I'm trying to integrate analytics into my GWT application. To do this,
I'm calling a service that returns a String of HTML that needs to be
parsed and eval'ed. The following seems to work to eval() the contents
of a <script> tag, but it fails (silently) if I try to parse a .js
file (referenced in a "src" attribute). Any ideas why?
Thanks,
Matt
try {
evalJS(new HTML(response).getElement());
} catch (JavaScriptException jse) {
GWT.log("Failed to parse analytics scripts.", jse);
GWT.log("Analytics script contents: " + response,
null);
}
public static native String evalJS(Element e) /*-{
var scripts = e.getElementsByTagName("script");
for (i=0; i < scripts.length; i++) {
// if src, eval it, otherwise eval the body
if (scripts[i].hasAttribute("src")) {
eval(scripts[i].getAttribute("src")); // silently
fails here
} else {
eval(scripts[i].innerHTML); // this works
}
}
}-*/;
