How can I implement Autocomplete without a dropdownlist? I'd like for the autocomplete to fill in the remaining letters in the textbox in an alternate grey, as shown
NB: I'm not looking for the normal JQuery UI Autocomplete plugin.
How to. The Select Autocomplete component is a mix between a <select> element and a text input. The focus on the input triggers a selection dropdown; by typing in the input element, you'll filter the select options. This component uses the <select> element to create (in JS) the dropdown.
You can try HTML <datalist> tag for autocomplete dropdown.
A user types into an input, and the autocomplete “completes” their thought by providing full terms or results: this is the very base of an autocomplete experience. For example, try typing the letter “m” in the search box below. You can select suggestions like “macbook” and “mobile”.
jQuery.suggest.js
The discussion here has lead to the development of a jQuery plugin, which you can find here: http://polarblau.github.com/suggest/.
All code and examples below are therefore outdated but might still be interesting for some.
I've been very interested in the outcome of this question, but it seems that hasn't been anything found yet.
I've thought about writing my own solution for a little while now and I can tell you what I had in mind (and this is only in my head right now and definitely not anyhow tried out):
HTML:
<div id="search-container">
<input type="text" name="search" id="search" />
<input type="text" disabled="disabled" id="suggestion" />
</div>
CSS:
#container {
position: relative;
}
#search {
position: relative;
color: #000;
z-index: 10;
background: transparent;
// border, etc....
}
#suggestion {
position: absolute;
top: 0;
left: 0;
z-index: 0;
color: #ccc;
border: none;
// ...
}
The use Javascript 'onkeydown' to match the first (sort criteria are important here) word from a list that shares the already typed letters in the beginning of the word and place it in the disabled input field #suggestion
. If the user hits enter, the word from #suggestion
will be transfered into the #search
input field and possibly the form submitted.
If I find the time I'll try to make it a working jQuery plugin — let's see. But maybe you get the idea?
EDIT
I've tried my idea and it seems to work in it's simplest form quite okay. I'll release it as a small jQuery plugin soon at my github account. I'll drop you a note here, once I'm done. Or go ahead and give it a crack yourself and let me know how it's coming.
Here's the code that I ended up using (parts of it would probably be dynamically generated):
HTML:
<div id="search-container">
<input type="text" name="search" id="search" />
<input type="text" disabled="disabled" id="suggestion" />
</div>
CSS:
* { margin: 0; padding: 0; }
#search-container {
position: relative;
}
#search-container input {
padding: 5px;
font-size: 1.2em;
width: 200px;
}
#search {
position: relative;
color: #000;
z-index: 10;
border: 1px solid #666;
background: transparent;
}
#suggestion {
position: absolute;
top: 0;
left: 0;
z-index: 0;
color: #ccc;
background: transparent;
border: 1px solid #fff;
}
JAVASCRIPT:
$(function() {
var haystack = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$('#search').keyup(function(e) {
// 'enter' key was pressed
var $suggest = $('#suggestion');
var code = (e.keyCode ? e.keyCode : e.which);
if(code == 13) {
$(this).val($suggest.val());
$suggest.val("");
return false;
}
// some other key was pressed
var needle = $(this).val();
// is the field empty?
if (!$.trim(needle).length) {
$suggest.val("");
return false;
}
// compare input with haystack
$.each(haystack, function(i, term) {
var regex = new RegExp('^' + needle, 'i');
if (regex.test(term)) {
$suggest.val(needle + term.slice(needle.length));
// use first result
return false;
}
$suggest.val("");
});
});
});
