Las barras de progreso son elementos de las interfaces gr\u00e1ficas\u00a0 que permiten mostrar de forma gr\u00e1fica el estado de avance de una tarea o proceso. Generalmente el gr\u00e1fico est\u00e1 acompa\u00f1ado de informaci\u00f3n en forma de texto para medir con exactitud el avance. Por ejemplo, con estas barras puede verse el progreso en la descarga o transferencia de un archivo, el porcentaje de renderizado de un modelo 3D, el avance en la carga de un juego, etc.<\/p>\n

En este art\u00edculo vamos a ver como crear una barra de progreso utilizando un plugin jQuery como la que mostramos en la siguiente imagen:<\/p>\n

\"progress-bar-animation\"<\/p>\n

En la cabecera de nuestra p\u00e1gina tendremos que a\u00f1adir la librer\u00eda jQuery, el plugin jQuery progress y la llamada al plugin, por ejemplo de la siguiente forma:<\/p>\n

<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
<script src="\/\/ajax.googleapis.com\/ajax\/libs\/jquery\/1.10.2\/jquery.min.js"><\/script>\n<script src="js\/progress.js" type="text\/javascript" charset="utf-8"><\/script>\n<<\/span>script type=<\/span>"text\/javascript"<\/span>><\/span>\n$(<\/span>document)<\/span>.ready<\/span>(<\/span>function<\/span>(<\/span>)<\/span>{<\/span>\n    \/\/ Hide the label at start<\/span>\n    $(<\/span>'#progress_bar .ui-progress .ui-label'<\/span>)<\/span>.hide<\/span>(<\/span>)<\/span>;<\/span>\n    \/\/ Set initial value<\/span>\n    $(<\/span>'#progress_bar .ui-progress'<\/span>)<\/span>.css<\/span>(<\/span>'width'<\/span>,<\/span> '7%'<\/span>)<\/span>;<\/span>\n \n    \/\/ Simulate some progress<\/span>\n    $(<\/span>'#progress_bar .ui-progress'<\/span>)<\/span>.animateProgress<\/span>(<\/span>43,<\/span> function<\/span>(<\/span>)<\/span> {<\/span>\n        $(<\/span>this<\/span>)<\/span>.animateProgress<\/span>(<\/span>79,<\/span> function<\/span>(<\/span>)<\/span> {<\/span>\n            setTimeout(<\/span>function<\/span>(<\/span>)<\/span> {<\/span>\n                $(<\/span>'#progress_bar .ui-progress'<\/span>)<\/span>.animateProgress<\/span>(<\/span>100,<\/span> function<\/span>(<\/span>)<\/span> {<\/span>\n                  $(<\/span>'.content_success'<\/span>)<\/span>.slideDown<\/span>(<\/span>)<\/span>;<\/span>\n                }<\/span>)<\/span>;<\/span>\n            }<\/span>,<\/span> 3000)<\/span>;<\/span>\n        }<\/span>)<\/span>;<\/span>\n    }<\/span>)<\/span>;<\/span>\n}<\/span>)<\/span>;<\/span>\n<\/<\/span>script><\/span><\/pre><\/div><\/div>\n
 <\/p>\n
En este caso, estamos indicando que queremos una barra de progreso con animaci\u00f3n de duraci\u00f3n de 3 segundos. Al finalizar este tiempo se acaba la animaci\u00f3n y mostramos con efecto slideDown un contenedor escondido.<\/p>\n
Necesitaremos a\u00f1adir tambi\u00e9n en nuestra hoja de estilos:<\/p>\n
.ui-progress-bar {\r\n  position: relative;\r\n  height: 35px;\r\n  padding-right: 2px;\r\n  background-color: #DADADA;\r\n  border-radius: 5px;\r\n  -moz-border-radius: 5px;\r\n  -webkit-border-radius: 5px;\r\n}\r\n\r\n.ui-progress {\r\n  position: relative;\r\n  display: block;\r\n  overflow: hidden;\r\n  height: 33px;\r\n  -moz-border-radius: 5px;\r\n  -webkit-border-radius: 5px;\r\n  border-radius: 5px;\r\n  -webkit-background-size: 44px 44px;\r\n  background-color: #74d04c;\r\n  border: 1px solid #4c8932;\r\n  -webkit-animation: animate-stripes 2s linear infinite;\r\n}\r\n\r\n.ui-progress span.ui-label {\r\n  font-size: 1.2em;\r\n  position: absolute;\r\n  right: 0;\r\n  line-height: 33px;\r\n  padding-right: 12px;\r\n  color: rgba(0,0,0,0.6);\r\n  text-shadow: rgba(255,255,255, 0.45) 0 1px 0px;\r\n  white-space: nowrap;\r\n}<\/pre>\n
Y ahora tan solo queda a\u00f1adir los tags HTML dentro del <body>:<\/p>\n
<\/a>Source code<\/a><\/td><\/a> <\/a> <\/a> <\/td><\/tr><\/table><\/div>
