urlSearchParams.forEach(fn[, thisArg])

版本历史

版本	变更
v18.0.0	将无效回调传给 `fn` 参数现在会抛出 `ERR_INVALID_ARG_TYPE` 而不是 `ERR_INVALID_CALLBACK`。

fn <Function> 为查询中的每个名称-值对调用
thisArg <Object> 在调用 fn 时用作 this 值

迭代查询中的每个名称-值对并调用给定的函数。

const myURL = new URL('https://example.org/?a=b&c=d');
myURL.searchParams.forEach((value, name, searchParams) => {
  console.log(name, value, myURL.searchParams === searchParams);
});
// 打印:
//   a b true
//   c d true

Version	Changes
v18.0.0	Passing an invalid callback to the `fn` argument now throws `ERR_INVALID_ARG_TYPE` instead of `ERR_INVALID_CALLBACK`.

fn <Function> Invoked for each name-value pair in the query
thisArg <Object> To be used as this value for when fn is called

Iterates over each name-value pair in the query and invokes the given function.

const myURL = new URL('https://example.org/?a=b&c=d');
myURL.searchParams.forEach((value, name, searchParams) => {
  console.log(name, value, myURL.searchParams === searchParams);
});
// Prints:
//   a b true
//   c d true
