如何创建一个带边框链接的圆圈 [英] How to create a circle with links on border side
问题描述
我想要创建一个像
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;}
< svg viewBox ='0 0 110 110'> < path d ='M55,55 L105,55 A50,50 0 0,1 98.30,80z'/> < path d ='M55,55 L98.30,80 A50,50 0 0,1 80,98.30z'/> < path d ='M55,55 L80,98.30 A50,50 0 0,1 55,105z'/> < path d ='M55,55 L55,105 A50,50 0 0,1 30,98.30z'/> < path d ='M55,55 L30,98.30 A50,50 0 0,1 11.69,80z'/> < path d ='M55,55 L11.69,80 A50,50 0 0,1 5,55z'/> < path d ='M55,55 L5,55 A50,50 0 0,1 11.69,30z'/> < path d ='M55,55 L11.69,30 A50,50 0 0,1 30,11.69z'/> < path d ='M55,55 L30,11.69 A50,50 0 0,1 55,5z'/> < path d ='M55,55 L55,5 A50,50 0 0,1 80,11.69z'/> < path d ='M55,55 L80,11.69 A50,50 0 0,1 98.30,30z'/> < path d ='M55,55 L98.30,30 A50,50 0 0,1 105,55z'/>< / svg>
包含未分段内部的圆形：
如果它看起来好像圆的一部分（具有较小的半径）在中心看起来未分段，并且如果内部部分不需要是透明的，只需添加
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;} circle {fill：yellowgreen; stroke：black;}
< svg viewBox ='0 0 110 110'> < path d ='M55,55 L105,55 A50,50 0 0,1 80,98.30z'/> < path d ='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z'/> < path d ='M55,55 L30,98.30 A50,50 0 0,1 5,55z'/> < path d ='M55,55 L5,55 A50,50 0 0,1 30,11.69z'/> < path d ='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z'/> < path d ='M55,55 L80,11.69 A50,50 0 0,1 105,55z'/> < circle cx = '55'cy = '55'r = '25'/>< / svg>
p>
每个区隔的不同背景：
如果每个段都应该有不同的背景，那么只需将 fill 属性添加到每个路径元素。
svg {height：220px; width：220px;} path {stroke：black;} circle {fill：yellowgreen; stroke：black;}
< svg viewBox ='0 0 110 110'> < path d ='M55,55 L105,55 A50,50 0 0,1 80,98.30z'fill ='crimson'/> < path d ='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z'fill ='tomato'/> < path d ='M55,55 L30,98.30 A50,50 0 0,1 5,55z'fill ='sandybrown'/> < path d ='M55,55 L5,55 A50,50 0 0,1 30,11.69z'fill ='mediumseagreen'/> < path d ='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z'fill ='chocolate'/> < path d ='M55,55 L80,11.69 A50,50 0 0,1 105,55z'fill ='teal'/> < circle cx = '55'cy = '55'r = '25'/>< / svg>

透明内部部分的演示：
如果中心部分不能具有纯色，则整个事物变得更复杂，因为我们不能再在中心点开始和结束路径。在这种情况下，我们必须在外圈和内圈上找到点，如下所示：
在这种情况下，路径必须从From（Inner）开始，并在同一点结束起始线应绘制为从（外），然后弧线To（外），线To（内）和弧线
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;}
< svg viewBox ='0 0 110 110'> < path d ='M80,55 L105,55 A50,50 0 0,1 80,98.30 L67.5,76.65 A25,25 0 0,0 80,55z'/> < path d ='M67.5,76.65 L80,98.30 A50,50 0 0,1 30,98.30 L42.5,76.65 A25,25 0 0,0 67.5,76.65z'/> <路径d ='M42.5,76.65 L30,98.30 A50,50 0 0,1 5,55 L30,55 A25,25 0 0,0 42.5,76.65z'/> < path d ='M30,55 L5,55 A50,50 0 0,1 30,11.69 L42.5,33.34 A25,25 0 0,0 30,55z'/> <路径d ='M42.5,33.34 L30,11.69 A50,50 0 0,1 80,11.69 L67.5,33.34 A25,25 0 0,0 42.5,33.34z'/> < path d ='M67.5,33.34 L80,11.69 A50,50 0,01 105,55 L80,55 A25,25 0 0,0 67.5,33.4z'/>< / svg>
