点击链接后，JQuery提交表单

Question

这是JQuery：

$(document).ready(function() {
    $('#autosave').click(function() {
        var url = window.location.pathname;
        $postData = $('#content form:first').serialize() + '&'
                    + $('#content form:first .input-submit').attr('name')
                    + '=Save';
        $.post(url, $postData, function(data) {
            //
        });
    });
});

它应该做什么：

单击#autosave链接后，页面上#content div中的第一个表单将使用POST方法提交。之后，用户将被带到链接目标。

此：

$postData = $('#content form:first').serialize() + '&'
            + $('#content form:first .input-submit').attr('name')
            + '=Save';

从表单中收集数据，并将提交按钮添加到最后（因为在PHP代码中，我正在检查是否先提交了提交按钮，然后进行表单验证和处理）。

此：

var url = window.location.pathname;

是提交表单的URL（与表单所在的页面相同）。

问题当然是它不起作用。

点击链接后，我被带到链接目标，但表单尚未提交（因为数据库中没有任何更改）。

有什么想法吗？

Answer 1

尝试：

$(document).ready(function() {
    $('#autosave').click(function() {
        var url = window.location.pathname;
        $postData = $('#content form:first').serialize() + '&'
                    + $('#content form:first .input-submit').attr('name')
                    + '=Save';
        $.post(url, $postData, function(data) {
            window.location.href = url;
        });

        return false;
    });
});

编辑：我的不好，window.location.href = url;应该是window.location.href = $(this).attr('href');，正如tvanfosson在他的回答中所做的那样。

EDIT2 ：

这适用于我（使用PHP后端脚本测试），使用您的HTML代码（包装成<div id="content">YOUR HTML</div>）：

$('#autosave').click(function() {
    var url = window.location.pathname;

    $postData = $('#content form:first').serialize() + '&'
                + $('#content form:first .input-submit').attr('name')
                + '=Save';

    $.post(url, $postData, function(data) {
        window.location.href = $('#autosave').attr('href');
    });

    return false;
});

Answer 2

您需要在帖子实际返回后导航到链接目标。这样，当遵循链接href时，将不会卸载（并且不提交）挂起的帖子请求。

$(document).ready(function() {
    $('#autosave').click(function() {
        var url = $(this).closest('form').attr('action');
        $postData = $('#content form:first').serialize() + '&'
                    + $('#content form:first .input-submit').attr('name')
                    + '=Save';
        $.post(url, $postData, function(data) {
            // take link after post
            window.location.href = $(this).attr('href');
        });
        return false;  // stops initial link action
    });
});

如果不应该使用链接，请更改回调函数以使用数据 在服务器端验证失败的情况下。使用if语句对返回的数据进行简单检查就足够了。
