How to pass more than 1 parameter using location.href

I would like to know how to pass more than 1 parameter/value using location.href

eg: below is only 1 parameter
onchange='location.href=‘second.jsp?field1=’+this.value"

First, you have some quote problems.

Second, you aren’t using location.href to pass values, you’re using the url to pass values. The url you specify for location.href will load in the window. The page that loads can then pick out the values that are attached to the end of the url. Multiple values are separated by the symbol “&”:

second.jsp?field1=10&name=Sally

i.e.
econd.jsp?field1=10&name=Sally

<select onchange=“location.href='second.jsp?field1=”+this.value+“&name=Sally+”'">
…</select>
The end has a double quote, single quote, and double quote again.

Cheers.
