我想在我的挖掘函数中添加更多的drops

Question

所以我有一个工作按钮，添加经验到我的总经验，然后有机会给你一个点击青铜。我想当我的mininglv >=10的银色被添加到它。

我尝试了另一个if语句(可能格式错误)，即if (mininglv，>=10 && mininglv < 20)，然后重复青铜和挖矿exp的代码行，然后添加一个银色随机数。我想不出如何将银牌加到点击按钮获得的几率中，并给它0.25的几率。

这是我的javaScript代码：

var Bronzechance = 0.5
var Silverchance = 0.25

function Miningaction() {
    if (MiningCexp < NextMaxMiningExp && Mininglv >= 1) {
        MiningCexp = MiningCexp + 1;
        if (Math.random() < Bronzechance)
        Bronze = Bronze + 1
    document.getElementById("Bronze").innerHTML = Bronze;
    document.getElementById("MiningCexp").innerHTML = MiningCexp;
} 
if(Mininglv >=10 && Mininglv <20){
    MiningCexp = MiningCexp + 1;
    if (Math.random() < Silverchance){
        Silver = Silver + 1;
    }
    document.getElementById("Bronze").innerHTML = Bronze;
    document.getElementById("Silver").innerHTML = Silver;
    document.getElementById("MiningCexp").innerHTML = MiningCexp;

} else {
    Mininglv = Mininglv + 1
    MiningCexp = 0
    Mining = Mining + 1
    NextMaxMiningExp = NextMaxMiningExp * 1.5;
    document.getElementById('MiningMexp').innerHTML = NextMaxMiningExp;
    document.getElementById('Mininglv').innerHTML = Mininglv;
    document.getElementById('MiningCexp').innerHTML = MiningCexp;
    document.getElementById('Mining').innerHTML = Mining;
}

}

Html代码：

 Bronze: <span id="Bronze">0</span>
 <br />
 Silver: <span id="Bronze">0</span>

<button onclick="Miningaction()"><img src="cave.png" alt="cave" 
height="45" width="45"> </button>

我希望当按钮点击时，采矿水平是10或更高，但不高于20，有机会给你银牌。但是实际的输出我不能让silver丢弃。

这就是你要找的吗？

var Bronzechance = 0.5;
var Silverchance = 0.25;
var Bronze = 0;
var Silver = 0;

function Miningaction() {
    MiningCexp = MiningCexp + 1;
    if (Mininglv >= 1) {
        if (Math.random() < Bronzechance)
            Bronze = Bronze + 1;
        document.getElementById("Bronze").innerHTML = Bronze;
        document.getElementById("MiningCexp").innerHTML = MiningCexp;

    }

    if(Mininglv >=10 && Mininglv < 20){
        if (Math.random() < Silverchance){
            Silver = Silver + 1;
        }
        document.getElementById("Silver").innerHTML = Silver;
        document.getElementById("MiningCexp").innerHTML = MiningCexp;

    if(MiningCexp >= NextMaxMiningExp)
        Mininglv = Mininglv + 1;
        MiningCexp = 0;
        Mining = Mining + 1;
        NextMaxMiningExp = NextMaxMiningExp * 1.5;
        document.getElementById('MiningMexp').innerHTML = NextMaxMiningExp;
        document.getElementById('Mininglv').innerHTML = Mininglv;
        document.getElementById('MiningCexp').innerHTML = MiningCexp;
        document.getElementById('Mining').innerHTML = Mining;
    }
}
