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="/">这是一个连接</a>带有QueryString的写法<a href="/?page=1">这是一个连接</a><a href="/?page=1">这是一个连接</a>有其它Html属性的写法<a href="/?Length=4" id="link1">这是一个连接</a><a href="/" id="link1">这是一个连接</a>QueryString与Html属性同时存在<a href="/?page=1" id="link1">这是一个连接</a><a href="/?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="/about">关于</a><a href="/about?page=1">关于</a><a href="/about?page=1" id="link1">关于</a>3.Form 2种方法<%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="" /><input id="input2" name="input2" style="width:300px;" type="text" value="Beverages" /><input id="input3" name="input3" style="width:300px;" type="text" value="" /><input id="CategoryName" name="CategoryName" style="width:300px;" type="text" value="Beverages" /> 5.TextArea<%=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> 6.CheckBox<%=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="true" /><input name="chk1" type="hidden" value="false" /> <input class="checkBox" id="chk1" name="chk1" type="checkbox" value="true" /><input name="chk1" type="hidden" value="false" /> <input checked="checked" class="checkBox" id="IsVaild" name="IsVaild" type="checkbox" value="true" /><input name="IsVaild" type="hidden" value="false" /> 7.ListBox<%=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="1">Beverages</option><option value="2">Condiments</option><option selected="selected" value="3">Confections</option><option value="4">Dairy Products</option><option value="5">Grains/Cereals</option><option value="6">Meat/Poultry</option><option value="7">Produce</option><option value="8">Seafood</option></select><select id="CategoryName" multiple="multiple" name="CategoryName"><option value="1">Beverages</option><option value="2">Condiments</option><option value="3">Confections</option><option value="4">Dairy Products</option><option value="5">Grains/Cereals</option><option value="6">Meat/Poultry</option><option value="7">Produce</option><option value="8">Seafood</option></select> 8.DropDownList<%= 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="">--Select One--</option><option value="1">Beverages</option><option value="2">Condiments</option><option selected="selected" value="3">Confections</option><option value="4">Dairy Products</option><option value="5">Grains/Cereals</option><option value="6">Meat/Poultry</option><option value="7">Produce</option><option value="8">Seafood</option></select><select class="dropdownlist" id="CategoryName" name="CategoryName"><option value="">--Select One--</option><option value="1">Beverages</option><option value="2">Condiments</option><option value="3">Confections</option><option value="4">Dairy Products</option><option value="5">Grains/Cereals</option><option value="6">Meat/Poultry</option><option value="7">Produce</option><option value="8">Seafood</option></select> 9.Partial 视图模板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。
