serializeArray() 方法序列化表单元素（类似 .serialize() 方法），返回 JSON 数据结构数据。
html代码：
<form>
<div><input type="text" name="a" value="1" id="a" /></div>
<div><input type="text" name="b" value="2" id="b" /></div>
<div><input type="hidden" name="c" value="3" id="c" /></div>
<div>
<textarea name="d" rows="8" cols="40">4</textarea>
</div>
<div><select name="e">
<option value="5" selected="selected">5</option>
<option value="6">6</option>
<option value="7">7</option>
</select></div>
<div>
<input type="checkbox" name="f" value="8" id="f" />
</div>
<div>
<input type="submit" name="g" value="Submit" id="g" />
</div>
</form>
jquery代码：
$('form').submit(function() {
console.log($(this).serializeArray());
return false;
});
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"
}
]
实际应用例子，通过ajax把表单数据上传给服务器：
var formdataArr = $(form).serializeArray();
var formdata = {};
for (var i = 0; i < formdataArr.length; i++) {
if(formdataArr[i]['name'] == "editorValue"){
continue;
} formdata[formdataArr[i]['name']] = formdataArr[i]['value'];
};
$.ajax({
url: '/cases/submit',
type: 'post',
dataType: 'json',
data: formdata,
success: function(data){ if(data.r == "0"){
bootbox.alert({
message: data.msg || "恭喜，提交保存成功",
callback: function() {
document.location.href = "/cases/showCaseList";
}
});
return false;
}else{
bootbox.alert(data.msg || "抱歉，提交保存失败");
return false;
}
},
error: function(){
bootbox.alert("抱歉，网络繁忙，请稍后再试");
}
});
