jquery: If statement not working inside ajax success function

Question

I have a success function in my AJAX which returns the response text from a python script which can be either \"SUCCESS\" or \"EMPTY\". Now I want to place an if-loop insid

Answer 1

This means that what you're responding with isn't "SUCCESS". It probably has a line break or other whitespace before or after it, maybe more than one.

Perhaps:

if (/^\s*SUCCESS\s*$/.test(data)) {
    // Success
}

Or use jQuery's $.trim:

if ($.trim(data) === "SUCCESS") {
    // Success
}

Also be sure that you're not replying with "Success" or "success", as string comparisons are case-sensitive.

If you're not sure:

if (/^\s*SUCCESS\s*$/i.test(data)) {
    // Success
}

or

if ($.trim(data).toUpperCase() === "SUCCESS") {
    // Success
}

Answer 2

check if you don't have any additional spaces before/after "SUCCESS"

And also try to change

if(data === "SUCCESS"){

to

if(data == "SUCCESS"){

Answer 3

submitHandler: function (form) {

            $.ajax({
                type: 'post',
                url: '/cgi-bin/getdataworld.py',
                data: $(form).serialize(),

                success: function(data1) {
                        //document.write(result);
                        console.log("result is "+data1);
                        alert(data1);

                        if(data1 == "SUCCESS"){
                        window.location = 'index.html';
                           }
                       else{
                             alert("NO DATA PRESENT");
                           }


                },

                error: function (responseData) {
            console.log('Ajax rariequest not recieved!');
        }

            });

            return false;
        }

try this here two things i noticed one is === in if statement and other you are using data as variable some time its conflicts in some browser
