VueJS V模型自动转义HTML实体 [英] Vuejs v-model escape automatically html entities

问题描述

我正在尝试在表单文本输入中显示一些html实体，但是v-model似乎在转义它们.

I'm trying to display some html entities in a form text input, but v-model seems escaping them.

我需要写些什么来使v-model正确显示html实体吗?

Is there something I need to write to make v-model displaying correctly html entities?

我的示例代码是

<el-input v-model="data" readonly="readonly"></el-input>

我了解v-html，但是由于自动双向绑定，我更喜欢继续使用v-model.

I know about v-html but I prefer keep using v-model due the automatic two-way binding.

也许我表达了自己的错误，我想显示字符，而不是html实体，所以相反，49.42₹我需要显示49.42₹.

Maybe I expressed myself wrong, I want to display the character, not the html entity, so instead 49.42₹ i need to display 49.42₹.

推荐答案

如果您对可以解释HTML实体的计算机进行v-建模，那么我认为您将获得想要的效果.您可以输入实体值，它将正确地解释它们.但是，它可能会过早地将&#8变成一个不同的字符；您必须输入#8377;然后返回并插入&.

If you v-model a computed that interprets HTML entities, I think you get the effect you want. You can type in entity values and it will interpret them correctly. However, it might prematurely turn &#8 into a different character; you have to type #8377; and then go back in and insert the &.

new Vue({
  el: '#app',
  data: {
    a: '49.42₹'
  },
  computed: {
    asText: {
      get() {
        return this.toText(this.a);
      },
      set(newValue) {
        this.a = newValue;
      }
    }
  },
  methods: {
    toText(html) {
      const div = document.createElement('div');

      div.innerHTML = html;
      return div.textContent;
    }
  }
})

<link href="//unpkg.com/element-ui@1.0.0-rc.3/lib/theme-default/index.css" rel="stylesheet"/>
<script src="//unpkg.com/vue/dist/vue.js"></script>
<script src="//unpkg.com/element-ui/lib/index.js"></script>

<div id="app">
  <el-input v-model="asText"></el-input>
  {{a}}
  <div v-html="a"></div>
</div>
