how to select by value attribute

[Habib_7]

for example I have this html code:

    <select id="mySelect">
            <option value="0">apple</option>
            <option value="1">orange</option>
            <option value="2">banana</option>
            <option value="3">tomato</option>
        </select>

1-how can I select <option value="2">banana</option>
(by passing the value attribute to selector function)then click on it with javascript with out using jquery
2-Is there any way to select this just by passing apple to selector function with out passing the value?

Two ideas.

1. Change the value in the first to "apple".
2. Try no value. http://www.w3schools.com/tags/att_option_value.asp writes if you omit value what happens.
