我需要您的帮助,如下图所示,我想知道带有所选元素的复选框的 JavaScript 代码,这些复选框应显示在所选元素框下方。谢谢
最佳答案
使用这个 HTML
<div class="taglist">
<label><input type="checkbox" value="2D Animation">2D Animation</label>
<label><input type="checkbox" value="3D Animation">3D Animation</label>
<label><input type="checkbox" value="Animatronics">Animatronics</label>
<label><input type="checkbox" value="Architectural">Architectural</label>
<label><input type="checkbox" value="Cartoon">Cartoon</label>
<label><input type="checkbox" value="Cell Animation">Cell Animation</label>
<label><input type="checkbox" value="Character Animation">Character Animation</label>
<label><input type="checkbox" value="Cut & Paste">Cut & Paste</label>
<label><input type="checkbox" value="Doodle">Doodle</label>
<label><input type="checkbox" value="HDR">HDR</label>
<label><input type="checkbox" value="High Speed">High Speed</label>
<label><input type="checkbox" value="Illustration">Illustration</label>
<label><input type="checkbox" value="Live Action">Live Action</label>
<label><input type="checkbox" value="Macro">Macro</label>
<label><input type="checkbox" value="Motion Design">Motion Design</label>
<label><input type="checkbox" value="Motion Graphics">Motion Graphics</label>
<label><input type="checkbox" value="Moving Installation">Moving Installation</label>
</div>
使用这个 html 代码和这个脚本
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
function updateTextArea() {
var allVals = [];
$('.taglist :checked').each(function(i) {
allVals.push((i!=0?"\r\n":"")+ $(this).val());
});
$('#video0_tags').val(allVals).attr('rows',allVals.length) ;
}
$(function() {
$('.taglist input').click(updateTextArea);
updateTextArea();
});
</script>
