Question

当我调用此函数＆＃34; showMe（calcTotal（myNumberArray））;＆＃34;它在控制台中有效，但在代码中调用时它不起作用。对不起，如果我的代码惹恼了你的眼睛，或者从那时起就没有。它应该计算总数。我想知道为什么浏览器没有看到调用或为什么值没有显示在屏幕上。

<!DOCTYPE html>
<html>
<head>
	<title></title>
	<style>

</head>
<body>
<button id="hit">hit</button>
  <div id="number"></div>
  <div id="arrayOutput"></div>
  <div id="someId"></div>
  <div id="out2"></div>
<script>
	//Services helper functon
	 var myNumberArray = [];

document.getElementById('hit').onclick = function randomNumber() {
	var card = Math.floor(Math.random() * 10) + 1;
 document.getElementById('number').innerHTML=card;
myNumberArray.push(card);
var number =myNumberArray.value;
  var arrayOutput = document.getElementById('number');
var someId = document.getElementById('someId');
someId.innerHTML = myNumberArray;

  };
//var output = myNumberArray = calcTotal(list);
function calcTotal(myNumberArray) {
	var total = 0;
	for(var i = 0; i < myNumberArray.length; i++){
		total += myNumberArray[i];
	}
	return total;
	

}
//document.getElementById('out2').innerHTML = out2;
   what = calcTotal(myNumberArray);
var what= calcTotal(myNumberArray);

function showMe(VAL) {
	var parent = document.getElementById('out2');
	parent.innerHTML = VAL;
}
showMe(calcTotal(myNumberArray));


</script>

如果您想要点击按钮更新总值，则需要在点击处理程序中调用showMe(calcTotal(myNumberArray));。

＆＃13;

//Services helper functon
var myNumberArray = [];

document.getElementById('hit').onclick = function randomNumber() {
  var card = Math.floor(Math.random() * 10) + 1;
  document.getElementById('number').innerHTML = card;
  myNumberArray.push(card);
  var number = myNumberArray.value;
  var arrayOutput = document.getElementById('number');
  var someId = document.getElementById('someId');
  someId.innerHTML = myNumberArray;
  showMe(calcTotal(myNumberArray));

};
//var output = myNumberArray = calcTotal(list);
function calcTotal(myNumberArray) {
  var total = 0;
  for (var i = 0; i < myNumberArray.length; i++) {
    total += myNumberArray[i];
  }
  return total;


}
//document.getElementById('out2').innerHTML = out2;
what = calcTotal(myNumberArray);
var what = calcTotal(myNumberArray);

function showMe(VAL) {
  var parent = document.getElementById('out2');
  parent.innerHTML = VAL;
}

showMe(calcTotal(myNumberArray));

<button id="hit">hit</button>
<div id="number"></div>
<div id="arrayOutput"></div>
<div id="someId"></div>
<div id="out2"></div>
