鼠标指针碰到.replace(美元/ ^ \ s + | \ s + | (\ s) + / g, 1美元)应该做的诀窍!

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>

使用nodepad++函数,下面的regex对我来说很好,
发现:{1}\ \ s + K 替换:留空
还有一种可能:
str.replace( /\s+/g, ' ' )
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, " ");
