I'm using this code to submit a form to a php script:
var valid = 'true';
$(document).ready(function(){
$("#contact").submit(function(){
$.post("process.php",
$("#contact").serialize(),
function(data){
if(data.email_check == 'invalid'){
valid = 'false'; //<---not set!
$("#email1").addClass('missing');
$("#message_ajax")
.html("<div class='errorMessage'>Sorry is NOT a valid e-mail address. Try again.</div>");
} else {
$("#message_ajax")
.html("<div class='errorMessage'>YES! this is A valid e-mail address. DO NOT Try again.</div>");
}
}, "json"
);
if(valid == 'true'){
$("#contact").hide();
}
return false;
});
});
I know the script is returning the 'invalid' value because the div and css are updated as expected, but the 'valid' variable never gets set to 'false'. Thinking it was a scope issue I have moved the declaration and if statement around with no joy.
Possible related problem - I'm using firebug to step through the code, but it only stops at my breakpoint the first time the code is executed, and never again, but I can submit the form any number of times and it always responds as expected - valid or invalid. As you can see, I'm very new to jQuery.
You're mixing synchronous and asynchronous code here.
if(valid == 'true'){
$("#contact").hide();
}
return false;
This code ^^^ runs before the callback function(data)
is ever called.
Basically what's happening is this:
