在设计电子邮件页面时单击退格时删除电子邮件 [英] In designing email page remove email when click on backspace

问题描述

Hai，



我设计了一个电子邮件页面。我有一个文本框，我将输入电子邮件地址。所以当有多个电子邮件时，我点击退格而不是逐字母删除..我必须删除邮件ID本身..



例如，



在我的文本框中，我有邮件ID，如



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



如果我点击退格我必须一次删除[e-mail]而不是逐字删除。



我试图在asp.net中这样做。



请帮我这样做。

从后面的文本框中删除字符串 [ ^ ]

你会需要为你的文本框的onkeydown附加一个事件处理程序。



< input type =textid =txtEmailönkeydown=myFunction（）/ >



你的javascript函数可以是这样的

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

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;
}

}
