【问题描述】:

所以,我之前已经多次编写了这段代码的副本,它工作得很好,但现在它只是不想显示我的变量!我已经查看了我工作的 html 代码中的每一个小东西,并将所需的东西复制到我的新文件中,但它就是不想工作...... “str”和“score”应该在左上角显示为“Loading... 0”,但不,什么都没有... 代码如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Loading...</title>
	<style>
		body{
			font-size:20px;
			margin:0;
			overflow:hidden;
		}
		#str{
			display:block;
			font-size:30px;
			position: fixed;
			top: 1.0em;
			left: 1.0em;
			user-select: none;
			-moz-user-select: none;
			-khtml-user-select: none;
			-webkit-user-select: none;
			-o-user-select: none;
		}
		#str:hover{
			text-decoration: underline;
			cursor: pointer;
		}
		#score{
			display:block;
			font-size:30px;
			position: fixed;
			top: 2.0em;
			left: 1.0em;
			user-select: none;
			-moz-user-select: none;
			-khtml-user-select: none;
			-webkit-user-select: none;
			-o-user-select: none;
		}
		#score:hover{
			cursor: default;
		}
		#blackBox{
			background-color:black;
			display:block;
			position:fixed;
			width:0.1%;
			bottom:4.0em;
			left:0.0em;
			padding:0.5em 0em;
			text-align:left;
			vertical-align:top;
			border:2px solid black;
		}
		#blackBox2{
			display:block;
			position:fixed;
			width:99.5%;
			bottom:4.0em;
			left:0.0em;
			padding:0.5em 0em;
			text-align:left;
			vertical-align:top;
			border:2px solid black;
		}
	</style>
	<script type="text/javascript">

	  var _gaq = _gaq || [];
	  _gaq.push(['_setAccount', 'UA-33914917-1']);
	  _gaq.push(['_setDomainName', 'dhmholley.co.uk']);
	  _gaq.push(['_trackPageview']);

	  (function() {
		var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
		ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
		var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
	  })();

	</script>
</head>
<body onload="initialise()">

<div id="blackBox"></div>
<div id="blackBox2"></div>

<script>
var prc = 0,
	W = 1,

function initialise(){
	createInterface();
	updateScore();
}

function mload(){
  	prc = prc + 1;
  	W = prc / 100;
  	document.getElementById("blackBox").style.width = W + "%";
  	updateScore();
}

function createInterface(){
	var score = document.createElement('div');
	score.id = 'score';
	score.innerHTML = prc;
	document.body.appendChild(score);

	var str = document.createElement('div');
	str.id = 'str';
	str.innerHTML = 'Loading...';
	str.onclick = function(){
		mload();
	}
	document.body.appendChild(str);
}

function updateScore(){
	document.getElementById('score').innerHTML = prc;
}

</script>

</body>
</html>

【问题讨论】:

  • 你检查控制台了吗?它就在你身边
  • var prc=0,w=1,function 是语法错误
  • "Uncaught SyntaxError: Unexpected token function"
  • @Jonasw Omg,谢谢兄弟!我不敢相信那是事情。困扰我的事情是我的工作代码是这样写的,没有问题......奇怪
  • 添加为答案

【解决方案1】:

您可以使用一个 var 语句声明多个变量,但您必须使用 ; 关闭每个命令!它可以离开它,但我不会(那里有很好的例子:

//not good but should work:
var a,b
function c(){}

//the best solution:
var a,b;
function c(){};

//what you did
var a,b,function c(){};
//wich is invalid
