Javascript：检查字符串定界符之间是否有空格

Question

I need to trim out or add a space to any word before or after any slash(/) located within the string.

var str = 'some/value    /even /more   /text';

// should ideally be equal to this 'some /value /even / more text'

I managed to get this to work using .split() and .join()

var text = $(this).val();
var arr = text.split('/');

for(var i=0, limit = arr.length; i < limit; i++) {
   arr[i] = $.trim(arr[i]);
}

arr.join(' / ');

but the I think this could be further optimized with regular expressions.

Answer 1

str = str.replace(/\s*\/\s*/g, ' / ');

Answer 2

Do you mean something like that?

var str = this.value.replace(/\s*\/\s*/g, " / ");

It can also be done with:

 var str = this.value.match(/[^ /]+/g).join(" / ");
