I have a gridview that displays client data. The first column on each row for the gridview is a checkbox. The second column on the gridview is client name and the third column is account holder. The user can select checkboxes (on multiple rows) to modify data (account holder).
I want to add clientName column value in a comma delimited string to a hiddenfield on my page. How do I do that using javascript, as I do not want to use postback and looping through each row on the grid to get the checkbox status. When a checkbox is checked, it should append the hiddenfield value.
I am getting the hiddenfield value as blank no matter what checkboxes are checked. I also know that my code is not targeting the correct row to get ClientName (row where checkbox is checked).
function RowClick(CheckBox)
{
var BaseControl = document.getElementById('<%= this.myGrid.ClientID %>');
var TargetControl = document.getElementById('MyHiddenField');

I've been having a lot of trouble trying getting the following code to work, all the examples that I have seen tell me that it should, but it doesn't and i'm out of ideas.
if (parent.input_frame.input_form.cheque_number.value.search(/./) != -1)
{
alert('The cheque number is invalid.');
parent.input_frame.input_form.cheque_number.select();
return;
}
What I want it to do is alert the user that the cheque number they have entered is invalid if it contains a period / full stop / dot.
The problem is that it always says the cheque number is invalid no matter what the user enters.
I have spent the last hour or two trying a number of things using just about all the regex functions and examples in the JavaScript book I have and examples from other posts on this site, but still cannot get it to work.
If you could let me know what I am doing wrong or provide me with an example of another way to do this that would be great.
Browser is Internet Explorer, have tried /D/ as the regex too, but this did not trigger the alert when a number with a dot was entered.
I found this for instant search :

AB1.2CD34
I need to split the string into groups of letters and numbers..

What is the best way of doing this ?
I've looked at string.split using a regex, but that doesn't output the
delimiters.

I would like to strip HTML out of a string I have in a JSON item I have. I'm using Yahoo! Pipes to aggregate several blog-feeds and put them in together in one big feed, I then use jQuery to parse that JSON and place it onto my page. My issue is though that what's being parsed onto my page is the raw html code within the JSON item. I want any HTML related tags out of the item, so I just see text.

I am using javascript to search for the '*' character in a string (ie. 'username*:') but using search('*') does not work. How do I search for it since the search function takes a regexp argument and * messes that up?

this function is supposed to search a string for decimals and tell me how many of them it has found, but for some reason, it's not doing it right. since the "period" character is a special character in regular expressions,I went ahead and escaped it, but it's still doesn't work.
function ImprovedFormatAmount(ElementId)
{
var oElement = document.getElementById(ElementId);
var ElementValue = oElement.value;
var DecimalRegXp = /./g;
var OutputValue = ElementValue;
if (OutputValue.length > 0)
{alert (OutputValue.search(DecimalRegXp));}

Examplemystring would be something like this<parent><child1>1 & 2</child1><child2>1 & 2</child2><child3>1 & 2</child3></parent>I need to replace the & symbol in child2, but not 1 or 3. I am trying to figure out how to replace just any & signs in child2, but I need to leave them alone in child 1 and 3.I know I can do a replace(), but just not sure how to limit it to only the one I need

I'm writing a piece of JS code that returns a result of true if the pattern appears in string as a substring (case sensitive) but would like to extend its functionality to returns true if all the individual characters of pattern appear in string (regardless of order).

For example:This is what the program currently does:
match1("adipisci","pis") returns true
Whereas I would now like it to do this:
match1("adipisci","sciip") returns true
match2("adipisci","sciipx") returns false because x does not exist in variable
match3["adipisci","adipisci"] returns true in array 1 and 2 if "sciip" is searched
match4["adipisci","adipiscix"] returns false in array 1 and true in array 2 if "sciipx" is searched
