how to access parent window javascript variable inside child window(pop-up)?
提问by emilly
I have html page which has global javascript variable with name custName="scott". I open the pop-up window with window.open.
我有一个 html 页面，其中包含 name 的全局 javascript 变量custName="scott"。我用window.open.打开弹出窗口。
Now if I access the custNameinside pop-up window with window.opener.custName, I get values as undefined. How do I access parent window javascript variable inside child window(pop-up)?
现在，如果我使用 访问custName内部弹出窗口window.opener.custName，我会得到值为undefined。如何在子窗口（弹出窗口）中访问父窗口 javascript 变量？

Try this to get the Query string in javaScript
试试这个来获取 javaScript 中的查询字符串
link.html?page=1
<script type="text/javascript">
$.getUrlVar('page');
$.extend({
getUrlVars: function(){
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
},
getUrlVar: function(name){
return $.getUrlVars()[name];
}
});
</script>
