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
}
