depends on what you call youre back button if it is an html button with that function as event it should work . if you are trying to control a browser button that wouldnt work at all

Javascript isn't set up to save users data.

thanks for your reply. my problem is, I have designed a form which takes data like name, contact number, e-mail etc from users. if users enter wrong e-mail and submit the form, it validates the form data and gives "back" link to correct wrongly entered data.

Incorrect e-Mail address. Please go <a href="javascript:history.back();">back</a> and enter the e-Mail address correctly

 

when i click the "back" link, all of the form data was gone. how can i make retain the form data when clicked the back link.

 

data is retained when going through browser's back button. but not with javascript:history.back method

 

any ides??

 

 

thanks again.

Try have the validation on the same page as the form, and set action to server self. That way, no "back" will be needed.

this is not really a javascript issue what you really need is serverside validation. when certain fields are empty or incorrect you should retrieve the posted data and show the form again. this is php related.

 

you can validate your form using javascript however you should always use serverside validation and javascript to create a more user friendly experience. look up php form validation tutorials

Along with that, if user has Js disabled, that data will go (into database or whatever you doing with it) unvalidated.
