我有 4 个按钮，我希望能够检测到哪个按钮被单击或按 Tab 键并用空格键选择。但我无法让按钮发出警报。有人可以帮我检测选择了哪个按钮吗？
<div id="searchoptions">
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="accountNumber" name="accountNumber" value="accountNumber">PROPERTY ID</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="name" name="name" value="name">OWNER NAME</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="location" name="location" value="location">PROPERTY ADDRESS</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="billingAddress" name="billingAddress" value="billingAddress">BILLING ADDRESS</button>
</div>
</div>
$(document).on('click', '#accountNumber, #name, #location, #billingAddress,', function() {
var value = $(this).val();
alert(value);
if (value === "accountNumber") {
alert("accountNumber");
} else if (value === "name"){
alert("name");
} else if (value === "location"){
alert("location");
} else if (value === "billingAddress"){
alert("billingAddress");
}
});
也尝试过:
$('input[type=button]').each(function(){
var value = $(this).val();
if (value === "accountNumber") {
alert("accountNumber");
} else if (value === "name"){
alert("name");
} else if (value === "location"){
alert("location");
} else if (value === "billingAddress"){
alert("billingAddress");
}
});
最佳答案
删除选择器字符串处的尾随逗号 ,。您还可以使用选择器#searchoptions 按钮
$(document).on('click', '#searchoptions button', function() {
console.log(this.value)
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="searchoptions">
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="accountNumber" name="accountNumber" value="accountNumber">PROPERTY ID</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="name" name="name" value="name">OWNER NAME</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="location" name="location" value="location">PROPERTY ADDRESS</button>
</div>
<div class="col-sm-3">
<button type="button" class="btn-u btn-default input-sm margin-bottom-10" id="billingAddress" name="billingAddress" value="billingAddress">BILLING ADDRESS</button>
</div>
