介绍

  • 支持文本和图片的展示(后续将支持对语音类的展示)。
  • 支持滚动加载数据,其中滚动加载依赖我另外一个组件scrollLoader.vue(《Vue.js上下滚动加载组件》)。
  • 支持QQ表情,为了能使用表情请全局注册指令v-emotion,我在main.js做了实现;代码如下:
function toEmotion(text, isNoGif){
    var list = ['微笑', '撇嘴', '色', '发呆', '得意', '流泪', '害羞', '闭嘴', '睡', '大哭', '尴尬', '发怒', '调皮', '呲牙', '惊讶', '难过', '酷', '冷汗', '抓狂', '吐', '偷笑', '愉快', '白眼', '傲慢', '饥饿', '困', '惊恐', '流汗', '憨笑', '大兵', '奋斗', '咒骂', '疑问', '嘘', '晕', '折磨', '衰', '骷髅', '敲打', '再见', '擦汗', '抠鼻', '鼓掌', '糗大了', '坏笑', '左哼哼', '右哼哼', '哈欠', '鄙视', '委屈', '快哭了', '阴险', '亲亲', '吓', '可怜', '菜刀', '西瓜', '啤酒', '篮球', '乒乓', '咖啡', '饭', '猪头', '玫瑰', '凋谢', '示爱', '爱心', '心碎', '蛋糕', '闪电', '炸弹', '刀', '足球', '瓢虫', '便便', '月亮', '太阳', '礼物', '拥抱', '强', '弱', '握手', '胜利', '抱拳', '勾引', '拳头', '差劲', '爱你', 'NO', 'OK', '爱情', '飞吻', '跳跳', '发抖', '怄火', '转圈', '磕头', '回头', '跳绳', '挥手', '激动', '街舞', '献吻', '左太极', '右太极', '嘿哈', '捂脸', '奸笑', '机智', '皱眉', '耶', '红包', '鸡'];
    if (!text) {
        return text;
    }

    text = text.replace(/\[[\u4E00-\u9FA5]{1,3}\]/gi, function(word){
        var newWord = word.replace(/\[|\]/gi,'');
        var index = list.indexOf(newWord);
        var backgroundPositionX = -index * 24
        var imgHTML = '';
        if(index<0){
            return word;
        }

        if (isNoGif) {
            if(index>104){
                return word;
            }
            imgHTML = `<i class="static-emotion" style="background:url(https://res.wx.qq.com/mpres/htmledition/images/icon/emotion/default218877.gif) ${backgroundPositionX}px 0;"></i>`
        } else {
            var path = index>104 ? '/img' : 'https://res.wx.qq.com/mpres/htmledition/images/icon';
            imgHTML = `![](${path}/emotion/${index}.gif)`
        }
        return imgHTML;
    });
    return text;
}


Vue.directive('emotion', {
    bind: function (el, binding) {
        el.innerHTML = toEmotion(binding.value)
    }
});

##如何使用? 参数已经在组件中做了说明,并在App.vue中做了演示: 参数和说明: 微信聊天可视化组件 依赖scrollLoader组件, 依赖指令v-emotion(实现请查看main.js)

参数width 组件宽度,默认450 wrapBg 外层父元素背景颜色,默认#efefef maxHeight 展示窗口最高高度, 默认900 contactAvatarUrl 好友头像url ownerAvatarUrl 微信主人头像url ownerNickname 微信主人昵称 getUpperData (必需)当滚动到上方时加载数据的方法,返回值要为Promise对象,resolve的结构同data getUnderData (必需)当滚动到下方时加载数据的方法,返回值同上 data (必需)传入初始化数据, 结构如下:

[{
    direction: 2, //为2表示微信主人发出的消息,1表示联系人
    id: 1, //根据这个来排序消息
    type: 1, //1为文本,2为图片
    content: '你好!![呲牙]', //当type为1时这里是文本消息,当type2为2时这里要存放图片地址;后续会支持语音的显示
    ctime: new Date().toLocaleString() //显示当前消息的发送时间
},
{
    direction: 1,
    id: 2,
    type: 1,
    content: '你也好。[害羞]',
    ctime: new Date().toLocaleString()
}]
