我正在尝试使搜索栏动画化。我能够使它在您单击时绘制,并在您再次单击时返回到原始位置(使用greensock-drawSVG)。

我希望能够在不刷新页面的情况下再次单击,并使一切正常运行。到目前为止,只有drawSVG是唯一不能恢复活动的东西。

我也不确定为什么drawSVG属性在这里不起作用,它在我自己的计算机上确实起作用。 (I am attaching a gif of the animation from my computer

最佳答案

DrawSVGPlugin.js插件未加载。没有此插件,DrawSVG功能将无法使用。

使用https加载的页面不会使用http加载javascript。这被称为"mixed content",并且出于安全原因被浏览器阻止。



至于动画,我认为这是因为您尝试使用.from()而不正确初始化元素的状态。

drawSVG一样,不要使用整数作为"100%"属性,而应使用百分比。当您使用整数时,这些整数将被解释为原始长度,这可能需要一些时间才能弄清楚。使用百分比时,DrawSVG会为您解决。

无需弄乱先前的状态,而是根据需要为"0%""100%"设置动画。

所以用

TweenMax.set([$drawSearch], {drawSVG:"0%"});


然后使用

TweenMax.to($drawSearch, 1, {drawSVG:"0%", delay:0.5});




TweenMax.to($drawSearch, 0.75, {drawSVG:"100%", delay:0.50});
