This javascript function must be executed when the page loads

What is the best way to trigger this function onLoad for a specific URL?

function fadeLoop() {

    var count = 0,
        elements = $('.fader').hide(),
        duration = 500;

    function displayElement() {
        elements.fadeOut(duration) // hide all elements
            .filter(function(index) {
                return index == count % elements.length;
            }) // determine correct element to show
            .delay(duration) // delay until fadeout is completed
            .fadeIn(duration); // then display it
        count++;
    }; // loop through elements and display correct one
    displayElement(); // show first element    
    return setInterval(function() {
        displayElement(); // show next element
    }, 5 * 1000); // repeat every 5 seconds     };

$(function() {
    var inter;

    $("#start").click(function() {
        if (inter == undefined){
            inter = fadeLoop();
            $(this).val("Stop");
        }
        else{
            clearInterval(inter);
            $(this).val("Start");
            inter = undefined;
        }
    }); });​

This function enables my interactive tooltips, but I am unsure how to call it. Also, should it be placed in the page or the header? The script is on the page while the link is in the header...any suggestions?

Thank you for your help.

Chris

Answer №1

To invoke the function, follow this syntax:

$(document).ready(function(){
fadeLoop()
});


Modify

It appears that the function is triggered by a click event. How about updating the code as follows:

$(document).ready(function(){
       $('#start').trigger('click');
    });

Answer №2

Javascript.

function fadeEffect() {
    ....
});​

$(window).on('load', fadeEffect);

Answer №3

Appreciation to all who contributed. Below is the finalized and functioning code for your enjoyment!

</script>
<script src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
fadeLoop()
function fadeLoop() {

    var counter = 0,
        divs = $('.fader').hide(),
        dur = 300;

    function showDiv() {
        $("div.fader").fadeOut(dur) // conceal all divs
            .filter(function(index) {
                return index == counter % divs.length;
            }) // determine correct div to display
            .delay(dur) // wait until fadeout is complete
            .fadeIn(dur); // then reveal it
        counter++;
    }; // iterate through divs and show correct one
    showDiv(); // display first div    
    return setInterval(function() {
        showDiv(); // show next div
    }, 7 * 1000); // repeat every 5 seconds    
};

$(function() {
    var interval;

    $("#start").click(function() {
        if (interval == undefined){
            interval = fadeLoop();
            $(this).val("Stop");
        }
        else{
            clearInterval(interval);
            $(this).val("Start");
            interval = undefined;
        }
    });
});
});
</script>
