推荐答案

new ActiveXObject("Microsoft.XmlHttp");


您只能在IE上创建activex对象.所有其他浏览器都不知道如何处理.

对于所有非IE浏览器，都有不同类型的ajax调用方法..自行查找，但看起来像这样:

new ActiveXObject("Microsoft.XmlHttp");


You can create activex objects only on IE. All other browsers don''t know how to handle them.

There is different type of approach of ajax calls for all non IE browsers.. look it up yourself, but it looks something like this:

var httpRequest;
if (window.XMLHttpRequest) { // Mozilla, Safari, ...
    httpRequest = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE 8 and older
    httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
