在JavaScript中获取查询字符串值
我是编写一个使用Ajax远程保存项目的jQuery函数。我希望能够从我的函数的url中获取 edit.php?id = ###& field = ###
info。我怎么做到这一点?
你不需要jQuery来完成这项任务,你可以简单地用javascript来完成:
function gup(name)
{
name = name.replace(/ [\ [] / ,\\\[)。更换(/[\]]/,\\\]);
var regexS =[\\?&]+ name +=([^&#] *);
var regex = new RegExp(regexS);
var results = regex.exec(window.location.href);
if(results == null)
return;
else
返回结果[1];
}
然后,如果您检索此网址: http://www.yoursite.com/Index.php?g=12¶m=43
来检索'param'参数,所有你需要做的就是:
pre $ var $ param_value = gup('param );
或'g'参数如下:
var param_value = gup('g');
或者用您需要的参数名称切换'param'。

I am writing a jQuery function that saves an item remotely with Ajax. I'd like to be able to grab the edit.php?id=###&field=###
info from the url right in my function. How would I do that?
You don't need jQuery for this task, you can do it simply with javascript :
function gup( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
}
Then if you retrieve this url : http://www.yoursite.com/Index.php?g=12¶m=43 to retrieve the 'param' parameter, all you need to do is this :
var param_value = gup('param');
or the 'g' parameter like this :
var param_value = gup('g');
or switch 'param' with the name of the parameter you need.
