The following are examples of using custom javascript sections, use the "Test" button to apply to the main textarea above.

1. Encoder that obfusticates "%" with \x format:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; // Modify Data and write back into window obj.value = Data.replace(/\%/gi, "\\x");
   
   
2. Decoder that de-obfusticates \x into "%" format:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; // Modify Data and write back into window obj.value = Data.replace(/\\x/gi, "\%");
   
   
3. Encoder that uses encodeURI() instead of escape:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; // Modify Data and write back into window obj.value = encodeURI(Data);
   
   
4. What the "Encode" button above uses:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; // Modify Data and write back into window obj.value = escape(Data);
   
   
5. What the "Decode" button above uses:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; // Modify Data and write back into window obj.value = unescape(Data);
   
   
6. What the "UTF8 Enc" button above uses:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = obj.value; var utf8txt = ""; for(var n=0; n<Data.length; n++) { var c=Data.charCodeAt(n); // all chars from 0-127 => 1byte if (c<128) utf8txt += String.fromCharCode(c); // all chars from 127 to 2047 => 2byte else if((c>127) && (c<2048)) { utf8txt += String.fromCharCode((c>>6)|192); utf8txt += String.fromCharCode((c&63)|128); } // all chars from 2048 to 66536 => 3byte else { utf8txt += String.fromCharCode((c>>12)|224); utf8txt += String.fromCharCode(((c>>6)&63)|128); utf8txt += String.fromCharCode((c&63)|128);} } obj.value = escape(utf8txt);
   
   
7. What the "UTF8 Dec" button above uses:
   // Get location of input window above var obj = document.getElementById('src'); // Get data from input window above var Data = unescape(obj.value); var plaintxt = ""; var i=0; var c=c1=c2=0; while(i<Data.length) { c = Data.charCodeAt(i); // all chars from 0-127 => 1byte if (c<128) { plaintxt += String.fromCharCode(c); i++; } // all chars from 127 to 2047 => 2byte else if((c>191) && (c<224)) { c2 = Data.charCodeAt(i+1); plaintxt += String.fromCharCode(((c&31)<<6) | (c2&63)); i+=2; } // all chars from 2048 to 66536 => 3byte else { c2 = Data.charCodeAt(i+1); c3 = Data.charCodeAt(i+2); plaintxt += String.fromCharCode(((c&15)<<12) | ((c2&63)<<6) | (c3&63)); i+=3; } } // Write data back into input window above obj.value = plaintxt;
   
   
8. using functions:
   // Get location of window above var obj = document.getElementById('src'); // Get Data in windows above var Data = obj.value; // Wrap functions into a variable (C++ style) var func_MyFunctionWrapper = { // the reverse() function reverses the order of characters in the string passed to it // the randomise() function generates a random string of same length as input, or 200 chars if input=0 // public method reverse : function (input) { // local variable var Data=''; if (input.length<1) input='This gets reversed'; // Reverse string for (var a=input.length;a>-1;a--) { Data+=input.charAt(a); } return Data; }, // Public method randomise : function (input) { // local variable var string=''; var len=(input.length>0 ? input.length : 200); for (a=0;a<len;a++) { string += String.fromCharCode(Math.floor(Math.random(0)*93)+33); } // Return modified string return string; } } Data=func_MyFunctionWrapper.reverse(Data); // Modify Data and write back into window obj.value = Data; alert("function reverse()"); Data=func_MyFunctionWrapper.randomise(Data); // Modify Data and write back into window obj.value = Data; alert("function randomise()");
