urlencode() from PHP in JavaScript?
提问by daGrevis
I'm looking for similar function as urlencode()from PHP just in JavaScript. jQuery library is allowed.
我正在寻找与urlencode()PHP类似的功能，只是在 JavaScript 中。允许使用 jQuery 库。
Basically, I need to encode the string and then redirect the user to another page just with JavaScript.
基本上，我需要对字符串进行编码，然后仅使用 JavaScript 将用户重定向到另一个页面。

There is no function quite matching urlencode(), but there is one quite equivalent to rawurlencode(): encodeURIComponent().
没有完全匹配的函数urlencode()，但有一个完全等同于rawurlencode(): 的函数encodeURIComponent()。
Usage: var encoded = encodeURIComponent(str);
用法： var encoded = encodeURIComponent(str);

Have a look at phpjs.org if you're searching for a JS function equivalent to PHP:
如果您正在搜索与 PHP 等效的 JS 函数，请查看 phpjs.org：
http://phpjs.org/functions/urlencode:573
http://phpjs.org/functions/urlencode:573
Here you can use encodeURIComponent()(with some modifications).
在这里你可以使用encodeURIComponent()（有一些修改）。

My code is the JS function equivalent to PHP's urlencode (based on PHP's source code).
我的代码是相当于PHP的urlencode的JS函数（基于PHP的源代码）。
function urlencode(str) {
let newStr = '';
const len = str.length;
for (let i = 0; i < len; i++) {
let c = str.charAt(i);
let code = str.charCodeAt(i);
// Spaces
if (c === ' ') {
newStr += '+';
}
// Non-alphanumeric characters except "-", "_", and "."
else if ((code < 48 && code !== 45 && code !== 46) ||
(code < 65 && code > 57) ||
(code > 90 && code < 97 && code !== 95) ||
(code > 122)) {
newStr += '%' + code.toString(16);
}
// Alphanumeric characters
else {
newStr += c;
}
}
return newStr;
}

Try urlencode from http://locutus.io/php/url/urlencode/. I've tested it in several cases I had and it worked.

来自：https: //www.php.net/manual/en/function.urlencode.php
Returns a string in which all non-alphanumeric characters except -_. have been replaced with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the ? RFC 3986 encoding (see rawurlencode()) in that for historical reasons, spaces are encoded as plus (+) signs
返回一个字符串，其中除 -_ 之外的所有非字母数字字符。已替换为百分号 (%) 后跟两个十六进制数字和编码为加号 (+) 符号的空格。它的编码方式与来自 WWW 表单的发布数据的编码方式相同，即与 application/x-www-form-urlencoded 媒体类型中的方式相同。这与 ? RFC 3986 编码（参见 rawurlencode()），因为历史原因，空格被编码为加号 (+)
From: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent:
来自：https: //developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent：
encodeURIComponent() escapes all characters except:
Not Escaped: A-Z a-z 0-9 - _ . ! ~ * ' ( )
encodeURIComponent() 转义所有字符，除了：
Not Escaped: AZ az 0-9 - _ 。！~ * ' ( )
A snippet is provided near the bottom of that page which looks like this:
该页面底部附近提供了一个片段，如下所示：
function fixedEncodeURIComponent(str) { return encodeURIComponent(str).replace(/[!'()*]/g, function(c) { return '%' + c.charCodeAt(0).toString(16); }); }
function fixedEncodeURIComponent(str) { return encodeURIComponent(str).replace(/[!'()*]/g, function(c) { return '%' + c.charCodeAt(0).toString(16); }); }
I am slightly adjusting the provided javascript snippet to include a couple more characters.
我稍微调整了提供的 javascript 片段以包含更多字符。
My Code:
我的代码：
function urlEncodeLikePHP(str) {
return encodeURIComponent(str).replace(/[.!~*'()]/g, function(c) {
return '%' + c.charCodeAt(0).toString(16);
});
}
Usage:
用法：
urlEncodeLikePHP("._!_~_*_'_(_)-\-&-|-/");
// effectively: "._!_~_*_'_(_)-\-&-|-/"
Encoded Output:
编码输出：
%2e_%21_%7e_%2a_%27_%28_%29-%5C-%26-%7C
