我已经搜索并搜索了所有我发现的jQuery问题和解决方法。我有一个脚本设置工作正常，但这个不会发布3个值到PHP脚本。我甚至试图强制将3个设置值放入我正在放置时间戳的位置，但这不起作用。我有点失落。
此脚本生成不同的字段/输入以运行updateCoupon（）
function updateForm(formNum,id){
var str = 'edit-contents'+id;
switch( formNum )
{
case 1:
document.getElementById(str).innerHTML = "<div class='title-input'>Promo Title:<br><input type='text' size='25' maxlength='100' id='ptitle' name='ptitle'><input name='Edit' type='button' class='EditCoup' id='EditCoup' value='Edit' onClick='javascript:updateCoupon("+id+",1);'></div>";
break;
case 2:
document.getElementById(str).innerHTML = "<div class='description-input'>Promo Description:<br><textarea maxlength='1256' cols='40' rows='5' id='pdescription' placeholder='Use <br> to insert a line break' name='pdescription'></textarea><input name='Edit' type='button' class='EditCoup' id='EditCoup' value='Edit' onClick='javascript:updateCoupon("+id+",2);'></div>";
break;
case 3:
document.getElementById(str).innerHTML = "<div class='Disclaimer-input'>Promo Disclaimer:<br><textarea maxlength='1256' cols='40' rows='5' id='pdisclaimer' placeholder='Use <br> to insert a line break' name='pdisclaimer'></textarea><input name='Edit' type='button' class='EditCoup' id='EditCoup' value='Edit' onClick='javascript:updateCoupon("+id+",3);'></div>";
break;
case 4:
document.getElementById(str).innerHTML = "<div class='expDate'>Promo Experation:<br><input type='text' size='25' maxlength='100' id='datepicker' placeholder='DD-MM-YYYY' name='datepicker'><input name='Edit' type='button' class='EditCoup' id='EditCoup' value='Edit' onClick='javascript:updateCoupon("+id+",4);'></div>";
break;
case 5:
document.getElementById(str).innerHTML = "<div class='image-input'>Select a Promo Image:<br><select id='picture' name='picture'><option value='' Selected>Select Image...</option><option value='http://cws.dealerconnection.com/images/MAX.png'>Battery MAX</option><option value='http://cws.dealerconnection.com/images/PLUS.png'>Battery MAX</option><option value='http://cws.dealerconnection.com/images/brake.gif'>Brakes</option><option value='http://cws.dealerconnection.com/images/checkup.png'>Check List</option><option value='http://cws.dealerconnection.com/images/CreditCards.gif'>Ford Credit Card</option><option value='http://cws.dealerconnection.com/images/lptg.png'>Low Price Tire Gaurentee</option><option value='http://cws.dealerconnection.com/images/michelin.gif'>Michelin</option><option value='http://cws.dealerconnection.com/images/works.png'>The Works</option><option value='http://cws.dealerconnection.com/images/4tires.gif'>Tires</option><option value='http://cws.dealerconnection.com/images/TR99.png'>Tire Brand Logos</option><option value='http://cws.dealerconnection.com/images/wipers.png'>Wiper Blades</option><option value='http://cws.dealerconnection.com/images/Fpseal.png'>Warranty Ford Parts</option><option value='http://cws.dealerconnection.com/images/Mcseal.png'>Warranty Motocraft</option></select><input name='Edit' type='button' class='EditCoup' id='EditCoup' value='Edit' onClick='javascript:updateCoupon("+id+",5';'></div>";
break;
default:
alert("Error:"+formNum);
break;
}
}
</script>
AJAX：
var xmlhttp = '';
function createXMLHttpRequest() {
if (window.ActiveXObject) { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }
else if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); }
}
function updateCoupon(id,field)
{
var tempId = id;
switch( field )
{
case '1':
var updateField = "headline";
var title = form.ptitle.value;
var queryStr = "id=" + tempId + "&change=" + title + "&field=" +updateField;
break;
case '2':
var updateField = "subhead";
var desc = form.pdescription.value;
var queryStr = "id=" + tempId + "&change=" + desc + "&field=" +updateField;
break;
case '3':
var updateField = "disclaimer";
var disc = form.pdisclaimer.value;
var queryStr = "id=" + tempId + "&change=" + disc + "&field=" +updateField;
break;
case '4':
var updateField = "couponexpires";
var date = form.datepicker.value;
var queryStr = "id=" + tempId + "&change=" + date + "&field=" +updateField;
break;
case '5':
var updateField = "graphics";
var pic = form.picture.value;
var queryStr = "id=" + tempId + "&change=" + pic + "&field=" +updateField;
break;
}
createXMLHttpRequest();
var url = "/coupon_testing/Ford_coupon_tool/php/couponEdit.php?timeStamp=" + new Date().getTime();
xmlhttp.open("POST", url, true);
xmlhttp.onreadystatechange = function () {
if(xmlhttp.readyState == 4) {
if(xmlhttp.status == 200) {
var jResponse = xmlhttp.responseText;
if(jResponse != '') {
alert(jResponse);
}
}
}
};
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send(queryStr);
}
PHP：
<?php
$ret = "Error";
$id = $_POST['id'];
$change = trim($_POST['change']);
$field = trim($_POST['field']);
include 'configuration.inc.php';
include 'connection.inc.php';
include 'db_functions.inc.php';
//set variables from the coupon setup form
if( $id != '' && $change != '' && $field != '' )
{
//Saving the coupon to the database.
$sql = "UPDATE ford_coupons SET " . $field . "='" . addslashes($change)."' WHERE id='".addslashes($id)."' LIMIT 1";
execute_query($sql);
$ret = $field." has been updated!";
}
// print $ret;
$str = "id=".$id.", change=".$change.", field=".$field;
print $str;
?>
谁能告诉我这里的问题是什么？一直在绞尽脑汁和另一位程序员朋友，我们都不知道为什么不发布。感谢
答案 0 :(得分：0)
您正在使用数字值调用updateCoupon（id，field），例如
javascript:updateCoupon("+id+",1);
但是在你的switch语句中，你只是检查字符串值，比如
case '1':
您需要使用＆＃39;字段的字符串调用函数＆＃39;参数，或改变你的案例使用整数。
在执行期间，没有任何switch语句会被命中，因此空的AJAX请求......
