</html>下面是获取所有表单字段值的代码：
$("#hidAll").append($("#preview_form :input").map(function () {
if ($(this).val() != 'Submit') {
if ($(this).is('select')) {
var aa = $(this).children('option').map(function () {
return $(this).val();
}).get().join("|");
return $(this).attr('name') + '|' + aa;
} else if ($(this).is('input:checkbox')) {
return $(this).attr('name').substring(0, $(this).attr('name').length - 2) + '|' + $(this).val();
} else {
return $(this).attr('name') + '|' + $(this).val();
}
}
}).get().join(","));
alert($("#hidAll").html());从这里我得到了如下的输出值：
textfield_1|dgdfg,
checkboxgroup_1|Option 1,
checkboxgroup_1|Option 2,
checkboxgroup_1|Option 3,
radiobutton_1|Option 1,
radiobutton_1|Option 2,
radiobutton_1|Option 3,
dropdown_1|Option 1!Option 2!Option 3我希望输出如下所示：
textfield_1|dgdfg,
checkboxgroup_1|Option 1!Option 2!Option 3,
radiobutton_1|Option 1!Option 2!Option 3,
dropdown_1|Option 1!Option 2!Option 3回答 8

您可以使用JQuery的serialize()函数：
var datastring = $("#preview_form").serialize();
$.ajax({
type: "POST",
url: "your url.php",
data: datastring,
success: function(data) {
alert('Data send');
}
});并在PHP中阅读：
echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........并获取*data-*来标记HTML5，您可以看到这个示例：
<div id="texto" data-author="Ricardo Miranda" data-date="2012-06-21">
<h4>Lorem ipsum</h4>
<p>
Lorem ipsum dolor sit amet, ius integre eligendi et,
sea ut expetendis conclusionemque,
mel at ornatus invenire. His ad moderatius definiebas omittantur,
liber saepe albucius sea cu.
Audire tamquam dolores vis ne, mediocrem consulatu eum ex.
Duo te agam saepe convenire, et fugit iisque his.
</p>
<script type="text/javascript">
$(function() {
alert("The text is write " + $('#texto').data('author'));
});
和
<div id="texto" data-author='{"nombre":"Ricardo","apellido":"Miranda"}' data-date="2012-06-21">
...
</div>
<script type="text/javascript">
$(function() {
alert("The text is write " + $('#texto').data('author').apellido + ", " +
('#texto').data('author').nombre);
});
</script>Stack Overflow用户

jQuery有一个非常有用的函数，叫做serialize。
演示：http://jsfiddle.net/55xnJ/2/
//Just type:
$("#preview_form").serialize();
//to get result:
single=Single&multiple=Multiple&multiple=Multiple3&check=check2&radio=radio1Stack Overflow用户

尝试将表单输入文本值获取到JavaScript对象...
var fieldPair = {};
$("#form :input").each(function() {
if($(this).attr("name").length > 0) {
fieldPair[$(this).attr("name")] = $(this).val();
}
});
console.log(fieldPair);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
