我对JavaScript很陌生,只是真正研究过它用于基于网络的技能计算器。 我找到了一个样本,并根据我的需要进行了调整,但是在几个不同的浏览器中进行测试后,我注意到在点击按钮时,计数器没有上升或下降,点击10次后我仍然收到消息“你已经超过了出那个技能!“然后再右键点击10次,就会给我一条消息“你已经超出了那个技能!”正如我所料,但柜台本身并没有改变。
是否有一个简单的方法可以让它在Firefox中运行,或者我应该采用另一种方式吗?
CSS:
.skillbutton {
background:url() no-repeat;
cursor:pointer;
width: 250px;
height: 12px;
border: none;
color: transparent;
}
#skill1counter {
margin-left: auto ;
margin-right: auto ;
font-size:0.6em;
}
#skill1 {
width: 250px ;
height: 12px ;
margin-left: auto ;
margin-right: auto ;
background-image:url(images/skill/skill1.png);
background-repeat:no-repeat;
}
HTML:
<div id='skill1'>
<input type="button" class="skillbutton" onclick="SkillManager.increase('skill1')" oncontextmenu="SkillManager.decrease('skill1'); return false;" value="S1" />
</div>
<div id='skill1counter' style="font-weight: bold">0</div>
剧本:
<script type="text/javascript">
var SkillManager = (function() {
var max = 50,
skills = {
skill1: {
cur: 0,
max: 10
},
skill2: {
cur: 0,
max: 10
},
skill3: {
cur: 0,
max: 10
}
},
totalUsed = 0;
var increase = function(skill) {
if (totalUsed < max && skills[skill].cur < skills[skill].max) {
skills[skill].cur++;
totalUsed++;
updateDisplay(skill, skills[skill].cur, max - totalUsed);
} else if(skills[skill].cur === skills[skill].max) {
alert("You have maxed out that skill!");
} else {
alert("You have used all your skill points!");
}
};
var decrease = function(skill) {
if (skills[skill].cur > 0) {
skills[skill].cur--;
totalUsed--;
updateDisplay(skill, skills[skill].cur, max - totalUsed);
} else {
alert("You can't decrease a skill with 0 points in it!");
}
};
var updateDisplay = function(skill, value, totalRemaining) {
document.getElementById(skill + "counter").innerText = value;
document.getElementById("remainingPoints").innerText = totalRemaining;
};
return {
decrease: decrease,
increase: increase
};
}());
</script>
另外作为一个附带问题,我如何添加一个if语句,表示“如果技能1 =小于10则技能2不能增加”或技能2增加技能1必须是10?< / p>
答案 0 :(得分:1)
首先,您缺少HTML中的元素remainingPoints
。
<div id='remainingPoints'></div>
其次,在firefox中,将innerText
替换为textContent
,它应该可以正常工作here:
var updateDisplay = function(skill, value, totalRemaining) {
if(document.all){
document.getElementById(skill + "counter").innerText = value;
document.getElementById("remainingPoints").innerText = totalRemaining;
} else {
document.getElementById(skill + "counter").textContent = value;
document.getElementById("remainingPoints").textContent = totalRemaining;
}
};
