推荐答案

嗨 拉杰什，


我以为:
按钮名称:btnSave
文本框名称:txtAdd

服务器端代码:

Hi Rajesh,


I assumed:
Button Name: btnSave
Textbox Name: txtAdd

Server side code:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            btnSave..Attributes.Add("onclick","return checkValidation();");
        }
    } 

Javascript代码:

Javascript code:

function checkValidation()
{
    var txt = document.getElementById('<%= txtAddlientID %>');
    if(txt.value == '')
    {
        alert('Please enter data before save!');
        return false;
    }
   return true;
}

如有任何疑问，请让我知道.

OnClientClick ="return Isnotesempty()";

OnClientClick="return Isnotesempty()";

function Isnotesempty()
{
    if(document.getElementById (objid).value=="")
    {
        alert("Description should not be empty...!");
        document.getElementById (objid).focus();
        return false;
    }
    return true;
}

祝您编码愉快.

Happy Coding.

如果txtbox.text！="然后

如果文本框文本不为空，将执行

if txtbox.text != "" then

will execute if the textbox text is not empty
