所有标签定义方法:
public static string SelfDefineTagString(this HtmlHelper helper, string tagName, string id, string name, string className,string value, string style)
{
//创建标签
TagBuilder tb = new TagBuilder(tagName);
//定义标签id
tb.GenerateId(id);
//定义标签name
tb.MergeAttribute("name", name);
//定义标签class
tb.AddCssClass(className);
//定义标签样式
tb.MergeAttribute("style", style);
//定义标签内容
tb.SetInnerText(value);
return tb.ToString();
} public static HtmlString SelfDefineTag(this HtmlHelper helper, string tagName, string id, string name, string className,string value, string style)
{
return new HtmlString(SelfDefineTagString(helper, tagName, id, name, className, value, style)); }
html调用方法:
@Html.SelfDefineTag("p", "test", "test", "test", "p标签", "color:red;background:#ccc;width:100px;text-align:center")
