Ajax replacing javascripts in responseText

[vindex]

Hello everyone.

i'm constructing a multi-language supporting webpage.
every piece of text is put in a large javascript array which is called by the user when opening the webpage. so far so good.

when I now use an Ajax-function to change the content of a certain <div>, which's content is in an external.php (in fact, ajax changes this php),
i want to make this change appear directly to the viewer (me) without reloading.

so i call again Ajax to get the content of this external.php to re-place it into the <div>.

but the problem now: by doing this, the language-support functions are not evaluated.

every text-piece in the source code looks like this:

<script>document.write(lang[int]);</script>

where "int" is the reference to the special text-element.

i tried to replace the <script>'s with the array's content using this:

body = xmlhttp.responseText;
body = body.replace(/<script>document\.write\(lang\[(.+?)\]\)\;<\/script>/, lang[$1] );

but it doesnt work. i tried

"lang[$1]"  //it replaces the string "lang[$1]" with the right integer as $1
lang[$1]   //it says $1 not defined (of course...)
lang["$1"]  //it replaces with "undefined" because lang["$1"] doesnt exist 

i hope you'll understand my problem =/

is there maybe a better way to enforce the source-code from responseText to first evaluate its javascripts before placing into the <div> ?

best wishes

okay.. after what felt like hours, i made a workaround, it's prolly not the best solution, but it works for my need

[HTML]function eval_body(text) {
var tempmsg;
var pattern = /<script>document\.write\(lang\[(.+?)\]\)\;<\/script>/;
var ar;

while(ar = pattern.exec(text)){
tempmsg = lang[ar[1]];
text = text.replace(pattern, tempmsg);
}
return text;
}[/HTML]


sorry to have bothered you,

best regards, vindex

Surely, it'd be better to return the output via PHP rather than parsing/eval-ing the response.
