javascript - Find similar items in an object -


i have object looks so:

{     title: "test",     subtitle: "test",     "list-item-1": "this item 1",     "list-item-2": "this item 2",     "list-item-3": "this item 3" }

i want find keys in object end -1, or -numerical value. , group of in way can access them calling "if item has -1 @ end of it, find other items have same first part (list-item in case) , save them own array or variable.

how go this?

one simple way harvest properties use built in methods keys(), filter(), , test():

var obj={     title: "test",     subtitle: "test",     "list-item-1": "this item 1",     "list-item-2": "this item 2",     "list-item-3": "this item 3", };  var arrok=object.keys(obj).filter(/./.test, /list-item-\d+$/); alert(arrok); // shows: "list-item-1,list-item-2,list-item-3"

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
