javascript - Disabling or enabling a button depending on checkboxes oracle apex -


i have report checkboxes in each row , 1 submit button. want disable button when checkboxes unchecked. button should enabled when @ least 1 checkbox checked on report. tried creating dynamic action of type enable/disable. when no checkboxes checked button disabled when there @ least 1 check, button still disabled. tried javascript to couldnt accomplish because of poor js knowledge. codes tried below:

$("input[type='submit']").prop('disabled',true); if ( $(this.triggeringelement).is(':checked') )     $("input[type='submit']").prop('disabled',true);

///

if ($('input[type='checkbox']:checked').length > 0 && $("input[type='submit']").is(':disabled')) {     $("input[type='submit']").removeattr('disabled') } else if ($('input[type='checkbox']:checked').length == 0) {     $("input[type='submit']").attr('disabled', true) }

query of report:

select  apex_item.checkbox2(1,urun.barkod, 'class=indcheck') "select", u.ad, ma.ad magaza_adi, fiyat, apex_item.select_list(         p_idx           =>   2,         p_list_values   =>   '1;1,2;2,3;3,4;4,5;5,6;6,7;7,8;8,9;9,10;10',         p_show_null     =>   'yes',         p_null_value    =>   null,         p_null_text     =>   '-0-',         p_item_id       =>   'indselect') "adet" urunsatis urun, uye un, adres ad, anlasmalar an, magaza ma, urun u un.username = :session_user_name , un.id = ad.uye_id , ad.apartman_id = an.apartman_id , an.magaza_id = urun.magaza_id , ma.id = urun.magaza_id , u.barkod=urun.barkod order 1;

you need static id button better identify using javascript - example button1.

now, create dynamic action.

event: change

selection type: jquery selector

jquery selector: input.indcheck

this trigger dymanic action whenever 1 of checkboxes clicked. action of dynamic action, choose execute javascript code , use following code:

if ($(".indcheck:checked").length == 0) {     $("#button1").addclass("apex_disabled"); } else {     $("#button1").removeclass("apex_disabled"); }

this count checked checkboxes. in case amount zero, deactivate button. if amount @ least one, activate button. careful static id of button, needs match.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
