jQuery -在PHP while循环中检查一个输入框与另一个输入框

我在编写订单提交页面时遇到了一个相当大的问题，该页面的目的是提交订单的争议-提供两个字段填写，但只有当一个字段小于另一个字段时。

基本上一个是下拉框，另一个是争议框，查询如下:

如果争端testextbox = "和下拉框= "Please Select…"

一切正常-提交按钮启用

如果testextbox = "和下拉框= "Please select…"

错误(反之亦然，所以如果争议填充但下拉=请选择…)-提交按钮禁用

如果

一切正常-提交按钮启用

错误-提交按钮被禁用

谢谢，希望有人能帮忙!

为Wolf/任何可以帮助的人编辑-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;
        }
   });

}

        return true;
        alert("You have an error somewhere, please check over your quantites.");
        break;
