这几天使用H5开发了一个仿微信聊天前端界面,尤其微信底部编辑器那块处理的很好,使用HTML5来开发,虽说功能效果并没有微信那么全,但是也相当不错了,可以发送消息、表情,发送的消息自动回滚定位到底部,另外可以对消息、图片、视频有不同的右键处理提示,还有打赏、占屏等操作。
html代码片段:
<!--BEGIN 打赏--> <div class="js_dialog" id="J_Dialog_dashang" style="display: none;"> <!--<div class="weui-mask"></div>--> <div class="weui-dialog"> <i class="weui-xclose"></i> <div class="weui-dialog__bd"> <!-- //打赏模板区--> <div class="ws__popup-template"> <h2 class="hdTit">为喜欢的节目打赏</h2> <div class="item flexbox"> <input class="ipt-txt align-l flex1" type="text" name="dschooseProgram" placeholder="选择打赏节目" readonly /> </div> <div class="item item-area"> <textarea class="describe" name="content" placeholder="输入打赏语,30字以内(选填)"></textarea> </div> <div class="item item-gift" id="J__chooseGift"> <div class="gift flexbox selected" data-gift="001"> <label class="txt"><span>豪车</span><em class="time">霸屏50秒</em></label> <span class="amount">¥<em>12</em> <i class="chkbox"></i></span> </div> <div class="gift flexbox" data-gift="002"> <label class="txt"><span>动人玫瑰</span><em class="time">霸屏20秒</em></label> <span class="amount">¥<em>8</em> <i class="chkbox"></i></span> </div> </div> </div> </div> <div class="weui-dialog__ft"> <a href="javascript:;" class="weui-dialog__btn weui-dialog__btn_primary" style="background: #ff4400; border-radius: 4px; color: #fff;">支付 <span>¥<em class="moneyNum">12</em></span> 打赏</a> </div> </div> </div> <!--END 打赏-->
