根据单击的按钮获取表单内的输入值

I've got the following form:

我有以下表格:

<div>
  <form name="ajaxformname" id="ajaxform" action="/request" method="POST">
    AJAX:
    <input id="btn1" name="feeling" type="submit" value="Fine">
    <input id="btn2" name="feeling" type="submit" value="Neutral">
    <input id="btn3" name="feeling" type="submit" value="Bad">
  </form>
</div>

which should be posted to a server via ajax.

应该通过ajax发布到服务器。

Here is the associated javascript:

这是相关的javascript:

$('#ajaxform').submit(function (event) {
    event.preventDefault();
        var form = $(this); 
        var action = form.attr("action"), 
            method = form.attr("method"),
            data = form.attr("value");

    $.ajax({
        url: "/request",
        type: method,
        data: data
    });

Now - depending on which of the three buttons has been clicked - I want their values to be posted to the server. But form.attr("value") just gives me the value of the form but not of the input field.

现在 - 根据点击的三个按钮中的哪一个 - 我希望将它们的值发布到服务器。但是form.attr(“value”)只给出了表单的值而不是输入字段的值。

Any suggestions? A solution would be to create the different forms but that doesn't seems to be DRY ...

有什么建议?一个解决方案是创建不同的形式,但似乎并不干......

First thing, if you wanna use the action attribute of the form, you should reference it in the url param of ajax request:

首先,如果你想使用表单的action属性,你应该在ajax请求的url参数中引用它:

url: form.attr('action'),

Now, for the button clicked, you should use this (it's a workaround because submit buttons are not incluided in the form serialization, if not, I would use it instead):

现在,对于单击的按钮,你应该使用它(这是一种解决方法,因为提交按钮不包含在表单序列化中,如果没有,我会改为使用它):

$(function () {

    //When any of the buttons is clicked, we store in the form data the clicked button value
    $('#ajaxform').on('click', 'input[type=submit][name=feeling]', function(e) {

        $(this.form).data('clicked', this.value);
    });

    $('#ajaxform').submit(function (event) {

        event.preventDefault();

        var form = $(this);

        $.ajax({
            url: form.attr('action'),
            type: form.attr("method"),
            data: { clickedButton : form.data('clicked') } //Retrieve the button clicked value from the form data
        });
    });
});

Hi kindly use the following to get the id of the button that has been clicked

嗨请使用以下内容来获取已单击的按钮的ID

$("input").click(function(e){
    var idClicked = e.target.id;
});
