jquery - 定位对话框

Question

我正在尝试在 jQuery 中定位一个对话框，并且我有以下代码。它似乎没有做我期望的事情。我只需要对话框居中或出现在我 body 的左上角。

这是我的代码

    agreeDialog = $j('#termsOfAgreementConfirm').dialog({
                modal: true,
                autoOpen:false,
                resizable:false,
                width : 1000,
                height :400,
                stack:false,
                closeOnEscape:false,
                title:"Terms of Usage",
                open: function(event, ui) {

                    $j('.ui-dialog-titlebar-close').hide();

                },
                buttons: {

                    Disagree: function() {
                        disagree.dialog('open');
                        disagree.dialog('moveToTop');

                    },


                    Agree: function() {
                        $j(this).dialog('close');
                        $j.cookie("agree", "Y");
                        new Ajax.Request('/myballback/user/ajaxUpdateAgreementForUser',
                                {
                                    onSuccess:function(resp) {
                                    },
                                    onError: function(resp) {
                                        alert("Error:" + resp.toJSON());
                                        return;
                                    },
                                    asynchronous:true,
                                    evalScripts:true
                                });
                        $j(this).dialog('close');

                    }
                }
            });


var x = jQuery(agreeDialog).position().left + jQuery(agreeDialog).outerWidth();
            var y = jQuery(agreeDialog).position().top - jQuery(document).scrollTop();               //agreeDialog.dialog({width:width, height:height ,position:[posX, posY]});


            agreeDialog.dialog('option', 'position',[x, y]);

你为什么不尝试一下:

$( ".selector" ).dialog( "option", "position", ['left','top'] );

或

$( ".selector" ).dialog( "option", "position", 'center' );
