[RFC|Merged] Get rid of eval in javascript

[brunoais]

Ticket: http://tracker.phpbb.com/browse/PHPBB3-11008
Patch: https://github.com/phpbb/phpbb3/pull/904

Intorduction
One of the things that we are getting rid of is the function eval() in the phpBB php core. But I still can't find if you are planning to get rid of eval in js too.
My proposal is to remove all eval in javascript.

The problems that stands out
The first this that stands out is the

Code: Select all

eval(onload_functions[i]);

and the 2nd thing that stands out is

Code: Select all

eval(onunload_functions[i]);

. Both are two very negative things to have in a forum like this one.
I'll also leave the third that stands out.

Code: Select all

eval('parent = document.' + id);

.

What to do, then?
My proposal is to get rid of all these needless eval() (all eval that I found don't even need to be there).
The easiest to show what I mean is use:

Code: Select all

parent = document[id];

instead of:

Code: Select all

eval('parent = document.' + id);

.
The

Code: Select all

eval(onload_functions[i]);

can easily be changed to execute anonymous functions in the array, etc, etc...

-> If this is accepted I can do that job myself.

Proposed to appear in phpbb 3.1 or in a next phpbb 3.0.*

There's a ticket somewhere for this. The entire piece of code will be binned with the introduction of jQuery, as jQuery handles executing stuff on load:

Code: Select all

$(function () {
    // Do stuff
});

Hum... I can't find the ticket. How is it called?

[callumacrae]

Not sure, I can't find it.

eval is still being used in a number of places, but this really should be made a ticket on the tracker. Please create one and link to it from here.
