我正在尝试选择多选表格中的所有项目。
我的表单运行正常,但是如果我在选择所有项目后取消选择任何项目,则即使单击“全选”也不会再次选择它。但是我可以单独选择它。
下面是我的代码:
$('.selectall').click(function() {
if ($(this).is(':checked')) {
$('.select-all').attr('checked', true);
$('.select-all').closest(".bold").find('input').attr('checked', true);
} else {
$('.select-all').attr('checked', false);
$('.select-all').closest(".bold").find('input').attr('checked', false);
}
});
$('.select-all').click(function() {
if ($(this).is(':checked')) {
$(this).closest(".bold").find('input').attr('checked', true);
} else {
$(this).closest(".bold").find('input').attr('checked', false);
}
});

<form class="needs-validation" novalidate>
<ul class="Items-Select">
<li class="search-items">
<div class="input-group">
<span class="input-group-addon">
<i class="fa fa-search text-info" style="font-size:24px"></i>
</span>
<input type="search" class="form-control" placeholder="Search" onkeyup="mySearch()" id="Search">
<span class="input-group-btn">
<button class="btn btn-default" type="reset">
<i class="fa fa-times-circle-o text-danger" style="font-size:24px"></i>
</button>
</span>
</div>
</li>
<li class="bold">
<label class="checkbox">
<input type="checkbox" class="selectall"> Select all
</label>
</li>
<li class="bold">
<label class="checkbox">
<input type="checkbox" class="select-all"> Group 1
</label>
<span class="caret-container"><b class="caret"></b></span>
<ul class="group" id="groupa">
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="1-1"> Option 1.1
</label>
</li>
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="1-2"> Option 1.2
</label>
</li>
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="1-3"> Option 1.3
</label>
</li>
</ul>
</li>
<li class="bold">
<label class="checkbox">
<input type="checkbox" class="select-all"> Group 2
</label>
<span class="caret-container"><b class="caret"></b></span>
<ul class="group" id="groupb">
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="2-1"> Option 2.1
</label>
</li>
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="2-2"> Option 2.2
</label>
</li>
<li class="dropdown-item">
<label class="checkbox">
<input type="checkbox" value="2-3"> Option 2.3
</label>
</li>
</ul>
</li>
</ul>
</form>
当我直接使用“全选”时,该功能目前仅工作一次,但是不幸的是,当我对所有将不会被“全选”或“组选择”选择的对象执行取消选择时,此操作将无效。
最佳答案
只需使用:
$('.selectall').click(function() {
$('input:checkbox').not(this).prop('checked', this.checked);
});
$('.select-all').click(function() {
$(this).closest(".bold").find('input').prop('checked', this.checked);
});
$('.group').find('input:checkbox').click(function(){
if(!$(this).is(':checked')){
$(this).parents('.group').parent('.bold').find('input.select-all').prop('checked', false);
$('input.selectall').prop('checked', false);
}
});
