I have a button and I wanted to program click of it, and when I use <asp:Button> I program click of it in code behind . I'm now using a button normal.
I know almost nothing about JavaScript and wanted to program it in code behind as well. Would I have created a JavaScript function by calling a C # method?
Step 1, on the server-side add method.
[WebMethod]
public static string Message(){
return " MENSAGEM ";
}
Step 2, search for the <asp:ScriptManager ID="..." runat="server" /> tag and add EnablePageMethods="true"
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />
Step 3, let's create a method in javascript
function getMessage() {
PageMethods.Message(OnGetMessageSuccess, OnGetMessageFailure);
}
Step 4, let's use a normal button ...
<input type='submit' value='Get Message' onclick='getMessage();return false;' />
If your implementation is restricted to an ASP.NET page with codebehind, you can implement a call to a WebMethod as follows:
Mark the method as a WebMethod . It must necessarily be a static method.
public partial class _Default : Page
{
[WebMethod]
public static string MetodoASerChamado()
{
return DateTime.Now.ToString();
}
}
Call the function directly from the javascript implementation.
$.ajax({
type: "GET",
url: "Default.aspx/MetodoASerChamado",
success: function(msg) {
// Do something interesting here.
}
});
Yes. You will need AJAXExtensionsToolbox in your project.
First, put the following on your page:
<asp:ScriptManager ID="ScriptManager1"
EnablePageMethods="true"
EnablePartialRendering="true" runat="server" />
In Code Behind , create the static method:
using System.Web.Services;
[WebMethod]
public static string MeuMetodo(string nome)
{
return "Oi, " + nome;
}
To call, you can do this:
<script type="text/javascript">
$("#botao").click(function () {
PageMethods.MeuMetodo("Cigano Morrison Mendez");
});
</script>
For example, I assume you have jQuery in your project.
Directly is impossible but ASP.Net has facilities for calling the client invoking what they need:
<asp:Button ID="botao" OnClick="botao_Click" runat="server" />
Then in Code-behind :
protected void botao_Click(object sender, EventArgs e) {
//faça o que quer aqui
}
