jQuery $.post 不传递按下的按钮

最近我遇到了一个问题,即 $.post 不发送有关按下的按钮的信息。 即我们有一个带有两个按钮的表单。

<form method="post"  action="/home/index">

  <input type='hidden' name='data1' value='value1' />

  <button name="button1" type="submit">First</button>
  <button name="button2" type="submit">Second</button>

</form>

$(document).ready(function() {
    $('#formId').submit(function () {
        var f = $(this);
        var action = f.attr("action");
        var serf = f.serialize();
        $.post(action, serf,
        //onreturn
          function (data) {
                //do something here on success
              },
              'json'
          );
        return false;
      });
});

如果用户按下第一个按钮,没有 ajax 的表单将按如下方式发布:data1=value1&button1

但是当我使用 $.post 发布的表单时,不包含有关按钮的任何信息:data1=value1 strong>

jQuery 1.6.1

行为取决于按下的按钮。 任何帮助或解决方法将不胜感激!

Recently I've stuck with a problem where $.post does not send information about button which were pressed.
I.e. we have a form with two buttons.

<form method="post"  action="/home/index">

  <input type='hidden' name='data1' value='value1' />

  <button name="button1" type="submit">First</button>
  <button name="button2" type="submit">Second</button>

</form>

$(document).ready(function() {
    $('#formId').submit(function () {
        var f = $(this);
        var action = f.attr("action");
        var serf = f.serialize();
        $.post(action, serf,
        //onreturn
          function (data) {
                //do something here on success
              },
              'json'
          );
        return false;
      });
});

Without ajax form is posted as following if user pressed First button: data1=value1&button1

But when I use $.post posted form does not contain any information about button: data1=value1

jQuery 1.6.1

The behavior depends on that which button were pressed.
Any help or workaround would be appriciate!

由于您要停止浏览器的默认行为(即提供按钮值的行为),因此您必须捕获按下的按钮,并将该信息添加到您发布的数据中(您的 serf数据)。也许最可靠的方法是挂钩按钮上的 click 事件以及表单的 submit 事件,并将它们全部路由到执行以下操作的中央函数:使用(或不使用)按钮值的 ajax 提交(在以另一种方式提交表单的情况下,不使用按钮值,而不是按其中一个按钮)。

沿着这些思路:

$(document).ready(function() {
    function submitTheForm(f, button) {
        var action = f.attr("action");
        var serf = f.serialize();
        if (button && button.name) {
            serf += "&" + encodeURIComponent(button.name);
            if (button.value) {
                serf += "=" + encodeURIComponent(button.value);
            }
        }
        $.post(action, serf,
        //onreturn
          function (data) {
                //do something here on success
          },
          'json'
        );
    }
    $('#formId').submit(function () {
        submitTheForm($(this));
        return false;
    });
    $("#formId :submit").click(function() {
        submitTheForm($(this).closest('form'), this);
        return false;
    });
});

Since you're stopping the browser's default behavior, which is what supplies the button value, you'll have to capture what button was pressed, and add that information to the data you're posting (your serf data). Probably the most reliable way would be to hook the click event on the buttons as well as the submit event of the form, and route them all to a central function that does the ajax submission with (or without) a button value (without in the case of a form submitted another way, rather than by pressing one of those buttons).

Something along these lines:

$(document).ready(function() {
    function submitTheForm(f, button) {
        var action = f.attr("action");
        var serf = f.serialize();
        if (button && button.name) {
            serf += "&" + encodeURIComponent(button.name);
            if (button.value) {
                serf += "=" + encodeURIComponent(button.value);
            }
        }
        $.post(action, serf,
        //onreturn
          function (data) {
                //do something here on success
          },
          'json'
        );
    }
    $('#formId').submit(function () {
        submitTheForm($(this));
        return false;
    });
    $("#formId :submit").click(function() {
        submitTheForm($(this).closest('form'), this);
        return false;
    });
});

我认为这不会发生。但无论如何,你也可以做这样的事情。

$("#formid").children("input[type="submit"]").click(function() {
    var name = $(this).attr("name");
    post(name);
    return false;
});
function post(buttnname) {
    var action = $("#formid").attr("action");
    var serf = $("#formid").serialize()+"&button="+buttname;
    $.post(action, serf,
    //onreturn
        function (data) {
            //do something here on success
          },
          'json'
        );
}

I don't think that is suppose to be happening. But anyways, you could something like this too.

$("#formid").children("input[type="submit"]").click(function() {
    var name = $(this).attr("name");
    post(name);
    return false;
});
function post(buttnname) {
    var action = $("#formid").attr("action");
    var serf = $("#formid").serialize()+"&button="+buttname;
    $.post(action, serf,
    //onreturn
        function (data) {
            //do something here on success
          },
          'json'
        );
}
