 { id: 2, name: 2, checked: false },
 { id: 3, name: 3, checked: false },
 { id: 4, name: 4, checked: false },
 ],
 selectilall: false
 },

//单选
 select: function (e) {
 let selectValue = e.currentTarget.dataset.name
 let index = e.currentTarget.dataset.index;
 let list = this.data.list
 let newli = 'list[' + index + '].checked';
 this.setData({
 [newli]: !this.data.list[index].checked
 })
 let num = 0;
 for(var i=0;i<this.data.list.length;i++){
 if(this.data.list[i].checked){
 num++;
 }
 }
 if(num == this.data.list.length){
 this.setData({
 selectilall: true
 })
 }else{
 this.setData({
 selectilall: false
 })
 }
 },
 //全选,取消全选
 selectAll: function (e) {
 let list = this.data.list;
 let selectilall = this.data.selectilall;
 if (selectilall == false) {
 for (let i = 0; i < list.length; i++) {
 let newli = 'list[' + i + '].checked';
 this.setData({
 [newli]: true,
 selectilall: true
 })
 }
 } else {
 for (let i = 0; i < list.length; i++) {
 let newli = 'list[' + i + '].checked';
 this.setData({
 [newli]: false,
