javascript - jQuery popup resize on phone -


i have small problem popup image displaying on mobile browser. popup displayed on mouse click , resize function sets size according viewport size.

this works fine , centred in viewport when opened, when tilt phone landscape call resize function doesn't seem work newly resized image off centre in viewport, repeated when phone returned portrait mode. have tested code on android chrome browser.

the resize function have used follows:

$(window).resize(function () {     $(".dialogcontent").css({         position: 'absolute',         left: ($(window).width() - $(".dialogcontent").outerwidth()) / 2,         top: ($(window).height() - $(".dialogcontent").outerheight()) / 2     }); });

sorry posting answer still can't comment yet.

based on have said little confused mouse click portion of code. surly resize function not being called when user clicks button first time. sure working way want @ all?

to answer question limited amount of understanding of code looks like

it should like:

 $(".dialogcontent").css({     position: 'absolute',     left: '50%',     'margin-left': $(".dialogcontent").outerwidth() / 2,     'margin-top': $(".dialogcontent").outerheight() / 2,     top: '50%' });

from understanding centre align positioned absolute set it's top , left 50% , offset positioned absolute element half.

now i'm home can make fiddle here

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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