请问向二维数组赋值后，view为什么取不到值？ - WXOPEN Club

page ｛

data: {

i_1: [

[{ name: '是1', value: '1'},{ name: '否', value: '0' }],

[{ name: '是2', value: '1' },{ name: '否', value: '0' }]

],

questions: ["1.AAA",

"2.BBB"],

}

radioChange: function (e) {

var that = this;

console.log('radio发生change事件，携带value值为：', e.detail.value);

console.log('11223',e.currentTarget.dataset.index)

var index = e.currentTarget.dataset.index;

var radioItems = that.data.i_1[index];

for (var i = 0, len = radioItems.length; i < len; ++i) {

radioItems[i].checked = radioItems[i].value == e.detail.value;

}

var objName = "i_1["+index+"].text";

that.setData({

objName: radioItems

});

console.log("fuzhi:::::::",this.data.i_1);

},

｝

从console里可以看到，对象已经被赋值成功，但是 view里取到是空

<block wx:for="{{questions}}" wx:key="q">

<view class="weui-cells__title">{{item}}</view>

<view class="weui-cells weui-cells_after-title">

<radio-group data-index="{{index}}" bindchange="radioChange">

<label class="weui-cell weui-check__label" wx:for="{{i_1[index]}}" wx:for-item="j" wx:key="value">

<radio class="weui-check" value="{{j.value}}" checked="{{j.checked}}"/>

<view class="weui-cell__bd">{{j.name}}</view>

<view class="weui-cell__ft weui-cell__ft_in-radio" wx:if="{{j.checked}}">

<icon class="weui-icon-radio" type="success_no_circle" size="16"></icon>

</view>

</label>

</radio-group>

</view>

</block>

应该怎么写，才能让view取到 checked 属性？
