Java脚本在某些浏览器中不起作用 [英] java script not working in some browsers

问题描述

大家好，
我有这样的脚本:
崩溃

Hi All,
I have script like this:
Collapse

<script type="text/javascript">
        function count(txt)
       {
          var textchar='<%= TextBox2.MaxLength %>';
          var textbox=document.getElementById(txt);
          var lbl=document.getElementById('<%= Counlbl.ClientID %>');
          if(textbox.value.length>textchar)
          {
          textbox.value=textbox.value.substrung(0,textchar);
          }
          lbl.innerText=textchar-textbox.value.length+" Characters remaining..";
       }
   </script>

此脚本可以在Internet Explorer中工作，但不能在Mozilla Firefox中工作，我还把最大长度设置为120个字符，超过长度后会引发异常

1.如何防止此异常
2.如何使此脚本在Firefox中运行.

谁能帮我.

在此先感谢

2.How can i make this script to work in Firefox.

Can any one please help me.

Thanks in Advance

推荐答案

需要更改以下几项:

1."substrung"应为"substring"

2.也可以使用"innerHTML"而不是"innerText"在Firefox中运行.

您没有说明异常是什么，所以这可能无法解决您的实际问题.

There are a couple of things to change:

1. "substrung" should be "substring"

2. use "innerHTML" instead of "innerText" to work in Firefox too.

You didn''t say what the exception is, so this might not solve your actual problem.

问题1:您可以使用try ... catch ...来防止异常

问题2:您可以在脚本中使用jquery lib.这是一个出色的js库和交叉浏览器.
