In my view, it is advisable to steer clear of directly manipulating the DOM. How about substituting ref with v-html instead?
const guideTutorial = guide => ({
mounted() {
guide['add-location'].forEach(step => {
this[step.ref] += this.html;
})
},
data: function() {
return {
...guide['add-location'].reduce((result, step) => {
result[step.ref] = ''
return result
}, {}),
html: `<p>Test</p>`
}
}
});
const SampleComponent = {
template: `
<div>
<div v-html='foo'></div>
<div v-html='bar'></div>
</div>
`,
mixins: [guideTutorial({
'add-location': [
{ ref: 'foo' },
{ ref: 'bar' }
]
})]
}
An alternative approach is to use a wrapper component to envelop the target element or if the target is a component, then create a mixin as well.
Utilizing the html property:
<wrapper ref='foo'>
<div>Foo</div>
</wrapper>
const Wrapper = {
props: ['html'],
render(h) {
return h('div', [this.$slots.default, h('div', {
domProps: {
innerHTML: this.html
}
})])
}
}
...
this.$refs.foo.html = '<h1>Hello Foo</h1>'
Example
Alternatively, using a custom appendChild method:
const Wrapper = {
data: () => ({
children: []
}),
methods: {
appendChild(child) {
this.children.push(child)
}
},
render(h) {
return h('div', [
this.$slots.default,
...this.children.map(child => h('div', {
domProps: {
innerHTML: child
}
}))
])
}
}
...
this.$refs.foo.appendChild('<h1>Hello Foo</h1>')
this.$refs.foo.appendChild('<h1>Hello Bar</h1>')
Example
Or utilizing Vue.compile in scenarios where the HTML content is not plain HTML:
const Wrapper = {
data: () => ({
template: '',
context: {}
}),
methods: {
setChild(template, context) {
this.template = template
this.context = context
}
},
render(h) {
let res = Vue.compile(this.template)
return h('div', [
this.$slots.default,
h({
data: () => this.context,
render: res.render,
staticRenderFns: res.staticRenderFns
})
])
}
}
...
this.$refs.foo.setChild('<h1>Hello {{ name }}</h1>', {
name: 'Foo'
})
