删除字符串之间的短划线并在Javascript中大写字符串

Question

I am trying to capitalize the String after removing all dashes in between.

so this i-am-string would become I am string .

This is what I tried, but it does capitalize, but I don't know how to remove dashes and capitalize.

function tweakFunction (string) {

     return string.charAt(0).toUpperCase() + string.slice(1);
}

Thanks

Answer 1

You could use a couple regex, like in the PHP version you previously posted:

var result = str
  .replace(/-/g, ' ')
  .replace(/^./, function(x){return x.toUpperCase()})

Answer 2

function tweakFunction(str) {
   str = str.replace(/-/g, ' ');
   return str.charAt(0).toUpperCase() + str.slice(1);
}
console.log(tweakFunction('i-am-string')); //=> "I am string"

Answer 3

/* Capitalize the first letter of the string and the rest of it to be Lowercase */
function capitalize(word){
    return word.charAt(0).toUpperCase() + word.substring(1).toLowerCase()
}
console.log(capitalize("john")); //John
console.log(capitalize("BRAVO")); //Bravo
console.log(capitalize("BLAne")); //Blane
