JQuery A Brief Look

A Brief Look

DOM Traversal and Manipulation

Get the <button> element with the class 'continue' and change its HTML to 'Next Step...'

$( "button.continue" ).html( "Next Step..." )

Event Handling

Show the #banner-message element that is hidden with display:none in its CSS when any button in #button-container is clicked.

var hiddenBox = $( "#banner-message" );
$( "#button-container button" ).on( "click", function( event ) {
 hiddenBox.show();
});

Ajax

Call a local script on the server /api/getWeather with the query parameter zipcode=97201 and replace the element #weather-temp's html with the returned text.

$.ajax({
 url: "/api/getWeather",
 data: {
 zipcode: 97201
 },
 success: function( data ) {
 $( "#weather-temp" ).html( "<strong>" + data + "</strong> degrees" );
 }
});
