JS判断一个数组中是否有重复值的三种方法方法一:
var ary = new Array("111","22","33","111")
var s = ary.join(",")+","
for(var i=0i<ary.lengthi++) {
if(s.replace(ary[i]+",","").indexOf(ary[i]+",")>-1) {
alert("数组中有重复元素：" + ary[i])
break
}
}
方法二:
var ary = new Array("111","22","33","111")
var nary=ary.sort()
for(var i=0i<ary.lengthi++){
if (nary[i]==nary[i+1]){
alert("数组重复内容："+nary[i])
}
}
方法三:
function isRepeat(arr){
var hash = {}
for(var i in arr) {
if(hash[arr[i]])
return true
hash[arr[i]] = true
}
return false
}
