问题描述

如何获得ASP文件上传的JavaScript中的价值。我尝试，但难道不能够得到两个文件上传的价值。

 函数alertupload（）{＆GT;
             VAR firstvalue = document.getElementById(\"ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataList_ctl00_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile\").value;             VAR backvalue = document.getElementById(\"ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataList_ctl01_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile\").value;            警报（frontvalue）;
            警报（backvalue）; }

解决方案

如果<$c$c>ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataLi‌st_ctl00_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile该ID那么它应该工作。

其他明智地使用客户端编号

  VAR firstvalue =的document.getElementById（＆LT;％= uxUploadFile.ClientID％GT;）;
警报（firstvalue）;

How to get the value of asp fileupload in javascript. I tried but wouldnt able to get the value of two file uploads.

function alertupload() {>  
             var firstvalue = document.getElementById("ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataList_ctl00_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile").value;

             var backvalue = document.getElementById("ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataList_ctl01_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile").value;

            alert(frontvalue);
            alert(backvalue);              

 }

解决方案

If ctl01_uxPlaceHolder_uxProductFormView_ctl01_uxOptionGroupDetails_uxOptionDataLi‌st_ctl00_uxOptionItemDetails_uxOptionUploadItem_uxUploadFile the id then it should work.

Other wise use client Id

var firstvalue = document.getElementById("<%= uxUploadFile.ClientID %>");
alert(firstvalue);
