展开/折叠表格行

Question

我想要一张展开或折叠的桌子。我的要求是当我点击表格行然后隐藏行显示或当我点击其他表格行然后上一个打开行隐藏或显示相对隐藏行。我找到了一个jquery jxpand非常适合我显示隐藏行但当我点击其他行时，之前的隐藏数据保持打开不隐藏我想要先前隐藏或显示新的相关行隐藏数据。我的代码段如下

$(document).ready(function(){
            $("#report tr:odd").addClass("odd");
            $("#report tr:not(.odd)").hide();
            $("#report tr:first-child").show();
            
            $("#report tr.odd").click(function(){
                $(this).next("tr").toggle();
                $(this).find(".arrow").toggleClass("up");
            });
            //$("#report").jExpand();
        });

#report { border-collapse:collapse;}
        #report h4 { margin:0px; padding:0px;}
        #report img { float:right;}
        #report ul { margin:10px 0 10px 40px; padding:0px;}
        #report th { background:#7CB8E2 url(header_bkg.png) repeat-x scroll center left; color:#fff; padding:7px 15px; text-align:left;}
        #report td { background:#C7DDEE none repeat-x scroll center left; color:#000; padding:7px 15px; }
        #report tr.odd td { background:#52edc7; cursor:pointer; }
        #report div.arrow { background:transparent url(arrows.png) no-repeat scroll 0px -16px; width:16px; height:16px; display:block;}
        #report div.up { background-position:0px 0px;}

Answer 1

只需在点击功能中添加$("#report tr:not(.odd)").hide();即可。

$("#report tr:odd").addClass("odd");
$("#report tr:not(.odd)").hide();
$("#report tr:first-child").show();

$("#report tr.odd").click(function () {
    $("#report tr:not(.odd)").hide();
    $(this).next("tr").toggle();
    $(this).find(".arrow").toggleClass("up");
});

JsFiddle

修改 根据评论 - 我们可以隐藏当前选定的元素，如下所示：

$("#report tr:odd").addClass("odd");
$("#report tr:not(.odd)").hide();
$("#report tr:first-child").show();

$("#report tr.odd").click(function () {
    var trToToggle = $(this).next("tr");
    $("#report tr:not(.odd)").not(trToToggle).hide();
    $(trToToggle).toggle();
    $(this).find(".arrow").toggleClass("up");
});
