Hai,

Iam designing an email page.I have a textbox where i will enter email addresses.So when there are multiple email's,when i click on backspace instead of removing letter by letter..i have to remove a mail id itself..

For example,

In my textbox iam having mail id's like

abc@gmail.com,xyz@gmail.com,sss@gmail.com

if i click on backspace i have to remove sss@gmail.com at a time instead of removing letter by letter.

Iam trying to do this in asp.net.

Please help me in doing this.

Solution 2

You would need to attach an event handler for onkeydown of your text box.

<input type="text" id="txtEmail" önkeydown="myFunction()" />

your javascript function can be like this

C#

function myFunction()
{

if(event.keyCode == 8)
{
var result = "";
var emails = document.getElementById('txtEmail').value.split(",");
for(var i =0; i < emails.length - 1; i++)
{
   result += emails[i] + ",";

}
document.getElementById('txtEmail').value = result;
}

}

You can get the index of email id to remove by getting your currrent cursor position
I think this might help
