We can call javascript from XForm using xform:load tag. The following example calls the javascript function named helloscript.

      <xforms:trigger>
        <xforms:label>Launch JS</xforms:label>
        <xforms:load resource="javascript:helloscript()" ev:event="DOMActivate"/>
      </xforms:trigger>

function getElementsByClass(searchClass,node,tag) {
var classElements = new Array();
if ( node == null )
node = document;
if ( tag == null )
tag = ‘*’;
var els = node.getElementsByTagName(tag);
var elsLen = els.length;
var pattern = new RegExp(“(^|\\s)”+searchClass+”(\\s|$)”);
for (i = 0, j = 0; i < elsLen; i++) {
if ( pattern.test(els[i].className) ) {
classElements[j] = els[i];
j++;
}
}
return classElements;
}
