自己在小程序中单独实现了同比绑定功能

<input style=‘color:#f00736;’ type=‘number’ placeholder=‘請輸入金額’ id=’{{index}}’ value=’{{item.value}}’ placeholder-class=‘com-phd-color’ bindchange=‘synchroValue’ bindfocus=‘synchroFilter’></input>

data: {

dataList: [

{

name: null,

value: null

}

]

},

synchroValue: function(e) {

let val = e.detail.value;

let id = e.target.id;

let data = this.data.dataList;

data[parseInt(id)].value = val;

this.setData({

dataList: data

});

}
