HTML 单击a标签 实现下载文件而不是浏览器打开预览

 

 

1. <a d ownload class="down" title="">  

2. function download(src,name) {
   // 创建隐藏的可下载链接
   var eleLink = document.createElement('a');
   eleLink.href = src;
   eleLink.download = name;
   eleLink.style.display = 'none';
   eleLink.href = src;
   document.body.appendChild(eleLink);
   eleLink.click();
   document.body.removeChild(eleLink);
   }

3. //js下载文件

4. case 'show':
   var urls = data.fileurl;

   var three = urls.split(".");
   var last = '.' + three[three.length - 1];
   last = last.toLowerCase();
   if (last == ".pdf") {
   common.CreateAddForm('查看', urls, {
   width: '100%',
   height: '100%'
   });
   } else {
   download(urls, data.filename);
   }
   break;

 

 

/*
