How to pass values from client side to server side ?

Question

Hi All,

I got a situation to transfer values from jsp to servlet's action class. Previously we did it using

<input type="hidden" id="name" value="manoj" />

we take this value in action class by request.getParameter("name"). But now we couldn't pass value like

"Hi\n
 i am\n 
 Manoj". 

Since it has new line included in the string we couldn't take it like this to action. So how I can take value like this to action or is there any way other than hidden input?

Thanks .

Answer 1

You have to escape the newline character if you want to include it from a hidden input field. You can either escape the field value using html character code references or URL encoding the field value.

The value for a new line should be 
 and for a carriage return 


Other alternatives are

• You could save the value of the parameter as to a session attribute or to a cookie and not pass it as a http parameter at all
• You could include the value in a textarea that is hidden using CSS
• You could include the value somewhere else in the document and include it to the form during the onsubmit handler (yuck)
