javascript - Issue with changing label color -

-

i not web developer trying fix in code, please excuse me if overlooking something.

i trying disable checkbox , label when checkbox checked.

this how html looks like:

<dl id="someparent"> <dd><input type="checkbox" name="checkbox1" id="checkbox1"/> <label for="checkbox1" data-localize="sometext.name1" class="checkbox1">   </label> </dd><dd> <input type="checkbox" name="checkbox2" id="checkbox2"/> <label for="checkbox2" data-localize="sometext.name2" class="checkbox2"> </label> </dd><div class="clear"></div></dl>

js:

$('#checkbox1').click(function() {  if( $("#checkbox1").is(':checked') ){     $('#checkbox2').attr("disabled", true);     $('label[data-localize="sometext.name2"]').css("color", "red"); //this doesn't work    } else {     $('#checkbox2').removeattr('disabled');     //code change label color. how, access data-localize="sometext.name2"? sometext.name2 defined in json file string, sometext.name2: "this printed label 1"   } });                              $('#checkbox2').click(function() {  if( $("#checkbox2").is(':checked') ){    $('#checkbox1').attr('disabled', true);     //code change label color. how, access data-localize="sometext.name1"? sometext.name1 defined in json file string, sometext.name1: "this printed label 2"     } else {        $('#checkbox1').removeattr('disabled');        $('label[data-localize="sometext.name1"]').css("color", "black"); //this doesn't work      } }); //my issue can not access , hence change color of "sometext.name1/2" label/text next checkbox1/2. disabling checkbox not issue greying out label next checkbox issue.

in original code, program replaces sometext.name1/2 mapping string json file label.

i can make work if use label in html(as seen in jsfiddle have used checkbox1,2 label), not when code replaces data-localize string json file. checboxes working correctly label doesnt change color.

note: can't change architecture of code, therefore have use data-localize only. also, question not changing color of label, how access , change label when data-localize used.

also, checkbox1 , checkbox2 labels not in original code instead generated dynamically replacing sometext.name1 , sometext.name2.

example: https://jsfiddle.net/w8s9rlme/34/

i simplify/generalize code (make agnostic data-localize attribute) bit , use class setting colors.

$('#someparent').on('change', ':checkbox', function(){      var otherdd = $(this).closest('dd').siblings();              otherdd.find(':checkbox')             .prop('disabled', this.checked);                 otherdd.find('[data-localize]')             .toggleclass('disabled-checkbox', this.checked);  });
.disabled-checkbox{    color:red;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <!-- ^^ added demo ^^ -->    <dl id="someparent">    <dd>      <input type="checkbox" name="checkbox1" id="checkbox1" />      <label for="checkbox1" data-localize="sometext.name1" class="checkbox1">checkbox1</label>    </dd>    <dd>      <input type="checkbox" name="checkbox2" id="checkbox2" />      <label for="checkbox2" data-localize="sometext.name2" class="checkbox2">checkbox2</label>    </dd>    <div class="clear"></div>  </dl>

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
