当前回答
var string = "The dog has a long tail, and it is RED!";
var replaced = string.replace(/ +/g, " ");
或者如果你也想替换制表符:
var replaced = string.replace(/\s+/g, " ");
其他回答
let nameCorrection = function (str) {
let strPerfect = str.replace(/\s+/g, " ").trim();
let strSmall = strPerfect.toLowerCase();
let arrSmall = strSmall.split(" ");
let arrCapital = [];
for (let x of arrSmall.values()) {
arrCapital.push(x[0].toUpperCase() + x.slice(1));
}
let result = arrCapital.join(" ");
console.log(result);
};
nameCorrection("Pradeep kumar dHital");

以下是对我来说很有效的解决方案:
var text = “ Tes ddas dMd WAlkman 3Dsfd ” .toLowerCase() .replace(/\b\s+/g, “ ”) .replace(/\b\w/g, s => s.toUpperCase()) .trimStart() .trimEnd(); 控制台.log(文本); 结果: Tes Ddas Dmd 随身听 3dsfd
Def removeblanks(text):返回re.sub(r'\s\s+'," ",text) 我正在处理一个有很多重复空格的大型文本数据。 上面的RE对我很有用。所有重复的空格都被一个空格取代。
尝试用一个空格替换多个空格。
<script type="text/javascript">
var myStr = "The dog has a long tail, and it is RED!";
alert(myStr); // Output 'The dog has a long tail, and it is RED!'
var newStr = myStr.replace(/ +/g, ' ');
alert(newStr); // Output 'The dog has a long tail, and it is RED!'
</script>
