使 iframe 的高度和宽度的自动调整大小
被引用的 iframe 页面，需要引入该文件：
https://raw.githubusercontent.com/davidjbradshaw/iframe-resizer/master/js/iframeResizer.contentWindow.min.js
引用方使用：
import IframeResizer from 'iframe-resizer-react'
<IframeResizer
log
src="http://anotherdomain.com/iframe.html"
style={{ width: '1px', minWidth: '100%'}}
/>
高度控制，根据 heightCalculationMethod 字段判断：
- bodyOffset uses document.body.offsetHeight
- bodyScroll uses document.body.scrollHeight
- documentElementOffset uses document.documentElement.offsetHeight
- documentElementScroll uses document.documentElement.scrollHeight
- max takes the largest value of the main four options
- min takes the smallest value of the main four options
- lowestElement Loops though every element in the the DOM and finds the lowest bottom point †
- taggedElement Finds the bottom of the lowest element with a attributedata-iframe-height

<IframeResizer
src="http://anotherdomain.com/iframe.html"
style={{ width: '1px', minWidth: '100%'}}
heightCalculationMethod="lowestElement"
/>
如果以上判断还是无效，可以通过被引用的 iframe 页面，设置 iframe 的参数：
<script>
let dom = document.querySelector('.test')
window.iFrameResizer = {
heightCalculationMethod: function(){
return dom.offsetHeight
}
}
</script>
<script src="js/iframeresizer.contentwindow.js"></script>
