Render Component in iframe using vuejs without src attribute
The easiest way for me is to use srcdoc attribute. It loads raw html overriding src attribute.
<template>
<iframe :srcdoc="html"></iframe>
</template>
Update: More detail example: Consider a textarea for a user html input and want to display in an iframe.
<template>
<div id="app">
<textarea v-model="html"></textarea>
<iframe :srcdoc="html"></iframe>
</div>
</template>
<script>
export default {
name: "App",
data(){
return {
html:"<h1>Hello I am H1 block</h1>"
}
}
};
</script>
I've tried and haven't found a way to mount vue directly on #iframe.
Yet, you can add div to #iframe and mount to that:
// create iframe element
var iframe = document.createElement('iframe')
iframe.id = 'iframe'
// place iframe inside page html
document.documentElement.insertBefore(iframe, document.querySelector('html').firstChild)
// append div to iframe
var container = document.createElement('div')
container.id = 'container'
iframe.contentWindow.document.body.appendChild(container)
// render vue component inside iframe on #container
new Vue({
el: container,
render: h => h(component)
})
Result:
<html>
<iframe id="iframe">
#document
<html>
<head>
</head>
<body><!-- <-- here was <div id="container"></div> -->
<div class="message" style="color: orange;">Hello from Vue component!</div>
</body>
</html>
</iframe>
<head>
</head>
<body>
</body>
</html>
P.s. I've used this code in chrome extension content scripts (javascript injected into pages). If you're going to use it elsewhere make sure not to break Same-origin policy.
You can refer below link That helped me a lot. Here is the link and the code snippets.
Vue.component('i-frame', {
render(h) {
return h('iframe', {
on: { load: this.renderChildren }
})
},
beforeUpdate() {
//freezing to prevent unnessessary Reactifiation of vNodes
this.iApp.children = Object.freeze(this.$slots.default)
},
methods: {
renderChildren() {
const children = this.$slots.default
const body = this.$el.contentDocument.body
const el = document.createElement('DIV') // we will mount or nested app to this element
body.appendChild(el)
const iApp = new Vue({
name: 'iApp',
//freezing to prevent unnessessary Reactifiation of vNodes
data: { children: Object.freeze(children) },
render(h) {
return h('div', this.children)
},
})
iApp.$mount(el) // mount into iframe
this.iApp = iApp // cache instance for later updates
}
}
})
Vue.component('test-child', {
template: `<div>
<h3>{{ title }}</h3>
<p>
<slot/>
</p>
</div>`,
props: ['title'],
methods: {
log: _.debounce(function() {
console.log('resize!')
}, 200)
},
mounted() {
this.$nextTick(() => {
const doc = this.$el.ownerDocument
const win = doc.defaultView
win.addEventListener('resize', this.log)
})
},
beforeDestroy() {
const doc = this.$el.ownerDocument
const win = doc.defaultView
win.removeEventListener('resize', this.log)
}
})
new Vue({
el: '#app',
data: {
dynamicPart: 'InputContent',
show: false,
}
})
