jQuery serializeArray()键值对

Question

我在序列化表单时遇到了一些问题

<form>
    <input type="text" name="name1" value="value1"/>
    <input type="text" name="name2" value="value2"/>
</form>

$(form).serializeArray()

将返回[{name:"name1",value:"value1"},{name:"name2",value:"value2"}]对。

是否可以在表单中获得输出

{name1:value1,name2:value2}

这样它们就更容易处理了？

Answer 1

var result = { };
$.each($('form').serializeArray(), function() {
    result[this.name] = this.value;
});

// at this stage the result object will look as expected so you could use it
alert('name1 = ' + result.name1 + ', name2 = ' + result.name2);

Live demo.

Answer 2

$.fn.serializeObject = function () {
    var o = {};
    var a = this.serializeArray();
    $.each(a, function () {
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }      
            o[this.name].push(this.value || '');
        } else {
            o[this.name] = this.value || '';
        }
    });
    return o;
};

Answer 3

如果您的表单没有复选框或单选按钮，接受的答案效果很好。由于这些组都具有相同的name属性，因此需要在对象内创建一个数组值。所以对于像这样的html：

<input type="checkbox" value="1" name="the-checkbox">
<input type="checkbox" value="2" name="the-checkbox">
<input type="checkbox" value="3" name="the-checkbox">

你会得到：

{the-checkbox:['1', '2', '3']}

一小段This代码可以很好地处理所有事情。

// Whereas .serializeArray() serializes a form into an array, .serializeObject()
// serializes a form into an (arguably more useful) object.

(function($,undefined){
  '$:nomunge'; // Used by YUI compressor.
  
  $.fn.serializeObject = function(){
    var obj = {};
    
    $.each( this.serializeArray(), function(i,o){
      var n = o.name,
        v = o.value;
        
        obj[n] = obj[n] === undefined ? v
          : $.isArray( obj[n] ) ? obj[n].concat( v )
          : [ obj[n], v ];
    });
    
    return obj;
  };
  
})(jQuery);

用法

$(form).serializeObject();
