ajax在firefox中可以正常执行，ie6中不能执行

  rt
  var request = false;

try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}

以上代码ie6下可以。可能是其他的问题

我可以把有影响的代码贴上来 全贴的话太长了 大家也未必愿意看

把代码全弄出来吧. 这个代码确实没问题.

测试代码：

demo01.php
JScript code:

<script src="demo02.js"></script>
<form>
<input type=button value="ok" onclick="a()">
</form>


demo02.js
JScript code:

var request = false;

try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP&qu
