javascript - dropzone js 链接删除 url 与删除按钮

Question

在 Dropzonejs 中，我正在创建删除按钮，然后将其附加到缩略图，如何使用 addRemoveLinks:true 将我从服务器直接获取的 url 链接到删除按钮，

//Write function if you need to add some event after files added
      myDropzone.on("addedfile", function(file) {
        console.log('Files Added using ---------->'+$attrs.apiCall);
      var _this=this;
        /* Maybe display some more file information on your page */
       var removeButton = Dropzone.createElement("<button data-dz-remove>-Remove file</button>");
        removeButton.addEventListener("click", function(e) {
        e.preventDefault();
        e.stopPropagation();
        _this.removeFile(file);
        });
        file.previewElement.appendChild(removeButton);
      });

您可以添加删除链接..在添加文件事件中，您可以在服务器响应中获取URL并在删除链接中设置它。

 myDropzone.on("addedfile", function (file) {
     var _this = this;

     /* Maybe display some more file information on your page */
        var removeButton = Dropzone.createElement("<button data-dz-remove " +
                        "class='del_thumbnail btn btn-default'><span class='glyphicon glyphicon-trash'></span></button>");

        removeButton.addEventListener("click", function (e) {
        e.preventDefault();
        e.stopPropagation();
        var server_file = $(file.previewTemplate).children('.server_file').text();
        // Do a post request and pass this path and use server-side language to delete the file
        //          $.post(server_file,{'X-CSRFToken': $cookies.csrftoken}, 'json');
        $http({
            method: 'POSt',
            url: server_file,
            headers: {
                   'X-CSRFToken': $cookies.csrftoken
            }
        });
         _this.removeFile(file);
         });
         file.previewElement.appendChild(removeButton);
 });
