Why does anyone use jQuery for AJAX calls? In fact, for a lot of things? OK, there's no point in reinventing the wheel, and people have built some nice things with it, notably photo sliders/ carousels etc, but for so many things - and AJAX is a case in point - good ol' vanilla JavaScript is so much easier! A number of times now I've looked at using jQuery for AJAX, and given up in frustration. No more.
Sledgehammers and nuts come to mind.

Really?

JavaScript

if (window.XMLHttpRequest) {
    httpRequest = new XMLHttpRequest();
} else if (window.ActiveXObject) {
    httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}

httpRequest.onreadystatechange = function() {
  if (httpRequest.readyState == 4 && httpRequest.status == 200) {
    var result = httpRequest.responseText;
    // Do something with the result
  }
};

httpRequest.open("GET", theUrl, true);
httpRequest.send();

vs:

JavaScript

$.ajax({
    url: theUrl
    // Other options...
}).done(function(result){
    // Do something with the result...
});

Also, the jQuery version[^] has a lot of built-in functionality which you would have to reimplement if you wanted to use it in the plain Javascript version.

One of the nice things about jQuery is that it hides per-browser implementation from the client; you don't need to know the differences between how IE\Chrome\FireFox implements ajax, or even if there are differences in how individual versions work. People also keep jQuery up-to-date again so you don't have to. Add to that the syntax is much easier as Richard has already pointed out, and it has nice features you'd have to code yourself such as making "get" calls non-cached etc.

If the only reason you're using jQuery is for ajax then you might have a point, but if I'm honest even if ajax was all I was doing I'd probably still use jQuery as it is lightweight and you'll probably end up using the other features anyway.

Well, I don't find the syntax (or documentation) clear at all.

Maybe I should turn this into a question: how would you, for example, "jQueryify" this?

JavaScript

if (window.XMLHttpRequest) {
    rQM = new XMLHttpRequest();
} else if (window.ActiveXObject) {
    rQM = new ActiveXObject("Microsoft.XMLHTTP");
}

function getPage(p, tImg, iImg, t, s, h) {
   var r = new Date().getTime();
   var url = 'pagebox.ashx?p=' + p.toString() + '&r=' + r.toString();
   rQM.open("GET", url, true);
   rQM.onreadystatechange = function () {
      UpdateScreen(p, tImg, iImg, t, s, h);
   }
   rQM.send(null);
}

function UpdateScreen(p, tImg, iImg, t, s, h) {
   if (rQM.readyState == 4) {
      var response = rQM.responseText;
      if (response != '') {
         var params = response.split("|");
         document.getElementById(tImg).value = 'userfiles/' + params[0];
         document.getElementById(iImg).src = 'userfiles/' + params[0];
         document.getElementById(t).value = params[1];
         document.getElementById(h).value = params[2];
         tinyMCE.get(s).setContent(params[3]);
      }
   }
}

(tinyMCE references the tinyMCE HTML editor[^])

To me, that is pretty easy to grok - I've tried over and over to work out how to do it in jQuery and, as I say given up each time in despair...

(And, yes, I know it's a little ugly in the return - I should probably return the data as XML or JSON, but it works well enough for my purposes.)

Something like this should work:

JavaScript

function getPage(p, tImg, iImg, t, s, h) {
    $.get({
        url: 'pagebox.ashx?p=' + p.toString(),
        cache: false
    }).done(function(response) {
        updateScreen(p, tImg, iImg, t, s, h, response);
    });
}

function UpdateScreen(p, tImg, iImg, t, s, h, response) {
    if (response != '') {
        var params = response.split("|");
        document.getElementById(tImg).value = 'userfiles/' + params[0];
        document.getElementById(iImg).src = 'userfiles/' + params[0];
        document.getElementById(t).value = params[1];
        document.getElementById(h).value = params[2];
        tinyMCE.get(s).setContent(params[3]);
    }
}

How to hide the URL textbox using javascript

As simple as that, huh...?

sigh... Blush | :O

I can't figure out how to do the following with javascript:
- user enters a url for an html page e.g. Start.html
- on that html page there is link the user needs to click
When the user clicks that link I want to:
- reload the current browser window (NOT open new browser window or a new tab) with the url of some aspx page
- remove any browser related menus/buttons and the URL textbox.

