如何将URL添加到触发jQuery在加载时运行函数的URL

Question

Is there a way to add a url param like: http://site.com?open=true

And on document ready, if jQuery sees the open param set to true execute a function?

Thanks

first lets make a good Query string searcher in JS

function querySt(qsName, url)
        {
            var theUrl;
            if (url == null || url == undefined)
                theUrl = window.location.search.substring(1); else theUrl = url;
            var g = theUrl.split("&");
            for (var i = 0; i < g.length; i++) {
                var pair = g[i].split("=");
                if (pair[0].toLowerCase() == qsName.toLowerCase())
                {
                    return pair[1];
                }
            }
            return null;
        }



$(function (){
  if (querySt("open")!='true') return;

});

taken from website http://www.onlineaspect.com/2009/06/10/reading-get-variables-with-javascript/

 function $_GET(q,s) { s = s ? s : window.location.search; var re = new RegExp('&'+q+'(?:=([^&]*))?(?=&|$)','i'); return (s=s.replace(/^?/,'&').match(re)) ? (typeof s[1] == 'undefined' ? '' : decodeURIComponent(s[1])) : undefined; }

You can test location.href with a regex:

if (location.href.match(/open=true/)
    // do something

You might want to work on the regex though, to make sure it works for you.
