編碼-encodeURI decodeURI

此函數對特殊字符進行編碼。 此外，它還對以下字符進行編碼： , / ? : @ & = + $ #

encodeURI　和　encodeURIComponent

var uri = "my test.asp?name=ståle&car=saab";
var res = encodeURI(uri);
console.log(uri)
console.log(res)


var uri = "https://powenko.com/my test.asp?name=柯博文老師&car=saab";
var res = encodeURIComponent(uri);
console.log(uri)
console.log(res)

encodeURI 和　　decodeURI

var uri = "my test.asp?name=柯博文老師&car=saab";
var enc = encodeURI(uri);
var dec = decodeURI(enc);
var res = enc + "<br>" + dec;

輸出：
Encoded URI: my%20test.asp?name=st%C3%A5le&car=saab
Decoded URI: my test.asp?name=ståle&car=saab

encodeURIComponent 和　decodeURIComponent

var uri = "https://powenko.com/my test.asp?name=柯博文老師&car=saab";
  var uri_enc = encodeURIComponent(uri);
  var uri_dec = decodeURIComponent(uri_enc);
  var res = "Encoded URI: " + uri_enc + "<br>" + "Decoded URI: " + uri_dec;
  document.getElementById("demo").innerHTML = res;

輸出：

Encoded URI: httpsss%3A%2F%2Fpowenko.com%2Fmy%20test.asp%3Fname%3D%E6%9F%AF%E5%8D%9A%E6%96%87%E8%80%81%E5%B8%AB%26car%3Dsaab

Decoded URI: https://powenko.com/my test.asp?name=柯博文老師&car=saab
