hi all
i am new to js and need some help, after turning every stone i am posting my problem for a solutions from fellow developers.
i have the following code for converting to hex(unicode) its working fine but its converting the text upon submit i need it to convert as the user goes on typing. just like the counter field that is there on the page.
i think its better if u copy the follwing code and then see it in browser to understand my problem.
thanks in advance
