点击链接后,JQuery提交表单

标签: php javascript jquery ajax

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?

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。

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;
});

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。
