为什么弹出时不会更改第二个jQuery-UI对话框标题.第一个对话框我使用以下.attr("title", "Confirm")内容更改了框的标题 - 它将第一个框的标题更改为"确认",就像它应该具有的那样.现在,当弹出第二个框时,它应该将标题更改为"消息",因为对第二个框执行相同的操作 - .attr("title", "Message").对？但它没有.它保留了之前的标题.但是,消息会像它应该的那样改变.我已经在IE8,Chrome和FF3.6中进行了测试.

<div id="dialog-confirm" title=""></div> < - 这是jQuery函数之前的html.

Javascript/jQuery

$('#userDelete').click(function() {
$(function() {
var dialogIcon = "<span class=\"ui-icon ui-icon-alert\"></span>";
var dialogMessage = dialogIcon + "Are you sure you want to delete?";
$("#dialog-confirm").attr("title", "Confirm").html(dialogMessage).dialog({
    resizable: false,
    height:    125,
    width:     300,
    modal:     true,
    buttons:  {
    'Delete': function() {
        $(this).dialog('close');
        $.post('user_ajax.php', {action: 'delete',
                 aId: $('[name=aId]').val()
        }, function(data) {
            if(data.success){
                var dialogIcon = "<span class=\"ui-icon ui-icon-info\"></span>";
                var dialogMessage = dialogIcon + data.message;
                $('#dialog-confirm').attr("title", "Message");
                $('#dialog-confirm').html(dialogMessage);
                $('#dialog-confirm').dialog({ …

JavaScript能否Math.random()真正返回0或1？

如何在C#中动态创建数组？

码:

function SnakeGame() {
    "use strict";

    /***** Constant & Global Variables ***********************************/
    var canvas = $("#canvas")[0];
    var ctx  = canvas.getContext('2d');
    var width = $("#canvas").width();
    var height = $("#canvas").height();

    var snake, food;

    function Snake() {
    var startLength = 5; // default for starting size of snake
    this.body = [];

    this.chgStartLength = function(length) {
        startLength = length;
    };

    this.create = function() {
        var i;
        for(i=0; i>5; i++) {
        this.body.push({x:i, y:0});
        }
    };  
    }

    var paintCanvas = function() {
    ctx.fillStyle = 'white';
    ctx.fillRect(0, …
