Question

i am trying to develop a web app which requires the validation in such a way that when the page loads i would have a single drop down select box enabled and rest of the things such as textbox,buttons all should be in disable mode. when i would select the item from the first select box,then only the other text box should enabled.

after i am done with selecting all the fields, then only the submit button should be enabled.

please suggest me the way in javascript or provide any code snippets so that i can design efficiently.

Answer 1

Ok every select box has onchange attribute which fires a function and in that function you can write to enable your text boxes and any thing else you want

<select onchange = 'func();'></select>

after that text boxes has onkeypress attr which will fire function in that you can write to enable sumbit button

<input type='text' onkeypress="func();"/>

In this function you can check whether all text boxes are filled or not and than you can enable your submit button..
