In my programming archiveI have this function:
function querystring(key) {
var re=new RegExp('(?:\?|&)'+key+'=(.*?)(?=&|$)','gi');
var r=[], m;
while ((m=re.exec(document.location.search)) != null) r.push(m[1]);
return r;
}

Use the function listed in the answerto this question:
function getParameterByName( 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 decodeURIComponent(results[1].replace(/\+/g, " "));
}
And then just do something like this:
然后做这样的事情：
var qParam = getParameterByName('q');
$('#mytextbox').val(qParam);
