Hi all,
I have the following code that is really bugging me, I'm thinking perhaps the post() function needs to be blocking. I am new to jQuery(latest version) and AJAX, but I'm using ColdFusion which returns some HTML in the data variable.
var dataResult;
var statusResult;
$.post('fh_result.cfm',$('#myform').serialize(),function(data,status){
dataResult = data;
statusResult = status;
});
//alert(statusResult);
if ('success' == statusResult)
{
alert(statusResult);
$('#result').html(dataResult);
}
When I uncomment out the first alert, it returns 'undefined' but then it goes into the if block and the next alert box it says 'success'. If I comment out that line it doesn't make it into the if statement at all. My guess is that I want to make this a blocking call or something because I want to insert the data on the page after the post. I also have a problem when I re-write the top code as follows:
var dataResult;
var statusResult;
$.post('fh_result.cfm',$('#myform').serialize(),function(data,status){
dataResult = data;
statusResult = status;
alert(statusResult);
$('#result').html(dataResult);
});
//alert(statusResult);
Now in this case, the alert says 'success' when I comment out the second alert box. When I uncomment it out, I get one alert that says success and the other that says undefined, but this time it updates the DOM with the result of the postback as desired. How can I do this without the alert box?
