JavaScript [ExtJs3]: GridPanel state restore Issue



Found a defect in ExtJs 3.3.0 for GridPanel state restoring which had reported on sencha forum.
There was couple of fix suggested but below one worked for me. 


//http://goo.gl/5tVV7
Ext.override(Ext.grid.ColumnModel, {
    setState: function (col, state) {
        Ext.apply(this.lookup[col], state);
    }
});

ERROR: Ignored call to 'alert()'. The document is sandboxed, and the 'allow-modals' keyword is not set.

Recently I found this issue while writing code snippet in "JSFiddle". And after searching, found this was happening because of new feature added in "Chrome 46+". But at the same time Chrome doesn't have support for "allow-modals" property in "sandbox" attribute. Chromium issue for above behavior: https://codereview.chromium.org/1126253007 To make it work you have to add "allow-scripts allow-modals" in "sandbox" attribute, and use "window.alert" instead of "alert". <!-- Sandbox frame will execute javascript and show modal dialogs --> <iframe sandbox="allow-scripts allow-modals" src="iframe.html"> </iframe> Feature added: Block modal dialog inside a sandboxed iframe.

CSS Specificity

    Many time different CSS rules overlap on one or more element. And some people always get confuse about, which rule will take higher priority then other and why? CSS Specificity is the answer of all these kind of questions. As the name suggest, the CSS rule which is more specific to the element will take higher priority then other. Means something like “#some_id{}” will always take higher priority then “*{}” universal selector.  And if duplicate rules are define then the last rule will be applied to the element. The following list of selectors is by increasing specificity: Type selector (e.g., div) and pseudo-elements in selector (e.g., :after) Class selectors (e.g., .some_class), attributes selectors (e.g., [type=”radio”]) and pseudo-class selector (e.g., :hover) Id selectors (e.g., #some_id) ID takes higher priority then Class, Type and Universal selector (Note: Universal selector has no effect on specificity, see below special conditions).  If d

Application Design Notes

Don’t be afraid to write your own code, but be absolutely sure you need to Don't reinvent the wheel Learn more about your libraries and take full advantage  Date time calculation is hard ( leap second ,  leap year ), use trusted library  js-joda ,  momentJs ,  joda (java) Simple is better than perfect (nearly) every time If you can deliver a sub-optimal solution (that solves the problem but has known limitation) in a week instead of a full featured one in a month DO, IT Simple system are Easy to reason about  Easy to debug Easy to refactor Easy to learn Simple doesn't mean you skip good engineering, but you can use duct tape. Build things the right way from the start, refactoring is hard and expensive Security Manage and store passwords securely Cutout unimportant corners Common retrofitting "grunt work" Internationalization + localization Factoring and styling HTML UI Adding unit test to an existing codebase LOG LOG LOG Log, but do it right We spend lot of time readi
