I have this HTML code: <span id="search"> <input type="submit" value="" id="button"> </span> I want to change the opacity of #search::after when hovering #button #button:hover #search::after {opacity:1;} It wont work so I wonder if its even possible to do this. jNewbie Using only CSS It's impossible. What you can do is to use JavaScript/Jquery to trigger a action, like this: $("#button").hover( function() { $(this).parent().addClass("hover"); }); and in your css: #search.hover::after {opacity:1;} Related: Is there a CSS parent selector? This is not possible with just CSS. You might try using

What is the proper method to determine whether the root view (top level) controller of a navigation stack is appearing as a result of being initially presented vs. being uncovered? The iOS documentation suggests using isMovingToParentViewController inside viewWill/DidAppear: to make that determination. This works for view controllers pushed on the stack, but appears to always return FALSE for the stack root view controller. Thanks for helping. Chris Goldman Looks like someone else has answered the same question: iOS: isMovingToParentViewController is not working as expected . Though it is not

I'm very new to c and programming and need some help. In c on linux(cygwin) I am required to remove all child processes at exit. I have looked at the other similar questions but can't get it to work. I've tried- atexit(killzombies); //in parent process void killzombies(void) { printf("works"); kill(0, SIGTERM); printf("works"); if (waitpid(-1, SIGCHLD, WNOHANG) < 0) printf("works"); } for some reason, "works" doesn't even print ever. I press ctrl + c to exit. ALSO I have tried- prctl(PR_SET_PDEATHSIG, SIGHUP); //in child process signal(SIGHUP, killMe); void killMe() { printf("works"); exit(1);

Lets say that i have two entities public class EntityA { @id @GeneratedValue @Column(name="id") private Long id; @OneToMany(mappedBy="EntityA") @JoinColumn(name = "entityA_id") private List<EntityB> entityBList; } public class EntityB { @Column(name = "MODEL_PERCENT") private BigDecimal modelPercent; @ManyToOne @joincolumn(name="entityA_id") private EntityA entityA; } What i want now is, when i fetch the EntityA i want to add a where clause to fetch all EntityBs' whose modelPercent is greater than 0. I do not want to use filters since this requirement is only for this perticular situation. Eg

If possible, can I click on an element in an iframe and have that perform a function on the page it is rendered on? for example: <div class="page"> <iframe class="frame">[... the source will render: <div class="clickme"></div>...] </iframe> ...meanwhile, back on the main page... <script> $(".clickme").click(function(){ alert('clicked'); }); </script> </div> edit also, I forgot to mention that the iframe's src changes after the page loads, this could be an obstacle! It doesn't seem to work for me and I couldn't find an appropriate answer/question here. Thanks! If the user clicking on an item in

I have tried to use different methods suggested in StackOverflow but I cannot make the following work. I have a nested ChildComponent into a ParentComponent. Here the HTML of the parent: <div> ... <div> <span *ngIf="value" class="option-button cursor-pointer" [attr.modelURL]="value" (click)="$event.stopPropagation();getParts(assemblyLibrary)"> <i class="fa fa-cube"></i> </span> <child-component></child-component> Obviously, I have imported the child component into the parent one: import { SharedModule } from '../../shared'; //child declaration is inside here in the parent component, I am
