我要比较不同长度的两个数组，如果有他们之间的共同元素显示警报或DoSomething的。

I want to compare two arrays of different length and if there's a common element between them show an alert or dosomething.

var valuesAdded= ["ab","c","d","eeef","bbc","ac","jk","df","ss"]
var valuesToadd= ["aaa","jk","eeef","ddd","d","ab","rs"]

所以无论values​​Added可以更大或values​​Toadd可以更大，但我想是比较它们已存在于上述情况下eeef的元素，D，JK，AB，并显示一个提醒这些已经在values​​Added等

so either valuesAdded can be larger or valuesToadd can be larger, but what i want is compare them for those element that already exists in the above case "eeef","d","jk","ab" and show an alert that these are already in valuesAdded etc.

我想在常规的JavaScript或usingdojo做。

I would like to do in regular javascript or usingdojo.

能否请你在这方面的帮助，你的帮助将是AP preciated。

Can you please help in this regards, your help will be appreciated.

感谢

推荐答案

真的没什么具体的Javascript这里：

Nothing really Javascript specific here:

for(var i = 0; i<arr1.length; i++){
    for(var j=0; j<arr2.length; j++){
        if(arr1[i] === arr2[j]){
            //do something
        }
    }
}
