我在表结构中有一些分层数据,如下所示: (例1)
A
A.1
A.1.1
A.1.2
A.2
A.2.1
A.2.2
B
B.1
B.1.1
B.1.2
B.2
B.2.1
B.2.2
我希望能够在每个级别内展开和折叠,例如,如果我点击A.2,它的孩子应该崩溃:(示例2)
A
A.1
A.1.1
A.1.2
A.2
B
B.1
B.1.1
B.1.2
B.2
B.2.1
B.2.2
如果我点击A,它的所有孩子都应该崩溃:(例3)
A
B
B.1
B.1.1
B.1.2
B.2
B.2.1
B.2.2
如果我再次展开A,A.2仍应保持折叠状态(儿童隐藏)(例4)
A
A.1
A.1.1
A.1.2
A.2
B
B.1
B.1.1
B.1.2
B.2
B.2.1
B.2.2
我尝试过来自http://jsfiddle.net/y4Mdy/1124/的代码示例 - 但不处理三级层次结构。 $(this).nextUntil似乎很好用,但是当下一个tr是父行时,它会折叠到下一个子行。此外,如果我折叠第二级然后折叠父级,则隐藏第二级,但第三级显示:
A
A.1.1
A.1.2
B
B.1
B.1.1
B.1.2
B.2
B.2.1
B.2.2
我也尝试了http://jsfiddle.net/icc97/XNkbE/ - 但是当点击父级时,子级别不会回到折叠状态(类似于上面的示例4)
有人可以帮忙吗?
提前致谢。

此解决方案应处理任意数量的级别。
我原来的jsfiddle是here。我将比这个答案更频繁地更新它。

答案 1 :(得分:0)
由于您只处理嵌套的table
,因此您可以使用以下内容:
CSS:
tbody.collapsed {
display: none;
}
JS:
$('thead').click(function(){
$(this).siblings('tbody').toggleClass('collapsed');
});
我使用thead
和tbody
来使用语义。
答案 2 :(得分:0)
如果单击第一个级别的元素,则将隐藏第2层和第3层的所有可见元素。如果第一个级别的元素已被隐藏,则使第2层的元素再次可见。
toggleElement = function(context) {
let current = context.parentElement
if (current.className == 'level1') {
toggleLevel1(current)
} else if (current.className == 'level2') {
toggleLevel2(current)
}
};
toggleLevel1 = function(current) {
let nextSibling = current.nextElementSibling;
while (nextSibling && nextSibling.className == 'level2') {
nextSibling.hidden = nextSibling.hidden ? false : true
nextSibling = nextSibling.nextElementSibling
while (nextSibling && nextSibling.className == 'level3') {
if (!nextSibling.hidden) {
nextSibling.hidden = nextSibling.hidden ? false : true
}
nextSibling = nextSibling.nextElementSibling
}
}
};
toggleLevel2 = function(current) {
let nextSibling = current.nextElementSibling;
while (nextSibling && nextSibling.className == 'level3') {
nextSibling.hidden = nextSibling.hidden ? false : true
nextSibling = nextSibling.nextElementSibling
}
};
