如何使用JS获取IE上传文件路径(IE7,8)

本篇文章是对使用JS获取IE上传文件路径的实现代码进行了详细的分析介绍需要的朋友参考下复制代码 代码如下:

function validateFileSize(id maxsize) {
var btnsave = documentgetElementById("Button");
btnsavedisabled = false;
var filepath = "";
var fileupload = documentgetElementById(id);
if (fileuploadvaluelength < ) { alert(请选择文件！); return; }
var agent = windownavigatoruserAgent;
if (documentall) {
var isIE = agentindexOf(MSIE ) != ;
var isIE = agentindexOf(MSIE ) != ;
//IE和IE获得文件路径
if (isIE || isIE) {
fileuploadselect();
filepath = documentselectioncreateRange()text;
}
//IE获得文件路径
else
{ filepath = filevalue; }
//PageMethodsValidateFile(filepath maxsize ieCallBack);
alert(filepath);
}
if (agentindexOf("Firefox") >= ) {
alert("FF");
alert(getValue());
return false;
if (fileuploadfiles) {
var size = fileuploadfiles[]fileSize;
if (size > parseInt(maxsize)) {
  fileuploadparentNodeinnerHTML = <input type="file" name=" +  fileuploadname + " id=" + fileuploadid + "  onchange="disableSave(this);"/> ;
alert("文件超过大小！");
}
else { alert("文件上传成功！"); }
}
}
}
