I am looking for a regular expression that will eliminate any leading white space while still permitting spaces between words

Below is the code I've created for an angularjs directive that removes spaces. It successfully eliminates spaces between words, but unfortunately still allows leading spaces.

function customValidation() {

   return {
     require: 'ngModel',
     link: function(scope, element, attrs, modelCtrl) {

       modelCtrl.$parsers.push(function (inputValue) {

         var transformedInput = inputValue.toLowerCase().replace(/ /g,''); 

         if (transformedInput!== inputValue) {
           modelCtrl.$setViewValue(transformedInput);
           modelCtrl.$render();
         }         

         return transformedInput;         
       });
     }
   };
}

Answer №1

To eliminate any extra spaces specifically from the start

valueToTransform.toLowerCase().replace(/^\s+/, '').replace(/\s+/g, ' ');