Here is what I have in the html body:
Login

Here is the associated javascript:
function openClient() {
clientWindow = window.open('Login.aspx?p=1','_self','directories=no,location=no,menubar=no,scrollbars=yes,status=no,toolbar=no,resizable=yes');
}

The part about loading the asp page in the same browser window works fine. The part that's not working is removing all the browser related buttons and the URL textbox. I can still see the URL textbox.

Can anyone please help?
thanks,

You can't. If it was possible for script to hide the URL, menus and toolbars, every malicious site on the net would do it.

Even if you open the page in a new window, most browsers will still show the URL.

I have an old javascript that works in both IE and Firefox but it's for a new browser window, not a current one. So, there is no way to do it for the current browser window? What about by using css to hide it? Any way to disable it?

Nathan Minier25-Mar-16 1:08

Not without a browser extension installed on the system that you want to do this on.

It's a terrible idea, by the way.

IE has a setting to show the address bar even with the code you have. So, the real answer is no, there is no way to ensure it. It will depend on which browser the user is using and what their settings are.

However, what you can do is create a div on your page that has all the same controls and then can easily display that using jquery ui's dialog feature. See Dialog | jQuery UI[^].

There are only 10 types of people in the world, those who understand binary and those who don't.

Yes and No.

You could do this in some browsers however what you are trying to do is out of your control. You have no control over what extensions , versions and plugins of the browsers the client computer has got.

You need to review your requirement and take an alternative route for what you are trying to achieve.

,{id:12,data:["12","L","20"]}

I was wondering if I can get a kick start suggestion to write our own group by function to group on any column. Like in above example, we can use the second column to group by.

The only restriction I have is that I can't use jquery and have to use java script only.

AngularJS view ng-grid not refreshing after ngDialog close.

23-Mar-16 1:56

You can overload the standard Array.sort() in the same manner as a standard comparative operation.

The problem that you have is that your rows are not properly formatted for JSON (it looks like your data value should be an object, not an array) and you're mixing strings and integers. If you ONLY want to group by 1 field that's easy, if you want flexibility then you'll have a more complicated operation on your hands. One sort function will not be suitable for your needs, since string comparisons in Javascript will give you wonky results when used on stringified numbers, and using numerical comparisons on strings will also give bad data.

Array.prototype.sort() - JavaScript | MDN[^] has a bunch of suggestions for how to handle sorting of various data types and uses vanilla Javascript.

I have an AngularJS view that contains a ng-grid row cellTemplate icon button. The problem only happens in IE and not in Google Chrome. When the user selects the icon button a ngDialog is opened and on the dialog close event the dialog closes then the selected icon button increases in size in the cell and all of the text in that row shifts up and to the left. I have tested this in Google Chrome and the problem does not occur. What I am seeing is that the entire browser seems to do a shift to the right then back when I do close the dialog. It was recommended to me that on dialog close I close the dialog then redirect to a dummy view which redirects back to reload the view with ng-grid. I tried that but am unable to get working.

The dialog definition, and the cellTemplate markup the contains the icon button that calls the open dialog event is shown below along with the dialog open and close event

HTML

<script type="text/ng-template" id="ApproverCommentsDialog">
<div class="ngdialog-message">
<h3>Approver Comments</h3>
<p>
({ApproverComment}}
</p>
</div>
<div id="gridDiv" class="ngdialog-buttons">
<button type="button" ng-click="OKClicked()" class="ngdialog-button ngdialog-button-primary">OK</button>
</div>
</script>


var = cellTemplateIconWithTooltip = '<div class="ngCellText" ng-class="col.colIndex() - 1"><a title="Show" ng-click="displayComments(row.entity)"><img src="../../../../Content/images/managerequests.png" style="float: right; padding:5px; border:3px" height="20px" width="20px" /></a></div>';

        $scope.displayComments = function (row) {
            $scope.ApproverComment = row.ApproverComments;
            ngDialog.open({
                template: 'ApproverCommentsDialog',
                className: 'ngdialog-theme-default',
                data: row.ApproverComments,
                scope: $scope
            });
        };

        $scope.OKClicked = function () {
            ngDialog.close();
        }; 

Any help would be great.
