VueJS - 单击时交换组件 [英] VueJS - Swap component on click

问题描述

在我的应用程序中，我有很多按钮.当我按下按钮时，我想加载一个模板(替换所选按钮):

模板:

Vue.component('component-1', {...});Vue.component('component-2', {...});

按钮:

<button>Button1</button><button>Button2</button>

在这种情况下，当我按下 Button1 时，div toReplace 的内容应该是 component-1.当然，每个组件都应该有一个关闭"按钮，在按下时会再次显示按钮(简而言之，div toReplace).

解决方案

您需要将一个变量绑定到 :is 属性.并在按钮单击时更改此变量.您还需要将它与一些 v-show 条件结合起来.像这样:

<div :is="currentComponent"></div><div v-show="!currentComponent" v-for="componentsArray 中的组件"><button @click="swapComponent(component)">{{component}}</button>

<button @click="swapComponent(null)">关闭</button>

new Vue({el: '身体',数据: {当前组件:空，componentsArray: ['foo', 'bar']},成分: {'富':{模板:'<h1>Foo 组件</h1>'},'酒吧': {模板:'<h1>条形组件</h1>'}},方法: {交换组件:功能(组件){this.currentComponent = 组件；}}});

这是一个简单的例子:

In my application I have many buttons. When I press it the button I would like to load a template (that replaces the selected button):

Templates:

Vue.component('component-1', {...});
Vue.component('component-2', {...});

Buttons:

<div id="toReplace">
  <button>Button1</button>
  <button>Button2</button>
</div>

In this case, when I press Button1 the content of the div toReplace should be component-1. Sure, each component should have a "close" button that will show the buttons again (in short, the div toReplace) on press.

解决方案

You need to bind a variable to :is property. And change this variable on button click. Also you will need to combine it with some v-show condition. Like so:

<div id="toReplace">
    <div :is="currentComponent"></div>
    <div v-show="!currentComponent" v-for="component in componentsArray">
      <button @click="swapComponent(component)">{{component}}</button>
    </div>
</div>
<button @click="swapComponent(null)">Close</button>

new Vue({
  el: 'body',
  data: {
    currentComponent: null,
    componentsArray: ['foo', 'bar']
  },
  components: {
    'foo': {
      template: '<h1>Foo component</h1>'
    },
    'bar': {
      template: '<h1>Bar component</h1>'
    }
  },
  methods: {
    swapComponent: function(component)
    {
      this.currentComponent = component;
    }
  }
});
