If yes, can someone give me the code? Thank you. smile

JavaScript can do prettymuch whatever u want! its a full fledged programming language that is comparable to C++ tongue

" A basic tutorial to javaScript and webdesign" < That book taught me Html , CSS , JavaScript in 24 hours so is a must read!!!

The way I "print" things in javascript is with text boxes, but

Code:

document.write("I want to print this");

is also a way to do it.

Code:

<HTML>
<HEAD>
<SCRIPT TYPE="text/javascript">
function PrintNumbers()
{
var x = (Math.random()*1000)
document.abc.def.vaue = x;
}
</SCRIPT>
</HEAD>
<BODY onLoad="PrintNumber()">
<form name="abc">
<INPUT type="text" name="def"
</form>
</BODY>
</HTML>

What code does:

onLoad="PrintNumbers()" means that when the page is loaded, activate the function PrintNumbers

function PrintNumbers: first this declares a variable and sets it to a random number. The next line of code prints that in the text box. Replace it with document.write(x); to actually print it.

MoreGamesNow · 2011-05-03 07:17:31

Oh, and as far as reading text, I'm not sure if it can read direct text from a web site, but it can definitely report the value of a text box.

Using the text box above, the value is found simply with this: document.abc.def.value

So to make an alert box with the value of the text box: alert(document.abc.def.value);

To learn more, go to w3schools here, or just keep asking me big_smile

MoreGamesNow · 2011-05-04 07:23:01

Sorry, but I'm still not sure what you want, the link led me to a page that was blank, except for a list of numbers. What do those mean/correspond to?

scimonster · 2011-05-04 07:27:15

Those are the IDs of my most recent projects. I would like to have the page read digits 1-7 together, a different page digits 9-15, and then another page digits 17-23.

MoreGamesNow · 2011-05-04 20:14:29

Well, you could manually put the numbers into a list, but that is probably not what you have in mind. Other than that, I'd copy that and put it in a text box. I'd do this

Code:

<HTML>
<HEAD>
<SCRIPT TYPE="text/javascript">
var list="1747295:1690716:1690245:1677417:1677281:1660215:1659776:1588557:1582546:1574540:1543141:1541120:1540857:1539084:1538158:1532177:1518131:1512356:1505665:1495530:1491433:1487985:1487630:1485149:1477427:1460795:1446725:1440454:1440144:1435153:1435147:1430744:1429930:1424257:1423968:1423866:1423583:1417720:1408540:1404706:1399926:1394611:1394563:1394365:1394361:1381117:1381067:1381050:1378830:1376373:1374432:1372825:1349186:1349039:1348557:1340626:1339277:1339247:1334438:1334308:1322548:1170738:1139325:1132172:1132155:1122458:1108971"
function SortList()
{
var RealList=list.split(":");
var i;

    for(i=0; i<RealList.length; i++)
    {
        var address = "http://scratch.mit.edu/projects/scimonster/"+RealList[i];
        document.write("<a href="+address+">Project "+(i+1)+"</a><BR>");
    }
}
</SCRIPT>
</HEAD>
<BODY onLoad="SortList();">
</BODY>
</HTML>

Is this what you're trying to make (prints out links to all your projects base on the list you gave me, should be adaptable to any additional projects you make.

MoreGamesNow · 2011-05-04 20:16:54

So to answer your question, to read the numbers only, just set a list to the list of numbers with .split(":").

Example: var NewList = OldListofNumbers.split(":");

this will make NewList generate a list (or array) of all the numbers you write (if presented with a colon. If you want to use commas or some other symbol, just replace the colon in the parentheses with that symbol.

scimonster · 2011-05-04 21:04:18

And if I replace the var list="1747295:...." with var list=http://scratch.mit.edu/api/getprojectsbyusername/scimonster
It should work?

scimonster · 2011-05-04 21:39:25

Oh yeah, and how do I read just one item of the list then?

MoreGamesNow · 2011-05-04 21:39:51

If you replace list=1747295:1690... with list=http://scratch.mit.edu/api/getprojectsbyusern ame/scimonster, the computer won't know the last digits of the address, unless you're replacing "list" with items that include the numbers:

list=http://scratch.mit.edu/api/getprojectsbyusername/scimonster/1747295:http://scratch...

If you do that, then you can get rid of the whole "var address" line and replace "+address+" with "+list[i]+", and the result should be the same.

On another note, if I were you I'd do this instead:

Don't use "1747295:169071...", but just put it directly into RealList. It would look like this:

RealList = 1747295,1690716,1690245,1677417,167728...

You use commas instead of colons, and you don't encase the whole thing with quotes (though you could put each item/element in quotes, but it doesn't make any difference since they become strings anyway). Then you can get rid of the list.split method.

scimonster · 2011-05-04 21:42:23

No, the api page is the one that has the numbers I want to read- the whole point is that I don't have to update it manually.

fg123 · 2011-05-04 21:47:47

I see, you want to grab the pages' content dynamically...

http://www.rgagnon.com/jsdetails/js-0035.html

This page seems useful , from google.

scimonster · 2011-05-04 21:54:41

I only want certain characters though. (Sorry for being so difficult.)

wmays · 2011-05-04 21:59:45

I think he's trying to find a way to show his most recent projects on his website and update it dynamicaly.

fg123 · 2011-05-04 22:01:48

Certain characters? Then grab the pages content, and sort it into a list, then, delete the ones you don't need. Then print out the ones you need...

Actually my wiki page. tongue

Here's my current code on the page:

Code:

With 6 JS subpages, it would be like this, without discriptions:

Code:

<big>'''My Latest Projects'''</big></div>
{| border="1" style="width:100%; text-align:center;"

@fg123: But I don't know JS.

I'm still confused. Over all, what are you trying to do?

scimonster · 2011-05-04 22:05:54

Have the JS read the numbers from the api page and print it, but only some numbers.
