jQuery $.post with passed variables fails

I am wondering why:

$.post("remote.php",
    {'f':a_searchtype, 'partial':value},
    function(data){
        $("#result").html(data);
});

worksfine. but using a variable such as:

ajax_arg = {'f':a_searchtype, 'partial':value};
$.post("remote.php",
    ajax_arg,
    function(data){
        $("#result").html(data);
}); 


causes javascript errors in unrelated sections of code.

The second version can be used in a com开发者_运维百科mon routine that doesn't know what is being passed.

ajax_arg needs to be global varible so add a var infront of it.

ANSWER var ajax_arg = {'f':a_searchtype, 'partial':value};

Hope it helps

Maybe the variable name 'ajax_arg' is also used some where else? 'ajax_arg' is a global variable.
