html5语音即时聊天|仿微信语音效果|表情|定位

h5+css3语音实时聊天系统|仿微信语音聊天|js音频录制|仿微信地图定位

基于html5开发的仿微信语音聊天系统weChatIM项目，采用了h5+css3+jQuery+swiper+wcPop+mescroll等技术选型开发，实现了下拉刷新消息，发送信息、表情，预览大图、视频，红包、语音、地图定位等新增功能。

◆ meScroll下拉刷新消息

/*
 *	下拉刷新、上拉加载更多演示demo
 */

//创建MeScroll对象
var mescroll = new MeScroll("mescroll", {
		// 上拉刷新配置
		down : {
			auto : true, //是否在初始化完毕之后自动执行下拉回调callback; 默认true
			callback : downCallback, //下拉刷新的回调
			textInOffset : '下拉刷新',
			textOutOffset : '释放立即刷新',
			textLoading : '正在刷新...'
		},

		// 下拉加载配置
		up: {
		auto: true, //是否在初始化时以上拉加载的方式自动加载第一页数据; 默认false
		isBounce: false, //此处禁止ios回弹,解析(务必认真阅读,特别是最后一点): http://www.mescroll.com/qa.html#q10
		callback: upCallback, //上拉回调,此处可简写; 相当于 callback: function (page) { upCallback(page); }
		}
	});

/*下拉刷新的回调 */
function downCallback() {
	//联网加载数据
	getListDataFromNet(0, 1, function (data) {
		mescroll.endSuccess();
		//设置列表数据
		setListData(data, false);
	}, function () {
		mescroll.endErr();
	});
}

/*上拉加载的回调 page = {num:1, size:10}; num:当前页 从1开始, size:每页数据条数 */
function upCallback(page) {
	//联网加载数据
	getListDataFromNet(page.num, page.size, function (curPageData) {
		//联网成功的回调,隐藏下拉刷新和上拉加载的状态;
		mescroll.endSuccess(curPageData.length);
		//设置列表数据
		setListData(curPageData, true);
	}, function () {
		//联网失败的回调,隐藏下拉刷新和上拉加载的状态;
		mescroll.endErr();
	});
}

/*设置列表数据*/
function setListData(curPageData, isAppend) {
	var listDom = document.getElementById("newsList");
	for (var i = 0; i < curPageData.length; i++) {
		var newObj = curPageData[i];

		var str = '<p>' + newObj.title + '</p>';
		str += '<p class="new-content">' + newObj.content + '</p>';
		var liDom = document.createElement("li");
		liDom.innerHTML = str;

		if (isAppend) {
			listDom.appendChild(liDom); //加在列表的后面,上拉加载
		} else {
			listDom.insertBefore(liDom, listDom.firstChild); //加在列表的前面,下拉刷新
		}
	}
}

var downIndex = 0;
function getListDataFromNet(pageNum, pageSize, successCallback, errorCallback) {
	//延时一秒,模拟联网
	setTimeout(function () {
		try {
			var newArr = [];
			if (pageNum == 0) {
				//此处模拟下拉刷新返回的数据
				...ajax
			} else {
				//此处模拟上拉加载返回的数据
				...ajax
			}
			//联网成功的回调
			successCallback && successCallback(newArr);
		} catch (e) {
			//联网失败的回调
			errorCallback && errorCallback();
		}
	}, 1000)
}

◆ 语音按住说话功能模块

// >>> 【按住说话核心模块】------------------------------------------
// ...按住说话
var _voiceObj = $(".J__wdtVoice"), eY1 = 0, eY2 = 0, eY3 = 0, isDrag = true;
var voiceIdx;
var difftime = 0;
function initVoice(){
	_voiceObj.on("touchstart", function(e){
		difftime = new Date();
		if(!isDrag) return;
		isDrag = false;
		eY1 = e.originalEvent.targetTouches[0].pageY;
		_voiceObj.text("松开 结束");

	});
}

◆ 获取audio语音时长：duration 及播放语音

// ...获取语音时长
getVoiceTime();
function getVoiceTime(){
	$("#J__chatMsgList li .audio").each(function () {
		var that = $(this), audio = that.find("audio")[0], duration;
		audio.load();
		audio.oncanplay = function(){
			duration = Math.ceil(audio.duration);
			if (duration == 'Infinity') {
				getVoiceTime();
			} else {
				that.find(".time").text(duration + `''`);
				that.attr("data-time", duration);
				// 语音宽度%
				var percent = (duration / 60).toFixed(2) * 100 + 20 + '%';
				that.css("width", percent);
			}
		}
	});
}

// ...语音播放事件
var timer = null;
$("body").on("click", "#J__chatMsgList li .audio", function () {
	var that = $(this);
	that.parents("li").siblings("li").find(".ico_voice").removeClass("active");
	that.find(".redot").addClass("off");

	// audio播放事件
	timer && clearTimeout(timer);
	that.parents("li").siblings("li").find("audio")[0].pause();
	var audio = that.find("audio")[0], time = that.attr("data-time");
	if(audio.paused){
		audio.play();
		that.find(".ico_voice").addClass("active");
		timer = setTimeout(function(){
			that.find(".ico_voice").removeClass("active");
		}, time*1000);
	}else{
		audio.pause();
		that.find(".ico_voice").removeClass("active");
		clearTimeout(timer);
	}
});
