I am trying to implement a feature where the value of an element decreases each time a different element is clicked. Currently, I have the following code:
$("#trigger_heritage").click(function () {
$(".heritage_content ul").css("margin-left", + -880);
// This will move the .heritage_content ul-element 880px further left every time it's clicked
});
However, the element only moves 880px once and does not increase with each click. How can I achieve this functionality?
If you want to adjust the current value, you can input a string in the form of -=[value] into the css() method. Give this a try:
$("#activate_heritage").click(function () {
$(".heritage_content ul").css("margin-left", '-=880');
});
Take a look at this straightforward demonstration:
$(document).ready(function() {
var position = 0;
$(".left").click(function () {
position -= 25;
$(".move").css("margin-left", position + "px");
});
$(".right").click(function () {
position += 25;
$(".move").css("margin-left", position + "px");
});
})
