Javascript - Accessing HTML Checkbox In Code Behind?

Nov 6, 2011

I have a HTML checkbox which will perform a simple validation on another textbox, so the textbox will only be enabled if the checkbox is checked, but I also want to access this checkbox control in code behind to check and uncheck it. I don't think I can use the runat="server" because on the onClick event which will cause ('<%=uitxtVouTypeRedeemValue.ClientID%>') to be output as plain text.

<input type="checkbox"
onclick="document.getElementById('<%=uitxtVouTypeRedeemValue.ClientID%>').disabled =(this.checked)?0:1" id="uichkVouTypeRedeemable" />

Grid View Checkbox And Javascript Not Informing Server Side Code

May 6, 2011

I've got a asp.net gridview and inside of the grid view I have a check box at the header of the grid view like so: [Code] This gives me a nice little check box at the top of the grid view, the event OnCheckedChanged calls a function called SelectAllRows that looks like this: [Code] So if I click this header checkbox it checks all of the items in the gridview, and if I uncheck it, it unchecks all the items in the gridview. This works fine...but what doesn't seem to work is if the page loads up and I check the grid view header checkbox to true and it selects all the items in the gridview, then i click a button such as a DELETE button that calls some server side code. That code simply loops through the grid view and checks if the checkbox has been checked, if it is it calls code to delete an item.

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.

What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.

Here is the source that I am getting using Firefox's Firebug to inspect the element:

<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

[Code]...

Why would the two be showing me two different versions of the HTML?

And how would you be able to grab that source to view in a picturebox using webclient?

.net - How To Set ASP Checkbox State With Javascript

May 1, 2012

In a VB.net app, I have several checkboxes created with regular ASP controls, i.e.asp:CheckBox ID="cb3" runat="server" Checked="true" />I'm trying to implement a "Select all/none" functionality but I'm having a few problems. The Javascript is not changing the state of the checkboxes in Internet Explorer (v9). I tried debugging with IE's dev tools and the checkboxes are definitely getting their checked property set to true. (Also tried setting to "checked".) Here is the JS:

function setCheckboxes( state )
{
var inputs = document.getElementsByTagName("input");

Javascript - Accessing Elements Of JSON Object Without Knowing The Key Names

Feb 25, 2011

Here's my json:

{"d":{"key1":"value1",
"key2":"value2"}}

Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?

The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?

Here's an outline of my webmethod:

<WebMethod()> _
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)

Clicking A Checkbox That Requires Javascript?

Sep 8, 2011

On a webpage they have a checkbox that has an onchange, assuming this is javascript from my past knowledge. However in VB.NET when i click this checkbox by id, name, or even class it doesn't trigger the onchange to tell there webpage that the box is checked.

I'm assuming that i need to use javascript to tell the webpage that the checkbox is checked or somehow implement a browser or java itself into the webbrowser if that is the problem.

Here's the HTML code:

<td bgcolor="#FFFFFF" class="col2">
<input type="checkbox" onchange="updateCheckBox(this); validateNew('openAccountNewUserForm',this);" class="check" name="checkTermsOfUse" id="checkTermsOfUse">

I am having trouble extracting links from a web page and it involves javascript running on a website that contains the url links i need. I have encountered this issue before and was able to resolve it by getting the javascript file and then parsing it for the links. However this time I am unable to find the javascript that contains the links.To better clarify here is the source code segment from the web page:

VS 2008 : Get Javascript Generated HTML From WebBrowser?

Jan 15, 2011

I'm loading HTML into the web browser control, and adding a bit of javascript that hightlights a section of html when the user clicks on the area, by changing the classname. If you know the FireBug addin for Firefox, it's very similar to that. But what I need to do after this, is take the HTML source, and find where they clicked. But when I get the DocumentText of the webbrowser control, it's the original source. Not the source with the added class name.Is there a way to get the source code with the javascript generated html?

VS 2008 Parse JavaScript Onclick From HTML?

Feb 23, 2010

I have a webpage I would like to parse but not too sure how to capture the links activated by clicking on links. I have take suggestions about using regex to capture the onclick statements but that does not seem to help since it does not capture anything. Here is an example of what the html contains:

<li><a href="#" onClick="SelGenre('001'); return false;">プライベート</a> (4235)</li>
<li><a href="#" onClick="SelGenre('002'); return false;">なかま</a> (1121)</li>
<li><a href="#" onClick="SelGenre('003'); return false;">ペット</a> (398)</li>
<li><a href="#" onClick="SelGenre('004'); return false;">美容と健康</a> (956)</li>

Now if I capture 'SelGenre' and try and normalize that with the webpages root etc it does not work. Clicking on the link will display other links that I need to capture.I thought it may contain some javascript file but it did not even after trying to use firebug.

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

I am trying save a value from an input tag in some HTML source code. The tag looks like so:

<input name="user_status" value="3" />

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.

Retrieve HTML Of External Javascript Popup Window?

Aug 13, 2011

I was offered this interesting scenario by a visitor of my site and have been trying a few approaches, but not seeming to get it quite right. I have a Form with a WebBrowser control (or an AxWebBrowser if that works too) and on the page loaded in the browser, is a link that uses javascript to open a new popup window.This popup window I am unable to take "ownership" of and it launches in a new instance of the user's default browser (IE for this scenario). I need to then interact with that javascript popup window which now is not part of my application. If I needed to set a value of an input box on that form, how would I accomplish that if I can't "interact" with the form?
