We've done this. We put our javascript code into .js files as
suggested. This is static js code, functions really. Then in our
velocity templates we use the js functions. We really try to keep
these javascript functions to ui issues ( speed ) and very little
logic in them ( for example disabling or enabling a button on the fly
).
So in one instance we had to take a list of objects we get from our
pull tool and slam that into a js array for our javascript functions
to use. In our velocity template we did just that:
--- CommonJS.vm---
<script language="JavaScript"
src="$content.getURI("javascript/selectbox.js")"></script>
<script language="JavaScript"
src="$content.getURI("javascript/format-utility.js")"></script>
#set($jsfields = $layoutholder.Layout.Fields)
#if ($jsfields)
<script language="JavaScript">
var noFields = $jsfields.size();
var fields = new Array(noFields);
#set($offset = 1)
#foreach($field in $jsfields)
#set ($i = $velocityCount - 1)
#set ($end = $offset + $field.FieldLength - 1 )
fields[$i] = new Array(6);
fields[$i][0] = "$formatutil.escapeJavaScript($!field.CustomerField)";
fields[$i][1] = "$!field.QdsField";
fields[$i][2] = "$!field.FieldLength";
fields[$i][3] = "$offset";
fields[$i][4] = "$end";
fields[$i][5] = "$!field.FieldType";
fields[$i][6] = "$!field.FieldFormat";
#set ($offset = $end+1);
#end
</script>
#end
Then we use our javascript function on our html elements, passing the array as needed.
<select name="fmt" size="10" onChange="update(this, fields)"
onkeypress="keyUpdate(this,event)">
Hope this helps.
