<stack-panel align-items="2">
    <behaviors>
        <script path="./Index.js" />
        <script private="true">
                    $el.dataContext = new Index();
                </script>
    </behaviors>
    <control size="100 44" background-color="white" selected="{{exp=selectJobNumber,mode=1}}" event-tap="js:this.onClicked()">
        <dock-panel>
            <lable text="normal" />
        </dock-panel>
        <selected>
            <dock-panel>
                <lable text="selected" />
            </dock-panel>
        </selected>
    </control>
    <control size="100 44" background-color="white" selected="{{exp=!selectJobNumber,mode=1}}" space-before="20" event-tap="js:this.onClicked()">
        <dock-panel>
            <lable text="normal" />
        </dock-panel>
        <selected>
            <dock-panel>
                <lable text="selected" />
            </dock-panel>
        </selected>
    </control>
</stack-panel>

下面是js代码

class Index{
    constructor(){
        this.selectJobNumber = true;
    }

    onClicked(){
        this.selectJobNumber = !this.selectJobNumber;
    }

}

实测是可以的
