JS 事件退出循环
所以我对我的 JS 有点生疏,但这是我的代码...... 基本上我有一个图像,当鼠标悬停时,它会循环显示一个充满其他图像的隐藏 div...淡出它,替换 src,然后淡入。它效果很好。但是一旦它遍历完所有图像,我希望它重新开始并继续循环遍历它们,直到 mouseout 事件停止它。
我以为我可以从函数 cycle_images($(current_image));
中再次调用该函数,但这会导致浏览器崩溃,这是可以理解的。什么是完成此任务的好方法?
$.fn.image_cycler = function(options){
// default configuration properties
var defaults = {
fade_delay: 150,
image_duration: 1500,
repeatCycle: true,
};
var options = $.extend(defaults, options);
this.each(function(){
var product = $(this);
var image = $('div.image>a.product_link>img', product);
var description = $('div.image>div.description', product);
var all_images = $('div.all_images', product);
var next_image = ($(all_images).find('img[src="' + $(image).attr('src') + '"]').next('img').attr('src')) ? $(all_images).find('img[src="' + $(image).attr('src') + '"]').next('img') : $(all_images).children('img').first();;
// mouseover
image.fadeOut(options.fade_delay, function(){
image.attr('src', next_image.attr('src'));
image.fadeIn(options.fade_delay);
});
if (options.repeatCycle){
var loop = function() {
product.image_cycler();
}
setTimeout(loop,options.image_duration);
}
});
};
$(document).ready(function() {
$('div.product').hover(function(){
$(this).image_cycler();
}, function(){
$(this).image_cycler({repeatCycle: false});
});
});
so im a little rusty with my JS, but here is my code...
basically i have an image, that on mouseover, it cycles through a hidden div full of other images... fading it out, replacing the src, and fading back in. it works great. but once it gets through all the images, i want it to start back over and keep looping through them until the mouseout event stops it.
i thought i could just call the function again from within the function cycle_images($(current_image));
, but that leads to the browser freaking out, understandably. what is a good method to accomplish this?
$.fn.image_cycler = function(options){
// default configuration properties
var defaults = {
fade_delay: 150,
image_duration: 1500,
repeatCycle: true,
};
var options = $.extend(defaults, options);
this.each(function(){
var product = $(this);
var image = $('div.image>a.product_link>img', product);
var description = $('div.image>div.description', product);
var all_images = $('div.all_images', product);
var next_image = ($(all_images).find('img[src="' + $(image).attr('src') + '"]').next('img').attr('src')) ? $(all_images).find('img[src="' + $(image).attr('src') + '"]').next('img') : $(all_images).children('img').first();;
// mouseover
image.fadeOut(options.fade_delay, function(){
image.attr('src', next_image.attr('src'));
image.fadeIn(options.fade_delay);
});
if (options.repeatCycle){
var loop = function() {
product.image_cycler();
}
setTimeout(loop,options.image_duration);
}
});
};
$(document).ready(function() {
$('div.product').hover(function(){
$(this).image_cycler();
}, function(){
$(this).image_cycler({repeatCycle: false});
});
});

听起来您希望它在鼠标移开时重新循环并停止。
定义cycle_images()函数后,添加一个标志,repeatCycle,
在cycle_images函数的末尾,添加一个带超时的递归调用,
然后在mouseout中,
It sounds like you want it to re-cycle and stop on mouseout.
After you define the cycle_images() function, add a flag, repeatCycle
At the end of the cycle_images function, add a recursive call with a timeout
Then in mouseout,
