Php 单选按钮组，更改事件？

我有一组由cakephp生成的单选按钮

<input type="radio" name="data[hexInput]" id="HexInput1" value="h1">
<input type="radio" name="data[hexInput]" id="HexInput2" value="h2">
<input type="radio" name="data[hexInput]" id="HexInput3" value="h3">

只需为每个单选按钮创建一个onclick。你可以这样做：

function update(val) {
    alert("Radio button changed to " + val);
}

<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput1" value="h1">
<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput2" value="h2">
<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput3" value="h3">

然后将其连接到每个输入，如下所示：

function update(val) {
    alert("Radio button changed to " + val);
}

<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput1" value="h1">
<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput2" value="h2">
<input onclick="update(this.value);" type="radio" name="data[hexInput]" id="HexInput3" value="h3">
