ajax中执行服务器返回的js脚本

来源：互联网发布：金和网络财报2017 编辑：程序博客网时间：2024/05/30 05:14

在ajax的回调函数中，先获取js脚本的值，赋值到页面的某一个控件，比如一个div，如：

document.getElementById("uccenter").innerHTML=data.ucString; //赋值给id为uccenter的div

然后获取此div中的script对象，如：

var myDivScript = document.getElementById("uccenter").getElementsByTagName("script").item(0);

再创建一个新的script对象，因为只有新的对象页面才会执行

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

把js脚本的属性值赋值给新的script对象

 newScript.setAttribute("src",myDivScript.getAttribute("src")); newScript.setAttribute("reload",myDivScript.getAttribute("reload")); newScript.innerHTML = myDivScript.innerHTML;

最后，添加心script对象到页面：

document.getElementsByTagName("HEAD").item(0).appendChild(newScript);

// 用户注册完成回调函数001function loginSuccessAjaxCallback(data){if(null == data.resultString || "" == data.resultString){if(null != data.ucString || "" != data.ucString){                 document.getElementById("uccenter").innerHTML=data.ucString;  var myDivScript = document.getElementById("uccenter").getElementsByTagName("script").item(0); var myDivScript2 = document.getElementById("uccenter").getElementsByTagName("script").item(1); var newScript = document.createElement("script"); var newScript2 = document.createElement("script"); newScript.setAttribute("src",myDivScript.getAttribute("src")); newScript.setAttribute("reload",myDivScript.getAttribute("reload")); newScript.innerHTML = myDivScript.innerHTML;  newScript2.setAttribute("src",myDivScript2.getAttribute("src")); newScript2.setAttribute("reload",myDivScript2.getAttribute("reload")); newScript2.innerHTML = myDivScript2.innerHTML; document.getElementsByTagName("HEAD").item(0).appendChild(newScript);  document.getElementsByTagName("HEAD").item(0).appendChild(newScript2); }window.location.reload();}else{$('#loginResuleMessage').html(data.resultString);}}

这里的js脚本形如：

<script type="text/javascript" src="http://localhost/bbs/api/uc.php?time=1388937248&code=ae28TF01utAnYLk0%2BhVarCC0mO8hxTN7K7JoPAHmkHN3sX1OQBv6IExLuUA66n78X%2B8mSnvDpAThuBSOm3ph9NqKHJbn3gMQ5W%2Bmyn%2BbFwYQ8zMaIV5BXhpYzoR0Hx0a6Qa02e0gcNH%2B2ROVk8MF4Ms8CUFeyBMVuBahxbCeaQ" reload="1"></script><script type="text/javascript" src="http://localhost:8080/yxw/api/uc.php?time=1388937248&code=1752B0%2FcsBy%2FZkYV0Hf2cxoxk5tx2IK4CwhYqVRbvuzcqL051vFGWmq5E0vaJw7tIXqDZb%2BEAtgPPNkgten9owDk%2FXu%2B5YRJ8XBT6tjlHery2BtZPNjlUyZKBtamHs6%2FLEUPTciQqB5vuxjW0%2F1ib%2FTqpZL8CweG%2FPkgFiZ41Q" reload="1"></script>
