我试图显示/隐藏一个div内的表单,但要以多个复选框为条件。如果所有3个都选中,则div内容应出现。如果未选中一个或多个,则div内容应隐藏。
<!DOCTYPE html>
<html lang="en">
<head>
<link href="style/bootstrap.css" rel="stylesheet">
<script src="js/jquery.js"></script>
<script>
if ($('#checkbox1, #checkbox2, #checkbox3').is(:checked)) {
$('#purchaseForm').show();
} else {
$('#purchaseForm').hide();
}
</script>
</head>
<body>
<div class="span6">
I understand that...<br>

<div id="purchaseForm">
[form]
</div>
</div>
<div class="span6">
<input name="checkbox1" id="checkbox1" value="" type="checkbox"><br>
<input name="checkbox2" id="checkbox2" value="" type="checkbox"><br>
<input name="checkbox3" id="checkbox3" value="" type="checkbox"><br>
</div>
</body>
</html>
最佳答案
尝试
jQuery(function(){
var checks = $('#checkbox1, #checkbox2, #checkbox3');
checks.click(function(){
if (checks.filter(':checked').length == checks.length) {
$('#purchaseForm').show();
} else {
$('#purchaseForm').hide();
}
}).triggerHandler('click')
})
