The following is just a demonstration of how you would link to search.htm from other pages:<br><br>
<!-- if you want to link from another page, just copy the JavaScript code below
and paste it into your other page -->
<script language="JavaScript">
<!--
// enter full or relative URL to your search page
var search_htm_url = "your_search_page_name.htm";
function searchPage() {
if ((document.searchpage.keyword.value.length == 0)
|| (document.searchpage.keyword.value == " ")) {
alert("First you must enter a keyword to search for.");
} else {
sel = document.searchpage.and_or.selectedIndex;
location.href = search_htm_url + "?"
+ escape(document.searchpage.keyword.value)
+ (sel==0?"&and":(sel==2?"&exact":"&or"));
}
return false;
}
document.write('<form name="searchpage" onSubmit="return searchPage()">'
+'Search for: <input type="text" size=15 name="keyword"> '
+'<input type="button" value="Search" onClick="searchPage()"><br>'
+'<select name="and_or" size=1><option>find all words (AND)<option>find any word '
+'(OR)<option>exact match</select><br>"*" wildcards are valid</form>');
// -->
</script>
<br><br>
Or you can just use direct links. For instance, if you wanted to search for the keyword "javascript", then you would link to <a href="search.htm?javascript">search.htm?javascript</a>. Or search for "javascript" or "perl": <a href="search.htm?javascript%20perl&or">search.htm?javascript%20perl&or</a>. Or for "javascript" and "perl": <a href="search.htm?javascript%20perl&and">search.htm?javascript%20perl&and</a>. Or for the exact phrase "javascript perl": <a href="search.htm?javascript%20perl&exact">search.htm?javascript%20perl&exact</a>. (note that %20 is the URL escaped form of a space).
