js:

    data: {

    sumKey: [

    { "key": "替换a", "id": "1" },

    { "key": "替换b", "id": "2" }

    ],

    strArray: ['1', '啊','2'],

    },

wxss:

    <p wx:for="{{strArray}}" wx:for-item="strArray">

        <p wx:for-items="{{sumKey}}" wx:for-item="item">

            <p wx:if="{{item.id==strArray}}">

            {{item.key}}

            </p>

        </p>

        {{strArray}}

    </p>