细分可点击的链接：
一旦形状本身已创建，这很简单。像chipChocolate.py的答案，只是包装每个路径在一个SVG锚标签（< a xlink：href =＃> 其中
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;}
< svg viewBox ='0 0 110 110'> < a xlink：href =＃>< path d ='M55,55 L105,55 A50,50 0 0,1 80,98.30z'/>< / a> < a xlink：href =＃>< path d ='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z'/>< / a> < a xlink：href =＃>< path d ='M55,55 L30,98.30 A50,50 0 0,1 5,55z'/>< / a> < a xlink：href =＃>< path d ='M55,55 L5,55 A50,50 0 0,1 30,11.69z'/>< / a> < a xlink：href =＃>< path d ='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z'/>< / a> < a xlink：href =＃>< path d ='M55,55 L80,11.69 A50,50 0 0,1 105,55z'/>< / a>< / svg& code>
形状内的文本：
SVG中的文本添加稍微复杂一些，因为我们必须指定文本的放置点。如果文本相当小（例如几个字符），则我们可以再次在圆上找到点，使得角度恰好在段的中间并使用它。半径可以被设置为使得它是父圆半径的一半（如果没有未分段的部分）或者使得它在内圆和外圆之间的一半。通过CSS添加的 text-anchor ， dominant-baseline 设置将确保文本位于
如果文本很大（需要循环），那么额外的处理应该因为SVG text 标签内的内容不会自动换行。
圆的点计算6段，没有中心未分段区域：
具有6个片段和中心未分段区域的圆的点计算：
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;} text {text-anchor：middle;显性基线：中间; / *不能在IE * / font：12px中使用Calibri，Arial;}

使用JavaScript动态创建：
下面是一个粗略的基于JS的实现，以便动态创建段。该函数采用四个参数 - 圆的中心的X坐标，其中心的Y坐标，圆的半径和no。
var fromAngle，toAngle， fromCoordX，fromCoordY，toCoordX，toCoordY，path，d; function createPie（cx，cy，r，slices）{for（var i = 0; i
svg {height：220px; width：220px;} path {fill：transparent; stroke：black;}
< svg viewBox =0 0 110 110id =pie>< / svg>
JS示例不包含未分段内圈的示例，但可以通过扩展此示例来实现。
I am trying to make a circle like this. I was able to make it in the fiddle, but the problem is that I need each orange side to be a link and I can't do it with borders. If anyone can help me with this I will be really grateful.
#circle {
width: 200px;
height: 200px;
border-radius: 50%;
background: green;
}
#incircle {
width: 100px;
height: 100px;
border-radius: 50%;
border: 50px dotted orange;
}
<div id="circle">
<div id="incircle"></div>

The key to creating a circle with segments is to find points along the circle which would be used in the SVG path elements as coordinates. Finding points on a circle can be done easily using trigonometric equations if we know the angles.
X Coordinate of point = Radius of the circle * Cos(Angle in Radians) + X Coordinate of center point
Y Coordinate of point = Radius of the circle * Sin(Angle in Radians) + Y Coordinate of center point
Angle in Radians = Angle in Degrees * Math.PI / 180
The angles depend on the no. of segments that we have to create. The generic formula is (360 / no. of segments). So to create a circle with 6 segments, the angle covered by each of the segment would be 60 degrees. The first segment would cover from 0 to 60 degrees, second from 60 to 120 degrees and so on.
