hello, how can i write a text on web page with javascript:

In javascript you use document.write():
<script type="text/javascript">
document.write("blablalbal");
</script>

Yes the problem with document.write is that it only works as you may
expect before the whole page is loaded (and the DOM Tree is still to be
completed). That's why document.write and print (in PHP) works pretty
much the same way and are only used when generating the page.

To add text to the page after the page is loaded is another problem.
There are several ways to accomplish this but one of the easist one is
to use the innerHTML-property that every HTML-element has:

document.getElementById("elementID").innerHTML = "TExt";
or
document.body.innerHTML += "text"; // adds the text directly to the
body-element

You shouldn't try this method before the whole page is loaded though.
The element you try to add the text to might not be comlete yet.

Read FAQ 4.15 for that.

Please use a properly informative Subject line.

Replacing the body.innerHTML will have pretty much the same effect as
using document.write() - the current content will be obliterated.

Much better to use DOM methods to create the required elements and
append them to appropriate nodes. innerHTML, though widely supported,
is not a W3C standard and is most useful for replacing the content of
an element with some other (reasonably simple) content.

To the OP: research 'createElement'.
