jquery封装的对话框简单实现

var _alert_iconCss = "tipmsg_icoInfo"; 
var _confirm_iconCss = "tipmsg_icoConfirm"; 
var _error_iconCss = "tipmsg_icoError"; 
var _warning_iconCss = "tipmsg_icoWarning";

case "warning" : iconCss = _warning_iconCss; break; 
default : iconCss = _alert_iconCss; break; 
} var htmlStr = "<div id='" + type + "Div' style='display: none;'><p><span class='" + iconCss + "' style='float:left; margin:0 7px 50px 0;width:35px;height:35px;'></span>" + msg + "</p></div>"; 
return htmlStr; 
} 
function Alert(msg, okCallback) { 
var title = "提示"; 
var type = "alert"; 
var html = dialogInit(type, msg); 
var div = $("body").find("#"+type+"Div"); 
div.remove();
