如何使用 JavaScript/jQuery 获取表单数据? [英] How can I get form data with JavaScript/jQuery?

问题描述

是否有一种简单的单行方式来获取表单数据，就像以经典的纯 HTML 方式提交一样?

Is there a simple, one-line way to get the data of a form as it would be if it was to be submitted in the classic HTML-only way?

例如:

<form>
    <input type="radio" name="foo" value="1" checked="checked" />
    <input type="radio" name="foo" value="0" />
    <input name="bar" value="xxx" />
    <select name="this">
        <option value="hi" selected="selected">Hi</option>
        <option value="ho">Ho</option>
</form>

输出:

{
    "foo": "1",
    "bar": "xxx",
    "this": "hi"
}

这样的东西太简单了，因为它没有(正确地)包括文本区域、选择、单选按钮和复选框:

Something like this is too simple, since it does not (correctly) include textareas, selects, radio buttons and checkboxes:

$("#form input").each(function () {
    data[theFieldName] = theFieldValue;
});

推荐答案

$('form').serialize() //this produces: "foo=1&bar=xxx&this=hi"
