在jQuery中獲取值undefined形式字符串bulider

我通過post方法發送一些值到jquery ajax方法中使用字符串bulider在服務器端編碼的php頁面。但是當我嘗試發送值是說undefined.i dono如何通過cliendid.it是否正確？在jQuery中獲取值undefined形式字符串bulider

 protected void btnAdd_Click(object sender, EventArgs e) 
    { 

     c.MyQuery("insert into tblHrims_currentOpeningsNew(nvrDesignation,nvrCompany,nvrExperience,nvrLocation,nvrEducation,nvrDepartment,nvrIndustryType,nvrFnalArea,nvrJobDesc,nvrDesiredProfile,nvrContactPerson," + 
" nvrContactNumber,nvrEmailId,nvrWantedPositions,nvrAddedBy,dttAddedon) values('" + txtDesg.Text.Trim().Replace("'", "") + "','" + ddlCompany.SelectedItem.Text + "','" + txtExperience.Text + "','" + txtLocation.Text + "','" + txtEducation.Text + "'," +

在什麼行是「未定義」 - 你檢查了瀏覽器的控制檯（F12）？什麼看起來像JavaScript在HTML中？ –

看到我將發送這個測試箱的值爲PHP ....所以這些值我越來越未定義... –

您需要將客戶端ID直接包含在生成的腳本中，而不是使用指令加載它們。

例如，改變下列行：

mystringbuilder.Append("  var ddlCompany = $(\"#<%=this.ddlCompany.ClientID %>\").attr('value'); \n");

到：

mystringbuilder.Append("  var ddlCompany = $("').Append(this.ddlCompany.ClientID).Append("').attr('value');").AppendLine();

此外，應更換\n s的AppendLine（）如在上面的例子。

不，我已經宣佈了一條線，我檢查，JavaScript本身不工作... –

@competent_tech。我認爲你錯過了jQuery對象中ClientID的引號。應該是：'mystringbuilder.Append（「var ddlCompany = $（'」）。Append（this.ddlCompany.ClientID）.Append（「'）。attr（'value'）;」）。AppendLine（）;' –

@ DidierG。感謝趕上，它已經很晚了。 –
