splice and split arrays

cathiec · Nov 3, 2003

for(var j=0;j<3;j++){

var thisOne = Math.floor(Math.random( )* allNums.length);
ran_number=allNums[thisOne];
allNums.splice(thisOne,1);
ran_number = ran_number + "";
for(var i = tbl.rows.length-1; i >=0; i--){
if(tbl.rows.id == ran_number){
tbl.deleteRow(i);
alert(ran_number);

}
}

i want to split the array allNums and when i use the following code i get an error: Object does not support this property or method:

var splitString = new Array();
splitString = allNums.split(","
alert(splitString[0]);
alert(splitString[1]);
alert(splitString[2]);
alert(splitString[3]);
alert(splitString[4]);

I threw together this example of an array creation
and usage of your code:

Code:

<html><head><script>
var allNums = new Array(1,2,3);
function ckarray() {
for(var j=0;j<3;j++){
  var thisOne = Math.floor(Math.random( )* allNums.length);
   if(thisOne<0) {thisOne = 0;}
  ran_number=allNums[thisOne];
  allNums.splice(thisOne,1);
  ran_number = ran_number + &quot;&quot;;
  alert('ran_number is ' +ran_number); alert('allNums length is ' +allNums.length);}
}
</script></head><body>
<a href=&quot;#&quot; onClick=&quot;javascript:ckarray();&quot;>TEST</a>
</body></html>

Also the way you are using split is for a string object
not an array, if your intention is to create the allNums
array using split this is the how you would do that.

var str = '1,2,3';
var allNums = str.split(",&quot

;
then you have an array but usage here would need to
be joined with usage of parseInt because you originally
declared these values as a string.
