Re: Best way to deal with Javascript (in)compatibility using PHP?

Hello,

We would be interested in hearing about the way people deal with
javascript browser compatibility using PHP. There must be some much
simpler ways of doing this but we are not sure how to do it.

Often is not a matter of dealing with browser differences but also different Javascript versions in different versions of the same browser.

The most reliable way to solve that problem is to provide alternate Javascript code that is conditionally executed at Javascript run time depending on what the browser supports.

That is the solution used by this form validation class for instance to validate e-mail addresses. If the regular expression objects are available, it uses them, otherwise it uses a more basic type of e-mail address validation:

http://www.phpclasses.org/formsgeneration


if(s.search)
{
	return (s.search(new RegExp('email-regular-expression','gi'))>=0)
}
else
{
	some other type of basic validation;
}

Regular expression detection support is made checking the existence of the search method in the string object.
