First of all you need to set the property correctly
首先,您需要正确设置属性
$('#test').animate({ 'background-color': 'rgba(0, 0, 0, 0.7)' },1000);
then you need to include jquery-ui to animate colours.
那么你需要包含jquery-ui来动画颜色。

You can also use css transitions to animate background colours
您还可以使用css过渡来为背景颜色设置动画
#test {
background-color: rgba(0, 0, 0, 0);
-webkit-transition:background-color 1s;
-moz-transition:background-color 1s;
transition:background-color 1s;
}

When using animate function don't use background-color but backgroundColor instead. So here is the working code :
使用动画功能时,请不要使用background-color而应使用backgroundColor。所以这是工作代码:
$('#test').animate({ backgroundColor: "rgba(0,0,0,0.7)" });
