Am facing a very strange issue.
I've a hidden fields as shown below.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:HiddenField ID="hid_test" ClientIDMode="Static" runat='server' />
</div>
</form>
<script language="javascript" type="text/javascript">
$(function () {
alert($('#hid_test').val());
});
</script>
</body>
</html>
And in server side am setting a value to the hidden field as follows
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
hid_test.Value = "abcd"
End If
End Sub
Very simple code. So in the first run the alert shows as "abcd" since am setting that from server side. OK.. Thats fine.
Then what I did was I changed hidden field value using jquery from console as below
$('#hid_test').val('12');
After this change does when I hit F5 (Page reloads) obviously my server side code hits and the hidden fields value should be changed to abcd
But when the page loads the alert says 12 itself. Means its keeping the value set from client side. Any kind help appreciated. Am testing in Firefox.
I disabled FF form fill feature as follows
Firefox auto-fills forms with previous values by default. If you turn off the feature, you should stop seeing that behavior. This question and its answers seem to suggest there's no simple way to tell Firefox not to do that in the HTML; instead, the answers there focus on using JavaScript on load/unload to set the field values (e.g., on load to overwrite what Firefox auto-filled; on unload to encourage Firefox to remember the values the page author wants remembered).
Add the autocomplete="off" tag.

I have a asp.net web page that im creating. and have a vbscript as the client side script. and the application will be accessed only from IE so thats not an issue. I get a weird error when i click on a button which is supposed to execute the client side vbscript instead it throws me a javascript runtime error?.
Is there a way to configure this ?.
By the way im moving from a HTA to asp page if someone can direct me as to how to implement this will be appreciated.
This is the html code for the button element
<input type = "button" value = "Display" name = "Run_Button" onClick = "getvalue">
This is the code for the client side vbscript
<script language="vbscript" type="text/vbscript">
Sub getvalue
some text
End sub
Am i missing something? further i added the below line at the start of the html document
<%#language="VBScript"%>
VBScript is no longer supported in IE11's "edge" mode, which your page will be rendered in if you're specifying <!doctype html>. You'll need to make a few changes to your webpage.
First, add the following <meta> tag to your <head> section:
<head>
<meta http-equiv="x-ua-compatible" content="IE=10">
</head>
Second, all event handlers are considered to use JavaScript by default, so you'll need to call your function in one of two ways:
Using JavaScript syntax (note the added () to getvalue):
<input type="button" value="Display" name="Run_Button" onClick="getvalue()">
Explicitly specify that you'll be using VBScript (no need to use () on getvalue):
<input type="button" ... onClick="getvalue" language="VBScript">
I need to put some javascript absolutely in the <head> block of the page -- it must execute before the rest of the page because a possible outcome of the script is to redirect to a different page.
However, when I use RegisterClientScriptInclude (to put some jQuery in there) and RegisterClientScriptBlock for my code which uses the jQuery, it puts it near the top of the <body> block, and it does not execute. I can't see a way to programmatically put this javascript into the <head> block -- it must be programmatically because sometimes I don't want it there, and sometimes I do.
I've tried to see if I can directly reference Content1, the ID of the asp:Content element corresponding to the <head> block, but no go.
Just in case anyone thinks that RegisterStartupScript might work: it doesn't. It puts it lower in the <body> block than everything else. Oddly enough.
Want some code? Here:
Type csType = this.GetType();
ClientScriptManager clientScript = Page.ClientScript;
if (!clientScript.IsClientScriptIncludeRegistered(jqueryScriptName))
{
clientScript.RegisterClientScriptInclude(jqueryScriptName, "~/Scripts/jquery-1.7.1.min.js");
}
if (!clientScript.IsClientScriptBlockRegistered(citrixDetectorScriptName))
{
clientScript.RegisterClientScriptBlock(csType, citrixDetectorScriptName, citrixDetectorScriptText, true);
}
By popular demand, how I detect the ActiveX component. This is JScript.
try {
var icaObj = new ActiveXObject("Citrix.ICAClient");
var CitrixVersion = icaObj.ClientVersion.split(".");
var MajorMinorVersion = CitrixVersion[0] + "." + CitrixVersion[1];
if (MajorMinorVersion == "11.0") {
// Citrix is OK
}
else {
window.navigate("WrongCitrix.aspx?Citrix=" + MajorMinorVersion);
}
}
catch (e) {
window.navigate("NoCitrix.aspx");
}
If the ActiveX component is not present, then redirection is a page that tells the user they need to install it. If the ActiveX component is any other version than 11.0, then the redirect is to a page that explains this and how to deal with the situation (backrevving for example).
