jQuery pughound.js is a small, easy and customizable jQuery autocomplete plugin for the text field that has the ability to fetch suggestions from an external data source you specify.

Autocomplete

Documentation

pughound-js

A simplistic plugin for rendering suggestive search results from a remote data source

why ?

Because other implementations are annoying, overly complex and didn't have all the options required for the destination application

requirements

assumed referenced in the destination project somewhere:

  • jQuery >= v1.6
  • jQuery-Throttle-Debounce >= v1.1 (only required when you wish to make use of the input debounce feature)

how to use

reference it

check for the most recent release version within this repo and include the script tags below noting to replace the @pughound_ver with latest.

the jsDelivr CDN picks up releases directly from this repo.

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery-throttle-debounce/1.1/jquery.ba-throttle-debounce.min.js"></script> <script type="text/javascript" src="https://cdn.jsdelivr.net/gh/itb2k13/pughound-js@{@pughound_ver}/jquery-pughound.min.js"></script> <link href="https://cdn.jsdelivr.net/gh/itb2k13/pughound-js@{@pughound_ver}/jquery-pughound.min.css" rel='stylesheet' type='text/css' />

mark it up ("target element")

apply the class 'pughound' to a target input text element

<input type="text" id="keyword_search" name="keyword_search" class="pughound" placeholder="Search for things..." />

configure it (biggly simple)

    $(document).ready(function () {          var options = {             remotesrc: 'https://www.mydomain.com/api/example.results.json',             mapping: function (n, i) { return { count: n.CountForDisplay, text: n.Presentation, url: n.Url }; },             urlformatting: function (url) { return url; }         };          $('.pughound').pughound(options);      }); 

configure it (lessly simple)

	$(document).ready(function () {  		var options = { 			customclass : '', 			debounce : 250,  			minchars : 3,  			fadespeed : 160,  			highlightsearch : true,  			closeonemptyterm : true,  			closeonescape : true,  			closeonlinkclicked : false, 			showonfocus : true, 			loopsaround : true, 			autocomplete : 'off', 			autofocus : true, 			settextonclick : true, 			remotesrc : '',  			resultstoshow : 12,  			showcounts : true, 			countformat : '({0})', 			ignorekeycodes : [27, 39, 40, 32, 37, 38, 9, 17, 18, 13], 			mapping : function(n,i){return {count : n.Count, text : n.Text, url : n.Url, id : n.Id }; }, 			urlformatting : function(url){return url;}, 			onanchorclick: function (data) { $('#MyFieldId').val(data.Id); } 		};  		$('.pughound').pughound(options); 	});

config options

most important

remotesrc

the url from which results will be obtained (see section 'Remote Sources' further down)

mapping

allows a custom JS function to be defined so that remote data sources can be mappend into an object structure that pughound understands. (see section 'Remote Sources' further down)

urlformatting

allows customization of the result-set hrefs (see section 'Remote Sources' further down)

onanchorclick

allows specification of a custom function which will execute on the anchor click and has access to the items data element

least important

customclass

each pughound element will be given this class allowing for CSS style differentiation when multiple instances of the pughound targets appear on the same page

debounce (miliseconds)

controls the latency of the user input keydown to trigger a remote call

minchars

how may characters must be entered before a remote call for results is made

fadespeed (miliseconds)

how fast the results container fades in and out (0 = off/nofade/instant)

highlightsearch

whether the results should highlight the search term if found within the result string. if so, a custom class is applied allowing for style overloading

closeonescape

whether the results container should close on user pressing the ESCAPE key

closeonlinkclicked

whether the results container should close when one of the search results is clicked

showonfocus

whether the results container will re-show itself if the target element loses and re-gains focus

loopsaround

whether the focus returns to the top element in the result set upon reaching the last element using the DOWN key

autocomplete

can be used to disable the browser auto-complete feature of the target element thus preventing annoying webkit overlays

autofocus

attemps to force the browser to auto-focus the target element upon page load. not always 100% successful depending on other conflicting JS logic.

settextonclick

upon the user clicking an element in the result-set, this setting determines whether the target element should recieve the full href text of the clicked element.

triggers both jQuery events in this order: 'change' and 'input'

resultstoshow

how many results from the remote data source to show in the result-set

showcounts

whether to show the counts returned by the remote data source (see more on the 'Remote Sources' further below)

countformat

if counts are shown, allows customization of the presentation of the number: e.g. (50) or [50] or -50-

ignorekeycodes

prevents a remote call if the keydown keycode exists in the defined list. prevents CTRL, ALT, SHIFT from triggering unwanted calls.
