Question

i need to know if this is possible and how….

I have a series of linkk

< a href=”#” id=”hello” > HELLO < /a >

< a href=”#” id=”welcome” > welcome < /a >

< a href=”#” id=”start” > start < /a >

< a href=”#” id=”finish” > finish < /a >

what i want to do is as i click on the link I wish to add the id value to an array(words). so if i click all the 4 links my array should have hello, welcome,start,finish. Consequently if that is not possible can you concatenate them to a single variable on each click without destroying the previous data in the variable..words=(hello|welcome|start|finish).

any help is appreciated.

thanks
andy

Answer 1

so if your js file looks like this (and jquery has been included on the page)

var ClickedLinks = [];
$(function () {
    $('a').click(function () {
        var id = $(this).attr('id');
        if ($.inArray(id, ClickedLinks) == -1) {
            ClickedLinks.push(id);
        }
    });
});

This will check the array and NOT add it again.

EDIT: Fixed $.inArray returning a position, rather than a boolean (as I incorrectly assumed)
