javascript - Preventing default behavior for tab stops listeners from working -


i trying dynamically create input field , implement tab autocomplete feature. unfortunately, whenever listen tab , call preventdefault on keydown event stop tab focusing on other fields, keypress listener cannot register tab.

var element = document.createelement("input");   //assign different attributes element. element.setattribute("type", "text"); element.setattribute("value", ""); element.setattribute("name", "test name"); element.setattribute("spellcheck", "false"); element.setattribute("style", "width:400px"); element.classlist.add('text');   element.onkeydown = function(e) {     if(e.keycode == 9){         e.preventdefault();     } }  element.onkeypress = function(e) {     if (!e) e = window.event;     var keycode = e.keycode || e.which;     if (keycode == 13){         // code     } else if(keycode == 9) {         console.log("detected"); //never printed console     }   }

how can stop tab doing default behavior while adding own functionality?

keypress gets fired after keydown, , since prevent default behaviour in keydown, think prevents keypress event being fired. should try putting in same event handler, or handlers on same event, might tricky, since nothing guarantees order in gets executed.

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 ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
