我在编写订单提交页面时遇到了一个相当大的问题，该页面的目的是为订单提交争议 - 提供两个字段，但前提是一个字段小于另一个字段。

基本上，一个是下拉框，另一个是争议框，查询如下：

如果 DisputesTextBox = "" 并且下拉框 = "请选择..."

一切都很好 - 启用提交按钮

如果 DisputesTextBox != "" 并且下拉框 = "请选择..."

错误（反之亦然，因此如果填写了争议但 dropwn = 请选择...） - 提交按钮已禁用

如果 DisputesTextox != "" 并且下拉框 = "Other"

一切都很好 - 启用提交按钮

如果 DisputesTextBox > 装运箱

错误 - 提交按钮被禁用

<table>
                <thead>

                    <?php
                        $data = mysql_query("SELECT * FROM `artran09` WHERE `invno` = '$invoiceno'") or die(mysql_error());

                        echo "<form action=\"submitdispute.php?invno=".$invoiceno."&ordate=".$placed."\" method=\"POST\" onsubmit=\"return confirm('Are you sure you are ready to dispute your order?');\">";

                            while ($info = mysql_fetch_array($data)) {

    </div>
    <p><input type = "submit" value = "Dispute" name ="Submit">
    </form>

谢谢，希望有人能帮忙！

为 Wolf/任何可以提供帮助的人编辑 - 这里的代码是怎么回事：

-- 我编辑的代码 --

function validateSubmit(){


   // this will loop through each row in table
   // Make sure to include jquery.js
   $('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();
      // Add your validation code here for the inputs and select
      // Return true if all validations are correct
      // Else return false
        if(qty1 = "" && selectVal = "Please Select...") {
            return true;
            alert("You have an error somewhere, please check over your quantites.");
            break;
        }
        if (qty1 > qty2) {
            return false;
            alert("You have an error somewhere, please check over your quantites.");
            break;
        }
   });


}

更改以下行

onsubmit=\"return confirm('Are you sure you are ready to dispute your order?');\"

至

onsubmit=\"return validateSubmit();\"

然后写函数

function validateSubmit(){

   // this will loop through each row in table
   // Make sure to include jquery.js
   $('tr').each( function() {
      // Find first input
      var input1 = $(this).find('input').eq(0);

      // Find Second input
      var input2 = $(this).find('input').eq(1);

      // Find third input
      var input3 = $(this).find('input').eq(2);

      // Find select box
      var selectBx = $(this).find('select');

      // Add your validation code here for the inputs and select
      // Return true if all validations are correct
      // Else return false

   });
}

请注意，您的提交按钮将始终处于启用状态。但是仅当您的验证成功时提交才会起作用。
