删除 phpgrid (phpgrid.org) 的行后，我需要刷新 Sub Total div/文本框值。
删除前:
删除第二行后:
<div id="sub_total_div">
<input name="txtSubTotal" type="text" id="txtSubTotal" size="15" value="<?php
$sql=mysqli_query($connection,'select sum(amount) from sales_temp');
$row = mysqli_fetch_array($sql);
echo $row[0];
?>"/>
</div>
请帮助我。
编辑后的代码:
function submitdata() {
var listItemName = document.getElementById("listItemName").value;
var listStock = document.getElementById("listStock").value;
var txtUnitPrice = document.getElementById("txtUnitPrice").value;
var txtQuantity = document.getElementById("txtQuantity").value;
var listCustomer = document.getElementById("listCustomer").value;
var txtReceiptNo = document.getElementById("txtReceiptNo").value;
var TheDate = document.getElementById("TheDate").value;
// Returns successful data submission message when the entered information is stored in database.
var dataString = {listItemName:listItemName, listStock: listStock, txtUnitPrice: txtUnitPrice, txtQuantity: txtQuantity, listCustomer: listCustomer, txtReceiptNo: txtReceiptNo};
if (listItemName == '' || listStock == ''|| txtUnitPrice == ''|| txtQuantity == ''|| listCustomer == ''|| txtReceiptNo == ''|| TheDate == '') {
salesitemsAddFail();
}
else {
// AJAX code to submit form.
$.ajax({
type: "POST",
url: "/pms/includes/functions/sales_temp_functions.php",
data: dataString,
cache: false,
success: function(html) {
//reload the sales datagrid once add the item details to temporary table (sales_temp)
$('#list').trigger("reloadGrid",[{page:1}]);
//window.location.reload();
//refresh/update the sub total value when adding
$("#sub_total_div").load(location.href + " #sub_total_div");
}
});
}
}
最佳答案
创建一个新的 php 文件: 获取总计.php
$sql=mysqli_query($connection,'select sum(amount) from sales_temp');
$row = mysqli_fetch_array($sql);
echo $row[0];
你的 js 代码将是:
submitdata() {
var listItemName = document.getElementById("listItemName").value;
var listStock = document.getElementById("listStock").value;
var txtUnitPrice = document.getElementById("txtUnitPrice").value;
var txtQuantity = document.getElementById("txtQuantity").value;
var listCustomer = document.getElementById("listCustomer").value;
var txtReceiptNo = document.getElementById("txtReceiptNo").value;
var TheDate = document.getElementById("TheDate").value;
// Returns successful data submission message when the entered information is stored in database.
var dataString = {listItemName:listItemName, listStock: listStock, txtUnitPrice: txtUnitPrice, txtQuantity: txtQuantity, listCustomer: listCustomer, txtReceiptNo: txtReceiptNo};
if (listItemName == '' || listStock == ''|| txtUnitPrice == ''|| txtQuantity == ''|| listCustomer == ''|| txtReceiptNo == ''|| TheDate == '') {
salesitemsAddFail();
}
else {
// AJAX code to submit form.
$.ajax({
type: "POST",
url: "/pms/includes/functions/sales_temp_functions.php",
data: dataString,
cache: false,
success: function(html) {
//reload the sales datagrid once add the item details to temporary table (sales_temp)
$('#list').trigger("reloadGrid",[{page:1}]);
//Ajax call to get the sub
$("#sub_total_div").load("gettotal.php");
}
});
}
}
注意:这不是正确的方法，但在您的情况下这会起作用
