HTML无刷新下载文件方法总汇_html/css_WEB-ITnose

时间：2021-07-01 10:21:17 帮助过：19人阅读

首先要保证有一个后台可以下载文件的方法，这里只总结前端解决方法，所以不对后台做分析，假设现在有一个下载文件的方法/project/download.action。如果不想通过后台直接下载可以看我的另一篇文章《 html使用a标签不通过后台实现直接下载》。

使用a标签

点击下载

这里target属性不给也可以，但是页面会闪一下，体验不好。

使用location.href属性

javascriptfunction downloadFile(url){    location.href=url;}

使用window.open

javascriptfunction downloadFile(url){    window.open(url);}

使用iframe

javascript//javascript版本function downloadFile(url){        var iframe = document.createElement("iframe");          document.body.appendChild(iframe);          iframe.src =url;}//jQuery版本function downloadFile(url){    $("body").append($("").attr("src",url);}</script></pre> <p>调用<br />点击下载</p> </li>  <p>个人推荐第4种方法，比较灵活。                    </div>
