javascript - jQuery setting & getting localstorage data for dropdowns & input's -

-

i'm trying make simple form page have localstorage functionality restore settings/input after page has been closed/reloaded.

i've attempted make start still learning there mistakes , can't work.

  • if change made name input field should update localstorage new name.
  • if change made of dropdown (selector? option?) fields should update localstorage new value.
  • on page load should automatically restore of values.
  • the "clear" button should only reset dropdown (selector? option?) fields blank, should not reset name field.

example: https://jsfiddle.net/5gam3b6f/

$(document).ready(function () {     $.each($("select"), function (index, value)) {         localstorage.getitem($(this).attr(“id”));     }; });  $("select").on("change", function () {     localstorage.setitem($(this).attr(“id”), $(this)); });

i haven't managed start on name input field or clear function yet because can't first 1 work.

i rather not use external libraries complicated get, nothing else needed.

the below work you:

here working jsfiddle

jquery

$('.uselocalselect').change(function () {     var key = $(this).attr('id');     var value = $(this).val();     localstorage.setitem(key, value) });  // use timer text fields , localsotrage set 2 seconds after user stops typing instead of after each keystroke var t = ''; $('.uselocalinput').keyup(function () {     cleartimeout(t);     var key = $(this).attr('id');     var value = $(this).val();     t = settimeout(function () {         localstorage.setitem(key, value)     }, 2000); });  $('.uselocal').each(function () {     var key = $(this).attr('id');     if (localstorage.getitem(key)) {         $(this).val(localstorage.getitem(key));     } });  $('.clearlocalselect').click(function () {     $('.uselocalselect').each(function () {         $(this).val('');         var key = $(this).attr('id');         localstorage.removeitem(key);     }); });

html

<label style="color: #01acee; font: bold 14px tahoma;">input &nbsp;&nbsp;&nbsp;     <input class="uselocal uselocalinput" id="testinput" size="40" type="text" name="website" value="" required/> </label> <br/> <br/> <label style="color: #01acee; font: bold 14px tahoma;">select</label> <select class="uselocal uselocalselect" id="testselect" name="start_date">     <option value="">select one...</option>     <option value="january">january</option>     <option value="february">february</option>     <option value="march">march</option>     <option value="april">april</option>     <option value="may">may</option>     <option value="june">june</option>     <option value="july">july</option>     <option value="august">august</option>     <option value="september">september</option>     <option value="october">october</option>     <option value="november">noember</option>     <option value="december">december</option> </select> <br/> <br/>     <input type="button" class="clearlocalselect" value="clear selects"/>

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
