如何在AJAX中以不同方式处理从PHP发送的响应

Question

I am trying to figure out that how can I handle different responses sent from PHP to AJAX differently (I am using toastr for nice message display on front end). Say someone tried to insert some value into the database and the value got inserted successfully, then i sent I message from PHP by

echo "Data inserted";

and this gets caught by ajax response and gets handled by

success: function(response) {
 toastr.success(response);
}

But I want that, when PHP sends a message something like

echo "Unable to insert data";

My AJAX handles it as an error and I want to use toastr.danger() instead of toastr.success().

How can I handle this situation ?

As Jon Stirling said in comment, check HTTP status code (200: OK, 404: Not found, 500: Server error...), statusCode in $.ajax options.

Or use error in $.ajax options (opposed to success options).

Or (but not the best really), check for a word in your response with String.indexOf('yourWord')
