"The dog has a long tail, and it is RED!"
什么样的jQuery或JavaScript魔法可以用来保持空间只有一个最大空间?

一种更健壮的方法:如果存在初始空格和尾随空格,则该方法也会删除它们。例如:
// NOTE the possible initial and trailing spaces
var str = " The dog has a long tail, and it is RED! "
str = str.replace(/^\s+|\s+$|\s+(?=\s)/g, "");
// str -> "The dog has a long tail, and it is RED !"
你的例子没有这些空格,但它们也是一个非常常见的场景,而公认的答案只是把它们精简成单个空格,比如:“the…红色!,这不是您通常需要的。
其他回答
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>

鼠标指针碰到.replace(美元/ ^ \ s + | \ s + | (\ s) + / g, 1美元)应该做的诀窍!
这个脚本删除了单词和修饰之间的任何空白(多个空格,制表符,返回值等):
// Trims & replaces any wihtespacing to single space between words
String.prototype.clearExtraSpace = function(){
var _trimLeft = /^\s+/,
_trimRight = /\s+$/,
_multiple = /\s+/g;
return this.replace(_trimLeft, '').replace(_trimRight, '').replace(_multiple, ' ');
};
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, ' ');
还有一种可能:
str.replace( /\s+/g, ' ' )
