Modify The POST Data In Javascript?

Sep 29, 2010

I have a scenario like below:I navigate to the reader page with the below form data

<form id="mainForm" action="Reader.aspx" method="post">
<input type="hidden" id="bookId" name="bookId" />
<input type="hidden" id="startPageId" name="startPageId" />
</form>


Initially the hidden variable values will be bookId=1 and startPageId=5

I navigate between the pages by using javascript and assume the startPageId will now change to 8.I want the new value to be stored in the above form data and want to submit the same page with different form data

bookId=4
startPageId=10

When I click on the browser back button, I want the user to be navigated back to the BookId=1 and startPageId=8

Retrieving JavaScript Data From A Post?

Oct 19, 2010

I'm using the WYSIWYG editor TinyEditor (http://www.leigeber.com/2010/02/javascript-wysiwyg-editor/), and I'm having an issue recalling the updated data. I searched the forum and found someone else had the same issue:

http://forums.asp.net/p/1526709/3684896.aspx#3684896?Accessing+textarea+value+in+code+behind

Thing is, I think I've done everything in the post, but my code is just not working. When I click submit, the variable in the code behind (val) isn't capturing any data
- Object reference not set to an instance of an object.

Here's my code:

Javascript - Post Json Data On Full Postback?

Nov 24, 2010

I wonder if I have any other method but a hidden field to post a JSON object to the server on full postback.

Imagine you have a form (with textboxes, checkboxes, etc) and you need to post a json string when the user post the form. This means, I would post all the form values + the json string but I can't come up with any solution but a hidden field.

Modify Every File That Contains A Javascript Reference?

Mar 24, 2010

I have some pages that reference javascript files.

The application exists locally in a Virtual Directory, i.e. http://localhost/MyVirtualDirectory/MyPage.aspx

so locally I reference the files as follows:

<script src="/MyVirtualDirectory/Scripts/MyScript.js" type="text/javascript"></script>

The production setup is different though. The application exists as its own web site in production, so I don't need to include the reference to the virtual directory. The problem with this is that I need to modify every file that contains a javascript reference so it looks like the following:

<script src="../Scripts/MyScript.js" type="text/javascript"></script>

I've tried referencing the files this way in my local setup but it doesn't work.

C# - To Intercept And Modify The Html Output Stream In .net, To Combine The Javascript?

Jan 5, 2011

Is there some way to intercept the HTML output stream in asp.net and make modifications? Eg using httpmodules or something? I know this is possible using java servlets and assume there must be an elegant way to do this with asp.net.

My purpose is to combine the many javascript files into one composite script which has been minified/packed, to make the page load faster.Eg, if my page normally outputs the following in the page head:

<script type="text/javascript" src="/scripts/blah.js"></script>
<script type="text/javascript" src="/scripts/yada.js"></script>

I want to replace that with the following:

<script type="text/javascript" src="/scripts/all.js"></script>
(also i realise i'll have to create all.js somehow).

Update Javascript After Async Post Back In C#?

Feb 4, 2011

I have the following code on my website:

<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger controlid="myButton_btn" eventname="Click" />
</Triggers>
<ContentTemplate>........

The javascript is running everytime I click the button. However, even though my subroutine updates the session variable after clicking the button, I always get the same alert. In other words, the same javascript is run after postback, and it is not updated. I am positive that the session variable IS being changed.

Javascript - Dynamically Change Form Post URL?

Aug 24, 2010

I want to make the results of an ASP.NET form POST "bookmarkable", and I'm thinking of using query parameters to accomplish this. The idea is that a user will visit http://domath.com and they will type in a math problem, and view the results. The query and results are visible at http://domath.com?ProblemID={some guid here}The only part I don't really know is how do I change the target of the form URL since I'm using a POST instead of a GET..Here are the options I came up with, and I'm not sure what is practicalSubmit form as usual, server redirects to a URL with the new parameters attached Use a webservice or callback to get new URL. Javascript then updates form target
