FLASH 8 使用 URL encode

在網頁傳值的時候常常會用到 URL encode

但FLASH 8本身 沒有提供URLencode的方法(不過CS3有)

decodeURI()
decodeURIComponent()
encodeURIComponent()

這幾種方式可以用，不過只有CS3 才有

所以弄了一個擴充 String 的方法

String.prototype.encodeURIComponent = function() {
 var Result = [];
 var len = this.length;
 for (var i = 0; i   Result.push(this.charAt(i).toUtf8());
 }
 return Result.join("");
};
String.prototype.toUtf8 = function() {
 var code = this.charCodeAt(0);
 if (code   return "%0" + code.toString(16);
 }
 var iByte = 0;
 var i = 0;
 var Result = "";
 while (code > 0x7f) {
  iByte = code % 0x40;
  code = (code - iByte) / 0x40;
  Result = "%" + (iByte | 0x80).toString(16).toUpperCase() + Result;
  i++;
 }
 prefix = [0x0, 0xc0, 0xe0, 0xf0, 0xf8, 0xfc];
 if (i > prefix.length) {
  i = 5;
 }
 Result = "%" + (code | prefix[i]).toString(16).toUpperCase() + Result;
 return Result;
};
String.prototype.encodeURI = function() {
 var result = [];
 var len = this.length;
 for (var i = 0; i   var code = this.charCodeAt(i);
  if (code    //if (code == 61 || code == 38) {
   result.push(this.charAt(i));
  } else {
   result.push(this.charAt(i).toUtf8());
  }
 }
 return result.join("");
};
var st = "http://220.133.52.91/羊小咩?a=10&b=lamb-mei";
trace(st.encodeURI());
trace(st.encodeURIComponent());
String.prototype.encodeURIComponent = function() {
 var Result = [];
 var len = this.length;
 for (var i = 0; i 
  Result.push(this.charAt(i).toUtf8());

 }
 return Result.join("");
};
String.prototype.toUtf8 = function() {
 var code = this.charCodeAt(0);
 if (code   return "%0" + code.toString(16);
 }
 var iByte = 0;
 var i = 0;
 var Result = "";
 while (code > 0x7f) {
  iByte = code % 0x40;
  code = (code - iByte) / 0x40;
  Result = "%" + (iByte | 0x80).toString(16).toUpperCase() + Result;
  i++;
 }
 prefix = [0x0, 0xc0, 0xe0, 0xf0, 0xf8, 0xfc];
 if (i > prefix.length) {
  i = 5;
 }
 Result = "%" + (code | prefix[i]).toString(16).toUpperCase() + Result;
 return Result;
};
String.prototype.encodeURI = function() {
 var result = [];
 var len = this.length;
 for (var i = 0; i   var code = this.charCodeAt(i);
  if (code    //if (code == 61 || code == 38) {
   result.push(this.charAt(i));
  } else {
   result.push(this.charAt(i).toUtf8());
  }
 }
 return result.join("");
};
var st = "http://220.133.52.91/羊小咩?a=10&b=lamb-mei";
trace(st.encodeURI());
trace(st.encodeURIComponent());

output

http://220.133.52.91/%E7%BE%8A%E5%B0%8F%E5%92%A9?a=10&b=lamb-mei
%68%74%74%70%3A%2F%2F%32%32%30%2E%31%33%33..(太長了)

有兩種方式

String.encodeURI ()

String..encodeURIComponent();
一種只會將特殊字.. Unicode 轉換成UTF-8

另外一種是全部都轉換…

P.S 新的值都是直接retrun 所以用的時候要

var str = “http://220.133.52.91/羊小咩?a=10&b=lamb-mei”;
var newstr = str.encodeURI();
