Can anyone help me modify my script? I was trying to produce a simple-cross browser search option that would search / highlight the text on just one page - much like the ctrl+f function.
Currently a vistor would need to click "search page" over and over again to highlight each instance of the same word, one at a time. I would like just one click and all examples of that term to be highlighted. For instance, all the examples of "child" would be highlighted at once.
<script language="JavaScript">
var n = 0;
function findInPage(str) {
var txt, i, found;
if (str == "") {
return false;
}
// Find next occurance of the given string on the page, wrap around to the
// start of the page if necessary.
if (window.find) {
// Look for match starting at the current point. If not found, rewind
// back to the first match.
if (!window.find(str)) {
while (window.find(str, false, true)) {
n++;
}
} else {
n++;
}
// If not found in either direction, give message.
if (n == 0) {
alert("Not found.");
}
} else if (window.document.body.createTextRange) {
txt = window.document.body.createTextRange();
// Find the nth match from the top of the page.
found = true;
i = 0;
while (found === true && i <= n) {
found = txt.findText(str);
if (found) {
txt.moveStart("character", 1);
txt.moveEnd("textedit");
}
i += 1;
}
// If found, mark it and scroll it into view.
if (found) {
txt.moveStart("character", -1);
txt.findText(str);
txt.select();
txt.scrollIntoView();
n++;
} else {
// Otherwise, start over at the top of the page and find first match.
if (n > 0) {
n = 0;
findInPage(str);
}
// Not found anywhere, give message. else
alert("Not found.");
}
}
return false;
}
