Sharing instructions:

Inventing the wheel for the Nth time, just for the simplest call, jquery simulates alert and confirm pop-up window plug-ins

Calling method:

$.alert('your message');

$.alert('your message',function(){
 $.alert('click ok button')
});

$.confirm('your message');

$.confirm('your message',function(result){
 if(result){
  $.alert('click ok button')
 }else{
  $.alert('click cancel button')
 }
})

For the convenience of calling, the css style is written directly in js. In terms of compatibility, I have only tested IE8, chrome and safari, and they are all OK.
IE8 is fine, and other modern browsers should be fine as well.

(function ($) {
  $.extend({
    _isalert:0,
    alert:function(){
      if(arguments.length){
        $._isalert=1;
        $.confirm.apply($,arguments);
      }
    },
    confirm:function(){
      var args=arguments;
      if(args.length&&(typeof args[0] == 'string')&&!$('#alert_overlay').length){
        if(!$('#alert_style').length) $('body').append('<style id="alert_style" type="text/css">#alert_overlay{position:fixed;width:100%;height:100%;top:0;left:0;z-index:999;background:#000;filter:alpha(opacity=5);opacity:.05}#alert_msg{position:fixed;width:400px;margin-left:-201px;left:50%;top:20%;z-index:1000;border:1px solid #aaa;box-shadow:0 2px 15px rgba(0,0,0,.3);background:#fff}#alert_content{padding:20px;font-size:14px;text-align:left}#alert_buttons{padding:10px;border-top:1px solid #aaa;text-align:right;box-shadow:0 1px 0 #fff inset;background:#eee;-moz-user-select:none;-webkit-user-select:none;-ms-user-select:none}#alert_buttons .alert_btn{padding:5px 12px;margin:0 2px;border:1px solid #aaa;background:#eee;cursor:pointer;border-radius:2px;font-size:14px;outline:0;-webkit-appearance:none}#alert_buttons .alert_btn:hover{border-color:#bbb;box-shadow:0 1px 2px #aaa;background:#eaeaea}#alert_buttons .alert_btn:active{box-shadow:0 1px 2px #aaa inset;background:#e6e6e6}</style>');
        var dialog=$('<div id="alert_overlay"></div><div id="alert_msg"><div id="alert_content">'+args[0]+'</div><div id="alert_buttons"><button class="alert_btn alert_btn_ok">确定</button><button class="alert_btn alert_btn_cancel">取消</button></div></div>');
        if($._isalert) dialog.find('.alert_btn_cancel').hide();
        dialog.on('contextmenu',function(){
          return !1;
        }).on('click','.alert_btn_ok',function(){
          dialog.remove();
          if(typeof args[1]=='function') args[1].call($,!0);
        }).on('click','.alert_btn_cancel',function(){
          dialog.remove();
          if(typeof args[1]=='function') args[1].call($,!1);
        }).appendTo('body');
      }
      $._isalert=0;
    }
  });
})($);
