需求描述

接到的原始需求是这样的，有一个H5页面，页面中有个“点击下载”的按钮，点击之后，完成下载特定的apk。

大概是下面这样的?：

需求分析

接到需求的时候我偷乐了一下，这个H5页面较大的优点是不在微信中使用（微信好坑，各种限制，基本上从微信浏览器里面实现直接下载apk是不太可能的），如果是在平常的浏览器的话，就简单多了。

功能实现

于是我想到了第一种，点击下载按钮的时候改变location.href。

方法一：

// 我随便找了个apk的下载链接举个例子
window.location.href = 'http://imtt.dd.qq.com/16891/26747DD8B125A8479AD0C9D22CA47BC9.apk?fsname=com.snda.wifilocating_4.2.91_3211.apk&csr=1bbd';

拿在浏览器里面试了下，多个安卓机型都可以走通，然后我美滋滋得交付了任务，收拾收拾东西回家。

然后…………

截图中所说的空白页是因为我改变href为apk的下载链接，网页打开的时候会停留在一个空白页，然后一般手机的状态栏上会出现下载apk的进度条。

既然不想出现空白页面的话，那不直接打开一个页面而改成在当前页打开就可以了。

这时候想到iframe，借助iframe可以在原页面打开一个页面。

方法二：

关键代码：

var src = 'http://imtt.dd.qq.com/16891/26747DD8B125A8479AD0C9D22CA47BC9.apk?fsname=com.snda.wifilocating_4.2.91_3211.apk&csr=1bbd';
var iframe = document.createElement('iframe');
iframe.style.display = 'none';
iframe.src = "javascript: '
