推荐答案
您可以在onblur事件的帮助下实现离开事件。附上第二个文本框的onblur事件，现在当用户离开第二个文本框时，onblur事件事件将被触发，您可以根据您的要求在此事件中执行任何操作。
参见onblur事件示例：
Link 1 [ ^ ]
< a href =http://www.w3schools.com/jsref/event_onblur.asp>链接2 [ ^ ]
You can implement leave event as you are saying with the help of onblur event. Attach onblur event of your second textbox, now when user leaves second textbox, onblur event event will be fired and you can do ehatever you on this event as per your requirement.
see example of onblur event:
Link 1[^]
Link 2[^]
Textbox TextChanged没有触发。虽然我给了Autopostback ='True
Textbox TextChanged is not firing.even though i gave Autopostback='True"
你可以这样做
you can do like
<html>
<head>
<script>
function myFunction()
{
var val1=document.getElementById("txtid1");
var val2=document.getElementById("txtid2");
var total="";
if(!isNaN(val1 ) && !isNaN(val2)){
total=val1+val2;
('txtid3').html(total);
}
}
</script>
</head>
<body>
<p>A function is triggered when the user is pressing a key in the input field.</p>
<input type="text" onkeypress="myFunction()">
</body>
</html>
