我不断得到

未捕获的类型错误：字符串不是函数

。有什么线索吗？

您试图调用字符串变量上的函数

var func='dis'+原件

所以func现在是一个字符串，而不是一个可调用的函数

如果结果字符串func实际上是一个函数名，则可以执行以下操作：

window[func]();

使用字符串变量调用func。

一旦值被传递到一个区间，就不能更改它们，需要一个递归函数来实现。为什么会这样，如何实现？：）@adeneofunc（）不是函数。你为什么把它叫做函数？你能给我举个例子说明我还能怎么做吗@Salgad你能在最后一位尝试eval（func）而不是'func（）'吗？现在，一旦我放置第二个塔，第二次调用间隔，它就不起作用了。那么，如果比较变量func，它是否与全局函数名匹配？如果是这样的话，上面的方法应该会起作用。我不太明白你可以用两种方法中的一种来处理javascript函数。dis1（）；或窗口[“dis1”]（）；假设存在名为dis1的全局函数。但是，请稍候，每当有新的setinterval时，如果我将

func（）

设置为全局函数，则每次都会覆盖。有解决办法吗？

setInterval(function(){
    var func = 'dis' + original;
    func();

    alert(original); //for some reason
}, 1800);

window[func]();
