我想从已检查的输入中获取标签.text()
。实际上,我的代码检查是否检查了输入,然后从具有相同类的每个<li>
获取标签,而不仅仅是已检查的标签。我怎样才能实现这一目标?我认为我应该使用.parent()或.child()属性,但我不知道如何。
我尝试使用alert($('#myId input').parent('label').text());
,但没有成功。
Codepen https://codepen.io/Qasph/pen/LyNJev?editors=1010
$('#result').click(function() {
// If an input is checked
if ($('#myId input').is(':checked')) {
// Get text from label parent
console.log($('#myId label').text());
} else {}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myId">
<ul>
<!-- First class -->
<li class="myFirstClass"><label><input type="checkbox" value="3">1 - First class</label></li>
<li class="myFirstClass"><label><input type="checkbox" value="6">2 - First class</label></li>
<!-- Second class -->
<li class="mySecondClass"><label><input type="checkbox" value="3">1bis - Second class</label></li>
<li class="mySecondClass"><label><input type="checkbox" value="6">2bis - Second class</label></li>
</ul>
</div>
<button id="result">Result</button>

要实现此目的,您可以使用map()
遍历所有:checked
复选框,并构建父label
元素的文本值数组。试试这个:
$('#result').click(function() {
var labels = $('#myId :checked').map(function() {
return $(this).closest('label').text();
}).get();
console.log(labels);
});

<li class="myFirstClass"><label><input type="checkbox" value="3">1 - First class</label></li>
<li class="myFirstClass"><label><input type="checkbox" value="6">2 - First class</label></li>
<li class="mySecondClass"><label><input type="checkbox" value="3">1bis - Second class</label></li>
<li class="mySecondClass"><label><input type="checkbox" value="6">2bis - Second class</label></li>
</ul>
</div>
<button id="result">Result</button>

$('#result').click(function() {
// If an input is checked
$('#myId input').each(function() {
if($(this).is(":checked")) {
console.log($(this).parent().text());
}
})
});
Rory回答的替代方案。如果检查了每个输入,只需检查它们(更容易阅读和理解,但完全相同)。

循环或映射选中的输入并抓取父标签或最近标签
$('#result').click(function() {
// If an input is checked
var result = [];
$('#myId input:checked').each(function() { // or map
result.push($(this).parent().text())
});
console.log(result);
});

如果您只需要选中复选框标签的文本,我只会要求它们;)
$('#result').click(function() {
var $checkedInputs = $('input:checked');
if ($checkedInputs.length !== -1) {
$checkedInputs.each(function (i) {
alert($checkedInputs.eq(i).parent().text());
});
}
});
