Javascript 是否可以使用函数将document.getElementByID().innerHTML推送到HTML文件中?
我回来向社区提出另一个问题。我知道有很多关于document.getElementByID()的问题和答案,但是我找不到任何指向我正在寻找的路径的东西,而且它可能根本不存在 在我的基于文本的javascript游戏中,我有很多span,我希望缩短代码长度,因为对于每个声明和更改对象内部变量的实例,为了将其推送到HTML页面,我必须垃圾邮件使用document.getElementByID() 例如,在我的HTML文件中,我有:Javascript 是否可以使用函数将document.getElementByID().innerHTML推送到HTML文件中?,javascript,object,innerhtml,getelementbyid,Javascript,Object,Innerhtml,Getelementbyid,我回来向社区提出另一个问题。我知道有很多关于document.getElementByID()的问题和答案,但是我找不到任何指向我正在寻找的路径的东西,而且它可能根本不存在 在我的基于文本的javascript游戏中,我有很多span,我希望缩短代码长度,因为对于每个声明和更改对象内部变量的实例,为了将其推送到HTML页面,我必须垃圾邮件使用document.getElementByID() 例如,在我的HTML文件中,我有: <div id="attributes">

定义了一些常量:
const Male = {
Type: "Male",
Health: 100,
Mana: 20,
Strength: 20,
Defense: 5,
Endurance: 15,
Intelligence: 5,
Sexiness: 1,
Friend: "Duncan",
}
const Female = {
Type: "Female",
Health: 80,
Mana: 60,
Strength: 16,
Defense: 4,
Endurance: 12,
Intelligence: 10,
Sexiness: 2,
Friend: "Morgana",
}
以及性别分配功能:
function genderAssign() {
switch (Player.Gender) {
case "Male":
Player.Gender = Male.Type;
Player.Health = Male.Health;
Player.Mana = Male.Mana;
Player.Strength = Male.Strength;
Player.Defense = Male.Defense;
Player.Endurance = Male.Endurance;
Player.Intelligence = Male.Intelligence;
Player.Sexiness = Male.Sexiness;
Player.Friend = Male.Friend;
Armor.UpperClothesName = "Chest";
Armor.LowerClothesName = "Fig Leaves";
Armor.HelmetName = "Head";
Armor.BodyName = "Body";
Armor.ArmName = "Arms";
Armor.WaistName = "None";
Armor.LegName = "Legs";
Armor.BootsName = "Feet";
Weapons.RightHand = "Right Hand";
Weapons.LeftHand = "Left Hand";
Armor.LegCoveringsName = "Hair";
break;
case "Female":
Player.Gender = Female.Type;
Player.Health = Female.Health;
Player.Mana = Female.Mana;
Player.Strength = Female.Strength;
Player.Defense = Female.Defense;
Player.Endurance = Female.Endurance;
Player.Intelligence = Female.Intelligence;
Player.Sexiness = Female.Sexiness;
Armor.UpperClothesName = "Nip Coverings";
Armor.LowerClothesName = "Fig Leaves";
Armor.HelmetName = "Head";
Armor.BodyName = "Body";
Armor.ArmName = "Arms";
Armor.WaistName = "None";
Armor.LegName = "Legs";
Armor.BootsName = "Feet";
Weapons.RightHand = "Right Hand";
Weapons.LeftHand = "Left Hand";
Armor.LegCoveringsName = "Smooth Legs";
Player.Friend = Female.Friend;
break;
default:
}
return;
}
我不想做以下事情:
Player.Gender = Male.Type;
document.getElementByID("Male.Type").innerHTML = Male.Type
Player.Health = Male.Health;
document.getElementByID("Male.Health").innerHTML = Male.Health
Player.Mana = Male.Mana;
document.getElementByID("Male.Mana").innerHTML = Male.Mana
等等。。。
有没有一种方法可以做到:
function printPlayer() {
Player.Gender = $('#Player.Gender');
Player.Sexiness = $('#Player.Sexiness');
Player.Health = $('#Player.Health');
Player.Mana = $('#Player.Mana');
Player.Strength = $('#Player.Strength');
Player.Defense = $('#Player.Defense');
Player.Endurance = $('#Player.Endurance');
Player.Intelligence = $('#Player.Intelligence');
Player.Friend = $('#Player.Friend');
Player.Gold = $('#Player.Gold');
Player.Experience = $('#Player.Experience');
Player.Level = $('#Player.Level');
Player.ClassType = $('#Player.ClassType');
}
或
然后从内部调用它,比如genderasign()函数
抱歉,如果这有点长,但我宁愿给你一个更广泛的范围,我在做什么,而不是让它猜测。我尝试过上述功能,但两种功能都不起作用。错误是:

不确定这是否会改变我问题的答案,或者是否使用按钮是唯一的方法。此代码片段将为您提供一些处理播放器对象属性的方法,包括在页面上显示它们。
(有关脚本特定功能的说明,请参见代码内注释。)
//标识演示的按钮
const myButton=document.getElementById(“我的按钮”);
//单击按钮时调用“printInfoToPage”方法
myButton.addEventListener(“单击”,打印信息页面);
//定义播放器对象
康斯特玩家={
性感:5,
卫生:5,
法力:3,
人数:4人,,
答辩:3,
保龄球核心:5分
};
//(箭头函数)在其字符串参数前面加上“Player.”
常量mapPropNameToElementId=(propName)=>“玩家”。+propName;
//获取两个字符串,如果可能,更新匹配元素的textContent
函数setElementTextById(id,文本){
元素=document.getElementById(id);
if(element){//在继续之前确保元素存在
element.textContent=text;/`.innerHTML`也可以
}
};
函数printInfoToPage(){
//'Object'上的静态'.keys'方法获取对象的属性名
const playerPropNames=Object.keys(播放器);
//`for…of`通过数组循环
对于(让玩家角色名的道具){
//获取ID
常量elementId=mapPropNameToElementId(prop);
//获得价值
常量存储值=玩家[道具];
//更新页面上的元素
setElementTextById(elementId,storedValue);
}
}

显示玩家信息(Show Player Info)这个答案确实有效,但不是我想要的100%。。。这是我的错没有把所有需要的信息放在前面。我确实需要事件监听器,但我需要它在key.which==13(基本上是on.mouseUp或类似的东西)上,这样它就可以通过主代码页上的if语句。我想这会完全回答我的问题。我还在研究如何将此按钮改为mouseUp属性。。。似乎
event.key==“Enter”
是更现代的测试方法,但我希望您可以使用“event.which==13”
就可以了。试试看!英雄联盟是的,我的意思是钥匙。。。也许我需要回去睡觉了。这绝对有效,这就是我问题的答案。非常感谢你!
