jQuery ajax returns
- by Tom
I think this will be some obvious problem, but I cannot figure it out. I hope someone can help me.
So I have a slider with 3 slides - Intro, Question, Submit
Now I want to make sure that if the question is answered wrong people cannot slide to Submit.
The function to move slide is like this:
function changeSlide(slide){
// In case current slide is question check the answer
if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){
checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val());
}
jQuery('.modalSteps li.current',base).fadeOut('fast',function(){
jQuery(this).removeClass('current');
jQuery(slide).fadeIn('fast',function(){
jQuery(slide).addClass('current');
});
});
// In case the new slide is question, load the question
if (jQuery(slide).hasClass('questionStep')){
var country = jQuery('input[name="country"]:checked',base).val();
loadQuestion(country);
}
}
Now as you can see on first lines, I am calling function checkAnswer, which takes id of question and id of answer and pass it to the AJAX call.
function checkAnswer(question, answer){
jQuery.ajax({
url: window.base_url+'ajax/check_answer/'+question+'/'+answer+'/',
success: function(data){
if (!data.success){
jQuery('.question',base).html(data.message);
}
}
});
}
The problem i am having is that I cannot say
if(checkAnswer(...)){}
Because of Ajax it always returns false or undefined. What I need is something like this:
function changeSlide(slide){
// In case current slide is question check the answer
if (jQuery('.modalSteps li.current',base).hasClass('questionStep')){
if (!checkAnswer(jQuery('input[name="question_id"]',base).val(), jQuery('input[name="answer"]:checked',base).val())){
return false;
}
}
...
So it will prevent the slide from moving on.
Now when Im thinking about it, I will probably have slide like "Wrong answer" so I could just move the slide there, but I would like to see the first solution anyway.
Thank you for tips
