hi, because of my ignorance in DOM, I started mixing jquery (one of the
simplest javascript libraries) and mapbuilder and found a very simple
solution to this problem, modifying WidgetBaseXSL.js [thanks Denton for you
tutorial ;.) ].
If the response of GetFeatureInfo widget goes to a tag with id="left", we
can count how many responses are appended there and restrict the number of
these. If the number of responses are greater than x, then delete the
content of "left" and append the new response there.
Very very simple but works. I think mixing jquery (or anyother js
library) inside of the mapbuilder code can give great oportunities for
"playing" with the DOM, css, etc. In the case of modifying WidgetBaseXSL,
You just must add mapbuilder.loadScript(baseDir+"/tool/jquery.js"); after
mapbuilder.loadScript(baseDir+"/widget/WidgetBase.js");
if (widgetNode.nodeName != 'FeatureInfo') {
objRef.node.appendChild(tempNode.firstChild);} else {
$("#title").html("<th>getFeatureInfo responses are:</th>");
new=document.getElementById('left');
var childs=new.childNodes;//alert("numero childs :"+childs.length);
if (childs.length > 1) {
$("#left").empty();
//$("<div><h2><p>Resultats amb major de
1</p></h2></div>").appendTo("#left");
objRef.node.appendChild(tempNode.firstChild);
}else {
objRef.node.appendChild(tempNode.firstChild);
objRef.postPaint(objRef);
