self.goToPage(cur + );
};
};
self.StartPageDot = function () {
var page = self.start() - Math.floor(self.pagerCount / );
if (page < ) {
page = ;
}
self.goToPage(page);
}
self.EndPageDot = function () {
var page = self.end() + Math.floor(self.pagerCount / );
if (page > self.pageCount()) {
page = self.pageCount();
}
self.goToPage(page);
}
//跳转
self.jump = function () {
var page = self.jumpPage();

};
};
};
分页使用时，要给ViewModel添加Refresh方法，具体的js代码里面有
分页也要用两部分的html代码，分别在上面的html中有
