Jquery 单击按钮时暂时暂停功能
我一直在想如何做到这一点,但实际上没有取得任何进展。我需要在单击按钮时暂停下面的功能,并在第二次单击时再次启动它Jquery 单击按钮时暂时暂停功能,jquery,settimeout,Jquery,Settimeout,我一直在想如何做到这一点,但实际上没有取得任何进展。我需要在单击按钮时暂停下面的功能,并在第二次单击时再次启动它 var About = function(dom) { this.text_spans = $('li', dom); this.len = this.text_spans.length; this.index = 0; this.init(); } $.extend(About.prototype, { interval: 2.5 *

that.text_spans.eq(that.index % that.len).addClass('visible');
setTimeout(arguments.callee, that.interval);
}, that.interval);
}
});
此函数的目标是隐藏一系列文本(例如,在li
中)并无限循环。单击按钮/链接时,功能将暂停并停止更改文本
我知道这与setTimeout()
和clearTimeout()有关,但我并不真正理解让它工作的语法或方法。有人能帮我理解吗?非常感谢:)试试这样的方法():

请您在JSFIDLE上分享一个演示,这样我们可以更容易地帮助您:)当然,对不起,我忘了。以下是链接:
$.extend(About.prototype, {
interval: 2.5 * 1000,
init: function () {
var that = this;
$('a.toggle').click(function(){
var running = $(this).hasClass('running');
$(this).toggleClass('running', !running);
if (running){
clearInterval(that.timer);
} else {
that.timer = setInterval(function () {
that.text_spans.eq(that.index++ % that.len).removeClass('visible');
that.text_spans.eq(that.index % that.len).addClass('visible');
}, that.interval);
}
}).click(); // start timer
}
});
