问题描述
code $>元素如下:
$ bupdateList = function(){var input = document.getElementById ('文件'); var output = document.getElementById('fileList'); output.innerHTML ='< ul>'; for(var i = 0; i< input.files.length; ++ i){output.innerHTML + ='< li> + input.files.item(i).name +'< / li> ; } output.innerHTML + ='< / ul>';} < input type =filename =fileid =filemultiple onchange =javascript:updateList()/>< br />所选文件:< div id =fileList >< / div>
I am using Struts2 to upload multiple files:
<s:file name="files" multiple="multiple" />When I select multiple files it displays the number of files, eg. 3 files.
The project requirements are that the user should be able to see what files he selected before uploading.
Is it possible to display the selected files names in a list or maybe in the control itself ?
解决方案You can use the HTML5 files property of the <input type="file" /> element like follows:
updateList = function() { var input = document.getElementById('file'); var output = document.getElementById('fileList'); output.innerHTML = '<ul>'; for (var i = 0; i < input.files.length; ++i) { output.innerHTML += '<li>' + input.files.item(i).name + '</li>'; } output.innerHTML += '</ul>'; }<input type="file" name="file" id="file" multiple onchange="javascript:updateList()" /> <br/>Selected files: <div id="fileList"></div>这篇关于如何在Struts2中上传多个文件之前显示选定的文件名?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
