jQuery Ui Dialog Buttons, How to add class?

问题

I found this answer on another thread..

How to add multiple buttons in Jquery UI dialog box?

Using this syntax, how do you add class to a particular button?

 $("#mydialog").dialog({
      buttons: {
        'Confirm': function() {
           //do something
           $(this).dialog('close');
        },
        'Cancel': function() {
           $(this).dialog('close');
        }
      }
    });

It doesn't look like there's a great way to do this via the API, however you could add the classes in an event handler for create:

$("#dialog").dialog({
    buttons: {
        'Confirm': function() {
            //do something
            $(this).dialog('close');
        },
        'Cancel': function() {
            $(this).dialog('close');
        }
    },
    create:function () {
        $(this).closest(".ui-dialog")
            .find(".ui-button:first") // the first button
            .addClass("custom");
    }
});

If you wanted the second button, you could use:

$(this).closest(".ui-dialog").find(".ui-button").eq(1).addClass("custom") // The second button

The key is the $(this).closest(".ui-dialog").find(".ui-button"), which will select the buttons in your dialog. After that, you could apply any selector you want (including :contains(...) which might be useful if you want to select a button based on its text instead of its order).

Here's an example: http://jsfiddle.net/jjdtG/

Also note that the CSS selector for the style(s) you want to apply has to be more specific than jQueryUI's built-in selectors in order for the styling to be applied.

You Can add class to the button's in Dialog...by

$('#mydialog').dialog({
  buttons:{
    "send":{
      text:'Send',
      'class':'save'
    },
    "cancel":{
      text:'Cancel',
      'class':'cancel'
    }
  });

I think this will work for you. and you can find more answers here.

            "Cancel": {
                    click: function () {
                        $(this).dialog("close");
                    },
                    text: 'Cancel',
                    class: 'custom-class'
                }
          }
        });

Use the open event handler:

open: function(event) {
     $('.ui-dialog-buttonpane').find('button:contains("Cancel")').addClass('cancelButton');
 }

Clean, simple, piece of cake!

Thanks to LintonB, you can add all of the property attached to a button like style, id, etc...

dialog_options.buttons = {
  'Modify': {
    click: function() {

      $(this).dialog('close');

      if (inputs.phone !== '') {
        inputs.phone.focus();
        inputs.phone[0].value = "";
      }
    },
    class: 'btn btn-labeled btn-warning',
    style: 'margin-right: 30px;',
    id: 'modificationId'
  },
  'Keep': {
    click: function() {
      $(this).dialog('close');

      _this.validatePhone(i);

    },
    class: 'btn btn-labeled btn-warning',
    id: 'conserverId'
  }
};
