显示“等待几秒”

每次从一个页面跳转到控制层处理，然后回跳到页面时，显示"请等待..."

用js控制:

 eg:

 function showProcessing(msg,timeout,width,height){

      var sMsg=isString(msg)?msg:'';

      var iTimeout=isNumber(timeout) ? timeout :60000;

      var cssStyle = new Object();

      if(isNumber(width)){

        cssStyle['width']=width;

   }

    if(isNumber(height)){

       cssSyle['height'] = height;

   }

 

   $.blockUI({

     message:sMsg,

    timeout:iTimeout,

    css:cssStyle

});

 

}

 

function isString(obj){

     return compareObject(obj,'');

}

function isNumber(obj){

   return compareObject(obj,0);

}

function compareObject(obj1,obj2){

    var rtn=false;

    try{

      rtn=obj1.constructor.name == obj2.constructor.name;

  }catch(e){

      rtn=false;

 }

  return rtn;

}

 

 

至此，完成。在需要调用的时候只需:showProcessing('正在加载数据，请稍后..');
