handleClick(item) {let fileSrc = `../../../data/${item.filepath}/${item.xzfilename}`;let filename = item.filename;let imgtype = ['png','jpg','jpeg','PNG','JPG','JPEG'];if(imgtype.indexOf(item.filename.split('.')[1]) != -1){debugger;//图片类型下载方式this.saveFileImg(fileSrc,filename);}else{debugger;//文档类型window.location.href = fileSrc;}
},
