我在樹視圖中添加了復選框，但節點（父或子...）與添加的復選框之間沒有關系
我想要當我單擊節點或在輸入時選中復選框并同時打開該節點的子節點串列，
如果我再次單擊節點（父節點或子節點...）或輸入，我取消選中輸入并關閉該節點的子節點串列
這是我的代碼
$(function () {
$('.tree li:has(ul)').addClass('parent_li').find(' > span').attr('title', 'Collapse this branch');
var extra = $(".tree li.parent_li > span")
.parent("li.parent_li")
.find(" > ul > li");
extra.hide("fast");
$('.tree li.parent_li > span').on('click', function (e) {
var children = $(this).parent('li.parent_li').find(' > ul > li');
if (children.is(":visible")) {
children.hide('fast');
$(this).attr('title', 'Expand this branch').find(' > i').addClass('icon-plus-sign').removeClass('icon-minus-sign');
} else {
children.show('fast');
$(this).attr('title', 'Collapse this branch').find(' > i').addClass('icon-minus-sign').removeClass('icon-plus-sign');
}
e.stopPropagation();

uj5u.com熱心網友回復：
添加$(this).find("input").removeAttr("checked")和$(this).find("input").prop("checked", "true")設定和洗掉選中的屬性：
$(".tree li.parent_li > span").on("click", function (e) {
var children = $(this).parent("li.parent_li").find(" > ul > li");
if (children.is(":visible")) {
$(this).find("input").removeAttr("checked");/*----------------*/
children.hide("fast");
$(this)
.attr("title", "Expand this branch")
.find(" > i")
.addClass("icon-plus-sign")
.removeClass("icon-minus-sign");
} else {
$(this).find("input").prop("checked", "true");/*----------------*/
children.show("fast");
$(this)
.attr("title", "Collapse this branch")
.find(" > i")
.addClass("icon-minus-sign")
.removeClass("icon-plus-sign");
}
e.stopPropagation();
});
