Question

I want to do an ucwords() in JavaScript on a string of the form: test1_test2_test3 and it should return Test1_Test2_Test3.

I already found an ucwords function on SO, but it only takes space as new word delimiters. Here is the function:

function ucwords(str) {
return (str + '').replace(/^([a-z])|\s+([a-z])/g, function ($1) {
    return $1.toUpperCase();
});

Could anyone help?

Answer 1

Just add an underscore to the list of acceptable word breaks:

function ucwords(str) {
return (str + '').replace(/^([a-z])|[\s_]+([a-z])/g, function ($1) {
    return $1.toUpperCase();
})
};

As you can see ive replace the bit which was \s+ to [\s_]+
