记录：wkwebview加载某些h5界面放大问题

js注入问题，删除就可以了
//适应屏幕
var meta = document.createElement('meta'); meta.setAttribute('name', 'viewport'); meta.setAttribute('content', 'width=device-width'); document.getElementsByTagName('head')[0].appendChild(meta);
// 禁止放大缩小
var script = document.createElement('meta');"
"script.name = 'viewport';"
"script.content="width=device-width, initial-scale=1.0,maximum-scale=1.0, minimum-scale=1.0, user-scalable=no";"
"document.getElementsByTagName('head')[0].appendChild(script);
