Here are 2 prototype-functions I created.

There are alot of useful prototype functions through-out this thread. It's well-worth the time to browse through them.
Feel free to add your own prototype functions to this thread.
However, make sure that you've tested your functions before you post them.
Also, do not post anything but prototype functions in this thread.
Post your non-prototype-functions here: Function Library

This code defines the functions replaceAt and multipulCopies

<SCRIPT TYPE="text/javascript">
String.prototype.replaceAt=function(){return this.substring(0,arguments[0])+arguments[1]+this.substring(arguments[0]+1,this.length)}
String.prototype.multipulCopies=function(){var temp="";for(var i=0;i<arguments[0];i++){temp+=this}return temp}
</SCRIPT>

Ultimater

Doesn't anybody like my functions!?

BigMoosie

I cant see many uses for them, and anyway, if I did one day need one I wouldnt think back to this thread I would immediately write the same solution that you have come up with, cos theyre only a couple of lines each

Ultimater

How dare you insult the functions of Ultimater! :eek:

I wouldn't belittle them so much. They are highly reuseable functions that are well-tested.
If you have a JS-header file that you include in all of your programs, you should also include these
I still acknowledge them just as much.

robo_neojetsam

That is a nice little bit of code that really could save people time, thanks for that.

You should submit it to the JavaScript Source ( http://javascript.internet.com )

Ultimater

Last time I submitted some code to them, and the only time -- being about 2 months ago,
they never publicized it yet... There was nothing wrong with or repulsive regarding the code either.
I was thinking about making a forums in my website special for tips & tricks and another for functions.
I also considered seperating each forum into two pieces -- one where I post and one where other people post.
That should make it easy for me to add tips & tricks ,etcetera to my forums.

PS: Thanks for acknowledging my functions.

BigMoosie

I think the reason JavaScript source did not accept your codes was because they are after cut and paste scripts that people who have no understanding of JavaScript can use. That is not the website for coding tools.

Ultimater

It's possible... Either way, I'm not going to submit any more code to them.
If anyone else feels they have the time to fill-out all of their forms, go ahead and submit it.

HaganeNoKokoro

I've always thought Javascript Source was pretty useless. I've tried submitting things to them in the past, and watched as my scripts were never posted while genuine crap was.

Example of the crap they let through: http://javascript.internet.com/calculators/number-of-primes.html

Dude, that's just pathetic.

herodote92

I think it would be interesting to have a full library of such string prototype functions at hand. Most of them are rather simple to write, but it's such boring to have to rewrite them every time you need them. Well, I guess such libraries exist alreay, one just has to find them (and it will likely be faster to rewrite the exact one you need than to find it).

Now the next step will be: writing the String.prototype.translateToFrench() function :-)

Ultimater

rotl... I'm glad that I'm not the only one being turnned down!
That makes me feel somewhat better.
That's just hilarious!

Ultimater

Well I don't know any french so I won't be the one creating that function...
I am, however, working on creating a big numbers function.
i.e. it will add or subtract two hugh numbers, both from any base, and return the result in the same base w/o using scientific notation.
It's not that hard... Mostly when creating such functions, I just simply need my coffee.

BigMoosie

I have had 12 accepted at that site, its bloody easy, I think I only make 3 or 4 that didnt get on. Being featured on JavaScript source and having links in random places around the internet from people who have copied them has given my old site a google ranking of 5.

Beware! I made these years ago when I was quite crap at javaScript so they only work in IE! and the ones at the bottom are pretty crap...

My scripts:

Ultimater

Hey, if anyone has any prototype-functions that they wish to share with the public,
this is the place.

robo_neojetsam

oh yeah, i have a few protoype scripts, im not the best at javascript, i think im better at CSS. One of my prototypes includes a navigation bar that is static at the top of the page, it allows access to mail box and stuff like that, its half finished though.

BigMoosie

hmmm... robo_neojetsam probably misunderstands the meaning of prototype...

robo_neojetsam

i guess it really isnt a prototype, but who cares.

Heres a little something that i just wrote up, its very simple, when an Javascript error is found, it alerts the user and asks to block it.

Heres the code itself (without any errors):

<script>
function checkerror(){
alert('A Javascript Error has been found.');
var answer=confirm("Do you wish to block this error?")
if (answer) {
return true;
alert('The Javascript Error has blocked.');
}
else {
alert('The Javascript Error on this page has not been blocked.');
}
}
window.onerror = checkerror;
</script>

And heres the error part (which i am sure most of you can make REAL quick )

<script>
ERROR
function makeerror() {
dfsfsdfsdfsdf
}
</script>


<a onclick="javascript:makeerror()" href="http://www.google.com">Make error and redirect</a>

i think its cool...

BigMoosie

One problem with that, this part should be:

if (answer) {
alert('The Javascript Error has blocked.');
return true;
}

if you want to actually get the alert,

If i were to use a code like this i would rather:

<script>window.onerror=Function("return true")</script>

because the only person who actually cares where the error occurs is the person debugging it. The user is likely to not care about the details of the error and if it is possible to pass it off pretending no error occured then that is the best.

robo_neojetsam

i think the user should interact with the website as much as possible, to keep them entertained, this code could be usefull if the site has a special 'place' where the member can upload HTML and Javascript to make their own page about them etc. Another use for this code could be a HTML/Javascript test area. i think the code is ok, after all im a 13 year old Javascript beginer.
