Abort Ajax Request within class

[mathceleb]

I'm getting a message saying request is undefined. Ajax runs fine, but how do I abort the process?

K12.Header = {

	init: function() {
var runningRequest = false;
var request;

		// init the type ahead boxes
		//K12.initTypeAhead();

$('.txt').keyup(function(e) {
e.preventDefault();

        if(runningRequest){
           request.abort();
        }

runningRequest=true;

main_standard="";
sub_standard="";
standard="";
g="";
grade_level="";
fields = {keyword:$(this).val(),main_standard:main_standard,sub_standard:sub_standard,grade_level:grade_level,archive:0};
var json_vars = {
action:'Search.instant_search',
info:encodeURIComponent(JSON.stringify(fields))
};
	var request=K12.ajax(json_vars, function(data) {
		var res = evalJSON(data);
runningRequest=false;
                // now spit out html items to the screen below
//alert(res.name);
               $('.right-container').html('');
               $('.right-container').html(unescape(data));
                         
											
	});	
						
});

});

I made two changes in bold. However, which allows the program to run, but does not kill the prior request. If I try to put the request.abort() outside of the ajax call, it claims it is not-existing?

K12.Header = {

init: function() {
var runningRequest = false;
var request=null;

// init the type ahead boxes
//K12.initTypeAhead();

$('.txt').keyup(function(e) {
e.preventDefault();

if(runningRequest){
request.abort();
}

runningRequest=true;

main_standard="";
sub_standard="";
standard="";
g="";
grade_level="";
fields = {keyword:$(this).val(),main_standard:main_standard,sub_standard:sub_standard,grade_level:grade_level ,archive:0};
var json_vars = {
action:'Search.instant_search',
info:encodeURIComponent(JSON.stringify(fields))
};
var request=K12.ajax(json_vars, function(data) {
if (request!=null) {request.abort();}
var res = evalJSON(data);
runningRequest=false;
// now spit out html items to the screen below
//alert(res.name);
$('.right-container').html('');
$('.right-container').html(unescape(data));


});

});

});

Solved:

I had to pass this back into K12.header.request
