Ich habe einige Probleme mit einer Schulaufgabe. Sowieso, wenn ich startInterval verwende, weise ich und intervalID zu, also kann ich später das Intervall löschen. Leider löscht es nicht, wenn Sie den "Stop this Madness" Knopf drücken. Wer weiß warum?clearInterval Ausgabe (jquery, javascript)
(wenn Sie sich fragen, über all die Hintergrundfarbe Sachen habe ich ein jQuery-Plugin, das ich nicht auf diese Schnipsel nicht hinzugefügt)
var intervalID;
$('.gal').click(function() {
var photoID = jQuery(this).attr("id");
alert(alerts[photoID]);
});
var alerts = {
//row one
"1:1": "This animal is a penguin!",
"1:2": "This animal is a lion!",
"1:3": "This animal is a cat!",
"1:4": "This animal is a giraffe!",
//row two
"2:1": "Cool looking ancient building!",
"2:2": "Cool looking modern building!",
"2:3": "Cool building from dubai!",
"2:4": "Cool building by the water!"
};
$("#stop").click(function() {
clearInterval(intervalID);
});
$(window).load(function() {
animate();
});
function animate() {
intervalID = setInterval(function() {
var width = 25;
$(".gal").animate({
'marginLeft': '-=25px'
});
$(".gal").animate({
'marginLeft': '+=25px'
});
$("#title").animate({
'marginLeft': '+=' + width + 'px'
