您好,我在获取复选框数值时遇到了问题。为了完成一个学校项目,我制作了一个披萨订购表格,现在需要打印订单汇总,但是无法正确打印配料信息。
<label><input type = "checkbox" name = "topping" id = "sausage" value = "Sausage"/> Sausage</label>
<label><input type = "checkbox" name = "topping" id = "pepperoni" value = "Pepperoni"/> Pepperoni</label>
<label><input type = "checkbox" name = "topping" id = "beef" value = "Beef"/> Beef</label>
<label><input type = "checkbox" name = "topping" id = "bacon" value = "Bacon"/> Bacon</label><br />
<label><input type = "checkbox" name = "topping" id = "chicken" value = "Chicken"/> Chicken</label>
<label><input type = "checkbox" name = "topping" id = "ham" value = "Ham"/> Ham</label>
<label><input type = "checkbox" name = "topping" id = "olives" value = "Olives"/> Olives</label>
<label><input type = "checkbox" name = "topping" id = "peppers" value = "Peppers"/> Peppers</label><br />
<label><input type = "checkbox" name = "topping" id = "tomatoes" value = "Tomatoes"/> Tomatoes</label>
<label><input type = "checkbox" name = "topping" id = "mushrooms" value = "Mushrooms"/> Mushrooms</label>
<label><input type = "checkbox" name = "topping" id = "pineapple" value = "Pineapple"/> Pineapple</label>
这是HTML的一部分,我认为问题出在我的JavaScript函数上。
function toppings(inputCollection) {
var toppings = "";
for (var i = 0; i < inputCollection.length; i++) {
if (inputCollection[i].checked) {
toppings = toppings + inputCollection[i].value + " ";
}
}
return toppings;
}
我对JavaScript还比较新,所以如果我犯了一个愚蠢的错误,请不要批评我。非常感谢。
