如何通过单击图像 Vuetify 以编程方式下拉选择菜单? [英] How to drop down programmatically a select menu by clicking on image Vuetify?

问题描述

我有我的图像属性并在模板中选择:

<v-img src='/logos/some.jpg'@click='click_select'/>

在方法中，我有方法:

click_select(){this.$refs.select.onClick;}

点击图片不做任何事情，也没有错误日志

解决方案

只需为该事件添加一个回调处理程序，例如:

this.$refs.select.onClick((e) => {});

完整示例

var app = new Vue({el: '#app',vuetify: 新的 Vuetify(),数据: {货币选择:['a', 'b', 'c']},方法: {click_select() {this.$refs.select.onClick((e) => {});}}})

I have my image property and select in template:

<v-img src='/logos/some.jpg'
        @click='click_select'/>

<v-select :items="currencySelect" 
        ref='select'/>

and in methods, I have method:

click_select(){
  this.$refs.select.onClick;
}

Clicking on image doesn't do anything and no errors logs

解决方案

Just add a callback handler for that event like :

this.$refs.select.onClick((e) => {

  });

Full example

var app = new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data: {
    currencySelect: ['a', 'b', 'c']
  },

  methods: {
    click_select() {

      this.$refs.select.onClick((e) => {

      });
    }
  }
})
