javascript - 如何在 Asp.Net 按钮单击事件上将值从 C# 发送到 javascript？

Question

我正在尝试将 C# 值提取到 JavaScript 中，任何人都可以帮助我解决这个问题。

ASP.NET 代码

 <asp:Button runat="server" Text="Submit"   class="btn btn-success btn-lg" ID="btnsubmit" OnClick="btnsubmit_Click"/>

C# 代码

protected void btnsubmit_Click(object sender, EventArgs e)
{
   string abc="xyz";
   // From here i need to Call JavaScript Function 
   // suppose code is like myfunction(abc)<-Java script function
   myfunction(abc);
}

Javascript

<script type="javascript/text">

  function myfunction(abc){
    var val = abc
    console.log(val);
    // here i want to get abc value is this possible
  }

</script>

您可以使用ClientScriptManager.RegisterStartupScript方法。

Registers the startup script with the Page object using a type, a key, a script literal.

代码

 protected void btnsubmit_Click(object sender, EventArgs e)
 {
      string abc="xyz";       

      //If the string can contain apostrophes or backslashes, you would need to escape them
      string value = abc.Replace("\\", "\\\\").Replace("'", "\\'");
      Page.ClientScript.RegisterStartupScript(this.GetType(),"CallMyFunction","myfunction('" +value + "')",true);
 }
