In this post of JQuery, I will introduce you to id selector. The syntax of id selector is particular element’ attribute id value prepended by ‘#’ symbol, for eg #button.
It is used to select one particular element whose id matches the id given in the $ method.
Below is an example
1 <html>
2 <head>
3 https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js
4 </head>
5 <body>
6
7 function c() {
8 var $button = $('#button');
9 alert($button);
10 }
11
12 <input id="button" name="button" type="button" value="button" onclick="selectElement();"/>
13 </body>
14 </html>
In the above html code, on click of button I am calling javascript selectElement method.
In the javascript method at line 8, I am selecting all the elements having id “button”, in the case of this example only one element has id ‘button’.
