javascript - How do I clear a form and reset a drop down menu to the first option? -


i have form has text fields, drop down menu, radio buttons, , check boxes. able clear of input entered user need modify form when user clicks "clear entries" of above fields cleared , drop down menu return default state of "pa".

function doclear() { document.pizzaform.customer.value = ""; document.pizzaform.address.value = ""; document.pizzaform.city.value = ""; document.pizzaform.state.value = ""; document.pizzaform.zip.value = ""; document.pizzaform.phone.value = ""; document.pizzaform.email.value = "";  document.pizzaform.sizes[0].checked = false; document.pizzaform.sizes[1].checked = false; document.pizzaform.sizes[2].checked = false; document.pizzaform.sizes[3].checked = false;  document.pizzaform.toppings[0].checked = false; document.pizzaform.toppings[1].checked = false; document.pizzaform.toppings[2].checked = false; document.pizzaform.toppings[3].checked = false; document.pizzaform.toppings[4].checked = false; document.pizzaform.toppings[5].checked = false; document.pizzaform.toppings[6].checked = false; document.pizzaform.toppings[7].checked = false; document.pizzaform.toppings[8].checked = false; return;  }

this html form looks like:

 <form>   <font size="3">state:</font>   <select name="state">     <option selected>pa</option>     <option value="nj">nj</option>     <option value="ny">ny</option>     <option value="de">de</option>   </select> </form>

i have pa selected suggestion however, not select pa when clear entries button clicked.

update html pa option has value

<option selected value="pa">pa</option>

add following js:

var elements = document.getelementsbytagname('select'); elements[0].value = 'pa';

a better way select set id on it

html 

 <select name="state" id="myselect">

js

document.getelementbyid('myselect'); element.value = 'pa';

this prevent issues have if added select, (unless added select same id invalid html anyways)
