问题描述

我使用jQuery中的步骤为CSS转换属性设置了动画.我为动画功能保留的时间限制都没有考虑到.我的代码是这样的

Am using step in jQuery animate to animate CSS transform property.What ever the time limit that i kept for animate function its not taking into consideration.My code is like this

$('#instructions').animate({now:'+=50'},{
    step: function(now) {
      $(this).css('transform','rotate('+now+'deg)'), duration:'slow'
    }
},50000);

在这里，我将div旋转约50度，时间跨度为50000ms，但不会花费那50000ms.我可以做什么来创建那个时间跨度.预先感谢.

Here am rotating my div about 50 deg with a time span of 50000ms,but its not taking those 50000ms.What i can do to create that time span.Thanks in advance.

这是我的HTML.

Am使div像钟摆一样旋转.

Am making the div rotation like a pendulum clock.

推荐答案

您使用的.animate参数不正确-您正在尝试传递duration 和 options不存在.您可以使用以下任一方式拨打电话:

You are using .animate with the incorrect parameters - you are trying to pass a duration and options which doesn't exist. You call using either:

.animate( properties [, duration ] [, easing ] [, complete ] )
.animate( properties, options )

.animate( properties [, duration ] [, easing ] [, complete ] )
.animate( properties, options )

如果使用第二个版本，则需要在options对象中设置duration属性.

If you use the second version, then you need to set the duration property inside the options object.

这有效:

$(document).ready(function(){
    var animDuration = 1000;

    $('#instructions').animate({  now: '+=50' }, {
        duration:animDuration,
        step: function(now,fx) {
            $(this).css('transform','rotate('+now+'deg)');
        }
    });

    $('#instructions').animate({  now: '-=100' }, {
        duration:animDuration,
        step: function(now,fx) {
          $(this).css('transform','rotate('+now+'deg)');  
        }
    });

    $('#instructions').animate({  now: '+=50' }, {
        duration:animDuration,
        step: function(now,fx) {
          $(this).css('transform','rotate('+now+'deg)');  
        }
    });

})
