Calling JavaScript variable in separate JQuery function

Question

I am trying to use the value of a variable I define using JavaScript for a JQuery function. All of this happens in one .html file. In the body, I create this script:

<script type="text/javascript">
var clicks = 1;
function onClick() {
    //Code here to change value of 'clicks'
};
</script>

Later in that file, I use JQuery to pull data from a server when a button called 'previous' is clicked. I use this code:

$('#previous').click(function(){
    $('#question').load('/php/getQuestion.php',
      { name: $("clicks").val()} ); //This line is wrong
}

How can I insert the value of 'clicks' into the 'name' field? Thanks

Need HTML, because it isn't obvious what "clicks" actually is supposed to be. 1. If a selector is wrapped in quotes $("tag") it's a <tag>, 2. if a selector is wrapped in quotes and is prtefixed with a period: $(".class") 3. If a selector is wrapped in quotes and is prefixed with a hashmark: $('#id'). $("clicks") means: *find any <clicks> elements. Of course that element doesn't even exist has the root of your problem. — zer00ne

If both of those blocks are within scope, then you have the real number 1 as a jQuery object which is invalid I think you'll get a type error... — zer00ne

clicks is a global variable, so you can use it directly:

$('#previous').click(function(){
    $('#question').load('/php/getQuestion.php',
      { name: clicks} );
}

$("clicks") is looking for a form control element <clicks></clicks> that clearly doesn't exist and certainly wouldn't have a value.

You simply need to use the variable:

 $('#question').load('/php/getQuestion.php', { name: clicks} );
