我试图弄清楚如何根据使用 javascript 在另一个输入字段中输入的内容自动填充输入值。这是我的代码:
<script>
add = document.getElementById('address').value;
city = document.getElementById('city').value;
state = document.getElementById('state').value;
zip = document.getElementById('zip').value;
compAdd = add+" "+city+" "+state+" "+zip;
function showAdd(){
document.getElementById('shipadd1').value=compAdd;
document.getElementById('add1').innerHTML=compAdd;
}
</script>
<form action="" onchange="showAdd();">
Home Address: <input id="address" name="address" type="text" /><br/>
Apt or Suite Number: <input id="suite" name="suite" type="text" /><br/>
City/Town: <input id="city" name="city" type="text" /><br/>
State:<select id="state" name="state" value="">...</select><br/>
Zip:<input id="zip" name="zip" type="text" value=""/><br/>
<p> Select Shipping Address Below: </p>
<input type="checkbox" id="shipping-address-1" name="address1" value=""><span id="shiadd1">(Print auto-populated shipping address here...)</span>
<input type="checkbox" id="shipping-address-2" name="address2" value="">ABC Corp 123 Main Street, My City, State Zip
</form>
