使用Jquery检查/取消选中父/子复选框 [英] Check/Uncheck Parent/Child Checkboxes using Jquery
问题描述
我真的不熟悉jquery或javascript,我需要一个快速解决我的问题,这就是为什么im发布在这里。下面是一个示例HTML代码段:
< ul>
< li>< input type =checkbox/>管理
< ul>
< li>< input type =checkbox/> President
< ul>
< li>< input type =checkbox/>管理员1
< ul>
< li>< input type =checkbox/>助理经理1< / li>
< li>< input type =checkbox/>助理经理2< / li>
< li>< input type =checkbox/>助理经理3< / li>
< / ul>
< / li>
< li>< input type =checkbox/>管理员2< / li>
< li>< input type =checkbox/>管理员3< / li>
< / ul>
< / li>
< li>< input type =checkbox/>副总裁
< ul>
< li>< input type =checkbox/>管理员4< / li>
< li>< input type =checkbox/>管理员5< / li&
< li>< input type =checkbox/>管理员6< / li>
< / ul>
< / li>
< / ul>
< / li>
< / ul>
我想做的是检查管理时检查一切。如果我不支持总统,那么,他的父母也应该与他的孩子一起离开,只有副总统和他的孩子被检查。
同样,如果我检查经理1,那么他的孩子也应该检查。但是如果我取消选中助理经理1,那么经理1也应该取消选中,只留下Asst。已选中经理2和3。
请注意,此列表是动态的。
请参阅: DEMO
$('li:checkbox')。on('click',function(){
var $ chk = $(this),
$ li = $ chk.closest('li'),
$ ul,$ parent;
if($ li.has('ul')){
$ li.find(':checkbox' ).not(this).prop('checked',this.checked)
}
do {
$ ul = $ li.parent();
$ parent = $ ul.siblings(':checkbox');
if($ chk.is(':checked')){
$ parent.prop('checked',$ ul.has(':checkbox: not(:checked)')。length == 0)
} else {
$ parent.prop('checked',false)
}
$ chk =
$ li = $ chk.closest('li');
} while($ ul.is(':not(.someclass)'));
});
I am not really that familiar with jquery or javascript and I need a quick solution to my problem that is why im posting it here. Below is a sample html snippet:
<ul>
<li><input type="checkbox" />Administration
<ul>
<li><input type="checkbox" />President
<ul>
<li><input type="checkbox" />Manager 1
<ul>
<li><input type="checkbox" />Assistant Manager 1</li>
<li><input type="checkbox" />Assistant Manager 2</li>
<li><input type="checkbox" />Assistant Manager 3</li>
</ul>
</li>
<li><input type="checkbox" />Manager 2</li>
<li><input type="checkbox" />Manager 3</li>
</ul>
</li>
<li><input type="checkbox" />Vice President
<ul>
<li><input type="checkbox" />Manager 4</li>
<li><input type="checkbox" />Manager 5</li>
<li><input type="checkbox" />Manager 6</li>
</ul>
</li>
</ul>
</li>
</ul>
What I would like to do is to check everything when Administration is checked. If I uncheck President, then, his parent/s should be unchecked also together with his children leaving only the Vice President and his children checked. Similarly, if I check Manager 1 then his children should be checked also. But if I uncheck Assistant Manager 1 then Manager 1 should also be unchecked leaving only Asst. Manager 2 and 3 checked.
Take note that this list is dynamic. Meaning a child can have more children and so on.
Thanks in advance!
See this: DEMO
$('li :checkbox').on('click', function () {
var $chk = $(this),
$li = $chk.closest('li'),
$ul, $parent;
if ($li.has('ul')) {
$li.find(':checkbox').not(this).prop('checked', this.checked)
}
do {
$ul = $li.parent();
$parent = $ul.siblings(':checkbox');
if ($chk.is(':checked')) {
$parent.prop('checked', $ul.has(':checkbox:not(:checked)').length == 0)
} else {
$parent.prop('checked', false)
}
$chk = $parent;
$li = $chk.closest('li');
} while ($ul.is(':not(.someclass)'));
});
