Question

vs08中建了个js文件中,但不知道如何写脚本，谁有这方面代码给小弟一份，我就是想在js文件中判断用户注册时的验证，本来想用验证控件，可听说验证控件在用的浏览器上不好使，所以想用JS脚本  - -！

//1.我们首先创建一个全局变量
    //2.我们在创建一个XmlHttpRequest对象
    var xmlHttp;
    
    function createXmlHttpRequest()
    {
        if(window.XMLHttpRequest)
        {
            xmlHttp=new XMLHttpRequest();
        
            if(xmlHttp.overrideMimeType)
                {
                    xmlHttp.overrideMimeType("text/xml");
                }
        }
        else if(window.ActiveXObject)
        {
            try

Answer 5

验证类。。http://www.360doc.com/content/06/1019/13/12224_234413.shtml

Answer 6

直接写js函数呗.。   写了然后往你想要验证的页面引用这个Js文件就可以直接在页面里面调用那些函数了.。  

Answer 7

lz,如果客户端屏蔽掉了JS验证呢？
