javascript - 展开/折叠表格行

Question

我想要一张可以展开或折叠的表格。我的要求是当我点击表格行然后隐藏行显示或者当我点击其他表格行然后上一个打开的行隐藏或显示相对隐藏行。我发现一个 jquery jxpand 非常适合我，它显示隐藏的行但是当我单击其他行时，以前的隐藏数据保持打开状态而不是隐藏我想要以前的隐藏或显示新的相关行隐藏数据。我的代码片段如下

$(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;}

如果查看英国隐藏数据然后打开加拿大隐藏数据，英国打开的数据将再次隐藏，加拿大数据将打开

Answer 1

只需在点击函数中添加$("#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

编辑根据评论——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");
});
