Jquery on() load event on a single element -

-

i'm sorry if question has been asked, didn't find solution.

i have 3 radios elements , want check value when selection changes , when page loads.

i using on() function.

my problem change event triggered.

here current code :

$('.user').on('load change', function(){   if($(this).val() == 'client'){  $('#user_parent').removeattr('disabled').closest('tr').show(200); }else{   $('#user_parent').attr('disabled', 'disabled').closest('tr').hide(200); } });"

i tried replace load ready, failed too. problem ? isn't load event available single element ?

the code placed in $(document).ready(...), , elements displayed when page sent.

thanks

the load event called moment child elements of listened element loaded. in case might before ready event called, rendering handler load (which appended after document.ready) useless.

for reference see jquery api find following:

the load event sent element when , sub-elements have been loaded. event can sent element associated url: images, scripts, frames, iframes, , window object.

this means need url, can listen load event. have not provided further code assume indeed have url can listen to.

this might probable cause though. if not have url associated (at least one) child element(s) there no load event can listen to.

try instead:

$(document).ready(function(){    checkuserval();    $('.user').on('change', checkuserval); });  var checkuserval = function(){   //do check   if($('.user').val() == 'client'){       $('#user_parent').removeattr('disabled').closest('tr').show(200);   }else{      $('#user_parent').attr('disabled', 'disabled').closest('tr').hide(200);   } };

i made code method improved readability ;)

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...
