[英]how i can assign ids to svg elements? (to raphaeljs bars)
我如何在g.raphael条形图中为raphaeljs条指定id,以及如何在之后访问它们
var r = Raphael("holder", 600, 500);
var data=[1,3,4,5];
var chart = r.g.barchart(30, 30, 350, 250, [data], {stacked: true, type: "soft"});
for (var i = 0; i < chart.bars[0].length; i++) {
var bar = chart.bars[0][i];
if (bar.value >= 7) {
bar.attr("fill", "#bf2f2f");
bar.attr("stroke", "#bf2f2f");
bar.attr("id","id-"+i); //this doesn't work
bar.id="id-"+i; //this also doesn't work
//applied as per raphaeljs documentatoion
//[http://raphaeljs.com/reference.html#Element.id][1]
}
}
