原生js常用

1）获取id

document.getElementById('iframeDiv')

2）获取class

document.getElementsByClassName('iframeDiv')

var iframeDiv = document.getElementsByClassName('iframeDiv')
for (let i = 0; i < iframeDiv.length; i++) {
	console.log(iframeDiv[i])
} 

3）设置style

dom.setAttribute('style', 'width:50%;height:50%')

4）页面跳转

 window.location.href = "http://localhost:9528/#/login?server=" + host

5）获取连接？后的参数

http://localhost:9528/#/login?server=www.jy-sh.com

console.log(getParams('server')) // www.jy-sh.com

function getParams(name) {
  var search = window.location.search.substring(1)
  if (!search) {
    search = window.location.hash.split('?')[1]
  }
  if (search) {
    var obj = JSON.parse('{"' + decodeURIComponent(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g, '":"') + '"}')
    return name ? obj[name] : obj
  }
}

6）settimeout

setTimeout(() => {
 document.getElementById('iframe').setAttribute('style', 'width:400px;height:600px')
}, 10000);
