你也可以使用FormData对象;FormData对象允许您编译一组键/值对，以便使用XMLHttpRequest发送。它主要用于发送表单数据，但也可以独立于表单用于传输键控数据。

        var formElement = document.getElementById("myform_id");
        var formData = new FormData(formElement);
        console.log(formData);

我已经包括答案，也给回所需的对象。

function getFormData(form) {
var rawJson = form.serializeArray();
var model = {};

$.map(rawJson, function (n, i) {
    model[n['name']] = n['value'];
});

return model;
}

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

除此之外，你可能想看看serialize();

document.querySelector('form').addEventListener('submit', (e) => {
  const formData = new FormData(e.target);
  // Now you can use formData.get('foo'), for example.
  // Don't forget e.preventDefault() if you want to stop normal form .submission
});

这是一个吹毛求疵的答案，但让我解释为什么这是一个更好的解决方案:

We're properly handling a form submit rather than a button press. Some people like to push enter on fields. Some people use alternative input devices such as speech input or other accessibility devices. Handle the form submit and you correctly solve it for everyone. We're digging into the form data for the actual form that was submitted. If you change your form selector later, you don't have to change the selectors for all the fields. Furthermore, you might have several forms with the same input names. No need to disambiguate with excessive IDs and what not, just track the inputs based on the form that was submitted. This also enables you to use a single event handler for multiple forms if that is appropriate for your situation. The FormData interface is fairly new, but is well supported by browsers. It's a great way to build that data collection to get the real values of what's in the form. Without it, you're going to have to loop through all the elements (such as with form.elements) and figure out what's checked, what isn't, what the values are, etc. Totally possible if you need old browser support, but the FormData interface is simpler. I'm using ES6 here... not a requirement by any means, so change it back to be ES5 compatible if you need old browser support.

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

demo

你可以使用这个函数从表单中获取一个对象或JSON。

使用它:

var object = formService.getObjectFormFields（“#idform”）;

function getObjectFormFields(formSelector) { /// <summary>Função que retorna objeto com base nas propriedades name dos elementos do formulário.</summary> /// <param name="formSelector" type="String">Seletor do formulário</param> var form = $(formSelector); var result = {}; var arrayAuxiliar = []; form.find(":input:text").each(function (index, element) { var name = $(element).attr('name'); var value = $(element).val(); result[name] = value; }); form.find(":input[type=hidden]").each(function (index, element) { var name = $(element).attr('name'); var value = $(element).val(); result[name] = value; }); form.find(":input:checked").each(function (index, element) { var name; var value; if ($(this).attr("type") == "radio") { name = $(element).attr('name'); value = $(element).val(); result[name] = value; } else if ($(this).attr("type") == "checkbox") { name = $(element).attr('name'); value = $(element).val(); if (result[name]) { if (Array.isArray(result[name])) { result[name].push(value); } else { var aux = result[name]; result[name] = []; result[name].push(aux); result[name].push(value); } } else { result[name] = []; result[name].push(value); } } }); form.find("select option:selected").each(function (index, element) { var name = $(element).parent().attr('name'); var value = $(element).val(); result[name] = value; }); arrayAuxiliar = []; form.find("checkbox:checked").each(function (index, element) { var name = $(element).attr('name'); var value = $(element).val(); result[name] = arrayAuxiliar.push(value); }); form.find("textarea").each(function (index, element) { var name = $(element).attr('name'); var value = $(element).val(); result[name] = value; }); return result; }
