Ajax - jQuery和Ajax错误/无效

I am building a webpage that contains a div which holds some data retrieved from a MySql database through PHP. This div shows some products and on its left there is a simple nav bar with different categories. What I am attempting to do is that when the user clicks a category of this nav bar, the content of the div will change, showing the products of that category all of which are stored in the db. So I tried using Ajax (my first time btw), and I can't seem to make it work. My project structure is something like this:

Parent directory

  • php > index.php
  • css > index.css
  • js > index.js
  • img > images here
  • ajax> products-ajax.js / products-ajax.php

The index.php file is linked to both index.js AND products-ajax.js However, I have already tried including the Ajax line of code in both index.js and index.php but I can't make it recieve data back from products-ajax.php Any help is appreciated.

And here's what my test code looks like:

/* THIS IS THE products-ajax.js */

    $('.products-list li').click(function(){

               {p: "Product name"},
               success: function(data){alert(data)}

/* THIS IS THE products-ajax.php */

$p = $_POST['p'];

echo $p;


I realized my broswer's debugger says there's a missing parentheses:

$('.products-list li').click(function(){
 //The debugger says HERE v should go a parentheses
$.post("products-ajax.php", {p: "Product name"}, success: function(data{alert(data)});
