Question

我需要添加动作onclick会改变颜色（灰色）。然后它将保持灰色，直到它被点击到另一个标签。

我想在选定状态下显示标签（通过灰色）。如果单击另一个选项卡，其颜色将变为灰色，之前单击选项卡颜色更改为白色。

这是我的代码的一部分： enter image description here

        <link rel="stylesheet" href="demo-print.css" type="text/css" media="print">
        <style type="text/css" media="screen">
            #canvas {
                height: 300px;
                left: 50%;
                margin: -150px 0 0 -300px;
                position: absolute;
                top: 50%;
                width: 600px;
            }
            #paper {
                height: 300px;
                left: 0;
                position: absolute;
                top: 0;
                width: 300px;
            }
            #nsw, #vic, #wa, #sa, #nt, #qld, #tas {
                display: none;

                width: 300px;
            }

以下是您的代码的简化版本，我删除了无关的部分以简化工作：

var R = Raphael("paper", 700, 700);
var aus = {};
aus.nsw = R.set()
aus.vic = R.set()
aus.wa = R.set()
aus.sa = R.set()
var boxattrs = {'cursor': 'pointer', 'fill' : "#fff"}
var attrs = {fill: '#000000', 'font-family':'Verdana', 'font-size':'14px', 'font-weight': 'bold', 'cursor': 'pointer'}
var outsideRectX1=30.5, outsideRectY1=30.5,outsideRectX2=220.5, outsideRectY2=480.5, outsideRectR=10.5;
var i = 0;

for (state in aus) {
  aus[state].push(R.rect((outsideRectX1+90)*i+80, outsideRectY1+70, 120, 40,0).attr(boxattrs));
  aus[state].push(R.text((outsideRectX1+90)*i+115, outsideRectY1+85,"tab" + (i+1)).attr(attrs));
  aus[state].click(highlight)
  i++;
}

function highlight() {
   for (state in aus) {
     if(aus[state][0].attr("fill") == "#CCCCCC") {
       aus[state][0].animate({fill: "#FFFFFF", "stroke": "#000"}, 300)
     }
   }
   node = (this.type == "rect") ? this : this.prev
   node.animate({fill: "#CCCCCC", "stroke": "#CCC"}, 300)
}

如何在rect上添加onclick操作以更改所选选项卡的颜色？
