right-click on a d3.js element: how to prevent browser context menu to appear
提问by Askar Ibragimov
I have some d3.js element plotted, eg:
我绘制了一些 d3.js 元素，例如：
// draw rectangle
svg.selectAll(".rect").append("rect")
.attr("y", 10)
.attr("x", 10)
.attr("height", 5)
.attr("width", 5)
.on("contextmenu", function (d, i) {
// react on right-clicking
});
and it works fine but also opens browser's context menu. How I can prevent that from happening?
它工作正常，但也会打开浏览器的上下文菜单。我怎样才能防止这种情况发生？

Add d3.event.preventDefault();to your function.
添加d3.event.preventDefault();到您的功能中。
// draw rectangle
svg.selectAll(".rect").append("rect")
.attr("y", 10)
.attr("x", 10)
.attr("height", 5)
.attr("width", 5)
.on("contextmenu", function (d, i) {
d3.event.preventDefault();
// react on right-clicking
});
