Does dhtmlxAjax have support for Ajax error handling. For example, if the server code crashes, how do we know an error occurred? I have a servlet based server, which I can use to return various status codes. Does dhtmlxAjax allow me to check these codes, and perform appropriate client-side actions?
When used separately dhtmlxAjax doesn’t provide any special error handlers, but you can use
dhtmlxAjax.get(url,function(result){
if (!result.xmlDoc.responseXML) alert(result.xmlDoc.responseText); //if xml is not valid - output response
else{
//default action
}
});
more complex validation can be organized as
dhtmlxAjax.get(url,function(result){
result.getXMLTopNode(“name_of_top_node”);
//default action
});
dhtmlxError.catchError(“LoadXML”,function(type,description,details){
alert(details[0].responseText);
///code here will be called for all xml loading errors
})
