如何在键入列表时按过滤器中的空间过滤？

Question

I want to filter a list by typing a space (just like any other character).

The current code is:

var search = $.trim($(this).val().replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&"));

If I have vege tables in my list and I type a space, or letter e and space, or space and letter t , the list should filter to show vege tables .

I have tried to add \\s to the code but it is not working as I had hoped:

var search = $.trim($(this).val().replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|\s]/g, "\\$&"));

Am I missing something?

Here's an example of how to filter a list of stings based on a pattern.

function filter(list, pattern) {
  return list.filter(function(item) {
    return pattern.test(item);
  });
}
const list = ['vege tables', 'man eater', 'word'];
console.log('Current list: ', list);

var pattern = ' e';
console.log('Filter by: "' + pattern + '"');

pattern = new RegExp(pattern, 'gi'); // convert the pattern to regex
console.log(filter(list, pattern)); // get filtered list, ['man eater']
