全文搜索代码，仅供参考，代码转自本坛：
<script language="JavaScript">
var NS4 = (document.layers);
var IE4 = (document.all);
var win = window;
var n = 0;
function findInPage(str) {
var txt, i, found;
if (str == "")
return false;
if (NS4) {
if (!win.find(str))
while(win.find(str, false, true))
n++;
else
n++;
if (n == 0)
alert("没有找到。");
}
if (IE4) {
txt = win.document.body.createTextRange();
for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) {
txt.moveStart("character", 1);
txt.moveEnd("textedit");
}
if (found) {
txt.moveStart("character", -1);
txt.findText(str);
txt.select();
txt.scrollIntoView();
n++;
}
else {
if (n > 0) {
n = 0;
findInPage(str);
}
else
alert("没有找到。");
}
}
return false;
}
</script>
<form name="search" onSubmit="return findInPage(this.string.value);">
<font size=3><input name="string" type="text" size=15 onChange="n = 0;"></font>
<input type="submit" value="搜索"> 查找页面关键字
</form>Top
