我将 Raphael 与 Meteor 一起使用,但遇到了问题。我正在paper
使用创建一个var paper = Raphael("paper", 800, 600);
如果我把这段代码放在一个渲染函数中,比如 Template.board.rendered,我可以很好地使用它。但是,这个模板中的纸质变量显然不能被其他函数访问,即使我从模板中调用它们也是如此。我认为我可以通过在 中创建论文来解决这个Meteor.startup
问题,但我仍然遇到同样的问题。
例如,以下代码不起作用:
Pieces = new Meteor.Collection('pieces');
Meteor.startup(function () {
var paper = Raphael("paper", 800, 600);
});
Template.board.rendered = function () {
// If I create the paper in here along with the contents of createGoban
// it works, but then I can't use it anywhere else...
// var paper = Raphael("paper", 800, 600);
createGoban();
};
var createGoban = function () {
// Create goban

var rect_a = paper.rect(0, 0, 96, 96);
rect_a.attr({fill: '#DCB35C','stroke-width': '0','stroke-opacity': '1'}).data('id', 'rect_a');
var path_b = paper.path("M2.9,93h90.2m-.2-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m0-5h90m0-5H3m-.1-5h90.2M3,3V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3m5,0V93m5,0V3");
path_b.attr({stroke: '#000',"stroke-width": '0.2',fill: 'none','stroke-opacity': '1'}).data('id', 'path_b');
var path_c = paper.path("M18,78l0,0m30,0l0,0m30,0l0,0m0-30l0,0m-30,0l0,0m-30,0l0,0m0-30l0,0m30,0l0,0m30,0l0,0");
path_c.attr({stroke: '#000',"stroke-width": '4',"stroke-linecap": 'round','stroke-opacity': '1','fill': '#000000'}).data('id', 'path_c');
var goban = [rect_a, path_b, path_c];
// Scale goban up since rsr outputs reduced size
for(var i = 0; i < goban.length; i++) {
goban[i].transform('S5,5,0,0');
};
};
