VUEJS 2.0 child component accesses/calls parent component
The following is an example of how a VUEJS 2.0 subcomponent accesses/calls a parent component. It has a very good reference value and I hope it will be helpful to everyone.
Sometimes due to layout problems, the child component needs to pass data to the parent component and execute a certain method of the parent. I won’t go into the code:
Child Component:
<template>
<p class="isShowing" ref="isShowing">
<p class="menu-wrapper" ref="scroll_warpper" v-show="!hid_show_switch">
<ul ref="scroll_warpper_ul">
<li class="menu-item" @click="goToFatherDetail(233)">
</li>
</ul>
</p>
<v-loading class="isloading" v-show="hid_show_switch"></v-loading>
</p>
</template>
<script type="text/ecmascript-6">
export default {
methods: {
goToFatherDetail (itemId) {
// this.$parent.$router.push('goToDetail');
console.log('子组件方法走了' + itemId);
this.$emit('refreshbizlines', itemId); /* <span style="font-family: Arial, Helvetica, sans-serif;">itemId就是子要传的数据 - 这里很重要,refreshbizlines就是父组件$on监测的自定义函数不是父组件的自定义函数。*/</span>
}
}
};
</script>Parent component:
<template>
<p class="main-wrapper">
<p class="tab-wrapper">
<p class="tab-item">
<router-link to="/isShowing" class="table-item-text">正在热映</router-link>
</p>
<p class="tab-item">
<router-link to="/willShow" class="table-item-text">即将上映</router-link>
</p>
</p>
</p>
<router-view class="items-show" v-on:refreshbizlines="goToDetail" keep-alive></router-view>
</p>
</template>
<script type="text/ecmascript-6">
export default {
methods: {
goToDetail (itemId) {
console.log('父组件走你：' + itemId);
}
}<strong>
};
</script></strong>The parent component uses v-on to make a monitoring function to detect. The final generated code is similar to
on: {
"refreshbizlines": function($event) {
_vm.goToDetail(123)
}
}So the principle is that the child component accesses the detection function refreshbizlines of the parent component. If accessed, the function below refreshbizline is executed
goToDetail -- that is, the parent component's
goToDetail function
Note that the
v-on:refreshbizlines="goToDetail"
of the parent component must be placed on the module name of your parent component calling the child component.
Wish you happy coding.
