Animate jQuery UI dialog auto resize

问题

I have a dialog with a dynamic form inside that can increase the height of the dialog. autoResize is set to true, width is 500. Is there any way to animate the dialog resize when more content is added?

回答1:

Animating dialog size, while staying in the center of the screen

jQuery("#dialog").dialog("widget").animate({
    width: '400px', 
    height: '110px'
  }, {
  duration: 500,
  step: function() {
    jQuery("#dialog").dialog('option', 'position', 'center');
  }
});

Originally I was using .show('fade') and the size of the dialog would jump whenever .show was called. When using the effect .show('fast') or .show('slow'), the dialog is resized in a sliding fashion which works for me.

When i was using @Steven's answer i have issues with content size, like @jedierikb said in comment. So i created this code and it works.

$(dialogSel).dialog("widget").animate({
    width: 100,
    height: 200
}, {
    duration: 200,
    step: function (now, tween) {
        if (tween.prop == "width") {
            $(dialogSel).dialog("option", "width", now);
        } else {
            $(dialogSel).dialog("option", "height", now);
        }
    }
});
