copied!<p>I have been using the following utility function that I wrote a long time ago:</p> <pre><code>/** * @classDescription This class contains different utility functions */ function Utils() {} /** * This method returns a delegate function closure that will call * targetMethod on targetObject with specified arguments and with * arguments specified by the caller of this delegate * * @param {Object} targetObj - the object to call the method on * @param {Object} targetMethod - the method to call on the object * @param {Object} [arg1] - optional argument 1 * @param {Object} [arg2] - optional argument 2 * @param {Object} [arg3] - optional argument 3 */ Utils.createDelegate = function( targetObj, targetMethod, arg1, arg2, arg3 ) { // Create an array containing the arguments var initArgs = new Array(); // Skip the first two arguments as they are the target object and method for( var i = 2; i < arguments.length; ++i ) { initArgs.push( arguments[i] ); } // Return the closure return function() { // Add the initial arguments of the delegate var args = initArgs.slice(0); // Add the actual arguments specified by the call to this list for( var i = 0; i < arguments.length; ++i ) { args.push( arguments[i] ); } return targetMethod.apply( targetObj, args ); }; } </code></pre> <p>So, in your example, I would replace </p> <pre><code>function Field1_Changed(el) { Field_Changed(el, delegate(Agent().Field1_Changed, $j(el).val()), true); } </code></pre> <p>With something along the lines</p> <pre><code>function Field1_Changed(el) { Field_Changed(el, Utils.createDelegate(Agent(), Agent().Field1_Changed, $j(el).val()), true); } </code></pre> <p>Then, inside of <code>Agent().FieldX_Changed</code> I would manually call <code>getApplicationState()</code> (and encapsulate that logic into a generic method to process field changes that all of the <code>Agent().FieldX_Changed</code> methods would internally call).</p>
