javascript - How to delegate `hover()` function by using `on()` -


this question has answer here:

i had coffee code this.

  $('.foo').hover \     (-> $(this).css "cursor", "pointer"), \     (-> $(this).css "cursor", "default")

and want apply function dynamically appended dom, tried delegate function using on() this.

as example referred this question

  $(document).on 'hover', '.foo', (event) ->     $(this).css "cursor", "pointer" if event.type "mouseover"     $(this).css "cursor", "default" if event.type "mouseout"

but code doesn't work @ all.

how can apply function dynamically added elements?

i think you'll need unbind , add hover handler. also, don't need line continuations if you're indenting (in case). 

$( ->     #debugger     addfoodiv = ->      div = $('<div class="foo">this foo div</div>')      $(this).parent().append(div)     addfoohandler()    onleavehandler = ->      $(this).css "cursor", "pointer"       $(this).css "background", "white"    onenterhandler = ->        $(this).css "cursor", "default"       $(this).css "background", "lightblue" # it's real obvious    $('.appendfoo').on('click', addfoodiv)    addfoohandler = ->        $(".foo").unbind("hover")      $(".foo").hover(onenterhandler, onleavehandler)    addfoohandler() )

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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 .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
