在工作中效率要求是很高的,现在就在频繁用到复选框,我们自己来写了个组件,增加其复用性,提高效率。
先看效果图:
这样只需提交后得到一个选中项的id组成的数组
下边直接上代码:
代码地址为:components/checkGrop/checkGrop
wxml:
<form bindsubmit="formSubmit"> <view class='content'> <!-- 一级菜单 --> <scroll-view class='scrollLeft' scroll-y> <block wx:for="{{list}}" wx:key="item"> <view class="leftBox" catchtap='ontap' data-index='{{index}}' style='{{n==index?"border-left:8rpx solid #1aad16;color:#1aad16":""}}'> {{item.istitle}} <view class='num' hidden="{{checked[index].length>0?false:true}}"> <text>{{allNum[index]?allNum[index]:(checked[index].length>0?checked[index].length:0)}}</text> </view> </view> </block> </scroll-view> <!-- 二级菜单 --> <scroll-view class='scrollRight' scroll-y> <view class="weui-cells weui-cells_after-title"> <!-- 二级菜单中的全部选项 --> <label class="weui-cell weui-check__label" catchtap='all'> <checkbox class="weui-check" value="{{childlist[n][0].value}}" checked="{{childlist[n][0].checked}}" /> <view class="weui-cell__hd weui-check__hd_in-checkbox"> <icon class="weui-icon-checkbox_circle" type="circle" size="23" wx:if="{{!childlist[n][0].checked}}"></icon> <icon class="weui-icon-checkbox_success" type="success" size="23" wx:if="{{childlist[n][0].checked}}"></icon> </view> <view class="weui-cell__bd">{{childlist[n][0].istitle}}</view> </label> <checkbox-group bindchange="checkboxChange"> <!-- 二级菜单中的剩余选项 --> <block wx:for="{{childlist[n]}}" wx:key="value"> <label class="weui-cell weui-check__label" wx:if='{{item.istitle!="全部"}}'> <checkbox class="weui-check" value="{{item.id}}" checked="{{item.checked}}" /> <view class="weui-cell__hd weui-check__hd_in-checkbox"> <icon class="weui-icon-checkbox_circle" type="circle" size="23" wx:if="{{!item.checked}}"></icon> <icon class="weui-icon-checkbox_success" type="success" size="23" wx:if="{{item.checked}}"></icon> </view> <view class="weui-cell__bd">{{item.istitle}}</view> </label> </block> </checkbox-group> </view> </scroll-view> </view> <view class="btn-area"> <button catchtap='back'>返回</button> <button formType="submit">提交</button> </view> </form>

json:
{ "component":true }
js:
Component({ properties: { list: { type: Array, value: [], }, select:{ type: Array, value: [], } }, data: { childlist: [], n: 0, checked: [], allNum: [], }, ready(){ var that=this; var list = that.data.list;//传递过来的数据 // console.log(list) var select = that.data.select; var checked = new Array; var allNum = []; var aaa = []; // 检查默认选中状态 for (let i = 0; i < list.length; i++) { for (let k = 0; k < list[i].childlist.length; k++) { for (let j = 0; j < select.length; j++) { if (list[i].childlist[k].id == select[j]) { aaa = []; // 若某条二级数组中存在多个选中的项要做判断筛选 if (checked[i]) { // check中第i项如果存过值,那么将在此项中继续加入值 checked[i].forEach(function (item) { aaa.push(item); }) aaa.push(list[i].childlist[k]); checked[i] = aaa; } else { // check中第i项没有存过值,那么将值存入第i项 if (list[i].childlist[k].istitle == "全部") { for (let s = 0; s < list[i].childlist.length; s++) { list[i].childlist[s].checked = true allNum[i] = list[i].childlist.length - 1; checked[i] = [list[i]]; } } else { checked[i] = [list[i].childlist[k]]; } } list[i].childlist[k].checked = true; } } } } that.setData({ 'childlist[0]': list[0].childlist, list: list, checked: checked, allNum: allNum, }) console.log(checked); console.log(allNum); }, methods: { ontap(e) { var that = this; var n = e.currentTarget.dataset.index; var childlist = "childlist[" + n + "]"; that.setData({ [childlist]: that.data.list[n].childlist, n: n }) }, all() { var that = this; var n = that.data.n; var childlist = "childlist[" + n + "]"; var checked = "checked[" + n + "]"; var allNum = "allNum[" + n + "]"; var all = ""; var checkArr = []; var checkboxItems = that.data.childlist[n]; if (checkboxItems[0].checked) { checkboxItems[0].checked = true; checkArr = []; } else { checkboxItems[0].checked = false; // checkArr.push(checkboxItems[0]) checkArr.push(that.data.list[n]) all = checkboxItems.length - 1; } checkboxItems[0].checked = !checkboxItems[0].checked for (let k = 1; k < checkboxItems.length; k++) { checkboxItems[k].checked = checkboxItems[0].checked; } console.log(checkboxItems); that.setData({ [childlist]: checkboxItems, [checked]: checkArr, [allNum]: all ? all : 0, }, function () { console.log(that.data.checked); }) }, checkboxChange(e) { var that = this; var n = that.data.n; console.log('checkbox发生change事件,携带value值为:', e.detail.value) var checkboxItems = that.data.childlist[n]; var values = e.detail.value; var flag = ""; var childlist = "childlist[" + n + "]"; var checked = "checked[" + n + "]"; var allNum = "allNum[" + n + "]"; var checkedArr = []; var all = ""; for (var i = 0, lenI = checkboxItems.length; i < lenI; ++i) { checkboxItems[i].checked = false; for (var j = 0, lenJ = values.length; j < lenJ; ++j) { if (checkboxItems[i].id == values[j]) { checkboxItems[i].checked = true; checkedArr.push(checkboxItems[i]); break; } } } if (values.length == checkboxItems.length - 1) { checkboxItems[0].checked = true; // checkedArr = [checkboxItems[0]]; checkedArr = [that.data.list[n]]; all = checkboxItems.length - 1; } this.setData({ [childlist]: checkboxItems, [checked]: checkedArr, [allNum]: all }); // console.log(checkedArr) }, formSubmit: function (e) { var that = this; console.log('form发生了submit事件'); var values = that.data.checked; var arr = []; var arr1 = []; for (let i = 0; i < values.length; i++) { if (values[i] != undefined) { arr.push(values[i]); } } for (let i = 0; i < arr.length; i++) { for (let j = 0; j < arr[i].length; j++) { arr1.push(arr[i][j]) } } console.log(arr1);//选中的值 var detail = arr1; this.triggerEvent("formSubmit", detail); }, back() { this.triggerEvent("back"); } } })
使用方法:
在需要使用的页面的json中声名启用组件
如: { "usingComponents": { "check": "/components/checkGrop/checkGrop" } }
然后在需要使用的页面的wxml中使用自己起的组件名就好了
如:
<check list="{{hangye}}" select="{{checkedid}}" bind:formSubmit="formSubmit" bindback="back"></check>
上面的代码,就是表示list 是用来往组件里传递的数组。 select为默认选中的的数据的id,这样就可以让参数依照自己的需求进行更换!