An prior check during page load checks to make sure they have Internet Explorer v4 thru v9, because any other version will not work with the product (and IE10+ will crash if it even tries to load v11.0 of the ActiveX component).
If I understand your question, you can insert PlaceHolder control wherever you want inside the page.
<%# Page Language="C#" AutoEventWireup="True"
CodeBehind="Default.aspx.cs" Inherits="WebApplicationTelerik.Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script type="text/javascript"
src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<asp:PlaceHolder runat="server" ID="PlaceHolder1"></asp:PlaceHolder>
</head>
<body>
<form id="form1" runat="server">
</form>
</body>
</html>
protected void Page_Load(object sender, EventArgs e)
{
PlaceHolder1.Controls.Add(new LiteralControl(
"<script type=\"text/javascript\"> alert('here'); </script>"));
}
document.GetElementsByTagName("head")[0].appendChild( newScriptNode );
or jQuery
$("head")[0].append( newScriptNode );
If you really must insert JavaScript into the head tag, you can just make it an ASP.NET control and insert a control into it's child collection.
E.g. In the ASPX file:
<head runat="server" id="header">...</head>
In the code behind:
header.Controls.Add(new Literal("<script type='text/javascript'>...</script>"));
Although I do think you need to think about your process, it would be more efficient to redirect the user in the back-end before the page is rendered.
Oh and RegisterStartupScript correctly places your JavaScript after your html for increased load performance.
I have a weird bug that is present only in IE (7/8/9/9CV).
FF and Chrome do not have this issue.
I have a pretty big, complex page. In the bottom of the page I have two pieces of JavaScript code right one after another. The first one has no problems, but the second one for some reason is being displayed as a text when I load the page first time. If I just refresh the page without doing anything else - everything works and looks just fine.
Two pieces of JS being generated on a server from two different pagelets so I cannot put them together into one script tag. The first piece of JavaScript code is nothing more but a call to the same function couple of times with different parameters, and the second script is just a declaration of a JSON like object that is being consumed by another function that is defined earlier on the page.
So the page code looks something like this:
<!DOCTYPE html>
<html>
<head>
...
<title>...</title>
</head>
<body>
...
<script type="text/javascript">
//Some javascript that executes perfectly fine every time and is nothing more but just couple of calls to some function
someFunction("param1");
someFunction("param2");
someFunction("param3");
</script>
<script type="text/javascript">
var myObject = {"success":[{"header":"Form successfully submitted","messages":["Some message 1"]}]};
</script>
</body>
</html>
So when a form submitting happens I take this object and use it to display a message on the page. But instead, when user submits the form and it opens the page for the first time, I see this in the bottom of the page:
var myObject= {"success":[{"header":"Form successfully submitted","messages":["Some message 1"]}]};
But when I refresh the page - I do not see that code, but instead I see the message being displayed with values from this object.
When I open the "developer tools" and navigate to the HTML tab, I see that my tag for the second JS piece is shown as commented out!
<!-- sctipt ... -->
But if I refresh the page - it works fine, and in HTML tab of the developer tools it actually shown as a script node that I can expand and see the Javascript code.
Does anyone know what is going on here?!?! This issue has been bugging me for couple of days now!
You should replace
<script type="text/javascipt">
with
<script type="text/javascript">
EDIT :
HTML isn't XHTML. Don't wrap your scripts inside CDATA. Your script elements should be simply like this :
<script type="text/javascript">
var t0_date = new Date();
...
</script>
Change both these:
<script type="text/javascipt">
to:
<script type="text/javascript">
Well, I found an answer to this problem. Well, more of a work around I guess, as this is not something I expected but it works.
Basically, if you put anything between the two script elements - IE wokrs fine!
So what I did was - I put br tag in between and it now works fine. I have no idea why. Perhaps some weird bug in IE rendering engine.
The end result looks like this:
<script type="text/javascript">
//Some javascript that executes perfectly fine every time and is nothing more but just couple of calls to some function
someFunction("param1");
someFunction("param2");
someFunction("param3");
</script>
<br>
<script type="text/javascript">
var myObject = {"success":[{"header":"Form successfully submitted","messages":["Some message 1"]}]};
</script>
Following up from my solved [previous issue][1], I'm having trouble building a simple HTML Web resource containing some basic javascript, page is rendered correctly but script doesn't seem to work properly.
