Strange behavior using HTML ‘readonly=”readonly”‘ vs. JavaScript ‘element.readOnly = true;’

by

Some background So I was finishing up some enhancements in a web application that does some automatic interpolation of data. There are a handful of textboxes that the user fills out, and other textboxes in between them have values automatically calculated. The textboxes that receive automatically calculated values must be readOnly to prevent user changes, … Read more

Workarounds to access the Readonly Textbox value on server side when changed through client side script

And provided a calender java-script plug-in which sets the Textbox value. Now when I am trying to access the date Textbox on save click, the Textbox value is not persisted.

Read/Write Python Closures

Closures are an incredibly useful language feature. They let us do clever things that would otherwise take a lot of code, and often enable us to write code that is more elegant and more clear. In Python 2.x, closures variable names cannot be rebound; that is, a function defined inside another lexical scope cannot do something like some_var = 'changed!' for variables outside of its local scope. Can someone explain why that is? There have been situations in which I would like to create a closure that rebinds variables in the outer scope, but it wasn’t possible. I realize that in almost all cases (if not all of them), this behavior can be achieved with classes, but it is often not as clean or as elegant. Why can’t I do it with a closure?
