and without login

Don't.

Unsolicited popups are vile, evil design patterns promoted by spammers and people trying to milk the cash cow of the Internet by opening up a kiddie Shopify store, etc. They have very little place in a professional design and instantly devalues the site's perception.

If you're trying to distract the user from their action by showing an ad, newsletter signup, etc. consider at the very least a partial overlay that stands out but doesn't completely obstruct the user.

How to show or hide a div with only class without ID

hello I have a problem I have a purchase order with 500 items, in this example I only put 3 items
When I add an item to the cart I would like to be able to display the panel div but just for the item that was put in the cart with the ajouter au panier button

But when I click on retirer du panier I want the button to disappear

HTML

<pre>       <a data-nom="2001" class="btn btn-primary ajouter-panier b-items__item__add-to-cart" onclick="myFunction();">
                       ajouter au panier
                     </a><br>

                     <div class="panel" style="display:none">
                       <a data-qte2="0" class=" ajouter-panier ">
                         retirer panier
                       </a><br>
                     </div>
                     <a data-nom="2002" class="btn btn-primary ajouter-panier b-items__item__add-to-cart" onclick="myFunction();">
                       ajouter au panier
                    </a><br>

                     <div class="panel" style="display:none">
                       <a data-qte2="0" class=" ajouter-panier ">
                         retirer panier
                       </a><br>
                     </div>
                     <a data-nom="2003" class="btn btn-primary ajouter-panier b-items__item__add-to-cart" onclick="myFunction();">
                       ajouter au panier
                     </a><br>

                     <div class="panel" style="display:none">
                       <a data-qte2="0" class=" ajouter-panier ">
                         retirer panier
                       </a>

<pre lang="Javascript">function myFunction() {
 var a = document.querySelectorAll(".panel[style*='display:none']");
 console.log ("display",a)
a[0].style.display ='block'; 
}

function myFunction2() {

With the specified markup, the only way to identify the correct panel is to loop through the sibling elements until you find it:

HTML

<a data-nom="2001" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
    ajouter au panier
</a><br>

<div class="panel" style="display:none">
    <a data-qte2="0" class=" ajouter-panier ">
        retirer panier
    </a><br>
</div>
<a data-nom="2002" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
    ajouter au panier
</a><br>

<div class="panel" style="display:none">
    <a data-qte2="0" class=" ajouter-panier ">
        retirer panier
    </a><br>
</div>
<a data-nom="2003" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
    ajouter au panier
</a><br>

<div class="panel" style="display:none">
    <a data-qte2="0" class=" ajouter-panier ">
        retirer panier
    </a>
</div>

JavaScript

document.addEventListener("click", e => {
	let el = e.target;
	if (el.tagName !== "A") { el = el.closest("a"); }
	if (!el || !el.classList.contains("b-items__item__add-to-cart")) { return; }
	
	e.preventDefault();
	
	let panel = el.nextElementSibling;
	while (panel && panel.tagName !== "DIV"){
		panel = panel.nextElementSibling;
	}
	
	if (panel) {
		panel.style.display = "block";
	}
});

Demo[^]

If you can change the markup structure so that each link and panel have a wrapper element, then it becomes slightly easier:

HTML

<div class="item-card">
    <a data-nom="2001" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
        ajouter au panier
    </a><br>

    <div class="panel" style="display:none">
        <a data-qte2="0" class=" ajouter-panier ">
            retirer panier
        </a><br>
    </div>
</div>
<div class="item-card">
    <a data-nom="2002" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
        ajouter au panier
    </a><br>

    <div class="panel" style="display:none">
        <a data-qte2="0" class=" ajouter-panier ">
            retirer panier
        </a><br>
    </div>
</div>
<div class="item-card">
    <a data-nom="2003" class="btn btn-primary ajouter-panier b-items__item__add-to-cart">
        ajouter au panier
    </a><br>

    <div class="panel" style="display:none">
        <a data-qte2="0" class=" ajouter-panier ">
            retirer panier
        </a>
    </div>
</div>

JavaScript

document.addEventListener("click", e => {
	let el = e.target;
	if (el.tagName !== "A") { el = el.closest("a"); }
	if (!el || !el.classList.contains("b-items__item__add-to-cart")) { return; }
	
	const card = el.closest(".item-card");
	if (!card) { return; }
	
	const panel = card.querySelector(".panel");
	if (!panel) { return; }
	
	e.preventDefault();
	panel.style.display = "block";
});

Demo[^]

In either case, it's best to avoid the onclick attribute, and wire up the event handlers in code. In this case, I've used event delegation[^], which is generally more efficient than adding handlers to multiple elements, and also allows the code to handle events on elements which are added to the DOM at some later time.

Excuse me for disturbing you.
I just tried the code on my site, but I have a little compatibility problem with what already exists on my site.
maybe you could help me

When I add an item to my cart
I have an animation that drives the item into its shopping cart.

for your code to work I have to deactivate part of my code from line 29 to 34, but in this case I no longer have my animation

Could you help me please

The code sample has a few script errors, particularly around a missing .b-cart element and a missing external reference.

Beyond that, since you're using jQuery, you don't need the code from my previous answers. Within the "add-to-cart" click event handler, you just need to add:

JavaScript

var panel = item.find('.panel');
panel.show();

To hide the panel when its nested link is clicked, add:

JavaScript

$(document).on('click', '.panel a.ajouter-panier', function(evt){
	this.closest('.panel').style.display = 'none';
});

Not until you learn how to ask a proper question.

Dumping 500+ lines of unformatted, unexplained code and appending a vague description of your requirement is not a good question.

Start by explaining precisely what you are trying to do, what you have tried, and where you are stuck. When including code, include only the relevant parts of the code, and ensure it is formatted properly by selecting it and pressing the code button on the toolbar, or surrounding it with <pre>...</pre> tags.

