angular7中使用iframe来加载外部页面

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了angular7中使用iframe来加载外部页面相关的知识，希望对你有一定的参考价值。
在angular7中使用echarts的线性地图的时候，发现出来缩成了一团，暂未找到解决方案。但是在普通的html中直接引入并使用是没有问题的。因此，转换了思路，使用iframe来加载外部的html，因为在外部html中是正常的。
将正常的html页面放到angular项目的assets下面，然后在angular组件中通过iframe动态引入。这样就可以正常显示了。数据请求可以单独放到页面中。
静态html页面及目录
html内容：和echarts官网案例一样
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="echarts.min.js" type="text/javascript" charset="utf-8"></script>
<script src="china.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>df
<div id="map" style="width: 1000px; height: 600px; border: 1px solid red;">
</div>
<script src="./axios.min.js"></script>
<script type="text/javascript">
// ajax数据请求，使用的是axios， 也可以通过本地存储进行传递数据
console.log(axios.get('http://api.komavideo.com/news/list').then(data =>
console.log(data);
));
