我如何修改以下代码，使绘制的线为虚线，您可以在提供的 jfiddle 中看到它的实际效果。
<html>
<style>
#canvas
{
border-style:solid;
border-width:1px;
}
</style>
<div id="canvas">
<p>Hover over me</p>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</html>
$(function() {
animateLine = function(canvas, hoverDivName, colorNumber, pathString) {
$('#' + hoverDivName).hover(
function() {
var line = canvas.path(pathString).attr({
stroke: colorNumber
});
var length = line.getTotalLength();
$('path[fill*="none"]').animate({
'to': 1
}, {
duration: 5000,
step: function(pos, fx) {
var offset = length * fx.pos;
var subpath = line.getSubpath(0, offset);
canvas.clear();
canvas.path(subpath).attr({
stroke: colorNumber
});
},
});
}, function() {
$('path[fill*="none"]').stop(true, false).fadeOut();
});
};
var canvas = Raphael('canvas', 200, 200);
var pathString = "M10 10L10 200L100 200Z";
animateLine(canvas, "canvas", "#000", pathString);
});
最佳答案
使用“stroke-dasharray”属性:
https://developer.mozilla.org/en-US/docs/SVG/Attribute/stroke-dasharray
例如:
canvas.path(subpath).attr({
stroke: colorNumber,
"stroke-dasharray":"--"
});
