Here the code which will get all form field values:

这里的代码将获取所有表单字段值:

 $("#hidAll").append($("#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());

From this i am getting the output value as followes:

由此我得到如下输出值:

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

i want the out as following:

我想要如下:

 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

You can use a serialize() function of JQuery:

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');
            }
        });

And read in PHP:

并在 PHP 中阅读:

echo $_POST['datastring']['dialog_box_textarea_1'];
echo $_POST['datastring']['radiobutton_1'];
........

And get ***data-**** to tag HTML5 you can see this example:

并获取 ***data-**** 来标记 HTML5 你可以看到这个例子:

<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'));
});

And

<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>

I know you're using jQuery but for those who want a pure Javascriptsolution:

我知道您正在使用 jQuery,但对于那些想要纯 Javascript解决方案的人:

// Serialize form fields as URI argument/HTTP POST data
function serializeForm(form) {
    var kvpairs = [];
    for ( var i = 0; i < form.elements.length; i++ ) {
        var e = form.elements[i];
        if(!e.name || !e.value) continue; // Shortcut, may not be suitable for values = 0 (considered as false)
        switch (e.type) {
            case 'text':
            case 'textarea':
            case 'password':
            case 'hidden':
                kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            case 'radio':
            case 'checkbox':
                if (e.checked) kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
                break;
            /*  To be implemented if needed:
            case 'select-one':
                ... document.forms[x].elements[y].options[0].selected ...
                break;
            case 'select-multiple':
                for (z = 0; z < document.forms[x].elements[y].options.length; z++) {
                    ... document.forms[x].elements[y].options[z].selected ...
                } */
                break;
        }
    }
    return kvpairs.join("&");
}

jQuery 有一个非常有用的函数叫做serialize

Demo: http://jsfiddle.net/55xnJ/2/

演示:http: //jsfiddle.net/55xnJ/2/

Try this for getting form input text value to JavaScript object...

试试这个以获取表单输入文本值到 JavaScript 对象...

var fieldPair = {};
$("#form :input").each(function() {
    if($(this).attr("name").length > 0) {
        fieldPair[$(this).attr("name")] = $(this).val();
    }
});

console.log(fieldPair);

Add this on to the end of it:

将其添加到它的末尾:

var array = $("#hidAll").html();

x = array.split(',');
key=s="";
for (i=0; i<x.length; i++) {
  oldkey = key;
  key = x[i].split('|')[0];
  if (oldkey==key) s+='!';
  else s+=',\n'+key+'|';
  s+=x[i].split('|')[1];
}
s = s.substring(1);
$('#hidAll').html(a);

回答by Hyman LI

If you want to use $(formName).serializeArray() or $(formName).serialize(), you must add name='inputName'on your input element. or will not work!

如果您想使用 $(formName).serializeArray() 或 $(formName).serialize(),您必须添加name='inputName'您的输入元素。否则将无法工作!

回答by Aryeh Beitz

I needed to get the form data as some sort of object. I used this:

我需要将表单数据作为某种对象获取。我用过这个:

$('#preview_form').serializeArray().reduce((function(acc, val) {
  acc[val.name.replace('[', '_').replace(']', '')] = val.value;
  return acc;
}), {});

回答by Frahim

The answer already been accepted, I just write a short technique for the same purpose.

答案已经被接受,我只是为了同样的目的写了一个简短的技术。

var fieldPair = '';
$(":input").each(function(){
fieldPair += $(this).attr("name") + ':' + $(this).val() + ';';
});

console.log(fieldPair);

if you want get all values from form in simple array you may be do something like this.

如果你想从简单数组中的表单中获取所有值,你可能会做这样的事情。

function getValues(form) {
    var listvalues = new Array();
    var datastring = $("#" + form).serializeArray();
    var data = "{";
    for (var x = 0; x < datastring.length; x++) {
        if (data == "{") {
            data += "\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
        else {
            data += ",\"" + datastring[x].name + "\": \"" + datastring[x].value + "\"";
        }
    }
    data += "}";
    data = JSON.parse(data);
    listvalues.push(data);
    return listvalues;
};
