在 Vue.js 中显示未转义的 HTML

Question

How can I manage to get HTML interpreted inside a mustache binding? At the moment the break ( <br /> ) is just displayed/escaped.

Small Vue app:

var logapp = new Vue({
  el: '#logapp',
  data: {
    title: 'Logs',
    logs: [
      { status: true, type: 'Import', desc: 'Learn<br />JavaScript', date: '11.11.2015', id: 1  },
      { status: true, type: 'Import', desc: 'Learn<br />JavaScript', date: '11.11.2015', id: 1  }
    ]
  }
})

And here is the template:

<div id="logapp">    
    <table>
        <tbody>
            <tr v-repeat="logs">
                <td>{{fail}}</td>
                <td>{{type}}</td>
                <td>{{description}}</td>
                <td>{{stamp}}</td>
                <td>{{id}}</td>
            </tr>
        </tbody>
    </table>
</div>

Answer 1

You can use the v-html directive to show it. like this:

<td v-html="desc"></td>

Answer 2

Starting with Vue2, the triple braces were deprecated, you are to use v-html .

<div v-html="task.html_content"> </div>

It is unclear from the documentation link as to what we are supposed to place inside v-html , your variables goes inside v-html .

Also, v-html works only with <div> or <span> but not with <template> .

Answer 3

You can read that here

If you use

{{<br />}}

it'll be escaped. If you want raw html, you gotta use

{{{<br />}}}

EDIT (Feb 5 2017): As @hitautodestruct points out, in vue 2 you should use v-html instead of triple curly braces.

Answer 4

您必须使用 v-html 指令在 vue 组件中显示 html 内容

<div v-html="html content data property"></div>

Answer 5

Vue by default ships with the v-html directive to show it, you bind it onto the element itself rather than using the normal moustache binding for string variables.

So for your specific example you would need:

<div id="logapp">    
    <table>
        <tbody>
            <tr v-repeat="logs">
                <td v-html="fail"></td>
                <td v-html="type"></td>
                <td v-html="description"></td>
                <td v-html="stamp"></td>
                <td v-html="id"></td>
            </tr>
        </tbody>
    </table>
</div>

Answer 6

Before using v-html , you have to make sure that the element which you escape is sanitized in case you allow user input, otherwise you expose your app to xss vulnerabilities.

I highly encourage you that instead of using v-html to use this npm package
