How to call one jquery method from another?

I am new to jquery. How do I call a jquery function from another function. What am I doing wrong below?

$('#search').bind({

//  focus: function(){ alert('focused');},
    keyup: callAjax开发者_如何学JAVA,      // call CallAjax function
});

function callAjax(){
    $.ajax({
       // perform something here
    });
}

How to call callAjax function on keyup event?

what you want is probably this ?:

     $('#search').keyup(function() {
        callAjax();
     });

or you can try this:

$('#search').bind('keyup', function() {
     callAjax();
});

When the button with ID search is 'on-key-up', this event handler will invoke callAjax..

try with

keyup: function() {
           callAjax();
        }, 

$('#search').bind('keyup', callAjax);

For me all the code works well:

<input type="text" name="search" id="search"/>

<script type="text/javascript">
function callAjax(){ alert('callAjax'); /* call whatever you want here */ }

$(function(){
    $('#search').bind({click: function(){alert('click');}, keyup: callAjax});
});
</script>
