我有一个字符串,我需要修正它 以便把它附在查询中。
说我有"每逢不时的篮子"的字符串 我希望它成为"每个机会的篮子"
我需要找到一个空格, 并用连字符替换它。 然后, 我需要检查字符串中是否有另一个空格 。 如果没有, 请返回固定的字符串 。 如果没有, 请再次运行相同的进程 。
对我来说,这听起来像一个循环函数,但我不知道如何设置它。如果有任何帮助,我非常感激。

您可以使用这样的正则替换 :
var str = "A Basket For Every Occasion";
str = str.replace(/s/g, "-");
Regex 中的“ g” 旗将使得所有空间都更换。
您可能想要将多个空格折成一个连字符, 这样您就不会在一行中出现多个破折号。 这样看起来 :
var str = "A Basket For Every Occasion";
str = str.replace(/s+/g, "-");
全球白空间
(g) 的替换和查找
var a = "asd asd sad".replace(/s/g,"-");
a 成为
"asd-asd-sad"
尝试
value = value.split( ).join( - );
我用这个来消除我的空格。 而不是用连字符, 我让它空了, 效果很好 。 也是JS. < code>.split( liter) code > 将删除限制符, 并将字符串放入一个阵列( 没有限制元素 ), 这样您就可以用连字符加入数组 。
