创建蛋糕订购表格,可用的蛋糕数量可能因月而异。我试图调整从@Anderson Contreira创建的JS函数,但在我的小提琴中它不起作用。以下是我到目前为止的情况 -
为什么输入数量时没有任何改变?

语法 的 JS
function calculate(el){
var quantity = el.val();
var id = el.attr("id").replace("item_","").replace("_qty","");
var data = {quantity: quantity,id:id};
var targetTax = $("#item_"+id+"_tax");
var targetTotalPrice = $("#item_"+id+"_totalprice");
$.post($.post(window.alert("It's been one or two or three entered");
});
}
var qty = $("#item_1_qty");
var qty1 = $("#item_2_qty");
var qty2 = $("#item_3_qty");
qty.on("keyup",function(){
window.alert("It's been one or two or three entered");
});

scope :without_children_at(date) = {
joins(:childs).where("DATE(created_at) != DATE(?)", date)
}
试试这个,你在文档实际加载之前分配变量。

看看这里:https://jsfiddle.net/andersoncontreira/mtu6syby/1/
您可以进行一些更改并且效果很好:
在项_ _ _ qty的每个输入中添加一个类,例如:<input type="text" id="item_1_qty" class="item_qty" />
在您的javascript中,您可以将通话保留为通用:
jQuery(document).ready(function(){
//you can use a class for help you
$(".item_qty").on("keyup",function(){
//window.alert("It's been one or two or three entered");
calculate($(this));
});
});
