javascript - Web Storage API Session Storage: delete all keys like XYZ -


given following html session data:

hassession                            1 user                                  user_abc costtoserve599a8e8421a80              25 runningtotal                          100 maintenance599a8e8421a80              5 businessenhancements599a8e8421a80     25 businessenhancements599a8e8421a94     25 maintenance599a8e8421a94              10 frontierinvestments599a8e8421a94      5 costtoserve599a8e8421a86              0 frontierinvestments599a8e8421a86      5

i'm attempting delete keys contain:

599a8e8421a94

is there way like/wild card type delete on session storage?

loop through sessionstorage object , check if key contains 599a8e8421a94, if does, remove it:

for (var key in sessionstorage) {     if (key.indexof('599a8e8421a94') !== -1)         sessionstorage.removeitem(key); }

an example of in action:

/**  define dummy data... **/ var obj = {     'no-clean': 'i not cleaned.',     'testing599a8e8421a94': 25,     'another_test599a8e8421a94': 'e,ndleknfew',     '599a8e8421a94somemoretesting': '2knmsdkgsdg' };  /** loop through our dummy data , add sessionstorage. **/ (var key in obj) {     sessionstorage.setitem(key, obj[key]); }  /** part need, loop through sessionstorage object. **/ (var key in sessionstorage) {     /** check if key contains search string... **/     if (key.indexof('599a8e8421a94') !== -1)         sessionstorage.removeitem(key) }  console.log(sessionstorage)

jsfiddle - open console see remaining key/value in sessionstorage object.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
