I am working on a commenting system and I was able to get it working by using 5 separate scripts, which are exactly the same, except for having slightly different variables. I had to repeat (copy & paste) the js function 5 times in the html <head>, and only allow for 5 posts per page. Which works fine. But, I thought maybe I could replace it with a single function that includes an iteration counter that changes the variables automatically?
Here's what I have now (below), if you think this can be easily turned into 1 function with iteration counter, please let me know how, as I am new to js. I already have the iteration working on the php end, but, I just couldn't figure out how to do it for the javascript.
<script type="text/javascript">
$(function() {
$(".submit1").click(function() {
var post_id = $("#post_id1").val();
var member_id = $("#member_id").val();
var comment = $("#comment1").val();
var dataString = 'post_id='+ post_id + '&member_id=' + member_id + '&comment=' + comment;
if(comment=='') {
alert('Please enter a valid comment 1');
} else {
$("#flash1").show();
$("#flash1").fadeIn(2400).html('<span class="loading">Loading Comment...</span>');
$.ajax({
type: "POST",
