我有以下代码,我在队列中的两个循环中添加效果:
tablaActual = ({
1111: {
titulo: "Nuevo Video 1",
usuario: "RadioBot",
alta: "1353182478"
},
2243: {
titulo: "Old Boy Fashion",
usuario: "RadioBot",
alta: "1353182479"
},
3432: {
titulo: "Britney spears",
usuario: "RadioBot",
alta: "1353182825"
}
});
tablaNueva = ({
1111: {
titulo: "Nuevo Video 1",
usuario: "RadioBot",
alta: "1353182478"
},
1112: {
titulo: "Nuevo video 2",
usuario: "RadioBot",
alta: "1353182477"
},
1113: {
titulo: "Nuevo video 3",
usuario: "RadioBot",
alta: "1353182476"
}
});
$("button").bind("click", function() {
var body = $('body');
retardation = 500;
i = 1;
// we delete the old ones that doesnt match in the new table
$.each(tablaActual, function(index) {
if (!tablaNueva[index]) {
delay = i * retardation;
$('#lista #id' + index).delay(delay).slideUp("normal", function() {
$(this).remove();
}).queue("cola1");
delete tablaActual[index];
i++;
}
});
// we add the new ones that doesnt match in the old table
$.each(tablaNueva, function(index, vars) {
if (!tablaActual[index]) {
delay = i * retardation;
$('<tr id="id' + index + '"><td class="cancion"><h3>' + vars.titulo + '</h3></td><td class="autor">' + vars.usuario + '<span>' + vars.alta + '</span></td></tr>').appendTo('#lista').hide().delay(delay).show('slow').queue("cola2");
tablaActual[index] = vars;
i++;
}
});
$("tr:animated").promise().done(function() {
alert("done");
});
});
当所有的TR动画完成时,它应该触发警报,但我认为我做错了,因为一旦我点击运行按钮就会弹出警报.
我该怎么做呢?
最佳答案 我使用jQuery.Deferred()来使它工作.通过这样做,您可以排队一些延迟对象,这些对象在相应的项目动画完成后解析.
简而言之,创建一个延迟对象数组并使用有点奇怪的构造jQuery.when.apply(…).done(function(){…})等待它们.
