guys;
I need to add a hidden input at run time. I used the following code:
var hiddenInput = document.createElement('input');
hiddenInput.type = 'hidden';
hiddenInput.name = 'hiddenInput';
hiddenInput.value = 'somevalue'
this code should generate the element:
<input type="hidden" name="hiddenInput" value="somevalue" />
but it generates the element:
<input type="hidden" propdescname="hiddenInput" value="somevalue" />
could you please help me with this?

This is an unfortunate but known issue. If you run this code in IE it will actually create an input with the code below:
<input type="hidden" submitName="hiddenInput" value="somevalue" />
The only way I know to fix it is appending the HTML code manually to the parent node in the dom tree. That way you will be able to set the name properly.

Ok, so back to your question;
You can use the object onChange to call a javascript function to validate the content as each element changes.
You could also use a button when you submit to check each element. The code below is a sample to help you get going, but there are heaps of examples on the net. You could take all the javascript out of the lower script block and place it in a reference file as shown in the upper script block entry
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript" src="js/thejsfile.js"></script>
</head>
<body>
<table>
<tr><td>Name:</td><td><input id="textName" type="text" onchange="validateName()"/></td><td id="nameValidMessage"></td></tr>
<tr><td>Age:</td><td><input id="textAge" type="text" onchange="validateAge()"/></td><td id="ageValidMessage"></td></tr>
</table>
<input id="ButtonGo" type="button" value="Go" onclick="go_click()"/>
<script type="text/javascript">
function validateAge() {
var valid = false
//write you code to validate the age
//set valid to true if all ok
if (textAge.value == "99") { valid = true; }
//update the page message
if (!valid) {
ageValidMessage.innerHTML = "Invalid Age";
}
else {
ageValidMessage.innerHTML = "";
}
return valid
}
function validateName() {
var valid = false
//write you code to validate the name
//set valid to true if all ok
if (textName.value == "Dave") { valid = true; }
//update the page message
if (!valid) {
nameValidMessage.innerHTML = "Invalid Name";
}
else {
nameValidMessage.innerHTML = "";
}
return valid
}
function go_click() {
var valid = false
//Do a validation of Name and Age
valid = validateName() && validateAge()
if (valid) {
//Do what you need to if all ok
}
}
</script>
</body>
</html>

Hi all,
I'm trying to parse a web page that shows dinamically some data (is a web game page) that is not contained in the code behind the page (the one that I access using the Chrome developers tools, for example).
I see that I can show this data even detaching my pc from the network, simply selecting an item in the combobox, but the content appears in the page source only when the selected combobox item is changed.
Anyone can suggest me where I can find the hidden data or source code?
Thank you
Leo

If you are viewing the page with Chrome you can right-click on the item and select Inspect element to see how the item is presented.
|
|
|
|
|
I know this. What I'm looking for is the data that is in the memory of the browser, downloaded from the web server, but presented when the javascript inside the web page decide to show it.
This kind of data is not visible simply using "Inspect element".
|
|
|
|
|
As far as I am aware, you can examine elements of the HTML DOM tree but I do not know of any method to access the browser's memory.
|
|

In Chrome you can view the values of javascript objects.
After you 'Inspect Element' to load up the Source, look for the javascript objects in the code behind files and then in the Chrome console if you type the object name it will tell you the value. Remember to look at the Scripts tab and you can change between all the referenced javascript source files to inspect them.
If you come across any files that have been minified, you can click the {} (Pretty Print as google call it) button at the bottom and it will make the source more readable.
You can also change the value and also run any JS functions, JQuery against the DOM and all sorts. You can also change attributes and values of the CSS if you are doing testing etc.

I thought about that this morning, was considering writing a Beginners guide to Browser debugging article........

That would be super useful.

Ok, i've already started.......... may take some time, trying to get the structure and appropriate content is a challenge!

Ok, this is the right reply
I've written some C# code to access this data using a WebBrowser object.
Are you interested in?

Good Day All
in my page i have a hyperlink button in a gridview defined like this
<a href="#" onclick="<%# String.Format("return showComment('{0}','{1}')", Replace(Eval("Field1").ToString(),Chr(13),"<BR>"), Replace(Eval("Field2").ToString(),Chr(13),"<BR>") ) %>">
<img src="../../Imgs/comment2.png" />
</a>
and the Function showComment is defined like this
function showComment(CommentPend,CommentCancel)
{
$("#btnclose").unbind();
$("#divPendComment").center();
$("#divPendComment").fadeIn('slow');
$("#txtcomment").val(CommentPend.toString().replace(/^[a-z0-9 ]$/i, ''));
$("#txtcommentCancel").val(CommentCancel.toString().replace(/^[a-z0-9 ]$/i, ''));
$("#btnclose").click(function (e)
{
$("#divPendComment").fadeOut('slow');
e.preventDefault();
});
return false;
}
now as you can see i am trying to get rid of the special characters like the carriage returns but still i get a a javascript error when this link is clicked
Uncaught SyntaxError: Unexpected token ILLEGAL
thanks

It means you've committed a crime. Be prepared for arrest.

lol indeed a string with special characters is a crime , especially the carriage return

I am not 100% sure what you are trying to achieve, but replace(/^[a-z0-9 ]$/i, '') is probably not what you intended: It says "If the whole field consists of a single letter, digit or space then set it to an empty string; if it is not just a single letter, digit or space, keep the whole lot as seen". My guess is that you want all non-letter/digit/space chars to be blanked out. Try replace(/[^a-z0-9 ]/ig, '').

Good Day All
i have a Jquery code defined like this
$(".cnt").focus(function()
{
if(this.value == this.defaultValue){
this.select();
}
});
and i am creating a textbox on fly and after creating it i bind data to it and after that i want to attach a focus event if there a value "0" on it
If cnt.Text = "0" Then
cnt.CssClass = "cnt"
End If
but still when i select a textbox that has "0" it does not select the whole content of the textbox. i went through a breakpoint and it goes through this line
cnt.CssClass = "cnt"
Thanks
