                Platforms <span class="caret"></span>
            </button>
            <ul class="dropdown-menu" role="menu" id = "buttonsPlace">

在我的 js 文件中：

for (i = 0; i < platformList.length; i++) {
        var li =  $("<li/>" , { id : "plat"+i,class : "dropdown" text : platformList[i]  } )
        //var text = document.createTextNode(platformList[i]);
        //li.appendChild(text);
        //btn.data("platform", platformList[i] );
         $("#buttonsPlace").append(li);

        $('.dropdown-menu').append('<li>Row '+countRows+'</li>');
