Component template should contain exactly one root element. If you are using v-i
今天在學習vue元件的巢狀時頁面報錯。
大概的意思是:元件模板應該包含一個根元素。
錯誤程式碼:
var childComponent = Vue.extend({
template: '<div>this is child template</div>'
});
Vue.component("parent",{
template: '<div>this is parent template</div><child></child>',
//正確程式碼
// template: '<p>this is parent template<child></child></p>'
components: {
'child': childComponent,
}
});
var app = new Vue({
el: '#app'
});
原來,我們在使用元件的時候。需要使用div或者p標籤等將其包起來
