syntax question (simple i guess)

i’ve got a -maybe dumb- question since i’ve never had a single js lesson ?

i want to catch some divs in a page, at first i got all the names of them from a db, but now they are dynamicly generated.
so.. i couldnt use php anymore.. so.. this is what i came up with:

[CODE] if (obj.name.match(‘resize’))
{
instance = str.replace(/resize/,””);

elements.q+instance+.resizeTo(dd.obj.x-elements.q+instance+.x+12, ((obj.y+12)-dd.elements.q+instance+.y));
elements.opt+instance+.moveTo(dd.obj.x-24, dd.obj.y);
elements.movemove+instance+.moveTo(dd.obj.x-12, dd.obj.y);
}[/CODE]

well, this doesnt work.
example:
object name is “resize[B]1[/B]“
i strip resize
and i want to get:
elements.movemove[B]1[/B].moveTo(dd.obj.x-12, dd.obj.y);

you know what i mean ?

@jonavanmonaauthorNov 12.2006 — str. is for example resize1.

its a given variable.

so in one way or another i have to get the number ('1' in this case), glued into elements.movemove.moveTo(dd.obj.x-12, dd.obj.y); so it becomes

elements.movemove1.moveTo(dd.obj.x-12, dd.obj.y);

@konithomimoNov 12.2006 — You can use replace like you have it, or you can use split. for example, here it is with replace:
<script type="text/javascript">
function changeName(){
var divs = document.getElementsByTagName('div');
var changeFrom = 'resize';
var changeTo = '';
var hold, instance;
for(var i=0;i<divs.length;i++)
{
if(divs[i].name.match(changeFrom))
{
instance=changeFrom.replace(changeFrom,changeTo);

hold = "elements.q"+instance+".resizeTo(dd.obj.x-elements.q"+instance+".x+12, ((obj.y+12)-dd.elements.q"+instance+".y));
elements.opt"+instance+".moveTo(dd.obj.x-24, dd.obj.y);
elements.movemove"+instance+".moveTo(dd.obj.x-12, dd.obj.y)";
}
//now do whatever you want to do with the variable hold...
return;
}
</script>

@jonavanmonaauthorNov 12.2006 — thanks for your help!

you know the thing is, i dont need it as a variable(string).

i mean, in the function -elements.movemove1.moveTo(dd.obj.x-12, dd.obj.y);- moves an object (a div) and if its in a variable, it won't move anything.

right? ?

@jonavanmonaauthorNov 12.2006 — and when i do

elements.movemove+number+.moveTo(dd.obj.x-12, dd.obj.y);

i get a syntax error

@konithomimoNov 12.2006 — that is because using the addition signs makes it a string. That is why i left it as a variable. Once you have the variable you can eval(), thus treating it as regular code. That was the purpose of making it appear as a string. using the quotation marks makes it a proper string, thus no syntax eror . . . so basically, change this:

//now do whatever you want to do with the variable hold...

to this:

eval(hold);


as well, make sure to add another closing bracket since I only included two and three are needed.

@jonavanmonaauthorNov 12.2006 — thats exactly what i need, you're great?

@konithomimoNov 12.2006 — No problem. I should mention though that eval() uses a lot of system proceses, so it can run slow sometimes.

Success!
