Checking if the input is valid before invoking a JavaScript/jQuery function

Question

Checking if the input is valid before invoking a JavaScript/jQuery function

I am working on a wizard using TypeScript and ASP.NET which consists of several steps. Here is an example:

Step 1:

TextBox input <---Name TextBox input <--- Age

Button onClick="nextStep()"

When I click on the button, I want to validate my input using jQuery Validation and call the function nextStep() if the validation passes.

The problem is that the form is not structured properly, and nextStep() makes an Ajax request.

Is there a quick solution to this issue?

Apologies for being a beginner in this area.

Answer №1

Consider assigning specific identifiers to your nextStep functions

Here's an example in your HTML template:

<button onClick="nextStep(1)" />

And in your TypeScript file:

nextStep(id: number): void {
   if (id == 1) {
     // Perform validation checks here, return false if not valid
   }

   // Execute necessary actions if validation is successful, such as making AJAX calls
}