My HTML resource is very basic:
<html>
<head>
<script src="ClientGlobalContext.js.aspx" />
<script type="text/javascript" src="new_jquery_1.7.2.min" />
<script type="text/javascript">
function buttonClick() { alert('Yo !'); }
</script>
</head>
<body>
<input type="button" value="Test" onclick="javascript: buttonClick();" />
</body>
</html>
Although the page shows up fine, clicking the button yields The value of the property is null or undefined not a function object error like the functions wasn't there, but I checked via F12 console that the code is rendered correctly.
I also tried invoking the web resource via the direct url, in the form of
http://mycrmserver/myorg/WebResources/new_myResource
But (as I expected) the behavior of the page was the same.
I checked Google, I surfed a couple of other SO questions and MSDN and all state this is the right way to do it, what's wrong with my code ?
Other (not sure if useful) details:
If the F12 tool is open the error comes up as a SCRIPT5007 javascript runtime error in the console. If it's not, I get the usual script error notify popup if I browse to the webresource direct url, or nothing happens at all if I try to open the resource inside the CRM.
The CRM environment is updated to Rollup 3 (updating it is not an option unfortunately)
I'm using IE 9 (Remember: Dynamics CRM can't be used in non-IE browsers yet)
UPDATE
Shorthand tags confuse the CRM.
Basically this syntax sometimes gets messed up:
<script src="ClientGlobalContext.js.aspx" />
But this works perfectly:
<script src="ClientGlobalContext.js.aspx"></script>
Root cause is a missing script tag, despite the code you posted being correct.
CRM does some messing about with the HTML you post into the script editor window. What is rendered in the browser is this (note that the ClientGlobalContext.js.aspx tag is not closed in the same way as your pasted code):
<HTML><HEAD>
<SCRIPT src="ClientGlobalContext.js.aspx">
<script type="text/javascript" src="new_jquery_1.7.2.min" />
<script type="text/javascript">
function buttonClick() { alert('Yo !'); }
</SCRIPT>
<META charset=utf-8></HEAD>
<META charset=utf-8></HEAD>
<BODY><INPUT onclick=javascript:buttonClick(); value=Test type=button></BODY></HTML>
Resolution:
Add full "close" tags to each opening script tag (rather than using "/>").
I'm trying to use http://www.asual.com/jquery/address/ for history management, this works absolutely fine when we work on "a" tags, but now I've search module which trigger when I click on a search button and I'm trying to include the search text in the address(and also the page number), so that when the user uses the backs button he/she can also see what search they have done previously. Any help will be greatly appreciated.
Edited:
Reference - http://www.asual.com/jquery/address/
I'm building AJAX application, so all the modules are loaded using AJAX and to keep a track of the history I'm using: http://www.asual.com/jquery/address/, till now all the links are "a" href's which I'm coding as Public
Now, I'm working on the search page which has a search TextBox and a searchButton, so when the user enters in the text box and clicks on searchButton, the url has to be adjusted accordingly so when the user directly enters (or comes to that URL using BACK button), the search results should be displayed, this is similar to the "SEARCH MAIL" button in gmail, please note how the url is changing, here I'm also trying to achieve the same thing.
Hope it is clear, thanks.

I bealive you're looking for something like in this example.
Simplified example:
<html>
<head>
<title>jQuery Address Form</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="jquery.address.js"></script>
<script type="text/javascript">
$.address.init(function(event) {
$('form').address();
})
.change(function(e) {
// for anything that isn't homepage
if (e.value != '/') {
// load results for url in e.value, for example:
$("#results").load(e.value);
}
})
</script>
</head>
<body>
<div class="page">
<h1>jQuery Address Form</h1>
<form action="find.php" method="get">
<label for="input">Query</label><br>
<input id="input" name="input" type="text" value="" size="60"/>
<input id="submit" name="submit" type="submit" value="Submit"/>
</form>
<div id="results">
</div>
</div>
</body>
</html>
When you submit the form, the url is changing. The change event is then handled by my code. e.value is a url in this example, so when the url is changing we're trying to load search results into the #results div.
The same change handler is used when user navigates using the "back" button in his/her browser.
There exists whole jQuery plugin for that, called jQuery BBQ: Back Button & Query Library. Try out demo, and find if that is what you need.
