I am new Please hellp !!!

can we use something like
y is a variable
out.println(<input type=/'text/' id=/'name"+y+"/'>);
or
out.println(<input type=/'text/' id=/'name<%=y%>/'>);

Actually i want to generate tag id's dynamically for form inputs(which are generating dynamically too) for further value retrieval through javascript.
as

var temp=document.getElementById("name1").value;
var temp1=document.getElementById(name2).value;

Please reply soon. Thanks in Advance

Hi Utkarsh,

Please do you the code tag when putting any code.
Regarding the question.



OR if using the " (double quotes to given the value to properties) then


Note the use of escape sequence \ (its not /)

If you are wrting in JSP then you can also use

Why are you using out.println in the first place? That's really strange. The whole point of a JSP is not to have to create HTML in strings! Just put the HTML in template text.

Also, using Java scriptlets in JSPs is an obsolete practice from over 10 years ago! Time to modernize your skills with the JSTL and EL. Please see this JspFaq entry.
