jquery - Strip white spaces on input

Question

I have a field that does not need any white spaces. I need to remove any as they are entered. Here's what I'm trying... no luck so far

$('#noSpacesField').click(function() {
    $(this).val().replace(/ /g,'');
});

Answer 1

Use jQuery trim to remove leading and trailing white space

$.trim(" test case "); // 'test case'

To remove all whitespace...

" test   ing  ".replace(/s+/g, ''); // 'testing'

To remove whitespace as it is entered...

$(function(){
  $('#noSpacesField').bind('input', function(){
    $(this).val(function(_, v){
      return v.replace(/s+/g, '');
    });
  });
});
