yes its the same function... I've modified the code because you can't decrypt when the code has been converted to hex. Usage is included in the file: enc.txt;
//encrypt using single DES (with an 8 byte key) in CBC mode with the given input vector
string.DES ("8bytekey", 1, 1, "inputvec");
//encrypt using triple DES (with a 24 byte key) in ECB mode
string.DES ("this is a 24 byte key !!", 1);
//decrypt using single DES in ECB mode
string.DES ("8bytekey", 0);
alert("Hello my name is $name and my favourite colour is $colour[$number] . I bought a bicycle today, it cost $_250 ".interpolate());
instead of alert("Hello my name is " + name + " and my favourite colour is " + colour[number] + ". I bought a bicycle today, it cost $250");
Variables must start with a "$" and finish with a " " (space). To add a dollar sign to the string use $_ (Warning: the $_ is treated as a variable and must end with a space " ").
The code is a bit sloppy as it's all off of the top of my head. It may be a bit buggy as I haven't tested it fully. Anyone is free to rewrite it and make improvements.

var name = new Array();
name[0] = "Ben";
name[1] = "Carl";
name[2] = "Brady";
name['one'] = "John";
var number = 2;
alert("display an array element by its number: {name[0]}, display an array element by a string: {number['one']}, display a variable {number}, don't worry about using {brackets} because if it isn't a variable it isn't processed".S())
alert("Use windows variables in a string: {screen.height}")
</script>
A much more useful version of the interpolation prototype. This is quite useful... don't you agree?
Looks like it could be quite useful to somebody who has become accustom to that method of coding, though for me regular variable concatenation is second nature so I probably won't find much use.
Instead of using:
eval("window." + mySub)
you should use:
window[mySub]
It will prove much more efficient. I am yet to see a case where eval() is actually better than the alternative.
Date.prototype.setMe is a function that accepts 3 arguments and sets the Date Object directly (i.e. it sets it like setTime() w/o returning the date object but actually setting it directly) it accepts the day,Month,Year and sets the Date Object for you in 1-2-3.
Date.prototype.UTCsetMe Let's you set it's Day,Month, and Year for UTC and it uses a zero for it's hours,minutes,seconds,milliseconds.
GMT(Greenwich Mean Time) and UTC(Universal Time Coordinated) are usually thought of as interchangable. The difference is that UTC is atomic time while GMT is an actual timezone.
Array.prototype.getAddedKeys is a function that loops though all of the elements of an array, regardless their keys, and generates a new array with all of the elements side-by-side along with their keys. It's quite hard to explain yet a very powerful function.
Code:
<script type="text/JavaScript"><!--
Array.prototype.getAddedKeys=function(){var a=this,kArray=[],vArray=[],i,l,nArray=[];for(i in a){if(i in Array.prototype)continue;kArray[kArray.length]=i;vArray[vArray.length]=a[i]}l=kArray.length;for(i=0;i<l;i++){nArray[nArray.length]=kArray[i];nArray[nArray.length]=vArray[i];}return nArray}
var b=["zero","one","two","three"];
b[5]="five"
b["number9"]=9
alert(b.getAddedKeys())
//--></script>
Array.prototype.keyAndValueSort is a function built for sorting keys and values. Every other array element is a key followed by the next array element -- it's value. The syntax is as follows:
Code:
[key,value,key,value,key,value]
The function first makes sure that there are an even amount of array elements, otherwise the function is smart-enough to assign a blank string to the last key.
The function preforms the regular sort method on the array's keys and rememeber's the value for each key which is what makes this function useful in the first place.
This function is also smart enough to know that there can only be one unique key of any given name. If you have more than on key with the same name, the function will ignore the key and value of the first and use the key and value of the last instead.
When the function is finished, it returns an array in the same syntax as goes into the function:
Code:
[key,value,key,value,key,value]
Happy coding!
Code:
<script type="text/javascript">
Array.prototype.keyAndValueSort=function(){
var l=this.length;
var bl=l;if(bl%2==1)bl--;
var keys=new Array();
var values=new Array();
for(var i=0;i<l;i+=2){
keys[keys.length]=this[i]
if(i==bl){values[values.length]="";break}
values[values.length]=this[i+1]
}
l=keys.length
var nObj={};
for(i=0;i<l;i++){
nObj[keys[i]]=values[i];
}
var nKeys=new Array();
for(i in nObj){
nKeys[nKeys.length]=i
}
nKeys.sort();
l=nKeys.length;
var nValues=new Array();
for(i=0;i<l;i++){
nValues[nValues.length]=nObj[nKeys[i]]
}
var outArray=new Array();
for(i=0;i<l;i++){
outArray[outArray.length]=nKeys[i]
outArray[outArray.length]=nValues[i]
}
return outArray;
}
</script>
<script type="text/javascript">
//simple key and value sorting example:
var a=["a",1,"b",2,"d",4,"c",3];
alert(a.keyAndValueSort())
//the key "key1" appears twice in the array and the function will ignore the first key and value
var j=["key1","overridedvalue","key2","there","key1","hi","key3","!"];
alert(j.keyAndValueSort())
</script>
I have used the built-in indexOf method much too long and saw reason to build a better method. There should be a way for indexOf to return an array containing ALL the indexOf-instaces of the search string rather than just the index of the first instance. Regular Expressions come with a "g" modifier flag, why can't indexOf also come with one?
String.prototype.indexesOf will go through the entire string collecting all instances into an array. If no matches are found, it returns a blank array (not a -1). For each match it finds, it's indexOf is added to the array.
(function(){
var a = window.alert;
window.alert=function(q){
a("BigMoosie\n\n"+q);
}
})();
This code will add the word 'BigMoosie' to every single alert called. This is quite neat as the workaround has been enclosed within an empty function making the variable 'a' inaccessible to global functions.
I wish to do a similar thing to a prototype function for example this will make the split function's first argument defualt to an empty string if it is not set:
However this is not as neat because the split2 function is global and can be accessed by other codes still, how would I make it private like in the previous example?
I have a great idea for a RegExp prototype function: (unfinished)
Code:
<script type="text/javascript">
RegExp.prototype.getRandomMatch=function(){
var rearray=this.toString().split('/');
var re=rearray[1];var flags=rearray[2]
alert("RegExp:\n"+re+"\n\nFlags:\n"+flags);
}
var reg=/\d\w[a-zA-Z]/ig;
reg.getRandomMatch()
</script>
Just imagine creating a really complex RegExp that you barely even finish writting,
Here's a nice randomly useless one, semi-inspired by Cinders.
Code:
String.prototype.makeStupid = function(stupidityLimit){
var stupid = new Array();
var stupidness = "";
/*
Add in your stupidisms here, the later they are declared, the less likely they
are to occur.
*/
stupid[stupid.length] = "!";
stupid[stupid.length] = "1";
stupid[stupid.length] = "eleven";
stupid[stupid.length] = "twelve";
stupid[stupid.length] = "SHIFT+1";
/*
The higher the value of the "stupidityRareness" variable, the less often the
later values in the array occur.
*/
var stupidityRareness = 20;
for( var n=0; n < stupidityLimit; n++){
stupidness += stupid[Math.floor(stupid.length * Math.pow(Math.random(),stupidityRareness))];
}
return this+stupidness;
}
alert("PWNZ0R8T3D!".makeStupid(50));
