具体怎么通过js来控制switch开关？

同问

<div style="float:right;padding-right: 15px;">  
                <p style="display: inline-block;margin: 0;font-size: 18px;padding: 0;margin: 0;line-height: 50px;" id="txtBtn">切换模式</p>  
                <div style="float: right;display: inline-block;line-height: 50px;margin-top: 10px;margin-left: 10px;">  
                    <div class="mui-switch mui-switch-mini mui-switch-blue" id="switch">  
                        <div class="mui-switch-handle"></div>  
                    </div>  
                </div>  
            </div>  

document.getElementById("txtBtn").addEventListener("click", function(event) {  
                mui("#switch").switch().toggle();  
});
