微信小程序实现多选框全选与取消全选功能示例

page({
data: { select_all:false,
listData: [{code: "111",text: "text1",typ: "type1",},
{code: "021",text: "text2",typ: "type2",},
{code: "111",text: "text1",typ: "type3",}]}
selectall: function() {//全选与反全选
var that = this;
for (let i = 0; i < that.data.listData.length; i++) {
that.data.listData[i].checked = (!that.data.select_all)}
that.setData({
listData: that.data.listData,
select_all: (!that.data.select_all)
})}
})
