Question

我刚刚发现拉斐尔，并且喜欢它，但我不是一个javascript-er。现在我有三个重复的代码段在三个不同的div中绘制相同的圆圈。在Raphael中制作画布的默认设置通过ID找到一个元素，但是我希望有一组变量可以在所有div中使用“circle”类绘制圆圈。我认为必须有一种更有效的编码方式。这是我现在使用的代码：

window.onload = function () {
    var paper = Raphael("c1", 26, 26); /* Make canvas 26*26px in div id "c1" */
    var circle = paper.circle(13, 13, 10.5); /* Draw circle at the center of the canvas with radius 10.5  */
    circle.attr("stroke", "#f1f1f1");
    circle.attr("stroke-width", 2);
    var text = paper.text(13, 13, "1"); /* Print text "1" inside the circle  */
    text.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'});
    text.attr("fill", "#f1f1f1");

    var paper2 = Raphael("c2", 26, 26);
    var circle2 = paper2.circle(13, 13, 10.5);
    circle2.attr("stroke", "#f1f1f1");
    circle2.attr("stroke-width", 2);
    var text2 = paper2.text(12, 13, "2");
    text2.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'});
    text2.attr("fill", "#f1f1f1");

    var paper3 = Raphael("c3", 26, 26);
    var circle3 = paper3.circle(13, 13, 10.5);
    circle3.attr("stroke", "#f1f1f1");
    circle3.attr("stroke-width", 2);
    var text3 = paper3.text(12, 13, "3");
    text3.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'});
    text3.attr("fill", "#f1f1f1");
};

定义一个函数，该函数接受div的参数，以便您可以自动化该过程：

function drawcircle(div, text) { 
    var paper3 = Raphael(div, 26, 26); //<<
    var circle3 = paper3.circle(13, 13, 10.5);
    circle3.attr("stroke", "#f1f1f1");
    circle3.attr("stroke-width", 2);
    var text3 = paper3.text(12, 13, text); //<<
    text3.attr({'font-size': 15, 'font-family': 'FranklinGothicFSCondensed-1, FranklinGothicFSCondensed-2'});
    text3.attr("fill", "#f1f1f1");
}

然后在你的window.onload：

window.onload = function () {
    drawcircle("c1", "1");
    drawcircle("c2", "2");
    drawcircle("c3", "3");
};

Raphael js使用指定的类在所有元素中绘制圆圈
