java - Difference btn mContext.get().getApplicationContext() and getActivity() -

why in fragment getactivity() works mcontext.getapplicationcontext() not?

mdobpickerdialog = new datepickerdialog(getactivity(), new ondatesetlistener() {              public void ondateset(datepicker view, int year, int monthofyear, int dayofmonth) {                 calendar newdate = calendar.getinstance();                 newdate.set(year, monthofyear, dayofmonth);                 mdobedittext.settext(mdateformatter.format(newdate.gettime()));             }          },newcalendar.get(calendar.year), newcalendar.get(calendar.month), newcalendar.get(calendar.day_of_month));

my mcontext declared , initialized as:

private context mcontext;  public displayprofilefragment(context context) {         super();         mcontext = context;     }

getactivity() returns activity fragment associated with.

http://developer.android.com/reference/android/app/fragment.html#getactivity()

getapplicationcontext() returns global application context.

http://developer.android.com/reference/android/content/context.html#getapplicationcontext()

as why getapplicationcontext() doesn't work in code have provided, because shouldn't. creating dialog on current activity, need activity context, application context should used functions receivers, functions should destroyed when application destroyed, not when activity destroyed.

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
