Jquery ajax返回404未找到

I'm using Ajax to pass my form data and files to a PHP file for processing.

我使用Ajax将表单数据和文件传递给PHP文件进行处理。

Javascript:

Javascript:

$("form#applyform").submit(function(){

var data = new FormData();
jQuery.each($('#file')[0].files, function(i, file) {
    data.append('file-'+i, file);
});

$.ajax({
    url: 'ValidateApplication.php',
    data: data,
    cache: false,
    contentType: false,
    processData: false,
    type: 'POST',
    success: function(data){
        alert(data);
    }
});

}

ValidateApplication.php definitely exists. I can view it if I type in the address into the web browser, however when I submit the form chrome console returns 404.

ValidateApplication。php肯定存在。如果我在web浏览器中输入地址，我可以查看它，但是当我提交表单时，chrome控制台返回404。

The PHP is in the same folder as the HTML page the JavaScript is running on so I am confused as to why I keep getting a 404.

PHP与JavaScript运行的HTML页面位于同一个文件夹中，因此我很困惑为什么会一直得到404页面。

UPDATE

更新

Changing POST to GET gets rid of the 404 error, but returns a 500 Internal Server Error

更改POST以消除404错误，但返回500个内部服务器错误

UPDATE 2

更新2

Changing the action of the form to ="ValidateApplication.php" and submitting it as normal (without AJAX) leads to the correct file without any errors.

将表单的操作更改为=“ValidateApplication”。php“并按常规(不使用AJAX)提交它会导致正确的文件，不会出现任何错误。

It seemed to be a problem with the FormData object. Once I changed my method to use .serialize() instead, the page worked just fine.

它似乎是FormData对象的问题。一旦我将方法改为使用.serialize()，页面就可以正常工作了。

$("form#applyform").submit(function(){

    var data = $("form#applyform").serialize();
    jQuery.each($('#file')[0].files, function(i, file) {
        data.append('file-'+i, file);
    });

    $.ajax({
        url: 'ValidateApplication.php',
        data: data,
        cache: false,
        contentType: false,
        processData: false,
        type: 'POST',
        success: function(data){
            alert(data);
        }
    });
}

I've had the same issue and after 2 hours looking for what was causing the 404 Not Found error I found that I was recently playing with the header() from PHP and had forgotten to delete the following line of code:

我也遇到过同样的问题，在查找导致404 Not Found error的原因两小时后，我发现我最近在使用PHP中的header()，并忘记删除以下代码行:

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");

After deleting it, my Ajax functions became normal again.

删除之后，我的Ajax功能又恢复了正常。

#3

For me, it was that I used an input field with name="name" which made the called page return a 404. Weird stuff, hope this helps someone.

对我来说，我使用了name="name"的输入字段，这使得被调用的页面返回404。奇怪的东西，希望这能帮助别人。

Try adding a / before the filename: url: '/ValidateApplication.php',

尝试在文件名:url: '/ValidateApplication.php'中添加一个/之前，

Try changing the request type from POST to GET and see if it works.

尝试从POST中更改请求类型，以获取并查看它是否有效。

Try commenting out parts of the code:

尝试注释代码的部分:

/*cache: false,
contentType: false,
processData: false,*/

Try another browser.

尝试另一个浏览器。
