Question

I have modified a function to meet my need. This is what I have written to restrict multiple repetition of dots:

$('#title').val(){
    replace(/\.{2,}/g, '.');
});

Is it correct? How can I make this in function so I can call with every element of the form?

1. Here is your code turned into a jQuery function/plugin.

jQuery.fn.singleDotHyphen = function(){
    return this.each(function(){
        var $this = $(this);
        $this.val(function(){
            return $this.val()
                .replace(/\.{2,}/g, '.')
                .replace(/-{2,}/g, '-');    
        });
    });
}

2. Here is how you use it

$('selector').singleDotHyphen();
