Replaceing ampersands

[JSbeginner]

Hello,

I'm new to javascript and need a hand.

I have a form with an input field and text area, that I need to replace any input '&' with the word 'and'.

How would I accomplish this with an "onblur" event.

Thank you

element={value: 'Lewis & Clark & John & James'};

element.value=e lement.value.re place(/ *& */g,' and ');
alert(element.v alue)
