Feature: Function call on focus

[GoogleCodeExporter]

I'd like a feature that assigns a function to be called before editing begins, 
to get a value for the text that might differ from what is being displayed.

Consider the web page text: "yolk and sugar"

The original text was: "i1 & i2" (where i1 and i2 represent yolk and sugar).

In other words, the text on the web page is an expansion of their original, 
abbreviated text. The only way to retrieve the original text is by sending a 
request to the server.

Something like:

on_edit (function) default: null. Called before editing begins.

Made a few changes to jquery.inline.js:

In function setInitialValue, around line 284 (before editor.val(initialValue)):

    if( this.settings.on_edit ) {
      initialValue = this.settings.on_edit( initialValue );
    }

And at the top of the source, around line 81:

  on_edit:      null, // function: called before editing begins

Then write a function:

function getEditValue( initialValue ) { 
  return "42 " + initialValue;
}

Seems to do the trick.

A full example:

  $('.span-class').editInPlace({
    url           : window.location.pathname,
    default_text  : '',
    hover_class   : 'inplace_hover',
    params        : 'command=update-instruction',
    on_edit       : get_instruction_value
  });

Then this line can become a bit more flexible:

  initialValue = this.settings.on_edit( this.dom, initialValue );

And then the <span> element (or whatever was DOM element was used) is passed 
along:

  function get_instruction_value( dom, initialValue ) {
    return "id: " + dom.attr("id") + " " + initialValue;
  }
