I came across a lot of articles and discussions by Marc D Anderson and Steve Workman regarding performance gains using .filternode()
. I also read an article by Steve Workman
I also tried to understand the test cases provided in particular this
I was unable to interpret it completely though. I am extensively using SPServices
for SharePoint 2010 even when it might be good to use built-in JavaScript Client Object Model.
I would like to get a few pointers and sample code on
Scenarios in which SPServices and in particular .filternode() should be effectively used
and
Whether it is a good practice to use SPServices even when job can be accomplished using in-built JS.
Also I would like to know what happens behind the scenes while using filternode (How the performance gain is achieved). When we write this:
jQ17(xData.responseXML).find('*').filterNode('z:row').each(function()
{
});
Does 'z:row' indicate "till the last row" or we can use some other character in place of z
