Of course, you can still make use of jQuery, easily by writing the complete name rather than the shortcut. Coding of this jQuery script is mentioned below:

jQuery(“button”).click(function(){
jQuery(“p”).text(“jQuery is still working!”);
});
});

/*

do something now that the script is loaded and code has been executed

*/

});

3.       Make and get back nested objects with jQuery

You can as well create nested objects with jQuery and also retrieve them. In this, you can put in the functionality to the object of jQuery. The JavaScript of jQuery is the equivalent method to get and set. You will make use of an obj method in this case. A coding is mentioned below:

__________________________________________________________________________________________

function() {

// Utility method to get and set objects that may or may not exist

var objectifier = function(splits, create, context) {

var result = context || window;

for(var i = 0, s; result && (s = splits[i]); i++) {

result = (s in result ? result[s] : (create ? result[s] = {} : undefined));

}

return result;

};

// Gets or sets an object

jQuery.obj = function(name, value, create, context) {

// Setter

if(value != undefined) {

var splits = name.split(“.”), s = splits.pop(), result = objectifier(splits, true, context);

return result && s ? (result[s] = value) : undefined;

}

// Getter

else {

return objectifier(name.split(“.”), create, context);

}

};

})();

4.       Get ready.$(document).ready()

With this, you can queue up a line of events and have them implement after the DOM initialization. Coding is mentioned below:

alert(‘Hello World’);

});
