我有一个骰子函数，它将骰子的总和相乘，将总和存储在变量中，然后打印出总和。没问题，但是当我运行应用程序两次。第二个应用程序会影响第一个应用程序的总和。
我尝试使用localStorage，但没有任何效果。这是我在两个应用程序中显示不同结果的最接近的
我希望能够运行多个应用程序，但不能泄漏信息。 有什么提示吗？
jsFiddle http://jsfiddle.net/dymond/gUL9U/＆lt; - 运行应用程序两次，你就会发现问题。
function dicesides_func(nr){
// go to dice-window-wrapper again
// this could be put in a seporate functon
var elementToAddDice=" dice-window-wrapper ",
obj=this, // using this here that's why it's called wiht
dice,i=0,total=0; // all the dice in this dice window
// dicesides_func.call to set the right this context
if(nr)
{
while((" "+obj.className+" ").indexOf(elementToAddDice)==-1){
obj=obj.parentNode;
}
obj=obj.getElementsByTagName("ul")[2];
var dicessides = createElementWithClass('li',nr);
obj.appendChild(dicessides);
// calculate total (can do in a seporate function)
dice = obj.getElementsByTagName("li");
}
else
{
dice = document.getElementsByClassName("dice");
}
for(i=0;i<dice.length;i++){
total=total+getNumberForClass(dice[i].className);
}
//alert(total);
var wrapper = document.getElementsByClassName("dice-toolbar-counter-wrapper")[0];
while (wrapper.hasChildNodes()) {
wrapper.removeChild(wrapper.lastChild);
}
var ttl = total.toString();
var arr = [];
for (var i = 0;i<ttl.length;i++) {
var digit = ttl[i];
var newelem = createElementWithClass('li',"side-" + ttl[i]);

选择正确的包装器，您应该没问题：在创建应用程序时可能使用全局计数器变量，以便稍后了解您当前使用的应用程序？
本节选择第一个包装器：
var wrapper = document.getElementsByClassName("dice-toolbar-counter-wrapper")[0];
如果我将此0更改为1而不是upp upp应用程序no 2而不是1，因为您实际上是在包装器数组中选择[0]键。
Snyggt btw！
