如何通过 jquery 或 java 脚本触发 asp.net 按钮事件？

Question

I want when I click on "Doit" string it fire my asp.net button.

This is my "DoIt"

<a id="" href="#"">Doit</a>

And my asp.net button event is:

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Redirect("rightclick.aspx");
}

How can I do this? Please help me..

Answer 1

If Button1 already exists, have such code:

<a id="myLink" href="#" onclick="document.getElementById('<%=Button1.ClientID%>').click(); return false;">Doit</a>

This will "auto click" the button thus trigger any server side code handling its click.

Answer 2

Try:

<asp:LinkButton ID="MyLink" runat="server" onclick="Button1_Click">Doit</asp:LinkButton>

Answer 3

use the LinkButton ASP control to fire that event

<asp:LinkButton id="something" onClick="Button1_Click" Text="DoIt" runat="server" />

Answer 4

To call a server side method on a client side event you need to do the following:

1- Create the server side method:

void DoSomething(...) { ... }

2- Implement the System.Web.UI.IPostBackEventHandler.RaisePostBackEvent which take one string argument (You can assign the name to the value of this argument).:

public void RaisePostBackEvent(string eventArgument) 
{
        DoSomething(...);
}

3- Write a script to trigger post back:

function TriggerPostBack(control, arg){
    __doPostBack(control, arg);
}

4- Call the PostBack trigger function when needed:

<a .... onclick="TriggerPostBack('control', 'arg')" .. /> 

Answer 5

Above answers are generating HTML, if you want to invoke from JavaScript use:

__doPostBack('<your controls UniqueID>',''); 

But you will need to have an asp control on your page either way...

Answer 6

<script>
    function GO(){
        $("#<%=btnGo.ClientID=%>").click();
    }
</script>

<a id="" href="GO();"">Doit</a>

<asp:Button id="btnGo" onClick="Button1_Click">

i didn't test this, but, this is the basic ideia, if you don't wanna use the LinkButton (that is the best option)

PS: If you are using framework 4.0, you can use the clientid static. PS2: if want, you can hide the button, but again, the best way to do this is with LinkButton.

EDIT: Are you only trying redirect to another page??? oO???
