how to check a textbox value in jquery?

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net


I want to perform some action when an asp.net textbox value length is greater than 1 character. And for this I wanted to know how to write this check in jquery?

I have created a check like below-

if ($('[id=txtUserInput]').val().length > 2)
{ do some work...} 

But its giving me the following error

$("[id=txtUserInput]").val() is undefined

Can anybody let me know the right way of doing this?

Check All with JQuery and a Asp.Net GridView

Display a Grid on the screen with a checkbox in each row. At the bottom of the page have "Check All" button.

Typically if I need to do anything interesting I use a template column. So my GridView will look like the one below (most other columns removed for readability). The only interesting point to note is the CssClass="ApprovalCheckBox" in the CheckBox ItemTemplate.

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

Query DB and update Check Box List on JS/jQuery Function

Hey guys.  I'm not sure if this is the right forum to post this in but I've come to a roadblock in my app and I'm not sure which way I should go.  Currently, I have a slider control and two text boxes used to set the Start and End times of a section of a video.  Let's say the video is of some Music Awards.  In my database, I've tagged the start and end time of each celebrities on-screen appearance.  When the user adjusts their start and end times on the page, I want to query the database table and pull back all celebrities within that range.  The problem is I don't know how to do this in JS.Can I use the Check Box List and bind the values to it?  Do I need to render a table of Check Boxes in JavaScript?  Do I call the Server-Side code via Ajax and then partially render the page?Any help, comments or suggestions would be great.

How can you check the user is owned of the web site that is input in textbox?


Hi Experts.

In the most web sites when you want to register in any web sites, you must provide your information such as First name, last name, email and etc. Then the web site create a confirm link and send it to your mail. If you input your mail correctly, you can check it in your inbox of your mail and click on it to your registration is completed.

In this scenario, the users should input their mails correctly because the web sites will send the confirm link to it. In other words the mail that the users input must be owned of user else if they can't click on the confirm link.

Suppose you want the users input their web sites instead of their emails address in your web site, Now How can you check the user is owned of the web site that is input in the textbox?

I hope you understand my question else if tell me to describe it more.

When to check if something Is Nothing? How do you check an empty textbox?


I currently do something like...

If TextBox1.Text Is Nothing OR Trim(TextBox1.Text) = "" Then

jQuery having trouble finding textbox inside repeater


This is an ASP.NET 3.5 web app with a master/content page relationship. The content page contains a repeater with a textbox.  I am trying to use jQuery to attach a charcter counter function.  (This function works perfectly on other pages where the textboxes are not in a repeater.)  However, when the page runs, the following exception is thrown:

Compiler Error Message: CS0103: The name 'txtComments' does not exist in the current context

Source Error:

Line 11:         $(document).ready(function() {
Line 12:             //Set up the character counters
Line 13:             $("#<%= txtComments.ClientID %>").charCounter(1000);
Line 14:         });
Line 15:     </script>

This is the jQuery that is in the HeadContentPlaceHolder:

    <script src="scripts/jquery-1.3.2.min.js" type="text/javascript"></script>
    <script src="scripts/jquery.charcounter.js" type="text/javascript"></script>

    <script type="text/javascript">
        $(document).ready(function() {
            //Set up the character counters
            $("#<%= txtComments.ClientID %>").charCounter(1000);

This is a simplified version of the repeate
