jquery-ui Dialog: Make a button in the dialog the default action (Enter key)

Question

In a jquery modal dialog, is there a way to select a button as the default action (action to execute when the user presses enter)?

Example of jquery web site: jquer

Answer 1

In my case, none of the answers worked because I called .dialog on an empty div and added my buttons dynamically, so the $(this).html() would return nothing. So I couldn't call methods like parent() or siblings() and expect something in return. What I did was select the ui-dialog-buttonpane class directly and find the button element from there

HTML

Jquery

$("#dialogexample").dialog({
    autoOpen: false,
    modal: true,
    open: function () {
        $('.ui-dialog-buttonpane').find('#otherbutton').focus();
    }
});
var buttons = {
    "MyButton" : {
        text: "Do Stuff",
        id: "dostuffbutton" 
    },
    "OtherButton" : {
        text: "Other Stuff",
        id: "otherbutton"
    }
} 
$("#dialogexample").dialog("option", "buttons", buttons);
$("#dialogexample").dialog("open"); //the second (otherbutton), instead of
                                    //the first (dostuffbutton) button should be focused
