javascript 获取表单file全路径
ie8下通过obj.value方式得到的是X:\fakepath\XXX
<html><head><title>get file input full path</title><script language='javascript'>function getFullPath(obj){if(obj){//ieif (window.navigator.userAgent.indexOf("MSIE")>=1){obj.select();return document.selection.createRange().text;}//firefoxelse if(window.navigator.userAgent.indexOf("Firefox")>=1){if(obj.files){return obj.files.item(0).getAsDataURL();}return obj.value;}return obj.value;}}</script></head><body><input type="file" onchange="document.getElementById('img').src=getFullPath(this);" /><img id="img" /></body></html>
