实时计算(2)？
实时计算(2)？
提问于 2015-08-19 19:19:28
我最近发了一个问题here
答案做得很好，但是现在我尝试在我的代码中添加一些东西，它不起作用，我已经做了所有可能的调试，但它只是不能显示总数！这是我的HTML
<label for ="FIELD7">Would you like Weapons?: </label>
<label for="FIELD7">Yes</label>
<input type="radio" id="weaponyes" name="FIELD7" value="Yes" onclick="doMath()" checked data-clicked="no" />
<label for="FIELD7">No</label>
<input type="radio" id ="weaponno" name="FIELD7" value="No" />这是我的jQuery
function doMath() {
var basePrice = 15;
var baseModel = 0;
var customModel = 5;
var modelTotal;
if (document.querySelector('input[name="FIELD6"]:checked').value == "Normal Model") {
modelTotal = basePrice;
}
if (document.querySelector('input[name="FIELD6"]:checked').value == "Workshop Model") {
modelTotal = customModel;
}
var weaponTotal;
var weapons = 5;
if(document.querySelector('input[name="FIELD7"]:checked').value == "Yes") {
weaponTotal = weapons;
}
else(document.querySelector('input[name="FIELD7"]:checked').value == "No") {
weaponTotal = 0;
}
var totalPrice = modelTotal + weaponTotal;
console.log(totalPrice);
document.getElementById('total').innerHTML = '<span style="color:black">Total Price:' + totalPrice + '</span>';
}
</script>我已经知道了模型的部分，我只需要帮助"var weaponTotal;“从哪里开始。它不再显示价格了：

你有语法错误。
使用"else if“而不是"else”
else if(document.querySelector('input[name="FIELD7"]:checked').value == "No")联署材料：
function doMath() {
var basePrice = 15;
var baseModel = 0;
var customModel = 5;
var modelTotal;
if (document.querySelector('input[name="FIELD6"]:checked').value == "Normal Model") {
modelTotal = basePrice;
}
if (document.querySelector('input[name="FIELD6"]:checked').value == "Workshop Model") {
modelTotal = customModel;
}
var weaponTotal;
var weapons = 5;
if(document.querySelector('input[name="FIELD7"]:checked').value == "Yes") {
weaponTotal = weapons;
}
else if(document.querySelector('input[name="FIELD7"]:checked').value == "No") {
weaponTotal = 0;
}
var totalPrice = modelTotal + weaponTotal;
console.log(totalPrice);
document.getElementById('total').innerHTML = '<span style="color:black">Total Price:' + totalPrice + '</span>';
