Duplicate checking in an Array. please help

I am new to JavaScript programming. Could any one help me in solving this problem? My problem is to find the duplicate value in the array.

I have a single dimension array with the following data stored on it.

[COLOR=Magenta]a[0] = 1~1~10[/COLOR]
a[1] = 1~2~11
a[2] = 1~3~15
a[3] = 1~4~19
a[4] = 0~5~10
[COLOR=Magenta]a[5] = 1~6~10[/COLOR]

Here in my case a[0] and a[5] is duplicate because i am using 1 or 0 for active and deactivate purpose a[4] is deactivate value so we can ignore the 10 in this. so in my case 10 is repeated twice on a[0]and a[5] not a[4], so its duplicate value. can any one help me to solve this.
Thanks you.

@Mr_JAug 03.2006 — Done something similar

[code=php]<script type="text/javascript">

a=new Array()

a[0] = "1~1~10"
a[1] = "1~2~11"
a[2] = "1~3~15"
a[3] = "1~4~19"
a[4] = "0~5~10"
a[5] = "1~6~10"

str=""

for(var i=0;i<a.length;i++){

temp1=a[i].split("~")

for(var j=i+1;j<a.length;j++){

temp2=a[j].split("~")

if(j!=i&&temp1[0]==temp2[0]&&temp1[2]==temp2[2]){

str+="Index "+i+" = "+temp1+"n"
str+="Index "+j+" = "+temp2+"n"

}


}

}

alert(str)

</script>

[/code]
