FusionCharts-我尝试创建一个column2d图表。我有一个要求,我需要点击图表的其中一个栏并刷新下表中的一些数据。除此之外,我需要更改我点击的栏的颜色。我能够使用link属性设置为javascript函数并刷新该函数中的表来完成第一个。但第二个要求(改变颜色)我无法完成。我尝试使用DOM获取HTML元素并更改颜色。但是,我无法获取元素,但Raphael创建的固有对象(fusionchart使用raphael)。我也尝试使用对象的raphaelID属性访问元素,但这没用。我希望这可以在客户端完成,无需任何刷新。我还尝试使用事件来点击作为FisionChart的数据源的一部分。

barChart.render(chartToRenderId);
下面是我使用HTML属性访问元素的代码。
try {
var day = parseInt(selectedDate.substring(0, 2));
var rectangleBars = $(".red-hot-2").find("rect");
var rectangle = rectangleBars[day - 1];
var element = document.getElementById(rectangle.raphaelid);
element.click(function () {
this.attr('background-color', 'white');
});
}
catch (e) { }
答案 0 :(得分:1)
background-color不是属性,试试这个:
try {
var day = parseInt(selectedDate.substring(0, 2));
var rectangleBars = $(".red-hot-2").find("rect");
var rectangle = rectangleBars[day - 1];
var element = document.getElementById(rectangle.raphaelid);
element.click(function () {
$(this).css("background-color", "white");
});
}
catch (e) { }
