在继续之前,请确认所有图像都已加载到`$(window).load()`函数中

试试这个:

// get the total number of images inserted in the DOM
var imgCount = $('#slideshow img').length;

// initialize a counter which increments whenever an image finishes loading
var loadCounter = 0;

// bind to the images' load event
$("#slideshow li img").load(function() {

    // increment the load counter
    loadCounter++;

    // once the load counter equals the total number of images
    // set off the fancy stuff
    if(loadCounter == imgCount) {
        slide_interval = setInterval( "slideSwitch()", slide_duration );
    }
}).each(function() {

    // trigger the load event in case the image has been cached by the browser
    if(this.complete) $(this).trigger('load');
});
