javascript - 删除标点符号前的空格javascript/jquery

Question

我想删除 Javascript/jquery 中每个标点符号前的空格。例如

Input string = " This 's a test string ."

Output = "This's a test string."

Answer 1

"This string has some -- perhaps too much -- punctuation that 's not properly "
+ "spaced ; what can I do to remove the excess spaces before it ?"
.replace(/\s+(\W)/g, "$1");

//=> "This string has some-- perhaps too much-- punctuation that's not properly "
//   + "spaced; what can I do to remove the excess spaces before it?"
