jQuery wrapper

I wrote a set of small jQuery wrappers that look like: var defaultSiteUrl = 'https://default.site.url/pages/site/'; jQuery.getItems = function(options){ options = $.extend({ site:defaultSiteUrl, list:'', query:'<OrderBy><FieldRef Name="ID" Ascending="TRUE" /></OrderBy>', limit:1000, fields:'' // syntax: [{title:'Title',internalName:'LinkTitle'}] },options); var theList = jP.Lists.setSPObject(options.site, options.list); if(options.fields != '') theList.ViewFields = options.fields; options.callback(theList.getSPItemsWithQuery(options.query, options.limit).Items); }; So you can run a query like: $.getItems({ list:'Projects', limit:3, fields:[{internalName:'myField',title:'myField'}], query:'<OrderBy><FieldRef Name="ID" Ascending="FALSE" /></OrderBy>', callback:function(result){ if(!result) alert('no projects found!'); else{ for(property in result) alert(result[property].myField); } } }); Granted, arguably this is more lines than you would need to run this same query normally in jPoint, but I like the flow it has and it's easier for me to remember object properties than syntax, plus I can handle errors the same way globally for all operations of a certain type, or focus them locally to each callback function when needed. Just thought I'd throw this out there for any use/opinions/possible improvements.

Apparently I'm missing something with formatting, hopefully someone can clean this up for me :[

I like your method.  I will need to use it, possibly on my next project, to think about the pros and cons.  I've been thinking about using Aspect Orient Programming to be able to "insert" a error handler globally.  I was able to run your code, and got the same thing, no results.  I noticed, in Firebug, I was getting HTTP 500 errors and a web response saying the GUID was in the wrong format.  I'll need to look more into this.  If anybody else knows or has an idea here, please let us know.
