jQuery ajax:添加表单值 [英] jquery ajax : add form value

问题描述

我正在使用jquery Ajax发布表单值.有没有一种方法可以动态添加值?该代码不起作用:

I am using jquery Ajax to post form values. Is there a way to add values dynamically ? This code doesn't work:

MY_APP_LOGIN.loginFormAttachEvent = function () {
$( "#login" ).unbind('submit').removeAttr('onsubmit').on('submit', function(event) {

        var values = $( this ).serializeArray();
        var o = { foo: 'bar' };
        //o.pageKey = MY_APP_NAV.CMS_PAGE_KEY;
        values.push(o);

        $.ajax({
            type : 'POST',
            url : '/user/loginajax',
            data : values,
            dataType : "json",
        });
    }
    return false;
});

推荐答案

我很久以前就这样做了，我很快从一个旧文件中挖了这个.抱歉，我现在无法为您测试这应该工作:

I had to do this long ago, I quickly dug this up from an old file I did it in. Sorry I can't test it for you now but this should work:

var form = $(this);
var form_data = new FormData(form[0]);
form_data.append('foo', 'bar');
form_data.serializeArray();

我认为您可以跳过序列化，可以直接发送form_data，我认为应该没问题.

I think you can skip the serialize, you can send form_data directly and it should be fine I think.
