我放了一个文本框....我想对它加以限制..
不应允许在文本框中输入数字和特殊字符...
我怎么能在Javascript中使用onkeypress事件???
我的代码是......
<script>
function event()
{
document.getElementById("TX1").addEventListener("keypress", handleKeyPress, false);
}
function handleKeyPress(e)
{
var restricted = "0123456789_#!";
var key = e.keyCode || e.which;
var i=0;
for(;i<restricted.length;i++)
{
if (restricted.charCodeAt(i) == key)
{
e.returnValue = false;
}
return true;
}
</script>
<body onLoad="event();">
<input type="text" name="T1" id="TX1" size="27" maxlength="35" >
</body>
