How to capitalize first and third letter?

Issue

I want to capitalize first letter and third letter in my textarea.

I can capitalize only first letter and then every next letters and words are transformed to lowercase.

If there is any solution for this problem, please tell me.

I am using AngularJS.

This is what im trying and did.

  link: function (scope, iElement, iAttrs, controller) {
        //console.log('init');

         controller.$parsers.push(function (inputValue) {
          var transformedInput = (!!inputValue) ? inputValue.charAt(0).toUpperCase()  + inputValue.substr(1).toLowerCase() : '';
                      if (transformedInput != inputValue) {
            controller.$setViewValue(transformedInput);
            controller.$render();
        }

        return transformedInput;
    });

This works only for first letter, it transforms to uppercase and then transforms another letter and words to lowercase.

I tried to change my code into this but nothing.

  var transformedInput = (!!inputValue) ? inputValue.charAt(0).toUpperCase()  + inputValue.substr(1).toLowerCase()  + inputValue.charAt(3).toUpperCase() + inputValue.substr(4).toLowerCase(): '';

Solution

Have a look at this. Same as what you are doing just using for loop to identify the character index to modify.

var inputValue = "test";

var transformedInput = '';

if(inputValue){
    for(var i=0; i<inputValue.length; i++){
  	if(i===0 || i=== 2){
	    transformedInput += inputValue.charAt(i).toUpperCase();
        } else {
    	    transformedInput += inputValue.charAt(i).toLowerCase();
    }
  }
}

console.log(transformedInput);
