javascript - Less redundant way of putting this -

i have code stores checked value of checkbox in localstorage.

how shrink it?

$('#ospone').click(function(e){     savesettings(e["currenttarget"]["id"], e["currenttarget"]["checked"]);     getsettings(e["currenttarget"]["id"]); });  $("#osptwo").click(function(e){     savesettings(e["currenttarget"]["id"], e["currenttarget"]["checked"]);     getsettings(e["currenttarget"]["id"]); });  $("#ospthree").click(function(e){     savesettings(e["currenttarget"]["id"], e["currenttarget"]["checked"]);     getsettings(e["currenttarget"]["id"]); });  $("#ospfour").click(function(e){     savesettings(e["currenttarget"]["id"], e["currenttarget"]["checked"]);     getsettings(e["currenttarget"]["id"]); }); 

settings functions:

function savesettings(aval, akey){     localstorage.setitem(aval, json.stringify(akey)) }  function getsettings(akey){     var str = localstorage.getitem(akey);     return json.parse(str); } 

there couple of ways it. i've put them in order of best way of doing in opinion.

1. classes

apply class current elements (#ospone - #ospfour). example, .settingsbtn.

html

<input type="checkbox" id="#ospone" class="settingsbtn" /> <input type="checkbox" id="#osptwo" class="settingsbtn" /> <input type="checkbox" id="#ospthree" class="settingsbtn" /> <input type="checkbox" id="#ospfour" class="settingsbtn" /> 

javascript

$('.settingsbtn').click(function(e) {     savesettings(e.currenttarget.id, e.currenttarget.checked);     getsettings(e.currenttarget.id); }); 

2. select checkboxes

assuming using checkboxes , on each 1 want update settings on click, can select checkboxes accordingly.

$('input[type=checkbox]').click(function(e) {     savesettings(e.currenttarget.id, e.currenttarget.checked);     getsettings(e.currenttarget.id); }); 

3. ^= selector

you can select elements have id starts osp.

$('[id^=osp]').click(function(e) {     savesettings(e.currenttarget.id, e.currenttarget.checked);     getsettings(e.currenttarget.id); }); 

4. single selector

combine selectors one.

$('#ospone, #osptwo, #ospthree, #ospfour').click(function(e) {     savesettings(e.currenttarget.id, e.currenttarget.checked);     getsettings(e.currenttarget.id); });
