javascript - Image hover and replace - jquery -


greetings have been trying hours , having trouble trying figure out. new javascript , jquery. example have 2 images, black , blue image. have 4 black images when hovered individually, changes img src blue, , goes black when hovered out. trying accomplish when click image/link, stay "blue". change "black" once click on other images.

here have far:
html

<a id="catlnk1" href="javascript:void(0);" onclick="loadcat(1)"><img src="/images/blogpage/published.png" onmouseover="this.src='/images/blogpage/published-active.png'" onmouseout="this.src='/images/blogpage/published.png'" alt="published" />

script

function loadcat(num)  { if (num == 1){  $("#catlnk" + num).attr("src","/images/blogpage/published-active.png");  } else if (num == 2){  $("#catlnk" + num).attr("src","/images/blogpage/upcoming-active.png");  } else if (num == 3){  $("#catlnk" + num).attr("src","/images/blogpage/opening-active.png");  } else if (num == 4){  $("#catlnk" + num).attr("src","/images/blogpage/job-active.png");  }  }

sorry if code messy, i'm new this.

it bad idea bind events inline. separate out functionality design , bind events using javascript or jquery.

i using html-5 data-attributes called data-image holds image displayed.

so html this.

html

<a id="catlnk1" href="javascript:void(0);">     <img data-image="published" src="/images/blogpage/published.png" alt="published" /> </a> <a id="catlnk2" href="javascript:void(0);">     <img data-image="upcoming" src="/images/blogpage/upcoming.png" alt="upcoming" /> </a> <a id="catlnk3" href="javascript:void(0);">     <img data-image="opening" src="/images/blogpage/opening.png" alt="opening" /> </a> <a id="catlnk4" href="javascript:void(0);">     <img data-image="job" src="/images/blogpage/job.png" alt="job" /> </a>

js

var url = "/images/blogpage/"; $('[id^=catlnk]').on({     click: function (e) {         var $currimg = $(this).find('img');         $currimg.attr('src', function (_, src) {             return url + $(this).data('image') + '-active.png';         });          // images          $allimages = $('a > img');         $allimages.not($currimg).each(function () {             $(this).attr('src', function (_, src) {                 return url + $(this).data('image') + '.png';             });         });         $currimg.addclass('clicked');         $allimages.not($currimg).removeclass('clicked');     },     mouseover: function () {         var $img = $(this).find('img');         $img.attr('src', function (_, src) {             return url + $(this).data('image') + '-active.png';         });         $img.addclass('active');     },     mouseleave: function () {         var $img = $(this).find('img');         $img.attr('src', function (_, src) {             return url + $(this).data('image') + '.png';         });         $img.removeclass('active');     }  })

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