Demo of Circle with 6 Segments:
Below table shows how the points are calculated for a circle with 6 segments (where radius of circle is 50, center point is 55,55):
Once the points are calculated, coding the path itself is simple. The path should start and end at the center point (which is 50,50), from the center point, we should first draw a line to From Point and from there draw an arc to the To Point. Below is how a sample path would look like:
<path d='M55,55 L105,55 A50,50 0 0,1 80,98.30z' />
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<path d='M55,55 L105,55 A50,50 0 0,1 80,98.30z' />
<path d='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z' />
<path d='M55,55 L30,98.30 A50,50 0 0,1 5,55z' />
<path d='M55,55 L5,55 A50,50 0 0,1 30,11.69z' />
<path d='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z' />
<path d='M55,55 L80,11.69 A50,50 0 0,1 105,55z' />
</svg>
Demo of Circle with 12 Segments:
For a circle with 12 segments, each segment would cover 30 degrees and so the points would be calculated as in the below table:
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<path d='M55,55 L105,55 A50,50 0 0,1 98.30,80z' />
<path d='M55,55 L98.30,80 A50,50 0 0,1 80,98.30z' />
<path d='M55,55 L80,98.30 A50,50 0 0,1 55,105z' />
<path d='M55,55 L55,105 A50,50 0 0,1 30,98.30z' />
<path d='M55,55 L30,98.30 A50,50 0 0,1 11.69,80z' />
<path d='M55,55 L11.69,80 A50,50 0 0,1 5,55z' />
<path d='M55,55 L5,55 A50,50 0 0,1 11.69,30z' />
<path d='M55,55 L11.69,30 A50,50 0 0,1 30,11.69z' />
<path d='M55,55 L30,11.69 A50,50 0 0,1 55,5z' />
<path d='M55,55 L55,5 A50,50 0 0,1 80,11.69z' />
<path d='M55,55 L80,11.69 A50,50 0 0,1 98.30,30z' />
<path d='M55,55 L98.30,30 A50,50 0 0,1 105,55z' />
</svg>
Circle with an unsegmented inner portion:
If it should look as though a portion of the circle (with a smaller radius) in center looks unsegmented and if that inner portion need not be transparent, just add an extra circle element at the end within the SVG.
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
circle {
fill: yellowgreen;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<path d='M55,55 L105,55 A50,50 0 0,1 80,98.30z' />
<path d='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z' />
<path d='M55,55 L30,98.30 A50,50 0 0,1 5,55z' />
<path d='M55,55 L5,55 A50,50 0 0,1 30,11.69z' />
<path d='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z' />
<path d='M55,55 L80,11.69 A50,50 0 0,1 105,55z' />
<circle cx='55' cy='55' r='25' />
</svg>
Different Background for each Segment:
If each of the segments should have a different background to them then just add the fill attribute to each path element.
svg {
height: 220px;
width: 220px;
}
path {
stroke: black;
}
circle {
fill: yellowgreen;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<path d='M55,55 L105,55 A50,50 0 0,1 80,98.30z' fill='crimson' />
<path d='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z' fill='tomato' />
<path d='M55,55 L30,98.30 A50,50 0 0,1 5,55z' fill='sandybrown' />
<path d='M55,55 L5,55 A50,50 0 0,1 30,11.69z' fill='mediumseagreen' />
<path d='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z' fill='chocolate' />
<path d='M55,55 L80,11.69 A50,50 0 0,1 105,55z' fill='teal' />
<circle cx='55' cy='55' r='25' />
</svg>
Demo with a transparent inner portion:
If the center portion cannot have a solid color then the whole thing becomes more complex because we can no longer start and end the path at the center point. In such cases, we have to find points on both the outer circle and the inner circle like below:
In this case, the path has to start from the "From(Inner)" and end at same point, from the start a line should be drawn to "From(Outer)", then an arc to "To(Outer)", a line to "To(Inner)" and an arc to "From (Inner)".
