jQuery动态添加script标签

https://blog.csdn.net/weixin_43897661/article/details/89474471

1、

$.getScript(url,success(response,status));

2、

var script = document.createElement(\'script\');

script.type = \'text/jacascript\';

script.src = \'url\';     //填自己的js路径

$(\'body\').append(script);

3、

var script=$(\'<script>alert("I am a script element")<\/script>\');

$(\'body\').append(script);

4、

var script = $(\'<scriptsrc="....."></script>\');   //创建script标签

$(\'body\').append(script);  //将标签插入body尾部

5、

document.write(\'<scriptsrc="\'+realation+\'Js/jquery.cookie.js"></script>\');

document.write(\'<scr\'+\'ipt type="text/javascript" src="./js/dataInfo2.js"></sc\'+\'ript>\');

6、

var script = document.createElement("script");

script.src= "//url.com/jquery.js";

var s = document.getElementsByTagName("script")[0];

s.parentNode.insertBefore(script, s);

7、判断不同的设备调用不同的js

function loadJS(src) {

var script = document.createElement(\'script\');

script.type = \'text/javascript\';

script.src = src;

document.getElementsByTagName(\'body\')[0].appendChild(script);

}

$(function browserRedirect() {

var sUserAgent = navigator.userAgent.toLowerCase();

if (/ipad|iphone|midp|rv:1.2.3.4|ucweb|android|windows ce|windows mobile/.test(sUserAgent)) {

loadJS(\'./js/dataInfo2.js\')

} else {

loadJS(\'./js/dataInfo.js\')

}

})
