此方法将表单元素数组序列化为适合 Ajax 请求的字符串（默认行为），或者如果可选的 getHash 计算结果为真，则为对象哈希，其中键是表单控件名称，值是数据。
序列化表单的首选方法是Form.serialize。但是，使用serializeElements ，您可以序列化您选择的特定输入元素。
语法
Form.serializeElements(elements [,getHash = false]);返回值
它返回一个字符串对象。
例子
考虑以下示例：
<html>
<head>
<title>Prototype examples</title>
<script type = "text/javascript" src = "/javascript/prototype.js"></script>
<script>
function showResult() {
var form = $('example');
var arr = form.getInputs('text');
var element = Form.serializeElements( arr );
alert("Serialized String : " + element.inspect());
}
</script>
</head>
<body>
<p>Click the button to see the result.</p>
<br />
<form id = "example" action = "#" onsubmit = "return false">
<fieldset>
<legend>User info</legend>
<div>
<label for = "username">Username:</label>
<input name = "username" id = "username" value = "Sulien" type = "text">
</div>
<div><label for = "age">Age:</label>
<input name = "age" id = "age" value = "23" size = "3" type = "text">
</div>
<div>
<label for = "hobbies">Your hobbies are:</label>
<select name = "hobbies" id = "hobbies" multiple = "multiple">
<option>coding</option>
<option>swimming</option>
<option>hiking</option>
<option>drawing</option>
</select>
</div>
</fieldset>
</form>
<br />
<input type = "button" value = "Result" onclick = "showResult();"/>
</body>
</html>大家可以预览试试吧！
