Checkbox Onclick "add to list"?

Checkbox Onclick "add to list"?

Hi Zoho,

I have a checkbox on my html page, and when its checked I'd like to add its value to a List I've created before.
Right now this is the script:

htmlpage test_page(VarListParam)
displayname = "test page"
content
<%{
    List = {"Bike", "Car", "Motor","Helicopter"};
  VarList = List();%>
  
<form action=""  method="get" >
  
  <%for each EachVeh in List
    {%>     <input type="checkbox" name="vehicle" id="myCheck" value=<%=EachVeh%>onclick=VarList.add(EachVeh)>I have a <%=EachVeh%><br>    <%}%>
        
<input type="submit" value="Submit" >
</form>  

<%}%>


When I click on "Sumbit" I get the vehicle values on the URL, but not in the "VarList" list - as a parameter, and before the #Page - so I can't even use them :(

If I make "Car" and "Bike" I get :

https://app.zohocreator.com/USERNAME/APPNAME/?vehicle=Car&vehicle=Bike#Page:test_page?


Now, basically I just need the list of vehiles chosen (in this case- "Car,Bike").
the string added to the URL (" ?vehicle=Car&vehicle=Bike") will totally suffice also.

Any idea how I can get those?


Thanks

Ravid
