How do I change HTML objects with my JS strings ?

Ok, heres the deal ;

I have my script code like this

var v = "place";
for (var i = 0 ; i < 5 ; i++)
{
v = v + i; // or v = "place" +i;
// Here I want to access the resource in the HTML doc, whos id="place1",
id="place2", etc etc, so how can I do that ?
// like "theValueInv".innerText = "bla bla bla bla"; if the resource
with id="place1" is for ewxample a <p>
}


I hope you clever guys can help this newbie with this ...
TIA

You want 'v = "place" +i;'. What you have here will give you "place1",
"place12", "place123", etc.

var elem = document.getElementById(v);

You can use innerText, but that only works in IE and Opera 7. Or you
could use DOM methods that works in all modern browsers (for IE, here
that means IE 5+)

// clear old content
while(elem.hasChildNodes()) {
elem.removeChild(elem.lastChild);
}
// add new
elem.appendChild(document.createTextNode("bla bla bla bla"));

Look at:-

-and the linked resource.

But if your interest is on locating elements within a document that have
a specific (and unique, as required) ID then the document.getElementById
function is probably the best option:-

function getEl(id){
if(document.getElementById){ //all DOM browsers
return document.getElementById(id);
}else if(document.all){ //IE 4 fall-back
return document.all[id];
}else if(document.layers){ //Netscape 4
return document.layers[id];//but that will only find positioned
//elements on Netscape 4.
}
return null; //no suitable method exists on this browser.
}

....
var el, v = "place";
for(var c = 0;c < 5;c++){
el = getEl(v+c);
if(el){ //so only if the returned value was non-null.
... //do something with the element.
}
}
....
