how can i get the button's command argument?

Question

Is it possible to get a button's command argument in javascript. I don't want to manipulate it, i just want to read it.

If possible - how?

Effectively you want to know the javascript you're that is executing? – Sarmentose

Huh? I want to be able to get the command argument for a button given a client id. – Scincoid

"command argument" and "client id" aren't really javascript terms; do you mean "onclick" and "id"? – Eschew

Answer 1

Make your own attribute and get it with standard JavaScript:

Markup:

<asp:LinkButton ID="LinkButton1" cmdname="test" CommandName="test" CommandArgument="1" 
    runat="server" onclick="LinkButton1_Click">LinkButton</asp:LinkButton>

Script:

//however you choose to get the element, jQuery...etc
document.getElementById('<%=LinkButton1.ClientID %>').cmdname

you are a beast!! I didn't know you can make up your own property. I've been at this for hours now!!! thanks rick!! if i could give you more points i would. – Scincoid

To use correct HTML5 (though it works fine in older HTML too!) you should prefix your custom attribute with data-. So you'd have data-cmdname. See tinyurl.com/6uycchj – Fontana

Answer 2

You can put command argument into some hidden field, then retrieve the value of the hidden field in javascript after page loads such as $(document).ready() in JQuery.

This is the only way. The command argument exists only on the server side as far as I know. – Liegeman

Answer 3

The short answer is NO if you are ONLY using javascript. But you could retrieve it with an ajax call to the server or using a hidden field like J.W. suggested. This property is not even accessible from themes. For more info read the documentation in msdn

JS :
------
function get_id(obj) {
    var my_eval = obj.getAttribute("name");
    alert(my_eval);
}

<input type="button" id="btn" value="My Btn" onclick="get_id(this);" name='<%# Eval("item_id") %>' />
