Bootstrap 文件上传插件File Input的使用

1.jsp代码

<div class="form-group draggable">
			<label class="col-sm-3 control-label">附件：</label>
			<div class="col-sm-9 ">
				<label class="block clearfix"> <span
					class="block input-icon input-icon-right"><input
						id="att_files" name="files" type="file" multiple
						class="file-loading"> </span>
				</label>
				<div id="errorBlock" class="help-block"></div>
				<div style="display: none;">
					<input id="tempnames" type="text" /> <input id="realnames"
						type="text" /> <input id="isupload" type="text" value="0" />
				</div>
			</div>
		</div>

2.js中的代码

//初始化fileinput控件（第一次初始化）
/**
 *@param ctrlName  对应id
 * @param uploadUrl 
 */
function initFileInput(ctrlName, uploadUrl) {
	var filenames = [];
	var control = $('#' + ctrlName);
	control.fileinput(
			{
				language : 'zh', // 设置语言
				uploadUrl : uploadUrl, // 上传的地址
				showUpload : true, // 是否显示上传按钮
				showCaption : true,// 是否显示标题
				showPreview : true,// 是否预览
				uploadAsync : false,// 多文件是否异步上传
				browseClass : "btn btn-primary", // 按钮样式
				elErrorContainer : "#errorBlock",
				slugCallback : function(filename) {
					return filename.replace(',', '_');
				},
				previewSettings : {
					image : {
						width : "150px",
						height : "110px"
					},
					text : {
						width : "150px",
						height : "110px"
					},
					pdf : {
						width : "150px",
						height : "110px"
					},
				},
				fileActionSettings : {
					showUpload : false,
					showZoom : false,
				},
				maxFileSize : 40000000,
				maxFileCount : 10,
				allowedFileTypes : [ 'image', 'html', 'text', 'video', 'audio',
						'flash', 'pdf', 'docx', 'xlsx' ]
			}).on('fileselect', function(event, numFiles, label) {
		if (numFiles > 0) {
			$('#isupload').val(1)
		}
	}).on('filecleared', function(event) {
		$('#isupload').val(0)
	}).on("filebatchuploadsuccess", function(event, data, previewId, index) {
		var backdata = data.response;
		var realnames = data.filenames;
		var tempnames = [];
		for (var i = 0; i < backdata.length; i++) {
			tempnames.push(backdata[i].name);
		}
		$('#isupload').val(0)
		if (ctrlName == 'att_files') {
			$('#tempnames').val(tempnames)
			$('#realnames').val(realnames);
		} else {
			$('#tnames').val(tempnames)
			$('#rnames').val(realnames);
		}

	}).on('filebatchuploadcomplete', function(event, files, extra) {
		$(this).fileinput('disable');
	});

}
