假设你还想覆盖制表符、换行符等,只需将\s\s+替换为' ':
string = string.replace(/\s\s+/g, ' ');
如果你真的只想覆盖空格(而不是制表符,换行符等),可以这样做:
string = string.replace(/ +/g, ' ');

我知道我迟到了,但我发现了一个很好的解决方案。
下面就是:
var myStr = myStr.replace(/[ ][ ]*/g, ' ');
更健壮的:
function trim(word) { word = word.replace(/[^\x21-\x7E]+/g, ' '); // change non-printing chars to spaces return word.replace(/^\s+|\s+$/g, ''); // remove leading/trailing spaces }
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, " ");
我建议
string = string.replace(/ +/g," ");
对于空格或
string = string.replace(/(\s)+/g,"$1");
还可以将多个退货转换为单个退货。
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
