Question

I want to run MySQL query’s on command without reloading the page. I think JavaScript can do this but i am unsure how. What i want to do is have a form with an return id field and when you fill out the form once with the return id and come back later and use that return id and it fills in in a lot of the content for them to save time.

Answer 1

Javascript cannot run MySQL Queries itself; however, you can use ajax to make a call to the server to retrieve the data. I like to use jQuery’s ajax() for my ajax needs.

Here is an example of how jquery’s ajax() method works:

$.ajax({
  url: "pathToServerFile",
  type: "POST",
  data: yourParams,
  dataType: "json"
});
