单击时将输入值设置为动态变量

Question

I am trying to strip a parameter listingid from the URL, and when onclick it post a value of an input box as the listingid , but i am not able to do so.

Is it possible to do so?

function getpic( name )
{
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( window.location.href );

    if( results == null )
        return null;
    else
        return results[1];
}

var frank_param1 = gup( 'Listingid' );

HTML

<input type="hidden" name="listingid"  onclick="value=list_param">

您可以为此使用Jquery

$('input[name="listingid"]').val(getpic( 'Listingid' ))
