这篇文章主要介绍了serializeArray()方法怎么用,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。

.serializeArray()方法使用标准的W3C"successful controls"的标准来检测哪些元素应当包括在内。被禁用的元素不会被包括在内。并且,元素必须含有 name 属性。此外,提交按钮的值也不会被序列化。文件选择元素的数据也不会被序列化。

.serializeArray() 方法可以对单独选择的表单元素对象进行操作, 比如 , , 和 。还有个更方便的方法是,直接使用 标签来进行序列化操作:

$('form').submit(function() {

console.log($(this).serializeArray());

return false;

});

这将产生以下数据结构(浏览器提供的console.log):

[

{

name: "a",

value: "1"

},

{

name: "b",

value: "2"

},

{

name: "c",

value: "3"

},

{

name: "d",

value: "4"

},

{

name: "e",

value: "5"

}

]

例子:

从表单获取值,遍历并且显示他们

body, select { font-size:14px; }

form { margin:5px; }

p { color:red; margin:5px; }

b { color:blue; }

Results:

Single

Single2

Multiple

Multiple2

Multiple3

check1

check2

radio1

radio2

function showValues() {

var fields = $(":input").serializeArray();

$("#results").empty();

jQuery.each(fields, function(i, field){

$("#results").append(field.value + " ");

});

}

$(":checkbox, :radio").click(showValues);

$("select").change(showValues);

showValues();