How do I make an Element slide-in, after user selects choice from drop-down, then it slides out.

Garry 202316-Feb-23 12:07

Garry 2023

I need an element on my page to slide-in automatically 3 seconds after page is opened, and then slide-out after user chooses their preferred choice from the dropdown menu (which is the Element). I want the slide-in/slide-out effect to be from the right-hand side of the page. 

The dropdown menu particularly is the 'Google Translate Element', which I have styled to my desired appearance, and I want this to slide in 4 seconds upon page lunch and after user chooses desired language, it slides out.

Below is the code for the styled Element

 /*google translate Dropdown */

Copying from billing address to mailing address if they are the same not working correctly

I have a form that asks users to provide their billing and shipping addresses.

If the billing address is same as the mailing address, click a checkbox to copy the billing address information to mailing address boxes.

So far, address, city and zip are getting copied from billing to mailing addresses but the State address is not getting copy.

The billing State has a hardcoded value of WI for Wisconsin. That NEVER changes, hence it is hardcoded.

The mailing address for State has a DropDownList of states, I am pretty sure that has to do with why the billing address for State is not getting cover over to mailing address for State.

Can you guys please see what I am doing wrong?

Here is what I am working with.

    <script type="text/javascript">
        $('#SameAsMailing').click(function () {
         if ($('input[name="SameAsMailing"]').is(':checked')) {
         $('#mailStreetAddress').val($('#instAddress').val());
         $('#mailCity').val($('#instAddressCity').val());
         var thestate = $('#instAddressState option:selected').val();
         if (thestate != "") {
                     $('#mailState option[value="' + thestate + '"]').prop('selected', true);
              }
         $('#mailZip').val($('#instAddressZip').val());
         }
       else
        {
        //Clear on uncheck
        $('#mailStreetAddress').val("");
        $('#mailCity').val("");
        $('#mailState option:eq(0)').prop('selected', true);
        $('#mailZip').val("");
       }
     });
   </script>

Thank you for your response sir but it did not work.

In other words, the value of WI did not get copied to the mailState DropDownList.

I tried hardcoding the State value since that will always be the same like this:

var thestate = 'WI';
if (thestate !== "") {
    $('#mailState').val(thestate);
}

It appears to change something on the mailState dropdownlist but did not display that WI value in the dropdown.

Instead, it showed blank value as the selected value on the mailState dropdownlist box.

Ajax didn't work for cloning rows, But works for first row only

Hi all,
I’ve two issues

The first one:
as you can see in the second image (when cloning select input with select2 plugin, the cloned input appears with (the first disabled item appended next to the main input in every row)).
[Original row image]
[My issue image]

the second issue:
I’ve ajax code to append “unit menu” based on “product menu” selection
when I create a new row, and select an item from “product menu” I expected that the “unit menu” of the same row must affect and append the “unit list” belongs to the selection of the "product menu" in the same row.
But the behavior according to the next code is very different (after cloning the main row, when I select a product the appended unit list (appears in all unit menu in every row) and after I used ("this" or "the new created class") I get an empty "unit menu" in the new rows (i.e when select a product no changes takes place in the "unit menu")
Only the first row works (select a product append a menu to "unit input menu")

Finally I fix my issue as usual. I want to share my solution of this issue.

JavaScript

$(document).on('change', '.product', function(e){
            var product_id = $(this).val();
            let $el = $(this).closest('.purchase-row');

                data: {
                    'pro-product': product_id,
                },
                success: function (data) { 
                    if (purchaseCount == 0) {
                        console.log('purchase count equal to ZERO: ');
                        console.log(
                            'FROM SUCCESS: ', data['unit'],
                        );
                        var values_3 = data['unit'];               
                        if (values_3.length > 0) {
                        
                            for (var i = 0; i < values_3.length; i++) {
                                $el.find('.unit').append('<option>' + values_3[i] + '</option>');
                            }
                        }
                    } else {
                        let unit = $el.find('.newUnit'); // here I can access the "unit input" of the same row of the "product input"
                        var values_3 = data['unit'];
                        unit.text('');
                        console.log('COUNT IS NOT EQUAL TO ZERO:', values_3);
                        if (values_3.length > 0) {
                            for (var i = 0; i < values_3.length; i++) {
                                unit.append('<option>' + values_3[i] + '</option>');
                            }

                },
            });
            e.preventDefault();
        });

Or in an enhanced code snippet as follow

JavaScript

$(document).on("change", ".product", function (e) {
    var product_id = $(this).val();
    let $el = $(this).closest(".purchase-row");
    console.log("SUCCESS-CHANGE-PRODUCT: ", product_id);
    $.ajax({
      type: "POST",
      url: '{% url "purchases:get_product_unit" %}',
      data: {
        "pro-product": product_id
      },
      success: function (data) {
        const values_3 = data.unit;
        const unitClass = purchaseCount == 0 ? ".unit" : ".newUnit";
        const unit = $el.find(unitClass);
        unit.text(''); 
        if (values_3.length) {
          for (const value of values_3) {
            unit.append(`<option>${value}</option>`);
          }
        }
      },
      error: function () {
        console.log("ERROR with ajax request in Adding Purchase !!!");
      }
    });
    e.preventDefault();
  });

Hi everyone,

I wrote this great script to help my team set up the weekly task distribution board, I wrote it using java script, html, and css, they've been doing it for a very long time in pencil on paper. but now i am in the final stage, i would like to convert my table to pdf, and this is where i found it difficult, i did several tests : like convert csv to pdf, it doesn't always give a good table, as it is under html. I would like to add a column at the end of the table for remarks but I think I will try with it later. now i'm just focus on pdf export. to be able to print our table every week and hang it, instead of pencil and a paper.
