如何编写一个JavaScript文件来验证ASP页面中的文本字段?

how to write a javascript file to validate text field in asp page?

推荐答案

尝试使用jQuery:

Try using jQuery:

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">

(document).ready(function(){ var textbox = document.getElementById('<％ = TEXTBOX.ClientID ％> '); var button = document.getElementById('<％ = SEND.ClientID ％> ');

(document).ready(function(){ var textbox = document.getElementById('<%= TEXTBOX.ClientID %>'); var button = document.getElementById('<%= SEND.ClientID %>');

(SEND).click(function(){ //在这里进行验证 }); }); < /script >

(SEND).click(function() { // do validation here }); }); </script>

上面的SEND是一个asp.net按钮控件.此处的逻辑是在单击发送"按钮后验证文本框.尝试学习jQuery.比javascript
更容易

最好的问候，

the SEND above is an asp.net button control. The logic here is to validate the textbox upon clicking the SEND button. Try studying jQuery. Its easier than javascript
