Question

我在订购表格时无法在线订购产品。我有不同类别的多种产品。例如家具和电力。在家具类别中，我有三个产品input type="number"，data-price属性，其中填写了价格（产品从数据库中取出），因此所有内容都将自动填写。

输入值的计算出了什么问题。我在下面有这个片段，它正好显示了这个问题。当您为第一个产品选择1时，它会正确显示25.50，但是当您将数量增加一个时，它的值为2.然后价格显示为76.50 ......这样就出错了。

有人可以帮我解决这个问题，以便计算出正确的金额吗？

提前致谢！

var furnitureTotal = 0;

$("#furnituretotal").html(furnitureTotal.toFixed(2));

function getFurnitureProductsTotal(className) {
	var furnitureProducts = $('.' + className);
					
	furnitureProducts.each(function() {
		var price = parseFloat($(this).attr('data-price'));
		var number = $(this).val();
		furnitureTotal += price * number;
	});
					
	$("#furnitureamount").val(furnitureTotal.toFixed(2));
	$("#furnituretotal").html(furnitureTotal.toFixed(2));
}

每次while True: driver.get(driver.getCurrentUrl()) WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "id_of_element_present_in_all_situation"))) source = driver.page_source -- check for change --函数运行时，您只需将furnitureTotal重置为0：

＆＃13;

getFurnitureProductsTotal

＆＃13;

var furnitureTotal = 0;

$("#furnituretotal").html(furnitureTotal.toFixed(2));

function getFurnitureProductsTotal(className) {
  var furnitureProducts = $('.' + className);
  furnitureTotal = 0;

  furnitureProducts.each(function() {
    var price = parseFloat($(this).attr('data-price'));
    var number = $(this).val();
    furnitureTotal += price * number;
  });

  $("#furnitureamount").val(furnitureTotal.toFixed(2));
  $("#furnituretotal").html(furnitureTotal.toFixed(2));
}
