源码：

bindMultiPickerColumnChange: function (e) {

var jectMul = new Array;

var data = {

objectMultiArray: this.data.objectMultiArray,

multiIndex: this.data.multiIndex

};

data.multiIndex[e.detail.column] = e.detail.value;

var that = this;

wx.request({

url: AppData.AppConfigData.weburl + ‘/WxForm/WebClass2.html’,

data: { cid: data.objectMultiArray[0][e.detail.value].id },

method: ‘GET’,

header: { ‘content-type’: ‘application/json’ },

success: function (res) {

that.setData({

jectMul: res.data

})

}

});

this.data.objectMultiArray[1] = this.data.jectMul;

console.log(‘asdasd值22为’, this.data);

console.log(‘asdasd值23332为’, jectMul);

data.multiIndex[1] = 0;

this.setData(this.data);

},

这个是一个二级联动分类选择器。选择一级后，根据ID读数据库显示二级。

this.data  显示 jectMul  是实时数据

但 this.data.jectMul  是不确定数据！！

怎么才能使  this.data.objectMultiArray[1] = this.data.jectMul;   这个等式成立。每次调用都准确替换objectMultiArray的值
