discuz二次开发笔记（二）------跳转函数运用，discuz二次开发      前几天在增加修改功能时，突然用到一个提示函数，有点不理解，看了他的由来后果断做下笔记，感觉这在以后的开发中肯定还是要用的上的。有些地方不是很理解，在以后慢慢纠正、查补。
htm页面中用的js跳转：
$(#lyy_real).click(function(){
    $.post(api/realnamechange.php,
            {uname:$(#uname).val(),uid:$(#uid).val(),realname:$(#realname_lyy).val()},
            function(data){  数据返回执行弹出框，并刷新当前页面。
                popup.open(data, 'confirm', 'home.php?mod=space&uid='+$(#uid).val());
            }
          );
  })
common.js
var popmenu = new object;
var popup = {
         init : function() {
                   var $this = this;
                   $('.popup').each(function(index, obj) {
                            obj = $(obj);
                            var pop = $(obj.attr('href'));
                            if(pop && pop.attr('popup')) {
                                     pop.css({'display':'none'});
                                     obj.on('click', function(e) {
                                               $this.open(pop);
                                     });
                            }
                   });
                   this.maskinit();
         },
         maskinit : function() {
                   var $this = this;
                   $('#mask').off().on('tap', function() {
                            $this.close();
                   });
         },
open : function(pop, type, url) {
                   this.close();
                   this.maskinit();
                   if(typeof pop == 'string') {
                            $('#ntcmsg').remove();
                            if(type == 'alert') {
                                     pop = '
'+ pop +'
'                            } else if(type == 'confirm') {
                                     pop = '
'+ pop +'取消
'                            }
                            $('body').append('
'+ pop +'
');                            pop = $('#ntcmsg');
                   }
                   if(popmenu[pop.attr('id')]) {
                            $('#' + pop.attr('id') + '_popmenu').html(pop.html()).css({'height':pop.height()+'px', 'width':pop.width()+'px'});
                   } else {
                            pop.parent().append('
'+ pop.html() +'
');                   }
                   var popupobj = $('#' + pop.attr('id') + '_popmenu');
                   var left = (window.innerwidth - popupobj.width()) / 2;
                   var top = (document.documentelement.clientheight - popupobj.height()) / 2;
                   popupobj.css({'display':'block','position':'fixed','left':left,'top':top,'z-index':120,'opacity':1});
                   $('#mask').css({'display':'block','width':'100%','height':'100%','position':'fixed','top':'0','left':'0','background':'black','opacity':'0.2','z-index':'100'});
                   popmenu[pop.attr('id')] = pop;
         },
         close : function() {
                   $('#mask').css('display', 'none');
                   $.each(popmenu, function(index, obj) {
                            $('#' + index + '_popmenu').css('display','none');
                   });
         }
};
上面是popup的定义，下面是他的三种用法：
popup.open('要输出的提示信息', 'confirm', '点击确定按钮后要跳转的地址'); confirm为弹出提示框的方式，这种方式有确认和取消两种按钮，点击确定后才会跳转。
popup.open('要输出的提示信息', 'alert');alert为弹出提示框的方式，这种方式只有一个确定按钮，如果下面有跳转链接，不点击也会在默认时间内跳转页面。
popup.close();隐藏当前窗体
