有没有一种方法可以防止在 iOS 移动版 Safari 上针对下面显示的点击事件发生双击链接问题？
var self = this;
this.$thumbnail.on('click', function(e) {
e.preventDefault();
src = src + '&autoplay=1';
$innerContainer.addClass('yt-hd-thumbnail-clicked');
self.$elem.attr({
'src': src
});
});
我主要是在寻找 JQuery 解决方案。
更新:添加了完整的代码段示例
我提供了一个片段，展示了如何通过 iOS Safari 点击事件两次才能自动播放嵌入的视频:
我已经根据最近的回答对我的原始脚本进行了修改，但仍然无法解决双击问题。
见下文:
(function($, window, document, undefined) {
"use strict";
var defaults = {
darkenThumbnail: false
};
function YouTubeHDThumbnail(element, options) {
this.elem = element;
this.$elem = $(element);
this.settings = $.extend({}, defaults, options);
this._defaults = defaults;
this._name = "youTubeHDThumbnail";
this.init();
}
$.extend(YouTubeHDThumbnail.prototype, {
init: function() {
(this.videoId = null), (this.$thumbnail = null);
// retrieve HD thumbnail
var src = this.$elem.attr("src"),
srcSplit = src.split("?"),
srcMain = null,
srcPure = null;
if (srcSplit.length > 0) {
srcMain = srcSplit[0];
srcPure = srcMain.split("/");
this.videoId = srcPure.pop();
this.$thumbnail = $("<a />")
.attr({
href: "#"
})
.addClass("yt-hd-thumbnail");
let thumb = $("<img/>", {
src: "http://i.ytimg.com/vi/" + this.videoId + "/maxresdefault.jpg"
});
thumb.on("load", () => {
const src =
thumb[0].width < 121 ?
"http://i.ytimg.com/vi/" + this.videoId + "/hqdefault.jpg" :
"http://i.ytimg.com/vi/" + this.videoId + "/maxresdefault.jpg";
this.$thumbnail.append(
$("<img/>", {
src
})
);
});
} else {
console.log("The src attribute of iframe is not valid.");
return;
}
// create container
var $outerContainer = $("<div />")
.addClass("yt-hd-thumbnail-outer-container")
.insertAfter(this.elem)
.css("width", this.$elem.attr("width")),
$innerContainer = $("<div />")
.addClass("yt-hd-thumbnail-inner-container")
.appendTo($outerContainer);
// insert thumbnail and iframe
if (this.settings.darkenThumbnail) {
this.$thumbnail.addClass("yt-hd-thumbnail-darken");
}
$innerContainer.append(this.$thumbnail).append(this.elem);
// add click handler to thumbnail
var self = this;
this.$thumbnail.on("click touchend", function(e) {
if (e.handled === false) return;
e.stopPropagation();
e.preventDefault();
e.handled = true;
src = src + "&autoplay=1";
$innerContainer.addClass("yt-hd-thumbnail-clicked");
self.$elem.attr({
src: src
});
});
}
});
$.fn["youTubeHDThumbnail"] = function(options) {
return this.each(function() {
if (!$.data(this, "plugin_" + "youTubeHDThumbnail")) {
$.data(
this,
"plugin_" + "youTubeHDThumbnail",
new YouTubeHDThumbnail(this, options)
);
}
});
};
})(jQuery, window, document);

我发现一种使用 touchend 的方法似乎可以解决问题。如果有人有一个修复程序，不需要我将其添加到我的所有点击功能中，我很想知道。
var self = this;
this.$thumbnail.on('click touchend', function(e) {
if (e.handled === false) return;
e.stopPropagation();
e.preventDefault();
e.handled = true;
src = src + '&autoplay=1';
$innerContainer.addClass('yt-hd-thumbnail-clicked');
self.$elem.attr({
'src': src
});
});
