I have a question using grails variable values in javascript code in a GSP file.
For Example: I have a session value session.getAttribute("selectedValue") and I want to use this value inside javascript code part.
My solution is now (inside a GSP):
<%
def js = new String("<script type=\"text/javascript\">")
js += "var jsSelectedValue = " + session.getAttribute("selectedValue") + ";"
js += "</script>"
out << js
%>
and then I have javascript block inside my GSP with jQuery Stuff and so on, there I need this value.
Is there another way to have grails variables accessible inside pure javascript code?
And second question, the exactly other way around. I select for example in a dropdown box and click "save" and then i want to store the value $("#select-box").val() inside a session variable from JS-part.
Thank you very much in advance for your help.
Cheers,
Marco
Why do not use the javascript GSP-tag? A solution can look like this:
<g:javascript>
var jsSelectedValue = "${session.selectedValue}";
</g:javascript>
