adding a item to listbox by javascript [modified]

Hi,

I have a form, and in this form, there's a button and a listbox.

The question is how to add a item to the listbox using javascript when the user clicks on the button.

This is my thinking but it doesn't work.

<script language="javascript">
var lb = document.getElementById('mylist');
lb.options.....(what will be here?) :doh: 
</script>

<form>
<select name="mylist" id="mylist">
</select>
</form>

Thanks in advance

Try the following:

<script language="javascript">
var lb = document.getElementById('mylist');
var option = document.createElement("option");
lb.options.add(option);
option.text = "This is option one";
option.value = "1";
</script>

Firefox and onblur event

ycorre31-Mar-09 14:55

31-Mar-09 14:55

Hello,

I have an ASP.Net application where all my TextBox components contain the "onblur" and "onfocus" events.

The principle:
- I'd like to allow the text selection in the control (when focusing)
- I'd like to disable the text selection of my page when outside the control (on onblur)

So, I have this code on the onfocus event :

Code:

function SetBodyDragOn(o)
{
  document.body.onselectstart = new Function("return true;");
  document.body.ondragstart = new Function("return true;");
  document.body.onselect = new Function("return true;");
 
  // Set an edit design class on the textbox control
  if (o)
    o.className = "InputEditingOn";
}

And this one on the onblur event :

Code:

function SetBodyDragOff(event, o)
{
  if (typeof event.preventDefault != 'undefined') event.preventDefault();
  document.body.onselectstart = new Function(" {event.returnValue=false; try { event.stopPropagation(); event.preventDefault() } catch (ex) {alert(ex.message)} return false; } ");
  document.body.ondragstart = new Function(" {event.returnValue=false; try { event.stopPropagation(); event.preventDefault() } catch (ex) {alert(ex.message)} return false; } ");
  document.body.onselect = new Function(" {event.returnValue=false; try { event.stopPropagation(); event.preventDefault() } catch (ex) {alert(ex.message)} return false; } ");
 
  // Set a standard design class on the textbox control
  if (o)
    o.className = "InputEditingOff";
}

With all the browsers (even Firefox), it works fine during one moment.
After a certain time of using, on Firefox, the onblur is not fired.
The cursor stays in the control.

Why this behavior?
Why it works a certain time and not after (memory problem?)
To soluce the problem, I have to reboot my Firefox.

Thanks in advance,
Yannis.

WSS and Ajax

I have a custom application page with code-behind in WSS. The page has two dropdownlists, one with AutoPostback=true so it will filter the contents of the second. They are wrapped in an Ajax UpdatePanel.

When I select from the first dropdown I get the below Javascript error. Doing a Google search finds 5 hits (and two are from us). Has anyone come across this?

System.Runtime.CompilerServices.StrongBox`1..ctor(System.__Canon)

This is definitely a WSS issue since the code has been tested in an ASP.NET page and it works as expected.

I've been trying to narrow the problem down. I'm trying to filter a list of states based on the selected country

int countryID = Convert.ToInt32(CountryList.SelectedItem.Value);
// This doesn't work
var states = context.State.Where(c => c.Country.ID == countryID).ToList();

// This does
var states = context.State.Where(c => c.Country.ID == 2).ToList();

StateList.DataSource = states;
StateList.DataBind();

No matter how I try filter the EF object, Select, Where, etc., if it uses a variable, it fails. I've even tried creating a DataTable and populating it from states, but that doesn't work either.

Very perplexing.

Changing a form's target through javascript

Hi guys,

I am currently writing the payment part of a webshop. There are three ways of payment, and the customer szelects one of these three by means of a selection in the form. The actual submit button start a javascript function that checks the payment method and sets the form's target to a intermediate page for each of the three payment methods. The code I use is very simple:

if (document.orderform.method[0].checked == true)
{
document.orderform.target = '_self';
document.orderform.submit();
}
else if (document.orderform.method[1].checked == true)
{
document.orderform.target = '_self';
document.orderform.action = 'ideal.php';
document.orderform.submit();
}
else if (document.orderform.method[2].checked == true)
{
document.orderform.target = '_blank';
document.orderform.action = 'paypal.php';
document.orderform.submit();
}
else
alert ("please select a payment method");

This works fine in firefox, however IE7 says "object doesn't support this property or method" This occurs at "...action='ideal.php';" When I give the action a value (document.orderform.action.value='ideal.php') IE does not complain, but does not change the form's action either (also firefox does not change the action anymore)

Does anyone have a suggestion on how to change the form's action in all browsers?

Any suggestions are greatly appreciated.

Thanks in advance,
William

run this through jslint,
tips:
always use triple = for comparison (===)
opening brackets must come on the same line as the conditional statement opening them, Javascript does strange things in certain situations if it's on the next line.

AoA

Thanks in advance for help. Please help me if any one have some info about it.

I have made a solution with three projects a web services project , a client windows application project and a class library project.

I made a class in class library. this class library is added as reference in the client and web services project.

Now from client application, when i call some web methods of the web service they work fine.

I have a web method with an object type attribute. that method just cast it to string using ToString() and return that string. Now i made an object of a class in class library.

When i call that web method and pass this object. An InvalidOperationException generated, with error message There was an error generating the XML document.

I can not solve this, i search it on web but no solution found. I can not know how to upload the code here.

Please help me if any one can.

Alright I have been asked to create a rather particular website. to meen it lookes like I need to create frames. Seemless frames. The issue is I have no real clue as to how to go about doing this. The top and sides of the website need to always remain as they are while the middle frame, the content, needs to actually be a completely different website. I am doing work for sub contractors of this business

http://www.kenthomes.com/

This sub business is making a website (through me) and the main business (kent homes) wants all the contact to be from their site. Below is a link to an image visually depicting what needs to be created. the green section needs to be the ACTUAL kent homes website and the blue and red sections need to be the sub vendors header image and sides. "Frames" Can anybody tell me how I can overcome this issue?

I tried the frame thing but dreamweaver freaked out on me saying I dont have 4 certain pages. The ones linked in the frameset. I read some stuff on w3schools and tried something involving and it seems to be working alright. Thank you for your solution though. If I have more questions, which I probably will as this is all new to me, I will contact you. Thanks again mrMercury!
