HTML при загрузке тела запустить ссылку href

У меня есть эта ссылка HTML:

<a href="#" class="big-link" data-reveal-id="myModal">Fade and Pop</a>

который использует jquery, чтобы открыть всплывающее окно.

как я могу сделать поле появляться при загрузке тела?

вот полный код jquery:

(function($) {

/*---------------------------
 Defaults for Reveal
----------------------------*/

/*---------------------------
 Listener for data-reveal-id attributes
----------------------------*/

    $('a[data-reveal-id]').live('click', function(e) {
        e.preventDefault();
        var modalLocation = $(this).attr('data-reveal-id');
        $('#'+modalLocation).reveal($(this).data());
    });

/*---------------------------
 Extend and Execute
----------------------------*/

    $.fn.reveal = function(options) {


        var defaults = {  
            animation: 'fadeAndPop', //fade, fadeAndPop, none
            animationspeed: 300, //how fast animtions are
            closeonbackgroundclick: true, //if you click background will modal close?
            dismissmodalclass: 'close-reveal-modal' //the class of a button or element that will close an open modal
        }; 

        //Extend dem' options
        var options = $.extend({}, defaults, options); 

        return this.each(function() {

/*---------------------------
 Global Variables
----------------------------*/
            var modal = $(this),
                topMeasure  = parseInt(modal.css('top')),
                topOffset = modal.height() + topMeasure,
                locked = false,
                modalBG = $('.reveal-modal-bg');

/*---------------------------
 Create Modal BG
----------------------------*/
            if(modalBG.length == 0) {
                modalBG = $('<div class="reveal-modal-bg" />').insertAfter(modal);
            }           

/*---------------------------

            //Entrance Animations
            modal.bind('reveal:open', function () {
