arrays - Is it possible to grab the NUMBER that was concatenated to a string? (Javascript) -

-

i'm using cookies , setting them this: 

document.cookie ="cookievalue1="+cookievalue1;  document.cookie ="cookievalue2="+cookievalue2; document.cookie ="cookievalue3="+cookievalue3;

then put in array called cookie array:

var allcookies = document.cookie; cookiearray = allcookies.split(';');

if print out array, like: cookievalue1= 23 or cookievalue2= 42.

but there way value after string (23 or 42 only) rather string , number?

i tried deleting "cookievalue=" part, makes can't store cookies. i'm using forms , want numbers inputted can use them , add/subtract them on page. right now, can't add or subtract anything.

you do:

allcookies.split(';').map(c => c.split('=')[1]);

it'd give cookie value string. if numbers can do:

allcookies.split(';').map(c => +c.split('=')[1]);

this gives cookie values numbers.

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...
