微信小程序自定义联系人弹窗
dlz_Mr 人气:1微信小程序自定义类似微信联系人组件,供大家参考,具体内容如下
在小程序项目中需要有一个选择人员项,想着看着好看一些,所以做成类似微信联系人的界面,由于本人是后端人员,效果不是特别好看,ui使用的是weui
效果图如下:
使用的是小程序自定义组件,自定义组件同样需要有js、wxss、json、wxml四个文件,
如何使自定义的组件,需要在json文件中声明
{ "component": true }
js文件中使用的Component构造器而不是Pge构造器,其中properties属性中声明组件中对外暴露的属性,该组件中暴漏了两个属性:
show:布尔值,控制联系人组件是否显示,
list:数组,联系人组件需要显示的人员,效果图左侧的字母导航栏组件中已经处理过了,基本汉字处理没有问题,会根据对象中name属性提取首字母,将数组进行排序分组,只需要传入原生数组即可
数组的是多个Object对象,该对象需必备两个属性:
{ name: "火男", //联系人显示的名称 photo: "http://aaa/img.png"//联系人的头像,如果不指定,会使用默认的图片 }
组件通信,设置三个事件回调函数
cancle: 组件上方搜索栏取消按钮回调
select:选中某个联系人后的回调,会将选中的人员对象发送到父组件中
confirmInput:上方搜索框键盘按下完成后的回调,会将输入框中的值发送到父组件中
使用方法:
在组件标签中使用bindselect="",bindconfirmInput="",bindcancle=""绑定父组件中的回调
js文件:
var pinyin = require('./pinyin.js') Component({ /** * 组件的属性列表 */ properties: { //是否显示联系人 show: { type: Boolean, value: false }, //用户数组 list: { type: Array, value: [] } }, /** * 组件的初始数据 */ data: { nav: [], showList: [] }, observers: { 'list': function(list) { console.log('更新人员数据:', list) for (let user of list) { user['pinyin'] = pinyin.py.get(user.name).p if (!Boolean(user.photo)) { user['photo'] = "./resources/images/photo-boy.png"; } } var newlist = []; var nav = []; if (this.data.list.length > 0) { var sortUsers = pinyin.py.dataLetterSort(this.data.list, 'pinyin') for (let key in sortUsers) { var obj = {}; obj['title'] = key, obj['list'] = sortUsers[key] nav.push(key) newlist.push(obj); } } this.setData({ showList: newlist, nav: nav }) console.log(this.data.showList) } }, lifetimes: { // 生命周期函数,可以为函数,或一个在methods段中定义的方法名 attached() {}, moved() {}, detached() {}, }, /** * 组件的方法列表 */ methods: { toView: function(e) { console.log('toview',e) this.setData({ toViewNav: e.currentTarget.dataset.item, toView: e.currentTarget.dataset.item }) }, showInput: function() { this.setData({ inputShowed: true }); }, //输入框点击取消按钮 hideInput: function() { this.setData({ inputVal: "", inputShowed: false }); this.triggerEvent('cancle'); }, touchend: function() { console.log(11111111) setTimeout(() => { this.setData({ toViewNav: "" }) }, 500); }, clearInput: function() { this.setData({ inputVal: "" }); }, inputTyping: function(e) { this.setData({ inputVal: e.detail.value }); }, hideUsers: function() { this.setData({ show: false }) }, //选中某个联系人 select(e) { console.log("选中联系人",e) var myEventDetail = {} // detail对象,提供给事件监听函数 myEventDetail['user'] = e.currentTarget.dataset.user; var myEventOption = {} // 触发事件的选项 this.setData({ show: false }) this.triggerEvent('select', myEventDetail, myEventOption) }, //点击完成按钮 confirmInput: function (e) { console.log('点击键盘完成', e) var myEventDetail = {}//提供给事件监听函数 myEventDetail['value'] = e.detail.value; this.triggerEvent('confirm',myEventDetail) } } })
