Issue with JQuery Promise: fail() being invoked before promise resolution

In my TypeScript code, I encountered a peculiar issue with a jQuery promise. The fail() function is being executed immediately, logging an error message to the console, despite the promise resolving successfully afterwards. Here is the code snippet:

            this.jQuery.getJSON(this.options.searchUrl, queryFilter)
                       .done(this.orderLinesCallback)
                       .fail(console.log("Error on retrieving orders"));

Answer №1

success and failure must be defined as functions:

.success(this.handleSuccess)
.failure(function(a, b, c) {
    console.log("An error occurred");
});

By structuring the code in this way, the message

console.log("An error occurred");
will only be displayed when the anonymous function (passed as an argument to failure) is invoked.
