It’s quite easy to use JavaScript variables in jQuery selectors.
Let’s seen an example to use JavaScript variables in jQuery to hide an element:
<!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("input").click(function(){ var name = this.name; $("input[name=" + name + "]").hide(); } ); }); </script> </head> <body> <h1>Heading 1</h1> <input type="text" id="bx"/> <input type="button" name="bx" value="one"/><br> <input type="text" id="by"/> <input type="button" name="by" value="two"/> <p>To hide the buttons, click on it.</p> </body> </html>
