[Resolved] php/javascript question

jlpierce

I want to know if it is possible to generate a javascript variable or array with php, but on the same page use a funtion declared in an included javascript file to act on the said var or array.

basically:

<head>
<script  language = "javascript">
myarray = new array();
//populate myarray with data from php here!
</script>

<script language = "javascript" src = "func.js"> </script>
</head>

// based on an event (onClick) for example
// I want to call a function from func.js and use
// it to manipulate the array myarray.

I do not want to litter every page of the program with javascript when I can store them in a file.

TIA

You could always try it, I suppose.....

sure you can do that.

what about putting the javascript into a .php file that you include?

example:
js_file.php:

<?php
function func_generate_jsarrays(){
//getting back data from DB and putting it into javascript arrays:
for($x = 0; $x < sizeof($arr_dbanswer); $x++){
echo "var_array_$x = new Array(\"$arr_dbanswer[0]\",\"$arr_dbanswer[1]\",\"$arr_dbanswer[2]\",);";
}
}
?>

including file(s)
<?php
include("../js_file.php");
?>
<script language=javascript>
<!--

<?php func_generate_jsarrays(); ?>

//some javascript stuff

ans so on...

javascript is just clientsided code like html, so you can write it with php. you only have to keep in mind what is client- and what is serversided.

hope this helps.

Thanks, I have gotten that part to work, but I am having trouble calling a javascript function that is in one file from a javascript function that is in another file.

Both files are included in the head of the html document.

hmm...
i think i lost you now...
if you write the script part into your output file with php youll have the function in the page you call it...

the way i thought at least...

as to calling functions in other frames:
since functions are bound into the dom via the "function" object they do behave the same way all other things do, therefor you call it the same way you do it with other objects in dom:

<a href="javascript:parent.frames[n].func_on_buttonclick();">...

stupid question:
have you made a functional model for your scripts, meaning do you have a clear idea of what should happen in which script?

if not i'd take a sheet of paper and do that before you work further....
if you dont now youll do it when you make the first functional changes, and then its thrice the effort... (hinthint)
as i had to learn the hard way. sighs

if you try it youll see that you wont have half the trouble with programming the stuff that you have without...

well. never mind.
hope this helps you.
if not, ask. 🙂

js = client side
php = server side

the flow to accomplish this would be

generate a php page with the js on it and have the js fill out a form and submit it back to the php then php can get the form variables.
