/**向数组中插入数据*/

var arr = new Array();

for (var i=0;i<rowNum-1;i++)
{

var mgIdV = $("select[name=scoreBean\\.sdList\\["+i+"\\]\\.mgId]").val();
var channelIdV = $("select[name=scoreBean\\.sdList\\["+i+"\\]\\.channelId]").val();
//var scoreActV = $("select[name=scoreBean\\.sdList\\["+i+"\\]\\.scoreAct]").val();
//var scoreTypeV = $("select[name=scoreBean\\.sdList\\["+i+"\\]\\.scoreType]").val();
//var str = scoreTypeV+mgIdV+channelIdV+scoreActV;
var str = mgIdV+channelIdV
arr.push(str);

}

/**判断数组中舒服又重复数据*/

var nary=arr.sort();
for(var j=0;j<arr.length;j++){
if (nary[j]==nary[j+1]){

return false;
}

}

方法一:

var ary = new Array("111","22","33","111");
var s = ary.join(",")+",";
for(var i=0;i<ary.length;i++) {
if(s.replace(ary[i]+",","").indexOf(ary[i]+",")>-1) {
alert("数组中有重复元素：" + ary[i]);
break;外语屋
}
}
方法二:

var ary = new Array("111","22","33","111");
var nary=ary.sort();
for(var i=0;i<ary.length;i++){
if (nary[i]==nary[i+1]){
alert("数组重复内容："+nary[i]);
}
}
