Page的wxml中如果直接获取component的数据?
Component组件:
mycomponent.js:
Component({
properties: {
tabTitls:{
type:Array,
value:[],
observer:function(news,olds,path){
//console.log(news,olds);
}
},
tabListData:{
type:Array,
value:[]
}
},
data: {
tabIndex:0
},
methods: {
/**
* tab标题选中事件
*/
onTabTitleSelected: function (e){
var index = e.currentTarget.dataset.index;
this.setData({
//拿到当前索引并动态改变
tabIndex: index
})
},
/**
* swipe切换事件
*/
pagechange:function(e){
//console.log(e);
let tabIndex = e.detail.current;
this.setData({
tabIndex: tabIndex
})
},
}
})
mycomponent.wxml:
<view class="root-container" >
<view class="tab-bar" >
<text wx:for="{{tabTitls}}" wx:key="index" class="{{tabIndex == index ? 'title active' : 'title '}}" style="width:{{100/tabTitls.length}}%;" data-index="{{index}}" bindtap="onTabTitleSelected">{{item}}</text>
</view>
<swiper class="swiper-view" indicator-dots="{{false}}" autoplay="{{false}}" bindchange="pagechange" current="{{tabIndex}}">
<swiper-item class="swiper" wx:for="{{tabTitls}}" wx:key="index" >
<!-- page页面需要获取 index -->
<slot> </slot>
</swiper-item>
</swiper>
</view>
Page页面:
testcomponent.js:
Page({
data: {
tabIndex:0,
tabTitls:["待支付","已完成","已取消","全部"],
tabListData:["1","2","3","4"]
},
})
testcomponent.wxml:
<mycomponent class="mycomponent" tabTitls="{{tabTitls}}" tabListData="{{tabListData}}">
<text>需要获取component的index:{{index}}</text>
</mycomponent>
请问:在page页面怎么获取component页面的index。
百度了很久,木有找到page直接获取component的数据,都是绑定事件去获取。
