HTML 입력을 12 개의 열로 나눕니다.

Question

angularjs에서 하나의 입력 필드 만 사용하여 이미지와 같은 입력 필드를 만들 수 있습니까? 각 상자에는 하나의 번호 만 허용됩니다.

<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 
<li><input type="text" maxlength="1" onkeypress="return isNumber(event,$(this))"></li> 

function isNumber(evt,ele) { 
evt = (evt) ? evt : window.event; 
var charCode = (evt.which) ? evt.which : evt.keyCode; 
if (charCode > 31 && (charCode < 48 || charCode > 57)) { 
    return false; 
} 
if(ele.val().length == 0){ 
    ele.parent().next().children('input').focus(); 
} 


    return true; 
} 

나는 열두 입력 상자를 사용했다. 그것을 할 수있는 다른 방법이 있습니까? 또한 jquery를 사용하지 않아야합니다.

Answer 1

아니요, 할 수 없습니다.

하지만 사용자의 백 스페이스/입력 편의성을 향상시켜 구현을 향상시킬 수 있습니다. 너무 여기

var wrapper = document.getElementById('myInputWrapper'); 
 

 
var numberOfInputs = 12; 
 
var inputList = []; 
 

 
for(var i=0; i<numberOfInputs; i++){ 
 
\t var input = document.createElement('input'); 
 
    input.type = "text"; 
 
    input.setAttribute('data-number', i+1); 
 
\t inputList.push(input); 
 
\t wrapper.appendChild(input); 
 
    input.addEventListener('keydown', function(e){ 
 
\t \t // If backspace 
 
\t \t if(isBackspace(e)){ 
 
    \t if(this.value.length == 0){ 
 
    \t \t var previus = parseInt(this.getAttribute('data-number')) - 2; 
 
     \t if(previus >= 0){ 
 
    \t \t inputList[previus].focus(); 
 
     \t } 
 
     } 
 
     return true; 
 
    }

편집 붙여 넣기 지원이 추가 여기

은 예입니다.
