[英]Form Calculator Script Base Price Not Loading OnLoad
I have a calulcator in my form to calculate my dropdown options choices.我的表单中有一个计算器来计算我的下拉选项选择。
$(function() {
$("select.calculate").on("change", calc);
$("input[type=checkbox].calculate").on("click", calc);
function calc() {
var basePrice = 60;
newPrice = basePrice;
$("select.calculate option:selected, input[type=checkbox].calculate:checked").each(function() {
newPrice += parseInt($(this).data('price'), 10);
});
newPrice = newPrice.toFixed(2);
$("#item-price").html(newPrice);
$("#item_price_val").val(newPrice);
}
});
and in html to get the number out I have it as:并在 html 中获取数字,我将其设为:
<span id="item-price">0</span>
problem is, i have the baseprice at 60, however when i get on the page, its zero.问题是,我的基本价格是 60,但是当我进入页面时,它是零。 only when i make selections will the price go up.只有当我做出选择时,价格才会上涨。 how do i get the baseprice to appear from the beginning at page load?我如何在页面加载时从一开始就显示基本价格?
I need it to start as base price as those selections are not required, so if I do not choose those, i will click submit form, and it submits zero dollars instead of 60 dollars.我需要它作为基本价格开始,因为这些选择不是必需的,所以如果我不选择那些,我将点击提交表单,它提交零美元而不是 60 美元。
var basePrice = 60;
$(document).ready(function() {
$("select.calculate").on("change", calc);
$("input[type=checkbox].calculate").on("click", calc);
$("#item-price").html(basePrice);
$("#item_price_val").val(basePrice);
});
function calc() {
newPrice = basePrice;
$("select.calculate option:selected,input[type=checkbox].calculate:checked").each(function() {
newPrice += parseInt($(this).data('price'), 10);
});
newPrice = newPrice.toFixed(2);
$("#item-price").html(newPrice);
$("#item_price_val").val(newPrice);
}
