//编辑文件上传 插件初始化    通过封装的方式可以 减少很多重复的代码  

//initialPreviewDownloadUrl: 'http://kartik-v.github.io/bootstrap-fileinput-samples/samples/{filename}', // includes the dynamic `filename` tag to be replaced for each config

initialPreviewDownloadUrl: $("#SourcePath").val(),

initialPreviewConfig: [{ caption: $("#SourceName").val(), size: 827000, width: "120px",url: "/source/delete",key: 1 },], 额外数据上文中的uploadExtraData

下面是参数初始化设置说明

function edit_image(path,con){  

        $("#upload").fileinput({  

             uploadUrl: "upload", //上传到后台处理的方法  

             uploadAsync: false, //设置同步，异步 （同步）  

             language: 'zh', //设置语言  

             overwriteInitial: false, //不覆盖已存在的图片  

            //下面几个就是初始化预览图片的配置      

             initialPreviewAsData: true,  

             initialPreviewFileType: 'image',  

             initialPreview:path , //要显示的图片的路径  

             initialPreviewConfig:con  

        });
