JS便签: 根据一个数值来改变Repeater行数的颜色 <script type="text/javascript"> var query = document.getElementsByClassName("kc"); for (var i = 0; i < query.length; i++) { var num = query[i]; var k = query[i].innerText; if (k >= 20) { } else { var hang = num.parentNode; hang.setAttribute("bgcolor", "#FF0033"); } } </script> 添加成功: Literal1.Text = "<script type='text/javascript'>alert('"+"添加成功"+"')</script>" 模糊查询: string ids = TextBox1.Text; string name = TextBox2.Text; DataClassesDataContext context = new DataClassesDataContext(); List<Fruit> list = context.Fruit.ToList(); if (ids != "") { list = list.Where(r => r.Ids.Contains(ids)).ToList(); } if (name != "") { list = list.Where(r => r.Name.Contains(name)).ToList(); } Repeater1.DataSource = list; Repeater1.DataBind();
