jquery - 使 jquery 函数在页面加载时运行

Question

我有一个 jquery 函数来更改鼠标悬停时图像的不透明度以产生脉动效果，但我想更改它，以便页面加载后图像立即脉动，从而删除鼠标悬停元素鼠标悬停的效果然后鼠标移出。

这是我的代码

    (function($) {
        $(document).ready(function() {
            window.pulse_image = null;
            window.pulse_continue_loop = false;

            $('.pulse_image').mouseover(function() {
            // User is hovering over the image.
            window.pulse_continue_loop = true;
            window.pulse_image = $(this);

            PulseAnimation(); // start the loop
        }).mouseout(function() {
            window.pulse_continue_loop = false;
            window.pulse_image.stop();
            window.pulse_image.css('opacity',1);
        });
    });
})(jQuery);


function PulseAnimation()
{
    var minOpacity = .33;
    var fadeOutDuration = 650;
    var fadeInDuration = 650;

    window.pulse_image.animate({
        opacity: minOpacity
    }, fadeOutDuration, function() {
        window.pulse_image.animate({
            opacity: 1
        }, fadeInDuration, function() {
            if(window.pulse_continue_loop) {
                PulseAnimation();
            }
        })
    });
}
