如何顺时针旋转圆

Question

我正在使用HTML5和CSS3。当我们点击它的时候，我想顺时针旋转所有的圆。对于旋转的圆圈，我只使用CSS。我已经为同样的添加了html和css，所有的圆圈都是按他们的点击旋转的，点击的圆圈会被高亮，并显示为白色的圆圈。

Answer 1

下面是一个例子：http://jsfiddle.net/sxfzymst/

不好意思，数学不好，所以所有可能的旋转都会改变逻辑开关。

html (添加onclick)：

<input type="radio" id="info-compass" name="radio-check" onclick='rotateTo(0)' checked  />
<input type="radio" id="info-heart" name="radio-check" onclick='rotateTo(1)' />
<input type="radio" id="info-rss" name="radio-check" onclick='rotateTo(4)' />
<input type="radio" id="info-refresh" name="radio-check" onclick='rotateTo(3)' />
<input type="radio" id="info-star" name="radio-check" onclick='rotateTo(2)' />

css (删除跨浏览器转换属性)：

#info-star:checked ~ #menu-items, #menu-items .bottom .ss-rss { 
     -webkit-transition: -webkit-transform 1s ease-in;
     transition: 1s ease-in;
}

联署材料：

var currentRotatePosition = 0;
var currentDegree = 0;

function rotateTo(newPosition)
{
    var shift = 0;
    switch(currentRotatePosition)    
    {
        case 0:
            switch(newPosition)
            {
                // other cases
            }
    }
}

$('#menu-items, #menu-items .bottom .ss-refresh').css({
    '-webkit-transform': 'rotateZ('+ currentDegree +'deg)',
    '-moz-transform': 'rotateZ('+ currentDegree +'deg)',
    '-ms-transform': 'rotateZ('+ currentDegree +'deg)',
    '-o-transform': 'rotateZ('+ currentDegree +'deg)',
    'transform': 'rotateZ('+ currentDegree +'deg)',
});

Answer 2

将rotateZ()中的所有负数替换为正数。然后第一个点击将顺时针旋转，因为正值顺时针旋转，负值逆时针旋转。

通过增加360°，可以将负数转换为正度，例如-77°：

-77° + 360° = 283°

因此，您将得到以下代码，例如：

#info-heart:checked ~ #menu-items, #menu-items .top .ss-home { 
    -webkit-transform: rotateZ(283deg); 
    -moz-transform: rotateZ(283deg); 
    -ms-transform: rotateZ(283deg); 
    -o-transform: rotateZ(283deg); 
    transform: rotateZ(283deg); 
     -webkit-transition: -webkit-transform 1s ease-in;
     transition: 1s ease-in;
}

第二单击的旋转取决于第一和第二选择项的度值。如果第二度高于第一度，则旋转为顺时针方向。否则它会转到另一个方向。对于最后一种情况，我在CSS中看不到顺时针旋转的解决方案。
