Question

I did ajax call and got response in callback function like below:

var v="";
....
jq.post(contextPath + "/dmp/workspace/inlineCssExtraction", {
        jsonForSaveInlineCss: JSON.stringify(styleArr)
    }, function(data) {
v=data;
});

return v;

Problem I am facing is, I am getting empty value of v.
I think reason is, ajax response is taken long time and before this retun v; line is executed. Is there any way to resolve this issue?

Regards

You cannot do it this way …. AJAX is asynchronous – the return expression will get executed before the callback function

jq.post(contextPath + "/dmp/workspace/inlineCssExtraction", {
        jsonForSaveInlineCss: JSON.stringify(styleArr)
    }, function(data) {
       processdata(data);
});

You could pass the data to a function which would be called on AJAX success
