爲Cs2.0發帖時添加[原創]等前綴

壇裏有人要求(http://online.whpu.edu.cn/Forums) 於是給論壇加了個前綴

代碼如下:

原理很簡單，就不詳述了

 

using CommunityServer.Components;
using CommunityServer.Discussions.Components;

namespace Edot.CSAddOns.Controls
{
    public class PostPrefixList : HtmlSelect 
    {
        TextBox textToPrefix;
        
        /**//// <summary>
        /// 需要綁定的控件
        /// </summary>
        private String _controlToPrefix = null;
        public String ControlToPrefix
        {
            get { return _controlToPrefix; }
            set { _controlToPrefix = value; }
        }

        protected override void OnInit(EventArgs e)
        {
            this.Items.Add("請選擇");
            this.Items.Add("【原創】");
            this.Items.Add("【轉貼】");
            this.Items.Add("【求助】");
            this.Items.Add("【公告】");
            this.Items.Add("【分享】");
            this.Items.Add("【討論】");
            this.Items.Add("【推薦】");
            this.Items.Add("【注意】");
            this.Items.Add("【灌水】");
            this.Items.Add("【已解決】");

            base.OnInit(e);
        }

        protected override void OnPreRender(EventArgs e)
        {
            Page.RegisterClientScriptBlock("AddPrefixForForumPost", GetPrefixScript());

            base.OnPreRender(e);
        }

        protected override void Render(HtmlTextWriter writer)
        {           

            this.Attributes.Add("onchange", "AddPrefix()");           

            base.Render(writer);
        }

        private string GetPrefixScript()
        {
            if (_controlToPrefix == null)
                return null;

            textToPrefix = (TextBox)FindControl(_controlToPrefix);
            string clientId = textToPrefix.ClientID;

            string selectedText = " document.getElementById(/"{0}/").options[document.getElementById(/"{0}/").selectedIndex].text;";

            StringBuilder sb = new StringBuilder();
            sb.Append("<script language=/"javascript/">");
            sb.AppendLine("function AddPrefix(){");

            // 添加內容
            sb.AppendLine("document.getElementById(/"" + clientId + "/").value += " + String.Format(selectedText, this.ClientID) + ";");
            sb.AppendLine("}");
            sb.AppendLine("</script>");

            return sb.ToString();
        }
    }
}
