    118. 

  118.             $("#Title").text("编辑资源")
    119. 

  119.             $("#editModal").modal("show");
    120. 

  120.         }
    121. 

  121.     });
    122. 

  122. };
    123. 







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  


        });   


}












 


















接下来 通过ajax向后台请求对应的编辑的图片数据组装数组传入到 上面的方法中  


就可以在页面上显示了  


注：在 ajax中 初始化 fileinput 是配置参数是不起作用的  需要 先销毁，再初始化  


1、销毁fileinput  见官网 http://plugins.krajee.com/file-plugin-methods-demo  


  $("#upload").fileinput('destroy');  


     //初始化方法   


        edit_image();  


相关配置见官网

2、销毁fileinput另外一种是先根据上传控件找到上传控件的父节点，然后删除上传控件节点，然后再重新创建一个上传控件，并添加到父节点中，


html 代码如下：


    

  1. <div class="form-group">
    2. 

  2. <label class="col-sm-2 control-label" for="inputPassword3">选择资源</label>
    3. 

  3. <div class="col-sm-10">
    4. 

  4. <input id="uploadfile" type="file">
    5. 

  5. </div>
    6. 

  6. </div>
    7. 





 


jquery 代码如下：


    

  1.  var divParent = $('#uploadfile').parents('.col-sm-10').empty();
    2. 

  2.     var pwd = $("<input id='uploadfile' type='file'>");
    3. 

  3.     divParent.append(pwd);
    4. 

  4.     var control = $('#uploadfile');
    5. 

  5.     control.fileinput({
    6. 

  6.         'showUpload': true,
    7. 

  7.         'previewFileType': 'any',
    8. 

  8.         language: 'zh',
    9. 

  9.         allowedFileExtensions: ['jpg', 'png', 'jpeg', 'bmp', 'mp4', 'avi', 'mov', 'wmv', '3gp', 'rmvb', 'asf', 'fla', 'swf', 'apk'],
    10. 

  10.         uploadUrl: '/Source/UploadSource',
    11. 

  11.         allowedPreviewTypes: ['image', 'html', 'text', 'video', 'audio', 'flash'],
    12. 

  12.         overwriteInitial: true,
    13. 

  13.         initialPreview: [$("#SourcePath").val(),],
    14. 

  14.         initialPreviewAsData: true, // identify if you are sending preview data only and not the raw markup
    15. 

  15.         //initialPreviewDownloadUrl: 'http://kartik-v.github.io/bootstrap-fileinput-samples/samples/{filename}', // includes the dynamic `filename` tag to be replaced for each config
    16. 

  16.         initialPreviewDownloadUrl: $("#SourcePath").val(),
    17. 

  17.         initialPreviewConfig: [
    18. 

  18.             { caption: $("#SourceName").val(), size: 827000,  "120px", key: 1 },
    19. 

  19.         ],
    20. 

  20.     });
    21.
