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)
}
}
})
