regarding cross-browser functionality or compatibility?

Hi Ranchers,

Prototype, dojo, jquery or may be other frameworks, enables you to deal with Ajax calls in a very easy way and it is also deal with cross-browser complaint.

My Question is,
what type of techniques they used in the liabraries to make it compatible with others browers?

Thanks,

I would say look at the source code, they have comments.

Ill guess that feature-sensing has to be one of the techniques, if not the only technique.

Thanks for your quick reply Eric,

I am going to look these libraries source code (i don't know whether i can understand it or not) but can you give me any example of it.

Thanks in Advance.

Yeah it may be..

is this like creating a XMLHttpRequest Object with other browser supported methods if it not supported this JavaScript Object.

You will need to understand OO javascript as it is used in the libraries.

Yes, it is like that.

You can ask javascript if a feature is supported.

Like,

if aaa
<do it IE way>
else if bbb
<do it Firefox way>
else
<for some reason, like very old browsers, no such feature supported>
endif
endif

Thanks Jesus,
this is what I am looking for...

another way is to use the try{} instead of 'if'

just like in java
