1 问题描述
点击button按钮,提交页面的form表单,后台执行完毕后返回参数,前台页面需要该参数实现跳转,如何实现保留该原来的页面,并在浏览器选项卡新建一个页面,且不被浏览器拦截?
2 方法及问题
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
1)window.open()
在ajax的回调函数中调用window.open()实现会被浏览器拦截。
2)js模拟点击按钮事件
代码如下:
<html lang="utf-8">
<head>
<meta http-equiv="Content-type" Content ="text/html;"charset = "utf-8" >
</head>
<body>
<a id="alink" href="test" target="_blank" style="display: none"><span id="spanlink">test</span></a>
<input type="hidden" id="hdn_val" value="#">
<button type="button" onclick="submit()">打开新页面</button>
<script>
function new_window() {
while(1){
var o_a = document.getElementById('hdn_val');
var val=o_a.value;
if(val!="#"){
var a = document.getElementById('alink');
a.href=val;
var a = document.getElementById('spanlink');
a.click();
break;
}
}
}
function ajax_submit_cb(data){
var a = document.getElementById('hdn_val');
a.value=data;
}
function ajax_submit(){
//模拟ajax有延时,与实际仍有差别,浏览器会检测回调对象,判断是否是鼠标实际点击的按钮
var url='http://www.cnblogs.com/xiaopanlyu/';
setTimeout(ajax_submit_cb(url),3000);
}
function submit(){
ajax_submit();//该函数执行业务逻辑
new_window();
}
</script>
</body>

3 总结
在实际ajax中执行时,必须保持点击按钮的时候 执行新页面的函数new_window 与 ajax函数是同步的,不能将new_window 放在ajax的结果中执行,否则新页面窗口就会被浏览器拦截。
