3 special features of jQuery

Author - Richa

1. Fetching coordinates of current location of the mouse:

Below is the code to retrieve the coordinates of the mouse at any position on the webpage and display inside a div with id getCoords:

<script>
$(document).ready(function()
{
$(document).mousemove(function(e){
$('#getCoords').html("X: " + e.pageX + " and Y :  " + e.pageY);});
});
</script>
<div id=getCoords></div>

2. Using data() method to attach some data to an element:

Use of data() function is to attach/store an information into an element. To set the value, we need to pass two values, that is, a key and a value pair.
To retrieve the stored value, we call the data() function by passing key of the required value. Below is the sample code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js">
</script>
<script>
$(document).ready(function(){
   $("#button1").click(function(){
   $("#show").data("sometext", "Welcome user!!"); // stores data in show div having key as ‘sometext’
   });
   $("#button2").click(function(){
   $("#text1").text($("#show").data("sometext")); // fetches data in text1 div using the key});
   });
</script>
</head>
<body>
<button id="button1">Click to attach text in hidden div</button>
<button id="button2">Click to view welcome text</button><br>
<br>
<div id="text1"></div>
<div id="show"></div>
</body>

3. Disabling right mouse click on a webpage:

Many times, we come across a requirement to disable the right click feature on our webpage. To achieve this functionaligoodty, below code can be used:

$(document).ready(function(){
$(document).bind( "contextmenu", function(f){
return false;
});
});
