如何在div之间制作标签?我正在尝试在div之间切换以用作面板的选择选项。在特定div面板上选项卡时,其边框应变为活动状态。它不起作用,只有浏览器级别的选项卡。这是我到目前为止所尝试的......

   <script type="text/javascript">
       $(document).ready(function()
       {   
            $("div").keydown(function(e) 
            {
                if (e.which == 9) 
            {
                      $(this).css("border","4px solid gray");
            }
            });
       });
    </script>

    <div id="north"></div>
<div id="west"></div>
<div id="center"></div>

我想你可以这样做:

$(document).ready(function() {

    // ids of divs you want to cycle through
    var divs = ["north", "west", "center"];
    var startIndex = 0;


    $(document).keydown(function(e) {
        if (e.which == 9) {

            // remove previously applied border
            $("div").css("border", "");
            $("#" + divs[startIndex]).css("border", "4px solid gray");
            startIndex++;

            // reset to first one
            if(startIndex === divs.length) {
                startIndex = 0;                   
            }
        }

        // prevent "tabbing out" of the document view
        return false;
    });
});​
