javascript - Disabling a checkbox until an iframe has scrolled -

i suspect not possible due browser security, have form @ end of iframe displaying our terms , conditions page. below checkbox agreeing these terms , conditions.

other sites have seen require scroll downwards in terms , conditions before checkbox active suspect done textarea or scrollable div rather iframe.

as such aware of how can spot when iframe has scrolled in javascript or jquery can enable checkbox 1 time has been scrolled.

following code in embedded document should it.

$(window).scroll(function () { if ($(document).height() <= $(window).height() + $(window).scrolltop()) $("#chk", window.parent.document).removeattr("disabled"); });

javascript jquery html

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison
