javascript - jQuery check if element has a class -

-

i trying check see if html element has class , if so, run function jquery. code works if element doesn't have multiple classes. believe need use .hasclass() method, couldn't figure out.

var pageclass = $("body").attr('class'); switch (pageclass) {   case ("page1"):     $('h1').html('heading1');     break;   case ("page2"):      $('h1').html('heading2');     break;   default:     $('h1').html('default'); }

fiddle: https://jsfiddle.net/9o70dbzz/2/

this can solved selectors:

$('h1').html('default'); $('body.page1 h1').html('heading1'); $('body.page2 h1').html('heading2');

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...
