我有这个html,我需要根据一个参数选择一个特定的复选框。让我们说我的参数是15,所以我需要找到data-id = 15,然后获取关联的复选框并以编程方式检查此复选框。我试图使用jquery,但我对此并不十分熟悉。我需要从div开始搜索id =" org_container_1"。
<div class="department-container" id="org_container_1">
<div class="row department-row" data-typeid="1" data-id="14">
<label>
<input type="checkbox">
<span class="department-item">Org1</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="15">
<label>
<input type="checkbox">
<span class="department-item">Org2</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="16">
<label>
<input type="checkbox">
<span class="department-item">Org3</span>
</label>
</div>

您可以使用选择器使用数据属性选择器[data-attribute-name=data-attribute-value]
选择具有data-id的div。然后选中input[type=checkbox]
复选框,并使用.prop()
功能进行检查。
$().ready(function() {
$('div[data-id=15] input[type=checkbox]').prop('checked', true);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="department-container" id="org_container_1">
<div class="row department-row" data-typeid="1" data-id="14">
<label>
<input type="checkbox">
<span class="department-item">Org1</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="15">
<label>
<input type="checkbox">
<span class="department-item">Org2</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="16">
<label>
<input type="checkbox">
<span class="department-item">Org3</span>
</label>
</div>

所以你想在这里使用2件事。第一个是正确的jquery选择器,第二个是设置#attr('checked', true)
:
$('div[data-id="' + id + '"] input[type=checkbox').attr('checked', true)
(你当然希望将它包装在一个函数中,但既然你已经提供了你的js看起来像什么,我没有任何关于你在哪里调用它的上下文)

另一种选择:
var param='15';
$('.department-container .department-row').each(function(){
if($(this).attr('data-id')==param){
$('input', this).attr('checked','checked');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<div class="department-container" id="org_container_1">
<div class="row department-row" data-typeid="1" data-id="14">
<label>
<input type="checkbox">
<span class="department-item">Org1</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="15">
<label>
<input type="checkbox">
<span class="department-item">Org2</span>
</label>
</div>
<div class="row department-row" data-typeid="1" data-id="16">
<label>
<input type="checkbox">
<span class="department-item">Org3</span>
</label>
</div>
