javascript - vue中自定义事件如何传递参数？

问题描述

如代码所示，在子组件中定义和触发了select方法并将type参数传入，在父组件中引入子组件，并监听select事件

结果报错：“Property or method 'type' is not defined on the instance but referenced during render.” 是我传递参数的方法不对吗？

//子组件<button type='button' name='button' v-bind: v-on:click='select(2,$event)'> {{desc.all}} <span class='count'>{{ratings.length}}</span></button><script type='text/ecmascript-6'> methods:{ select:function (type,event) {if (!event._constructed){ return;}this.$emit(’select’,type) }</script>

//父组件<rating-select v-bind='{ratings:food.ratings,selectType:selectType,onlyContent:onlyContent}' v-on:select='updSelect(type)' v-on:toggleContent='toggleContent' class='rating-select'></rating-select><script> updSelect:function (type) {this.selectType = type }</script>

问题解答

v-on:select='updSelect'
