Servlets & javascript

[Anonymous]

I have a servlet which retrieves a string from the database. Can I pass that string to a javascript variable???
That variable is than sent to the client side to do further processing.

Try something like this in your web page:
<SCRIPT LANGUAGE="Javascript">
var myJSstring = '<%= myJSPClass.getValue() %>';
var myJSnumber = <%= myOtherJSPClass.getValue() %>;
</SCRIPT>

Hi,
One of the methods through which you can access java variables in JavaScript in servlets is through hidden variables.
After retreiving the string from the database, put it as a value for a hidden field using the foll. code :
out.println("<input type=hidden name=fieldname value='"+varname+"'>");
You can access the same in JavaScript for client side validations using document.formname.fieldname.value.
I have used the same in many of my servlets.
See if this helps your cause.
Bye.

hai,
u can take the value of the varialble directly into javascript
like
out.println(" function valchk(){ ");
out.println(" var sampval = " + mservval + " ; ");
.....
or u can directly check like
out.println(" if(document.myhtm.t1.value = '"+mservval+" ) { ");
.
i think this can solve ur problem much
all the best'
