Twitter Bootstrap styling conflicts with plug-ins like jqGrid and other third part libraries

Issues:The concern with Twitter Bootstrap framework is that some of their css selectors are simply too generic and have incompatibility issues and conflicts with most third party plug-ins and css libraries, like jQuery-UI and jqGrid.My most pressing concern is only with the generic selector for the styling of "INPUT" controls.Some concerns:So basically anyone using BS (Bootstrap) will have to override styling 100% of the time on all input controls on all their web pages for all the plug-ins they ......

Prevent copying images from web page - read-only images

Problem:You have images on your web site that you want to protect from being copied and used. In essence you want to make them "read-only" so to speak.Solution:Add the HTML code by wrapping your image with it.<span oncontextmenu="return false" ondragstart="return false"><img id="your image"/></span>This is not 100% fool proof, am not going to explain why as that would make this post useless :-) ......

jqGrid - dynamically load different drop down values for different rows depending on another column value

Goal: As we all know the jqGrid examples in the demo and the Wiki always refer to static values for drop down boxes. This of course is a personal preference but in dynamic design these values should be populated from the database/xml file, etc, ideally JSON formatted. Can you do this in jqGrid, yes, but with some custom coding which we will briefly show below (refer to some of my other blog entries for a more detailed discussion on this topic). What you CANNOT do in jqGrid, referring here up and ......

Goal: Storing arbitrary data inside the DOM Issue: Storing data : $('selector').attr('alt', 'my data'); Retrieving data: $('selector').attr('alt'); The ALT attribute is designed to be an alternative text description. For images the ALT text displays before the image is loaded. ALT is a required element for images and can only be used for image tags because its specific purpose is to describe images.So therefore, "alt" is an HTML attribute meant to give the tag meaning and not to store data. Also ......
