How do I make the result appear on the same page instead of a new window?

JavaScript
1

I found a search script that I can almost use in my Android app. However, the script opens up a new page, and I want the search results to appear on the same page. How do I change the script to keep the results on the same page? There should be no window.open in the script, I know that much!

    <script language="Javascript">

<!-- This script from: http://javascript.internet.com/miscellaneous/site-search.html  -->

var item = new Array();

/* Here is where all the magic happens.  
    Just enter as many additional pages that
    that you want to search, then fill in the
    additional listings for each page.
*/

// "Page Name","path","Page Title","Many,Key,Words","Descriptive Comments"

c=0; item[c]=new Array("0300.html","","A debtor to mercy alone","other searchable text here","by Augustus Montague Toplady.");
c++; item[c]=new Array("0301.html","","A lamp in the night","other searchable text here","by Daniel Webster Whittle.");
c++; item[c]=new Array("0302.html","","A mighty Fortress is our God","other searchable text here","by Martin Luther.");
c++; item[c]=new Array("0303.html","","A mind at perfect peace with God","other searchable text here","by Catesby Paget.");
c++; item[c]=new Array("0304.html","","A wonderful Savior is Jesus my Lord","other searchable text here","by Fanny Crosby.");

page="<html><head><title>Search Results</title></head><body bgcolor='white'><center><table border=0 cellspacing=10 width=80%>";

function search(frm) {
win = window.open("","","scrollbars");
win.document.write(page);
txt = frm.srchval.value.split(" ");
fnd = new Array(); total=0;
for (i = 0; i < item.length; i++) {
fnd[i] = 0; order = new Array(0, 4, 2, 3);
for (j = 0; j < order.length; j++)
for (k = 0; k < txt.length; k++)
if (item[i][order[j]].toLowerCase().indexOf(txt[k]) > -1 && txt[k] != "")
fnd[i] += (j+1);
}
for (i = 0; i < fnd.length; i++) {
n = 0; w = -1;
for (j = 0;j < fnd.length; j++)
if (fnd[j] > n) { n = fnd[j]; w = j; };
if (w > -1) total += show(w, win, n);
fnd[w] = 0;
}
win.document.write("</table><br>Total found: "+total+"<br></body></html>");
win.document.close();
}
function show(which,wind,num) {
link = item[which][1] + item[which][0]; 
line = "<tr><td><a href='"+link+"'>"+item[which][2]+"</a> Score: "+num+"<br>";
line += item[which][4] + "<br>"+link+"</td></tr>";
wind.document.write(line);
return 1;
