+ * Bidirectional-streams Over Synchronous HTTP (BOSH) to emulate
|

|
|
|
+ * Bind a function to an instance.
|
|
|
+ *
|
|
|
+ * This Function object extension method creates a bound method similar
|
|
|
+ * to those in Python. This means that the 'this' object will point
|
|
|
+ * to the instance you want. See
|
|
|
+ * <a href='https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind'>MDC's bind() documentation</a> and
|
|
|
+ * <a href='http://benjamin.smedbergs.us/blog/2007-01-03/bound-functions-and-function-imports-in-javascript/'>Bound Functions and Function Imports in JavaScript</a>
|
|
|
+ * for a complete explanation.
|
|
|
+ *
|
|
|
+ * This extension already exists in some browsers (namely, Firefox 3), but
|
|
|
+ * we provide it to support those that don't.
|
|
|
+ *
|
|
|
+ * Parameters:
|
|
|
+ * (Object) obj - The object that will become 'this' in the bound function.
|
|
|
+ * (Object) argN - An option argument that will be prepended to the
|
|
|
+ * arguments given for the function call
|
|
|
+ *
|
|
|
+ * Returns:
|
|

|

|
|
|
+ * This object provides an interface similar to JQuery but for building
|
|
|
+ * DOM element easily and rapidly. All the functions except for toString()
|
|
|
+ * and tree() return the object, so calls can be chained. Here's an
|
|
|
+ * example using the $iq() builder helper.
|
|
|
+ * > $iq({to: 'you', from: 'me', type: 'get', id: '1'})
|
|
|
+ * > .c('query', {xmlns: 'strophe:example'})
|
|
|
+ * > .c('example')
|
|
|
+ * > .toString()
|
|
|
+ * The above generates this XML fragment
|
|
|
+ * > <iq to='you' from='me' type='get' id='1'>
|
|
|
+ * > <query xmlns='strophe:example'>
|
|
|
+ * > <example/>
|
|
|
+ * > </query>
|
|
|
+ * > </iq>
|
|
|
+ * The corresponding DOM manipulations to get a similar fragment would be
|
|
|
+ * a lot more tedious and probably involve several helper variables.
|
|
|
+ *
|
|
|
+ * Since adding children makes new operations operate on the child, up()
|
|
|
+ * is provided to traverse up the tree. To add two children, do
|
|
|
+ * > builder.c('child1', ...).up().c('child2', ...)
|
|
|
+ * The next operation on the Builder will be relative to the second child.
