我正在尝试使用php带来一些记录并进行一些计算。我现在正在做的是，每一行都有不同货币的下拉列表。当我选择每种货币时，它会计算并显示某些值。直到这里工作正常。
我想要实现的是，如果我选择第一个货币下拉列表，它应该计算完整的记录计算，而不是选择每行的货币。我想我需要在计算行的jquery中做一些循环。
小提琴你可以看到代码，但没有正确获得输出。所以我只是将代码放在服务器中。链接是http://spreadon.net/quot.html
以下是货币下拉列表的jquery脚本的一部分。
$(window).load(function() {
$(document).ready(function() {
$("select").on('change', function() {
var dept_number = $(this).val();
var price = $(this).find(':selected').data('price');
var selected = $(this).find('option:selected').text();
if (selected == "INR") {
$(this).closest('table').find('.total1').val($(this).closest('table').find('.total').val());
} else {
$(this).closest('table').find('.total1').val((($(this).closest('table').find('.total').val() * price) / $(this).closest('table').find('.inrvalue').val()).toFixed(3));
}
$(this).closest('table').find('.price_unit').val(($(this).closest('table').find('.total1').val() / $(this).closest('table').find('.qty').val()).toFixed(3));
});
});
});

我添加了工作代码，它将指导您如何迭代tr和它更改选择
查看它会给你提示的代码。
并且你在每种方法中都有这种力量，因此你可以实现自己的目标。
$(document).ready(function() {
$("select").on('change', function() {
var dept_number = $(this).val();
var price = $(this).find(':selected').data('price');
var selected = $(this).find('option:selected').text();
if (selected == "INR") {
$(this).closest('table').find('.total1').val($(this).closest('table').find('.total').val());
} else {
$(this).closest('table').find('.total1').val((($(this).closest('table').find('.total').val() * price) / $(this).closest('table').find('.inrvalue').val()).toFixed(3));
}
$(this).closest('table').find('.price_unit').val(($(this).closest('table').find('.total1').val() / $(this).closest('table').find('.qty').val()).toFixed(3));
// this is upto your logic.
//now i have write my code which will ittrate through each row and column
$(".trToiitrate").each(function(e) {
alert("it is from tr");
$(this).find("td").each(function(e) {
alert("this is from td");
});
});
});
