    Instantiate  – First Spring instantiate the bean.   Populate properties - Spring Inject the bean’s properties.   Set Bean Name - Spring set bean name. if the bean implements  BeanNameAware , spring passes .The  bean’s id to  setBeanName()  method. Set Bean factory -If Bean implements BeanFactoryAware  ,spring passes the beanfactory to           setBeanFactory() . Pre Initialization -  It also called postprocess of bean . if there are any bean BeanPostProcessors,  Spring calls postProcesserBeforeInitialization ()  method. Initialize beans -   If the bean implements IntializingBean ,its afterPropertySet()  method is called. If the bean has init method declaration, the specified initialization method is  Called. Post Initialization -  If there is  BeanPostProcessors , is implements , spring calls their  postProcessAfterinitalization() method.   Rea...

.toggleClass() Returns:  jQuery .toggleClass(className) className   One or more class names (separated by spaces) to be toggled for each element in the matched set. .toggleClass(className, switch) className   One or more class names (separated by spaces) to be toggled for each element in the matched set. switch   A Boolean (not just truthy/falsy) value to determine whether the class should be added or removed. .toggleClass(function(index, class), [switch]) function(index, class)   A function that returns class names to be toggled in the class attribute of each element in the matched set. Receives the index position of the element in the set and the old class value as arguments. switch   A boolean value to determine whether the class should be added or removed. Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the switch argument. This method takes one or more class na...

. removeProp() Returns:  jQuery .removeProp(propertyName) propertyName   The name of the property to set. Remove a property for the set of matched elements. The  .removeProp()  method removes properties set by the  .prop()  method. With some built-in properties of a DOM element or  window  object, browsers may generate an error if an attempt is made to remove the property. jQuery first assigns the value undefined  to the property and ignores any error the browser generates. In general, it is only necessary to remove custom properties that have been set on an object, and not built-in (native) properties. Note:  Do not use this method to remove native properties such as checked, disabled, or selected. This will remove the property completely and, once removed, cannot be added again to element. Use  .prop()  to set these properties to  false  instead. Example   Demo Set a numeric property on a paragraph and then rem...