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<path d='M80,55 L105,55 A50,50 0 0,1 80,98.30 L67.5,76.65 A25,25 0 0,0 80,55z' />
<path d='M67.5,76.65 L80,98.30 A50,50 0 0,1 30,98.30 L42.5,76.65 A25,25 0 0,0 67.5,76.65z' />
<path d='M42.5,76.65 L30,98.30 A50,50 0 0,1 5,55 L30,55 A25,25 0 0,0 42.5,76.65z' />
<path d='M30,55 L5,55 A50,50 0 0,1 30,11.69 L42.5,33.34 A25,25 0 0,0 30,55z' />
<path d='M42.5,33.34 L30,11.69 A50,50 0 0,1 80,11.69 L67.5,33.34 A25,25 0 0,0 42.5,33.34z' />

</svg>
Making each segment a clickable link:
This is pretty simple to do once the shape itself has been created. Like in chipChocolate.py's answer, just wrap each path within a SVG anchor tag (<a xlink:href="#"> where # should be replaced the URL of the linked page).
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
<svg viewBox='0 0 110 110'>
<a xlink:href="#"><path d='M55,55 L105,55 A50,50 0 0,1 80,98.30z' /></a>
<a xlink:href="#"><path d='M55,55 L80,98.30 A50,50 0 0,1 30,98.30z' /></a>
<a xlink:href="#"><path d='M55,55 L30,98.30 A50,50 0 0,1 5,55z' /></a>
<a xlink:href="#"><path d='M55,55 L5,55 A50,50 0 0,1 30,11.69z' /></a>
<a xlink:href="#"><path d='M55,55 L30,11.69 A50,50 0 0,1 80,11.69z' /></a>
<a xlink:href="#"><path d='M55,55 L80,11.69 A50,50 0 0,1 105,55z' /></a>
</svg>
Adding text within the shape:
Text addition in SVG is slightly more complex because again we have to specify the point where the text should be placed. If the text is reasonably small (say a few characters), then we can again find points on the circle such that the angle is exactly in the middle of the segment and use it. The radius could be set such that it is half the parent circle's radius (if there is no unsegmented portion) or such that it is half way between the inner circle and outer circle. The text-anchor, dominant-baseline settings that are added via CSS would make sure that the text is positioned in such a way that both the horizontal and vertical center of the text matches with the specified point.
If the text is large (and needs to wrap around), then extra handling should be done because contents within the SVG text tag won't get wrapped around automatically.

Below is a rough JS based implementation in order to create the segments dynamically. The function takes four arguments - the X coordinate of the circle's center, the Y coordinate of its center, the radius of the circle and the no. of segments/slices.
var fromAngle, toAngle, fromCoordX, fromCoordY, toCoordX, toCoordY, path, d;
function createPie(cx, cy, r, slices) {
for (var i = 0; i < slices; i++) {
path = document.createElementNS("http://www.w3.org/2000/svg", "path");
fromAngle = i * 360 / slices;
toAngle = (i + 1) * 360 / slices;
fromCoordX = cx + (r * Math.cos(fromAngle * Math.PI / 180));
fromCoordY = cy + (r * Math.sin(fromAngle * Math.PI / 180));
toCoordX = cx + (r * Math.cos(toAngle * Math.PI / 180));
toCoordY = cy + (r * Math.sin(toAngle * Math.PI / 180));
d = 'M' + cx + ',' + cy + ' L' + fromCoordX + ',' + fromCoordY + ' A' + r + ',' + r + ' 0 0,1 ' + toCoordX + ',' + toCoordY + 'z';
path.setAttributeNS(null, "d", d);
document.getElementById('pie').appendChild(path);
}
}
createPie(55, 55, 50, 6);
svg {
height: 220px;
width: 220px;
}
path {
fill: transparent;
stroke: black;
}
<svg viewBox="0 0 110 110" id="pie"></svg>
JS sample doesn't cover the examples with an unsegmented inner circle but that can be achieved by extending this.
