How to get form data as a object in jquery
提问by kevin
I have tried jQuery('#form_id').serialize(). This returns only the form data as a url encoded string. Is it possible to get the form data as an object?
我试过了jQuery('#form_id').serialize()。这仅将表单数据作为 url 编码字符串返回。是否可以将表单数据作为对象获取？

Have you tried "serializeArray"? That gives you an array of names and values. You could turn that into an object if you wanted to:
你试过“serializeArray”吗？这为您提供了一组名称和值。如果你想，你可以把它变成一个对象：
var paramObj = {};
$.each($('#myForm').serializeArray(), function(_, kv) {
paramObj[kv.name] = kv.value;
});
(I'll have to check again to see what jQuery does with arrays; I thinkit encodes them as Javascript array values, but I'm not 100% sure.)
（我将不得不再次检查以查看 jQuery 对数组做了什么；我认为它将它们编码为 Javascript 数组值，但我不是 100% 确定。）
editah no, it doesn't set up multi-valued parameters as arrays - you get repeats of the same name. Thus, the make-an-object code should look like this:
编辑啊不，它不会将多值参数设置为数组 - 你会得到同名的重复。因此，make-an-object 代码应该如下所示：
var paramObj = {};
$.each($('#myForm').serializeArray(), function(_, kv) {
if (paramObj.hasOwnProperty(kv.name)) {
paramObj[kv.name] = $.makeArray(paramObj[kv.name]);
paramObj[kv.name].push(kv.value);
}
else {
paramObj[kv.name] = kv.value;
}
});
(or something like that; could probably be squeezed a little.)
（或类似的东西；可能会被挤压一点。）

You may take a look at the serializeArrayfunction:
你可以看看serializeArray函数：
$('#form_id').serializeArray()
