Deleting Duplicate Records 1

[arpan]

An HTML Form has two textboxes. Suppose a user enters 23, 45, 68, 99 in the 1st textbox & in the 2nd textbox, he enters 54, 68, 78, 94. Note that in the 2 textboxes, 68 is common. What I want is under such circumstances, 68 should automatically get deleted from the 2nd textbox (as it is already present in the 1st textbox). How do I do this?

Thanks,

Arpan

YOu keep coming up with fun ones. Will the values always be numeric? Will they always be separated by a comma?

Can they enter "68" (or whatever) a number of times in the first box, or do you want that restricted too?

"Fun" ones or the "funny" ones?? What do you mean by "fun" ones? Anyway w.r.t. your 2 doubts, the answers of both the doubts is yes i.e. the values will always be numeric & will always be seperated by a comma? Any other doubts?? I will be happy to clarify them.

Thanks,

arr2 = field2.value.split(&quot;,&quot

arr2.splice(y,1)

Whatever number it is, it will appear only once in the 1st textbox. But it can appear any number of times in the 2nd textbox. Is such cases, all the &quot;68&quot;s should be deleted from the 2nd textbox.

Thanks wolf for your code. It works properly but still a problem exists. If &quot;68&quot; (as per the e.g. I had given) is the 1st number in either the 1st or the 2nd textbox, it does not get deleted from the 2nd textbox (though 68 is present in the 1st textbox). Any workaround to fix this??

hmm- I can't duplicate consistantly - but an extra space could be causing the problem. Fix it like this...

<script>
function checkVals(){
field1 = document.getElementById(&quot;in1&quot
field2 = document.getElementById(&quot;in2&quot

arr1 = field1.value.split(&quot;,&quot
arr2 = field2.value.split(&quot;,&quot

for (x=0; x<arr1.length; x++){
for (y=0; y<arr2.length; y++){
if(parseInt(arr1[x]) == parseInt(arr2[y])){
arr2.splice(y,1)
}
}
}
field2.value = arr2
}
</script>
