}
}
view.on(["pointer-down", "pointer-move"], function (evt) {
// 向右移五个像素，以防无法取消菜单
changePosition(evt.x + 5, evt.y);
});
view.on("pointer-down", function (event) {
view.hitTest(event).then(function (response) {
if (response.results[0]) {
var graphic = response.results[0].graphic;
// 可通过graphic 的属性判断点击的类型
// 右键
if (event.button === 2) {
toggleMenu();
}
// 鼠标左键
else if (event.button === 0) {
}
}
});
});
});
