如何在javascript中显示Label.text [英] How to display Label.text in javascript

问题描述

我无法在javascript弹出窗口中显示我的标签..



我的.CS代码是

I'm unable to display my label in javascript popup ..

My .CS code is

ViewState["RcNo"] = stat;
      lblRcno.Text = "Receipt No: " + ViewState["RcNo"].ToString();

和我的.aspx代码是

and my .aspx Code is

function showMessage() {
            confirm(" Are you sure to print ? \n\n" + "      "
            + document.getElementById("<%=lblRcno.ClientID%>").innerHTML)
        }

确认框未在函数调用中打开

ScriptManager.RegisterStartupScript（Page，typeof（Page），message，showMessage（）;，true）;



但是当我在javascript中使用警报时

confirm box is not getting opened on function call
ScriptManager.RegisterStartupScript(Page, typeof(Page), "message", "showMessage();", true);

But when i'm using alert in javascript

function display() {
           alert(("<%=lblRcno.ClientID%>").innerHTML)

       }

显示未定义的

its showing undefined

推荐答案

替换双引号

Replace double quotes

"<%=lblRcno.ClientID%>"

单身

By single ones

'<%=lblRcno.ClientID%>'

并添加;在调用确认函数后;）

And add ";" after calling confirm function ;)

confirm(" Are you sure to print ? \n\n" + "      "
            + document.getElementById('<%=lblRcno.ClientID%>').innerHTML);
