## Show 5 sequential numbers of a clicked number

Hi all,

I have a list of sequential numbers here. How can i show the 5 numbers infront and behind a clicked number?

e.g. When i clicked on the number 0, this is the situation:

5 4 3 2 1 0 -1 -2 -3 -4 -5

So when i clicked on the number 2, it should show like this:

7 6 5 4 3 2 1 0 -1 -2 -3

Your prompt response is very much appreciated.

you can do this:

Code:
```function showNumber(nr){
return [nr+5,nr+4,nr+3,nr+2,nr+1,nr,nr-1,nr-2,nr-3,nr-4,nr-5];
}

Gozzy82's example solve it nicely.

Here is function which you can modify to increase or decrease the amount of numbers in front or behind:

Pass num as the variable:
Code:
```function createSequence(num)
{
var upper = num + 5;
var lower = num - 5;
var sequence = '';

for (var i = upper; i >= lower; i--)
{
sequence += i + (i > lower ? ', ' : '');
}

}```

Dear Gozzy82 and SparoHawk,

Here is my complete code:

Code:
```<script language="javascript">
listNumber(0);
})

function listNumber(val) {
val = parseInt(val);
var upper = val+5;
var lower = val-5;
var sequence = '';
for (var i = upper; i >= lower; i--)
{
sequence += "<span style='cursor:pointer' onclick='listNumber(\$(this).html());'>";
if (i==val) sequence += "<font weight='bold' color='#FF0000'>"
sequence += i + (i > lower ? ' ' : '');
if (i==val) sequence += "</font>"
sequence += "</span>";
}
\$('#seq_no').html(sequence);
}
</script>

<div id="seq_no"></div>```
Thanks and have a nice day
