C# ASP.NET MVC HtmlHelper用法大全
HTML扩展类的所有方法都有2个参数:
以textbox为例子
public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, IDictionary<string, Object> htmlAttributes )
public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, Object htmlAttributes )
这2个参数代表这个html标签的属性集合。使用方法如下。
1.ActionLink
<%=Html.ActionLink( "这是一个连接" , "Index" , "Home" )%> 带有QueryString的写法 <%=Html.ActionLink( "这是一个连接" , "Index" , "Home" , new { page=1 }, null )%> <%=Html.ActionLink( "这是一个连接" , "Index" , new { page=1 })%> 有其它Html属性的写法 <%=Html.ActionLink( "这是一个连接" , "Index" , "Home" , new { id= "link1" })%> <%=Html.ActionLink( "这是一个连接" , "Index" , null , new { id= "link1" })%> QueryString与Html属性同时存在 <%=Html.ActionLink( "这是一个连接" , "Index" , "Home" , new { page = 1 }, new { id = "link1" })%> <%=Html.ActionLink( "这是一个连接" , "Index" , new { page = 1 }, new { id = "link1" })%> 生成结果为: <a href=http://www.mamicode.com/ "/" >这是一个连接</a> 带有QueryString的写法 <a href=http://www.mamicode.com/ "/?page=1" >这是一个连接</a> <a href=http://www.mamicode.com/ "/?page=1" >这是一个连接</a> 有其它Html属性的写法 <a href=http://www.mamicode.com/ "/?Length=4" id= "link1" >这是一个连接</a> <a href=http://www.mamicode.com/ "/" id= "link1" >这是一个连接</a> QueryString与Html属性同时存在 <a href=http://www.mamicode.com/ "/?page=1" id= "link1" >这是一个连接</a> <a href=http://www.mamicode.com/ "/?page=1" id= "link1" >这是一个连接</a> |
2.RouteLink
跟ActionLink在功能上一样。 <%=Html.RouteLink( "关于" , "about" , new { })%> 带QueryString <%=Html.RouteLink( "关于" , "about" , new { page = 1 })%> <%=Html.RouteLink( "关于" , "about" , new { page = 1 }, new { id = "link1" })%> 生成结果: <a href=http://www.mamicode.com/ "/about" >关于</a> <a href=http://www.mamicode.com/ "/about?page=1" >关于</a> <a href=http://www.mamicode.com/ "/about?page=1" id= "link1" >关于</a> |
<% using (Html.BeginForm( "index" , "home" ,FormMethod.Post)){%> <%} %> <%Html.BeginForm( "index" , "home" , FormMethod.Post); //注意这里没有=输出%> <%Html.EndForm(); %> 生成结果: <form action= "/home/index" method= "post" ></form> |
4.TextBox , Hidden ,
<%=Html.TextBox( "input1" ) %> <%=Html.TextBox( "input2" ,Model.CategoryName, new { @style = "width:300px;" }) %> <%=Html.TextBox( "input3" , ViewData[ "Name" ], new { @style = "width:300px;" }) %> <%=Html.TextBoxFor(a => a.CategoryName, new { @style = "width:300px;" })%> 生成结果: <input id= "input1" name= "input1" type= "text" value=http://www.mamicode.com/ "" /> <input id= "input2" name= "input2" style= "width:300px;" type= "text" value=http://www.mamicode.com/ "Beverages" /> <input id= "input3" name= "input3" style= "width:300px;" type= "text" value=http://www.mamicode.com/ "" /> <input id= "CategoryName" name= "CategoryName" style= "width:300px;" type= "text" value=http://www.mamicode.com/ "Beverages" /> |
<%=Html.TextArea( "input5" , Model.CategoryName, 3, 9, null )%> <%=Html.TextAreaFor(a => a.CategoryName, 3, 3, null )%> 生成结果: <textarea cols= "9" id= "input5" name= "input5" rows= "3" >Beverages</textarea> <textarea cols= "3" id= "CategoryName" name= "CategoryName" rows= "3" >Beverages</textarea> |
<%=Html.CheckBox( "chk1" , true ) %> <%=Html.CheckBox( "chk1" , new { @ class = "checkBox" }) %> <%=Html.CheckBoxFor(a =>a.IsVaild, new { @ class = "checkBox" })%> 生成结果: <input checked = "checked" id= "chk1" name= "chk1" type= "checkbox" value=http://www.mamicode.com/ "true" /><input name= "chk1" type= "hidden" value=http://www.mamicode.com/ "false" /> <input class = "checkBox" id= "chk1" name= "chk1" type= "checkbox" value=http://www.mamicode.com/ "true" /><input name= "chk1" type= "hidden" value=http://www.mamicode.com/ "false" /> <input checked = "checked" class = "checkBox" id= "IsVaild" name= "IsVaild" type= "checkbox" value=http://www.mamicode.com/ "true" /><input name= "IsVaild" type= "hidden" value=http://www.mamicode.com/ "false" /> |
