我找不到错误

这是一个javascript代码

<!Doctype html>     
<html>     
<title>JavaScript Tutorial</title>     
<body>     
<script language = "javascript">     
var cleanCities = ["Cheyenne ","Santa Fe ","Tucson ","Great Falls ","Honolulu"];     
var cityToCheck = "Tucson";

if(cityToCheck === cleanCities[i]) {     
  alert("You are clean");     
} 
</script> 

</body> 

</html>


JavaScript教程
var CleanCity=[“夏延”、“圣达菲”、“图森”、“大瀑布”、“檀香山”]；
var cityToCheck=“图森”；
如果（cityToCheck==清洁城市[i]）{
警惕（“你是干净的”）；
}

它说在第14行有一些问题，你的for循环在哪里，你是索引i？如果故意删除，则阵列中的Tucson最后有一个空间。使用修剪方法

另外language=“javascript”是错误的，它的类型通常为=“text/javascript”

代码应如下所示：

<!Doctype html> 
<html> 
<title>JavaScript Tutorial</title> 
<body> 
<script language = "javascript"> 
var cleanCities = ["Cheyenne ","Santa Fe ","Tucson ","Great Falls ","Honolulu"]; 
var cityToCheck = "Tucson"; 
if(cityToCheck === cleanCities[i]) { 
  alert("You are clean"); 
} 
</script> 
</body> 
</html>

在此处输入代码
var CleanCity=[“夏延”、“圣达菲”、“图森”、“大瀑布”、“檀香山”]；
var cityToCheck=“图森”；
对于（var i=0；我首先学习如何使用循环。
enter code here
var cleanCities = ["Cheyenne ","Santa Fe ","Tucson ","Great Falls ","Honolulu"];
var cityToCheck = "Tucson";
for(var i=0; i<cleanCities.length; i++) {
   if(cityToCheck === cleanCities[i].trim()){
    alert('you are clean');
   }
 }
