需要ActiveXobject的跨浏览器替代方案 [英] Need a cross-browser alternative for ActiveXobject

问题描述

您好我正在使用此代码片段

Hi I am using this code fragment

var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.OpenTextFile(dir + "modules.txt", 2, true, -2);
s.WriteLine(tobewritten);
s.Close();
fso = s = null;
//alert (s);
if (s = "null")
    alert("Records updated");
window.location.href = 'main.html';

这对 IE 。但我需要一个解决方案，让它在 Firefox 中运行。我该怎么办

推荐答案

浏览博客 - 跨浏览器的XMLHttpRequest [ ^ ]

Go through the Blog - Cross browser XMLHttpRequest[^]

引用：

try {
    // test to see if XMLHttpRequest is defined
    XMLHttpRequest.DONE;
}
catch (e) {
    XMLHttpRequest = new Object();
    // define also all the constants
    XMLHttpRequest.UNSENT = 0;
    XMLHttpRequest.OPENED = 1;
    XMLHttpRequest.HEADERS_RECEIVED = 2;
    XMLHttpRequest.LOADING = 3;
    XMLHttpRequest.DONE = 4;
}

/** Creates new instance of the XMLHttpRequest object */
XMLHttpRequest.newInstance = function() {
    var xmlHttp = null;
    // use the ActiveX control for IE5.x and IE6
    try {
        xmlHttp = new ActiveXObject("MSXML2.XMLHTTP");
    } catch (othermicrosoft){
        try { 
            xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
        } 
        catch (native) {
            // If IE7, Mozilla, Safari, etc: Use native object
            xmlHttp = new XMLHttpRequest();
        } 
    } 

    return xmlHttp;
};
