我有一个循环，通过复选框输入输入，如果一切正常，它需要显示一个弹出框询问用户是否可以继续并提交订单，如果没有那么它需要做什么都没有（在其中处理）
我遇到了一些问题，无法弄清楚如何做，有什么想法吗？
这是我当前的代码
function validateSubmit(){
var r=true;
$('tr').each( function() {
// Find first input
var input1 = $(this).find('input').eq(0);
var qty1 = input1.val();
// Find Second input
var input2 = $(this).find('input').eq(1);
var qty2 = input2.val();
// Find third input
var input3 = $(this).find('input').eq(2);
var qty3 = input3.val();
// Find select box
var selectBx = $(this).find('select');
var selectVal = selectBx.val();
if(qty1 === '' && selectVal != 'Please Select...') {
alert("You've chosen an option, but not entered a quantity to dispute, please check your inputs.");
r=false;return false;
}
if(qty1 != '' && selectVal === 'Please Select...') {
alert("You've entered a quantity, but not chosen why, please check your reasons.");
r=false;return false;
}
if (qty1 > qty2) {
alert("For one of your entries, the disputed quantity is larger than the shipped quantity.");
r=false;return false;
}
});
if (r==true) {
var a = confirm("Are you sure you want to confirm the dispute? You cannot edit this after it's been submitted?");
if (a==true)
{
return true;
}
else
{
return false;
}
}
});
HTML：
<table>
<thead>
<tr><th>Item ID</th><th>Description</th><th>Dispute Quantity</th><th>Shipped Quantity</th><th>Ordered Quantity</th><th>Reason</th></tr>
</thead>
<tbody>
<?php
$data = mysql_query("SELECT * FROM `artran09` WHERE `invno` = '$invoiceno'") or die(mysql_error());
echo "<center>";
$i = -1;
echo "<form action=\"submitdispute.php?invno=".$invoiceno."&ordate=".$placed."\" method=\"POST\" onsubmit=\"return validateSubmit();\">";
while ($info = mysql_fetch_array($data)) {
$i += 1;
echo "<tr>";
echo "<td>".$info['item']."</td>";
echo "<td>".$info['descrip']."</td>";
echo "<td><input type=\"text\" input name=".$i." onKeyPress=\"return numbersonly(this, event)\" maxLength=\"3\"></td>";
echo "<td><input type=\"text\" value=".$info['qtyshp']." name = \"ship$i\" onKeyPress=\"return numbersonly(this, event)\" maxLength=\"3\" disabled=\"disabled\"></td>";
echo "<td><input type=\"text\" value=".$info['qtyord']." onKeyPress=\"return numbersonly(this, event)\" maxLength=\"3\" disabled=\"disabled\"></td>";
echo "<td><select name = \"reason$i\">";
echo "<option>Please Select...</option>";
echo "<option>Short/Not received</option>";
echo "<option>Damaged Goods</option>";
echo "<option>Product Not Ordered</option>";
echo "</select></td>";
echo "</tr>";
}
?>
</tbody>
</table>
</div>
</div>
<p><input type = "submit" value = "Dispute" name ="Submit">
</form>
对于任何有兴趣的人 - 我已经解决了这个问题！ 谢谢大家的耐心！这是修复：
function validateSubmit(){
var r=true;
$('tr').each( function() {
// Find first input
var input1 = $(this).find('input').eq(0);
var qty1 = input1.val();
// Find Second input
var input2 = $(this).find('input').eq(1);
var qty2 = input2.val();
// Find third input
var input3 = $(this).find('input').eq(2);
var qty3 = input3.val();
// Find select box
var selectBx = $(this).find('select');
var selectVal = selectBx.val();
if(qty1 === '' && selectVal != 'Please Select...') {
alert("You've chosen an option, but not entered a quantity to dispute, please check your inputs.");
r=false;return false;
}
if(qty1 != '' && selectVal === 'Please Select...') {
alert("You've entered a quantity, but not chosen why, please check your reasons.");
r=false;return false;
}
if (qty1 > qty2) {
alert("For one of your entries, the disputed quantity is larger than the shipped quantity.");
r=false;return false;
}
});
if (r=true) {
var a = confirm("Are you sure you wish to dispute? You cannot dispute this order again once submitted.");
return a;
}
}
