伙计们，我试图找出输入的句子中最长的word，但是代码未输出任何内容。 smb可以帮我吗？
<!DOCTYPE html>
<html>
<head lang = "en">
<meta charset = "UTF-8">
<title>LongestWord</title>
</head>
<body>
<script language = "Javascript" type = "text/javascript">
var sentence = prompt("Enter sentence: ");
var splitted = sentence.split("\\s+");
var longestWord = splitted[0];
for(var i = 0; i < splitted.length; i++){
for(var j = 0; j < splitted[i].length - 1; j++){
if(longestWord.length < splitted[i].length){
longestWord = splitted[i];
}
}
}
document.write("The longest word in the sentence is " + longestWord);
</script>
</body>
</html>
最佳答案
将您的正则表达式代码更改为：
var splitted = sentence.split(/\s+/);
编辑：下面是对该函数的稍有不同：
function longestWord(str) {
return str.split(/\s+/).sort(function(w1, w2) {return w2.length - w1.length;})[0];
}
var phrase = "dmitriy nesterkin drd";
console.log(longestWord(phrase));
