我正在尝试制作一款 Angular 色扮演游戏，我也按照我想要的方式生成了 Angular 色，但是在 $(".defend_button").on("click", function() 最后它没有'不按应有的方式更新数据健康状况。它只更新一次，但在多次点击防御按钮后，它不会更新超过第一次。

最佳答案
你必须使用 .data()更新健康值。
var battleResult = $(".defender").data("health") - $(".hero_button").data("attack");
console.log("battleResult should be: "+battleResult );
$(".defender").data({
"health": battleResult
});
我玩了一点你的游戏。
我也找到了如何更新图像下方的健康显示...
因为仅更新数据不会改变屏幕上的任何内容。
所以，我把上面的代码留在那里，让你看到它有效地工作。
但是因为你必须重新创建按钮来更新屏幕上的健康状况......这有点没用。
我也修复了死亡条件
来自 if($(".defender").data("health") == 0){
至 if($(".defender").data("health") <= 0){
在改变很多事情之前我必须在这里停下来。
在 CodePen 中查看
检查 it_is_over_9000() 中的循环，因为我认为它经常无用地运行。
死去的防守者必须被“埋葬”(笑)。
因为当它被杀死时，点击防御按钮可以使它复活。
