如何将逗号分隔的多选值传递给表单提交上的url

时间:2022-04-09 08:39:09

I have a basic GET form in my project that is used to filter through posts created by users. When I submit the form the values from the multiple select input are appended to the url like so:

我的项目中有一个基本的GET表单,用于过滤用户创建的帖子。当我提交表单时,多个选择输入中的值将附加到URL,如下所示:

project.dev/?maps[]=1&maps[]=2&maps[]=3

As you can see, the values are passed to the url via three separate key value pairs... However, I would like to know how to append the values to the url in the following format:

如您所见,值通过三个单独的键值对传递给url ...但是,我想知道如何以下列格式将值附加到url:

project.dev/?maps=1,2,3

Thanks in advance.

提前致谢。

Assuming you're trying to send an array, how about Array.prototype.join?

假设您正在尝试发送数组,那么Array.prototype.join怎么样?

var arr = [1, 2, 3];

console.log(arr.join(','));

// result: 1,2,3
