javascript - collapse spread not disappear after dialog hidden -


i made modal dialog css:visibility hidden , visible.

<div id="mymodal">   <a data-toggle="collapse" href = "#spread">     <span class = "caret"></span>spread   </a>   <div id = "spread" class = "panel-collapse collapse">    ...   </div> </div> <button onclick = "hidemodal()">hide modal</button>

javascript code

hidemodal(){ var modal = document.getelementbyid("mymodal"); modal.style.visibility = "hidden"; }

all things working menu collapse not working well. if open menu , hide dialog things disappear spread not disappear.
there have met kind of issue?

your problem in line

modal.style.visibility = "hidden";

in experiment question, visibility collapse override visibility hidden.

solution change hidemodal() content to

$('#mymodal').addclass("hidden");

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ...
