如果我对名称中方括号的输入使用jQuery serialize()，为什么会出现这个分号?

I have the following HTML:

我有以下HTML:

<input type="checkbox" id="options_1" value="options_1" name="options[]">  
<input type="checkbox" id="options_2" value="options_2" name="options[]">  
<input type="checkbox" id="options_3" value="options_3" name="options[]">

I check the first two options and send it to the server via ajax in jQuery:

我检查了前两个选项，并通过jQuery ajax发送到服务器:

$.ajax({
    type: "POST",
    url: "myfile.php",
    data: {
        'options':$('input[name="options[]"]').serialize()
    },
    dataType: 'json',
    beforeSend: function(){
           //do some stuff
    },
    success: function(msg){
        //do some stuff
    }
});

Firebug shows me the data that has been posted:

Firebug向我显示已发布的数据:

options options%5B%5D=options_1&options%5B%5D=options_2
So far, so good.

In myfile.php I get the POST-Variable like this:

选项选项%5B%5D=options_1&选项%5B%5D=options_2，到目前为止，很好。在myfile。php后变量如下:

$options = $_POST['options'];

Now when I echo $options I get this:

当我回复$options时，我得到了这个:

"options[]=options_1&options;[]=options_2"

Where does this semicolon in front of the second pair of brackets come from? This is driving me crazy.

在第二对括号前面的分号来自哪里?这让我发疯。

I already used utf8_decode on the POST data as well as urldecode and rawurldecode. Nothing changes. I also escaped the square brackets in the ajax call like this:

我已经在POST数据上使用了utf8_decode以及urldecode和rawurldecode。没有什么变化。我还将ajax调用中的方括号转义为:

data: {
    'options':$('input[name="options\\[\\]"]').serialize()
},

That didn't help either. Any ideas anyone?

这没有任何帮助。有什么想法吗?

I had this exact problem, and I was only able to get it to work by using ".serializeArray()", I hope this was what you were looking for.

我遇到了这个问题，我只能通过使用“.serializeArray()”来使它工作我希望这就是你想要的。

data: {
    'options':$('input[name="options[]"]').serializeArray()
},

For me this outputs standard string in the same format as GET requests.

对于我来说，它以与GET请求相同的格式输出标准字符串。
