vue.js:634 [Vue warn]: Invalid handler for event “click”: got undefined
Vue运行报错，记录一下原因。
报错代码如下
HTML
<div id="app">
<button type="button" @click="clickCount">You have click me {{count}} times
</button>
<button type="button" @click="clickCount2">You have click me {{count}} times
</button>
</div>
JavaScript
var app
= new Vue({
el
:'#app',
data
:{
count
:0
},
computed
:{
clickCount
:function(){
this.count
++;
}
},
methods
:{
clickCount2
:function(){
this.count
++;
}
}
})
原因
click调用函数与计算属性时应带上括号（）
<div id="app">
<button type="button" @click="clickCount（）">You have click me {{count}} times
</button>
<button type="button" @click="clickCount2（）">You have click me {{count}} times
</button>
</div>
