Menu
What I'm looking for:
I'm working on creating an easy way for a user to search a list of people, and for results to instantly display below the search field. The results MUST display "close" results, rather than exact. For example: User searches for "Mr. Smith" and The following existing result is displayed: "John Smith" (since there is no "Mr. Smith" entry, it displayed one with the keyword "smith")
What I have:
I have a working code that lets the user enter some characters and all divs that include a string matching the input is displayed (see in jsfiddle: http://jsfiddle.net/891nvajb/5/ Code is also below) Unfortunately, this only displays results that match EXACTLY.
<body>
<input type="text" id="edit_search" onkeyup="javascript: find_my_div();">
<input type="button" onClick="javascript: find_my_div();" value="Find">
<script>
function gid(a_id) {
return document.getElementById (a_id) ;
}
function close_all(){
for (i=0;i<999; i++) {
var o = gid("user_"+i);
if (o) {
o.style.display = "none";
}
}
}
function find_my_div(){
close_all();
var o_edit = gid("edit_search");
var str_needle = edit_search.value;
str_needle = str_needle.toUpperCase();
if (str_needle != "") {
for (i=0;i<999; i++) {
var o = gid("user_"+i);
if (o) {
var str_haystack = o.innerHTML.toUpperCase();
if (str_haystack.indexOf(str_needle) ==-1) {
// not found, do nothing
}
else{
o.style.display = "block";
}
}
}
}
}
</script>

Split the words in the search string with a regex like
searchString.split(/\W/);
and do a OR search over each of the words in the resulting array.
Updated fiddle
var searchStrings = str_needle.split(/\W/);
for (var i = 0, len = searchStrings.length; i < len; i++) {
var currentSearch = searchStrings[i].toUpperCase();
if (currentSearch !== "") {
nameDivs = document.getElementsByClassName("name");
for (var j = 0, divsLen = nameDivs.length; j < divsLen; j++) {
if (nameDivs[j].textContent.toUpperCase().indexOf(currentSearch) !== -1) {
nameDivs[j].style.display = "block";
}
}
}
}
