hi there. ok i have developed several split arrays from several strings. like this

var s1=page-1 page-2 page-3;
var s2=page-1 page-2 page-3;
var s3=page-1 page-2 page-3;

var spt=new Array()
spt[0]=s1.spit(" ");
spt[1]=s2.spit(" ");
spt[2]=s3.spit(" ");

ok what i want is to search for the word page-3 in the srtings and count the number of times it has occured, put the result in a text box.(the textbox bit is easy but getting the count......)

var s1="page-1 page-2 page-3";
var s2="page-1 page-2 page-3";
var s3="page-1 page-2 page-3";

var spt=new Array()
spt[0]=s1.split(" ");
spt[1]=s2.split(" ");
spt[2]=s3.split(" ");

var count = 0;
var regEx = new RegExp("page-3");
for (var i=0; i<spt.length; i++) {
for (var j=0; j<spt[i].length; j++) {
if (regEx.test(spt[i][j])) count++;
}
}
alert(count);

let me rephrase it like this

var s1=page-1 page-2 page-3;
var s2=page-4 page-5 page-6;
var s3=page-7 page-8 page-9;

var spt=new Array()
spt[0]=s1.spit(" ");
spt[1]=s2.spit(" ");
spt[2]=s3.spit(" ");

what i need is to display the number of pages available, by getting the number of occurences of the word page. now if there is a way one can count the word "page" alone ignoring the rest "-1..."

the solution you gave me befor only brings back the size of the spt[] array in this case it alerts 3.

sorry for the mistake befor.pliz help

Um, that's what you asked for.
ok what i want is to search for the word page-3 in the srtings

Change
var regEx = new RegExp("page-3");
To
var regEx = new RegExp("page-");
