本文介绍了Javascript无法在Firefox中运行，但在IE中可以正常工作.的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

function GetData() { var objXML,bNewData,strUserID,strCoID,strAdmin; var strUserName,bNewData; var strSQL,objNode,xmlDoc; var xmlhttp; var objNode,objNodes; strUserID = Form1.txtUserID.value; strCoID= Form1.txtCoID.value; strAdmin= Form1.chkIsAdmin.checked; doClearTable(document.all.tblUsers); strSQL = 'url'; bNewData = false; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET",strSQL,false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; objNodes=xmlhttp.evaluate(xmlDoc,xmlhttp,null,null,null); for(objNode=0; objNode<objNodes.length; objNode++) { strUserName=objNodes[objNode].selectSingleNode("UserName").text; strUserID=objNodes[objNode].selectSingleNode("ID").text; doAddSingleUserRow(strUserName,tblUsers,strUserID); } } //

上面的Javascript方法在IE中工作正常，但在Firefox中不工作. 如果有人能解决?在Firefox中，ResponseXML给出了undefined.

Above Javascript method is working fine in IE but not working in Firefox. If anyone can solve? In Firefox, ResponseXML gives undefined.

推荐答案

好，您对XMLHttprequest的实现还不完整.在尝试访问/使用responseXML之前，您需要检查各种状态. 请查看以下链接，以了解有关实现的更多信息以及应该在其中进行的各种检查: XMLHttpRequest对象 [ ^ ] 带有示例的XMLHTTPRequest [ ^ ] 使用XML HTTP请求对象 [ ^ ] Well, your implementation of XMLHttprequest is not entirely complete. You need to check for various status before trying to access/use the responseXML. Have a look at these links to know more about the implementation and various checks that should be there: XMLHttpRequest Object[^] XMLHTTPRequest with Sample[^] Using the XML HTTP Request object[^]

用"xmlHttp.responseText"替换"xmlhttp.responseXML" Replace "xmlhttp.responseXML" by "xmlHttp.responseText"
