使标签像输入按钮一样

Question

我怎样才能<a href="http://test/com/tag/test">Test</a>像表单按钮那样表现？通过表现形式按钮,我的意思是当点击链接做一个method="get"或发布,以便能够通过获取或发布捕获它.

没有必要成为一个链接,我可以适应,以使其像这样工作!

如果您想使用链接提交表单:

HTML -

<form action="my-page.php" id="my-form" method="post">...</form>
<a href="#" id="form-submit">SUBMIT</a>

JS -

$(function () {
    $('#form-submit').on('click', function () {

        //fire the submit event on the form
        $('#my-form').trigger('submit');

        //stop the default behavior of the link
        return false;
    });
});

如果您想在不离开页面的情况下提交表单,可以使用AJAX调用:

$(function () {
    $('#form-submit').on('click', function () {

        //cache the form element for use later
        var $form = $('#my-form');
        $.ajax({
            url     : $form.attr('action') || '',//set the action of the AJAX request
            type    : $form.attr('method') || 'get',//set the method of the AJAX reqeuest
            data    : $form.serialize(),
            success : function (serverResponse) {

                //you can do what you want now, the form has been submitted, and you have received the serverResponse
                alert('Form Submitted!');
            }
        });
    });

    $('#my-form').on('submit', function () {

        //stop the normal submission of the form, for instance if someone presses the enter key inside a text input
        return false;
    });
});

请注意,这.on()是jQuery 1.7中的新增内容,在这种情况下与使用相同.bind().
