An example:
Map<String, CharSequence> variables = new HashMap<String,
CharSequence>(7);
variables.put("javaScriptId", javaScriptId);
variables.put("backGroundElementId", backgroundElementId);
variables.put("imageElementId", imageElementId);
variables.put("leftUp", settings.getLeftUp());
variables.put("rightDown", settings.getRightDown());
variables.put("tick", settings.getTick());
variables.put("formElementId", element.getId());
add(TextTemplateHeaderContributor.forJavaScript(Slider.class,
"init.js", Model.valueOf(variables)));
Where init.js is:
var ${javaScriptId};
function init${javaScriptId}() {
${javaScriptId} =
YAHOO.widget.Slider.getHorizSlider("${backGroundElementId}",
"${imageElementId}", ${leftUp}, ${rightDown}, ${tick});
${javaScriptId}.onChange = function(offsetFromStart) {
document.getElementById("${formElementId}").value =
offsetFromStart;
}
}
