jQuery 仅序列化 div 中的元素

jQuery to serialize only elements within a div

提问by BrokeMyLegBiking

I would like to get the same effect as jQuery.serialize()but I would like to return only the child elments of a given div.

我想获得相同的效果，jQuery.serialize()但我只想返回给定div.

Sample result :

示例结果：

single=Single2&multiple=Multiple&radio=radio1

No problem. Just use the following. This will behave exactly like serializing a form but using a div's content instead.

没问题。只需使用以下内容。这将与序列化表单完全一样，但使用 div 的内容。

$('#divId :input').serialize();

You can improve the speed of your code if you restrict the items jQuery will look at.

如果您限制 jQuery 将查看的项目，则可以提高代码的速度。

Use the selector :inputinstead of *to achieve it.

使用选择器:input而不是*来实现它。

$('#divId :input').serialize()

This will make your code faster because the list of items is shorter.

这将使您的代码更快，因为项目列表更短。

serializeall the form-elements within a div.

serialize中的所有表单元素div。

You could do that by targeting the div #target-div-idinside your formusing :

您可以通过#target-div-id在formusing 中定位 div 来做到这一点：

$('#target-div-id').find('select, textarea, input').serialize();

The function I use currently:

我目前使用的功能：

/**
 * Serializes form or any other element with jQuery.serialize
 * @param el
 */
serialize: function(el) {
    var serialized = $(el).serialize();
    if (!serialized) // not a form
        serialized = $(el).
          find('input[name],select[name],textarea[name]').serialize();
    return serialized;
}

$('#divId').find('input').serialize()

What about my solution:

我的解决方案呢：

function serializeDiv( $div, serialize_method )
{
    // Accepts 'serialize', 'serializeArray'; Implicit 'serialize'
    serialize_method = serialize_method || 'serialize';

    // Unique selector for wrapper forms
    var inner_wrapper_class = 'any_unique_class_for_wrapped_content';

    // Wrap content with a form
    $div.wrapInner( "<form class='"+inner_wrapper_class+"'></form>" );

    // Serialize inputs
    var result = $('.'+inner_wrapper_class, $div)[serialize_method]();

    // Eliminate newly created form
    $('.script_wrap_inner_div_form', $div).contents().unwrap();

    // Return result
    return result;
}

/* USE: */

// For: $('#div').serialize()
serializeDiv($('#div')); /* or */ serializeDiv($('#div'), 'serialize');

// For: $('#div').serializeArray()
serializeDiv($('#div'), 'serializeArray');

function serializeDiv( $div, serialize_method )
{
 // Accepts 'serialize', 'serializeArray'; Implicit 'serialize'
 serialize_method = serialize_method || 'serialize';

 // Unique selector for wrapper forms
 var inner_wrapper_class = 'any_unique_class_for_wrapped_content';

 // Wrap content with a form
 $div.wrapInner( "<form class='"+inner_wrapper_class+"'></form>" );

 // Serialize inputs
 var result = $('.'+inner_wrapper_class, $div)[serialize_method]();

 // Eliminate newly created form
 $('.script_wrap_inner_div_form', $div).contents().unwrap();

 // Return result
 return result;
}

/* USE: */

var r = serializeDiv($('#div')); /* or serializeDiv($('#div'), 'serialize'); */
console.log("For: $('#div').serialize()");
console.log(r);

var r = serializeDiv($('#div'), 'serializeArray');
console.log("For: $('#div').serializeArray()");
console.log(r);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div">
  <input name="input1" value="input1_value">
  <textarea name="textarea1">textarea_value</textarea>
</div>

If those elements have a common class name, one may also use this:

如果这些元素有一个共同的类名，你也可以使用这个：

$('#your_div .your_classname').serialize()

This way you can avoid selection of buttons, which will be selected using the jQuery selector :input. Though this can also be avoided by using $('#your_div :input:not(:button)').serialize();

通过这种方式，您可以避免选择按钮，这些按钮将使用 jQuery 选择器进行选择:input。虽然这也可以通过使用来避免$('#your_div :input:not(:button)').serialize();

$('#divId > input, #divId > select, #divId > textarea').serialize();
