vue.js全局消息组件

  这里总结了一个简单的实现全局消息通知的方法，实现的效果如下图：

1、修改/src/App.vue文件，中增加消息控件，放在<router-view/>后面

<div class="ant-message">
    <div class="ant-content">
      <div class="ant-message-notice" 
            :class="[type=='success'?'ant-message-success':'',
                    type=='error'?'ant-message-error':'',
                    type=='info'?'ant-message-info':'',
                    type=='warning'?'ant-message-warning':'']">
          <span>{{message}}</span>
      </div>
    </div>
</div>

2、同样在/src/App.vue文件中，在中增加样式：       //不能加scoped

.ant-message{
    position: fixed;
    z-index: -1;
    width:100%;
    top: 51px;
  }
  .ant-content{
    font-family: "Helvetica Neue For Number", -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "Helvetica Neue", Helvetica, Arial, sans-serif;
    font-size: 14px;
    line-height: 1.5;
    color: rgba(0, 0, 0, 0.65);
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
    pointer-events: none;
    display: inline-block;
  }
  .ant-message-notice{
    padding:16px 30px;
    font-size: 16px;
    color:black;
    border-radius: 4px;
    box-shadow:0 4px 12px rgba(0,0,0,0.15);
    background: white;
    display: none;
    pointer-events: all;
    box-sizing:border-box;
  }
  .ant-message-error:before{
    content:"\f057";
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    font-size: 18px;
    margin-right:5px;
    z-index: 3;
    color:red;
  }
  .ant-message-info:before{
    content:"\f05a";
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    font-size: 18px;
    margin-right:5px;
    z-index: 3;
    color: #4d7dff;
  }
  .ant-message-warning:before{
    content:"\f071";
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    font-size: 18px;
    margin-right:5px;
    z-index: 3;
    color: #ffdd65;
  }
  .ant-message-success:before{
    content:"\f058";
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    font-size: 18px;
    margin-right:5px;
    z-index: 3;
    color: #3da638;
  }

3、 在src/main.js中增加全局函数（$message）：

Vue.prototype.$message = function(option){
  $('.ant-message-notice span').html(option.text)
  $('.ant-message-notice').addClass('ant-message-'+option.type)
  $('.ant-message').css('z-index',9999)
  $ ('.ant-message-notice').show ().delay (3000).fadeOut (function () {
            $('.ant-message').css('z-index',-1)
          });
}

4、在需要弹出消息提示的时候使用this.$message({"type": "warning", "text": "message"})即可