<%=Html.ListBox( "lstBox1" ,(SelectList)ViewData[ "Categories" ])%> <%=Html.ListBoxFor(a => a.CategoryName, (SelectList)ViewData[ "Categories" ])%> 生成结果: < select id= "lstBox1" multiple= "multiple" name= "lstBox1" > <option value=http://www.mamicode.com/ "1" >Beverages</option> <option value=http://www.mamicode.com/ "2" >Condiments</option> <option selected= "selected" value=http://www.mamicode.com/ "3" >Confections</option> <option value=http://www.mamicode.com/ "4" >Dairy Products</option> <option value=http://www.mamicode.com/ "5" >Grains/Cereals</option> <option value=http://www.mamicode.com/ "6" >Meat/Poultry</option> <option value=http://www.mamicode.com/ "7" >Produce</option> <option value=http://www.mamicode.com/ "8" >Seafood</option> </ select > < select id= "CategoryName" multiple= "multiple" name= "CategoryName" > <option value=http://www.mamicode.com/ "1" >Beverages</option> <option value=http://www.mamicode.com/ "2" >Condiments</option> <option value=http://www.mamicode.com/ "3" >Confections</option> <option value=http://www.mamicode.com/ "4" >Dairy Products</option> <option value=http://www.mamicode.com/ "5" >Grains/Cereals</option> <option value=http://www.mamicode.com/ "6" >Meat/Poultry</option> <option value=http://www.mamicode.com/ "7" >Produce</option> <option value=http://www.mamicode.com/ "8" >Seafood</option> </ select > |
<%= Html.DropDownList( "ddl1" , (SelectList)ViewData[ "Categories" ], "--Select One--" )%> <%=Html.DropDownListFor(a => a.CategoryName, (SelectList)ViewData[ "Categories" ], "--Select One--" , new { @ class = "dropdownlist" })%> 生成结果: < select id= "ddl1" name= "ddl1" > <option value=http://www.mamicode.com/ "" >--Select One--</option> <option value=http://www.mamicode.com/ "1" >Beverages</option> <option value=http://www.mamicode.com/ "2" >Condiments</option> <option selected= "selected" value=http://www.mamicode.com/ "3" >Confections</option> <option value=http://www.mamicode.com/ "4" >Dairy Products</option> <option value=http://www.mamicode.com/ "5" >Grains/Cereals</option> <option value=http://www.mamicode.com/ "6" >Meat/Poultry</option> <option value=http://www.mamicode.com/ "7" >Produce</option> <option value=http://www.mamicode.com/ "8" >Seafood</option> </ select > < select class = "dropdownlist" id= "CategoryName" name= "CategoryName" > <option value=http://www.mamicode.com/ "" >--Select One--</option> <option value=http://www.mamicode.com/ "1" >Beverages</option> <option value=http://www.mamicode.com/ "2" >Condiments</option> <option value=http://www.mamicode.com/ "3" >Confections</option> <option value=http://www.mamicode.com/ "4" >Dairy Products</option> <option value=http://www.mamicode.com/ "5" >Grains/Cereals</option> <option value=http://www.mamicode.com/ "6" >Meat/Poultry</option> <option value=http://www.mamicode.com/ "7" >Produce</option> <option value=http://www.mamicode.com/ "8" >Seafood</option> </ select > |
webform里叫自定义控件。功能都是为了复用。但使用上自定义控件真的很难用好。 <% Html.RenderPartial( "DinnerForm" ); %> 看清楚了没有等号的。 C# ASP.NET MVC HtmlHelper用法大全 HTML扩展类的所有方法都有2个参数: 以textbox为例子 public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, IDictionary<string, Object> htmlAttributes ) public static string TextBox( this HtmlHelper htmlHelper, string name, Object value, Object htmlAttributes ) 这2个参数代表这个html标签的属性集合。使用方法如下。 1.ActionLink
