Question

我正在寻找一种方法来使用WhatsApp Web，就像内容可编辑div一样，当按下SHIFT + ENTER时会向上扩展，并相应地最小化它上面的div（参见附加屏幕截图中的紫色区域）。

实现这一目标的最佳方式是什么？

非常感谢。

编辑：我使用vuejs和vuetify。

Answer 1

我在css中使用变量.show-more { width: 80%; margin-left: auto; margin-right: auto; text-align: center; background-color: lightblue; position: absolute; margin-top: 275px; left: 0; right: 0; } clac height .converstion：https://www.w3schools.com/css/css3_variables.asp
<登记/> 我使用的是div，但您可以使用Jquery执行此事件 请参阅JSFiddle：https://jsfiddle.net/8feswyau/

＆＃13;

Vue JS

＆＃13;

$('textarea').on({input: function(){
    var totalHeight = $(this).prop('scrollHeight') - parseInt($(this).css('padding-top')) - parseInt($(this).css('padding-bottom'));
    $(this).css({'height':totalHeight});
    $('.conversation').get(0).style.setProperty("--number",totalHeight+'px')
}
});

＆＃13;

 textarea{
 width:243px;
 
 }
.warp{
height:300px;
width:250px;
}
.conversation{
 height: calc(100% - var(--number));
    position: relative;
    background: #efe7dd url(https://cloud.githubusercontent.com/assets/398893/15136779/4e765036-1639-11e6-9201-67e728e86f39.jpg) repeat;
 }

＆＃13;

这可以通过<v-text-field textarea auto-grow>和一些基本的flexbox轻松完成：https://codepen.io/anon/pen/jKaVZO

Answer 3

我最近不得不制作一个浮动按钮，以使用whatsapp API将邮件发送到一定数量。我创建了一个模拟WhatsApp聊天的聊天框。

基本上，它是由vue和vuetify令人难以置信的组件制成的

添加带有消息框的快速whatsapp浮动按钮以与您的用户联系。如果单击该按钮，则聊天框将打开，并带有预填充的消息。
