Convert Java variable to Javascript variable
Hi guys,
This is pretty weird. I'm using BEA workshop 8.1. In my JSP, there is a Javascript which I need to convert a Java variable to Javascript variable.
A section of my codes goes below:
<%
String hsCode = request.getAttribute("hsCo
System.out.println(hsCode)
%>
var JShsCode = <%=hsCode%>;
alert(JShsCode);
In my console, the hsCode is printed out as 0701, but in my alert box when I load the JSP, JShsCode becomes 449. With each different value of hsCode, the JShsCode value changes .e.g. hsCode 077 will alert me JShsCode 63.
Any ideas on this?

Personally, I would output the correct value from the server rather than getting the client to do the call.

Hi guys,
I've tried using the methods mentioned, I've missed this part out earlier in my question. The hsCode 0701 is a number which the user input, which means it could be 334 or 0802 or 0701 or anything (numeric). And I tried using parseInt, but it doesnt retain the 0 in front, as code 0701 is different from 701.
Any idea?

OK guys I've solved it oredi and using '<%=hsCode%>' works fine and retains the leading 0 in front. You guys are cool s**t!
Well, we are Experts anyway!
You could also left trim all leading zeros.
Not sure on the Java method for that.
You could just read 1 char at a time and convert to a space and then not put the quotes in the JS output.
So, (using _ as a space), 0701 ...
var JShsCode = 0701;
becomes (remember using _ as a space) ...
var JShsCode = _701;
Which removes the octal notation marker.
