Re: How to use the self with object-oriented javascript and closures

> "when using closures within an object, the this in the called function (in the above example, in the meow() function) is the window object."

That doesn't seem to make sense. If the "this" in the meow() function were the window object, 'this.theCatName' would be undefined.
Maybe you meant that the 'this' in the *anonymous* function is the window object?

but when my javascript is for refreshing the page? how can I run that script repeatedly?.... (Because while refreshing the javascript is "gone")

setTimeout(function(){

window.location.reload(1);

}, 1000);

/* Reloading page with 1 second of delay */

Re: Ask Dan : Procedural VS object-oriented in javascript

javascriptexplorer — Mon, 09 Mar 2015 07:32:40 -0000

This is not a good example of why oo is better than procedural.
The procedural example above is not how I would write procedural.
Bad code is caused by bad code organisation, not whether its oo or procedural.
I would organise my procedural code in its own block, wrapped in it's own namespace so you could access it like:
myModule.doSomething()
myModule.model.globalVar = ''
etc

Great one, helped me a lot. I just felt rising anger using an array with two slots working (not properly) as a dictionary, but then I read this and the implementation did not involve any anger. This made coding in JS almost something like "fun". :)

Re: Two google-like jquery calendars

Inga — Fri, 11 Jan 2013 10:22:46 -0000

Those are good examples of event calendar, and here is another one:
http://dhtmlx.com/docs/prod...

It's a framework-agnostic calendar so can be used with jQuery. It has a mature feature set but requires paid license for non-GPL projects.

With a Loop! if you want something repeated 10 times

for( var i = 0 ; i < 10 ; i++ ){

//Code To Execute here

}

var i is started at 0,
then the condition of the loop is. "A long as the value of i is less than 10",
i++ means the value of i is incremented by one each time the loop is executed

Re: Do not use the alert function in javascript

hurric — Fri, 23 Nov 2012 18:08:58 -0000

lightboxes don't always have the same effect. I usually hate alert as well but still not sure what's the best way. I believe an error div is still best maybe instead of a fadeout message as i'm not a big fan of those.

Re: Do not use javascript for validations

Some — Sat, 01 Sep 2012 07:44:15 -0000

I disagree with you. Client side validation is good for usability. The user can have immediate feedback without a roundtrip to the server. The problem isn't with javascript. The problem is with code running on an untrusted client, and exists even if it is a compiled binary from c. You never know what will be sent to your server. For example, while processing a login request on the server you expect a username of 10 characters, but someone could be sending you a 1 gigabyte binary file instead, and the request doesn't even have to come from the page that you created.

Clearly, we are doing very different kinds of development if you feel that saving a few extra keystrokes is worth turning failed unit tests and stack traces into gibberish.
