$.post variable as array with values?

sending some data via post but want to send an array to but keep getting errors?

excludes is the array i'm trying to send.

        $.post("/youradmin_v2/scripts/php/process.php", { 
            funcName:'searchContent',
            table:'content', 
            fields:'title,contentID', 
            keyword:$(this).val(), 
            tag:'option',
         开发者_StackOverflow社区   excludes: ['contentType'=>'client','contentType'=>'mainsetion']                 
            }, 
            function(data){
            $("#filterContentMenu").html(data);
        });

I can't seem to find the correct way to format the array for posting?

or to clarify what i want is to turn this into a php array like

$excludes=array('fieldA'=>'client','feildB'=>'mainsetion')   

to be used like

foreach($excludes as $value) {
        $toExclude .=" AND ".$value['name']."!='".$value['value']."' ".$value;
    }

    $.post("/youradmin_v2/scripts/php/process.php", { 
         funcName:'searchContent',
         table:'content', 
         fields:'title,contentID', 
         keyword:'blah', 
         tag:'option',
         excludes: {contentType:'client',anotherContentType:'mainsetion'}              
        }, 
        function(data){
        $("#filterContentMenu").html(data);
    });

You seem to be using PHP-style notation to specify the array keys. Try

excludes: {'contentType':['client','mainsetion']}
