Question

下面的代码是我写的一些JavaScript。

标记的行显示错误：

<script language="javascript" type="text/javascript">
    function ValidateOffpoint( )
    {
        var txt= document.getElementById('txtOffpoint')  
        if (txt.value.length<=3)
        {
            txt.focus()
            return;
        } 
        if (txt.value=="No Record Found" || txt.value=="")
        {
            txt.value=""
            txt.focus()
            return;
        }
    }

    function ConvertToUpperOffPoint()
    {  
        var txtOffpoint = document.getElementById("txtOffpoint"); 
        txtOffpoint.value = txtOffpoint.value.toUpperCase();     
    }

    function CheckTxtBox()
    {       
        strTextBoxVal = document.getElementById('txtOffpoint');
// ############################ Error in next line ############################
        strOrigin = Session("LocCode")

        if(strTextBoxVal.value.length > 0 )
        {
            if(strTextBoxVal.value.length < 3 )
            {
                lblErrMsg.innerText = "Flight Offpoint should not be less than 3 characters";
                strTextBoxVal.focus();
                return false;
            }
        }

        if (strTextBoxVal.value.substring(0,3) == strOrigin)
        {
            lblErrMsg.innerText = "Origin and Flight OffPoint cannot be the same.";
            strTextBoxVal.focus();
            return false;
        }

        if(strTextBoxVal.value=="" )
        {
            if (document.getElementById("hdnHandled").value=="true")
            {
                lblErrMsg.innerText = "Flight Offpoint is required field for Handled Airline.";
                strTextBoxVal.focus();
                return false;
            }
        }

        lblErrMsg.innerText = "";
        return  validateFlightNo();
    }
</script>

请帮帮我。 :-(

您正在将服务器端代码与客户端代码混合使用。将功能更改为：

function CheckTxtBox()
    {     

      strTextBoxVal = document.getElementById('txtOffpoint');
      strOrigin = "<%=Session("LocCode")%>";
      if(strTextBoxVal.value.length > 0 )
      {
        if(strTextBoxVal.value.length < 3 )
        {
            lblErrMsg.innerText = "Flight Offpoint should not be less than 3 characters";
            strTextBoxVal.focus();
            return false;
        }
      }

我的猜测是构造函数Session存在并且您打算使用：

strOrigin = new Session("LocCode")

Javascript错误：需要对象
