Im trying to create separate .clicks() like -> $('.blue').click(function(){}); not only one function for all of them. any help would be appreciate it
Here is my code:
<?php
echo "Welcome, ".$_SESSION['username'].".<br/> ";
echo "My name is: ".$_SESSION['fname']." ";
?>
<br/>
<br/>

Red
Green
<form action='' method='POST'>
<br/><input type='submit' name='logout' value='Logout'/>
</form>
<div id="show"></div>
<script>
function Swap(color){
var url = "php/test.php";
$.post(url, {ColorVar: color}, function(data){
$("#show").html(data).show();
});
location.reload(true);
}
</script>

Try this, hope it will help
<a href="javascript:void(0)" class="change-color" data-color="blue"/>Blue</a>
<a href="javascript:void(0)" class="change-color" data-color="red"/>Red</a>
<a href="javascript:void(0)" class="change-color" data-color="green"/>Green</a>
<script>
var url = "php/test.php";
$( document ).ready(function() {
$(document).on('mousedown', '.change-color', function(){
var color = $(this).attr('data-color');
$.post(url, {ColorVar: color}, function(data){
$("#show").html(data).show();
});
location.reload(true);
})
});
</script>

THanks #user3795381 your answer helped me point myself into the right direction.
This is what I was looking for.
<script>
var url = "php/test.php";
$(document).ready(function() {
$(".change").click(function(){
var color = $(this).attr('data-color');
$.post(url, {ColorVar: color}, function(data){
$("#show").html(data).show();
});
location.reload(true);
})
});
</script>

I could give you some tips:
You can use a single class for all links which save something to your database. For example 'do-save-color'.
You can store the data you want your to save as data-* attributes. You can name those to whatever you want but they have to start with data-. For example data-save-color="blue".
Save blue!
Use a global observer which 'captures' clicks on those links
$(document).on('click', '.do-save-color', function () {
// Your saving logic here
});
In your function use jQuery to read the data attribute and then post it:
var $link = $(this),
color = $link.data('save-color'); // color is now: "blue"
// Your AJAX logic here
Does this help you?
PS: Why do a location.reload() when you are saving things using AJAX?

here is a example with some html-classes (js-*) for js ...
html:
Blue
Red
Green
<p id="js-show" class="some-text">lall</p>
js:
$(".js-switch-style").click(function() {
$.post("/", { color: $(this).data("color") }, function(data) {
$("#js-show").html(data).show();
});
});
