添加表情的代碼

先在網(wǎng)上找到附件中的素材和部分源碼，在稍加改造即可應(yīng)用于評(píng)論框或者留言框旁邊

 

 

下面代碼和網(wǎng)上下載的素材是不一樣的，素材中的是html控件，而下面則改成了服務(wù)器控件（為了能在后臺(tái)獲取文本框的值），先上代碼，改動(dòng)說明下面再說：

原素材是獲取name，而服務(wù)器控件沒有name，故我們改成獲取id

即將onClick="document.forms[0].gb_word.value（這句看不懂沒有關(guān)系，是素材中的）改成

Html代碼
  1. onClick="document.getElementById('txtname').value  

注：txtname為文本框的id值

 

這樣就能在.cs文件中能取得文本框的值，從而添加到數(shù)據(jù)庫中

 

注：服務(wù)器控件的id轉(zhuǎn)成html的id后是一段很長(zhǎng)的字符串，如果上面改動(dòng)不能用，就把txtname改成對(duì)應(yīng)生成的html頁面的id即可

 

到此為止，展示頁面的代碼就改完了，接下來在后面進(jìn)行處理，主要用到了replace（用法在網(wǎng)上搜一下就知道了，非常好用的）函數(shù)。

 

符號(hào)裝成圖片的方法

C#代碼
  1. public string PictureSwap(string str)   
  2.    {   
  3.        string[] a = new string[] { "[-_-]", "[@o@]", "[-|-]", "[o_o]", "[ToT]", "[*_*]", "[-x-]", "[-_-zz]", "[t_t]", "[-_-!]", "[:,]", "[:P]", "[:D]", "[:)]", "[:(]", "[:O]", "[:#]", "[:Z]", "[:0=]", "[/:P]", "[:$]", "[-.-]", "[/-_-]", "[:{]", "[zz]", "[|-_-|]", "[-_-||]", "[:.]", "[:-Q]", "[9_9]", "[:,.]", "[:?]", "[:-|]", "[:K]", "[:G]", "[:L]", "[:c]", "[:q]", "[:Y]", "[/gs]", "[/sg]", "[/hp]", "[/ok]", "[/rain]", "[/yin]" };   
  4.        for (int i = 1; i <= 45; i++)   
  5.        {   
  6.            str = str.Replace(a[i - 1], "<img src='../images/" + i + ".gif' width='20' height='20'/>");   
  7.              
  8.        }   
  9.        Response.Write(str + "asadadadad<br/>");   
  10.        return str;   
  11.    }  

 參數(shù)str為要要轉(zhuǎn)換的文字，比如說是整個(gè)留言的內(nèi)容（其中加有類似（[-|-]）的符號(hào)）

 

用到了數(shù)組跟循環(huán)，也不太難就不說了

 

調(diào)用方法

Java代碼
  1. string s = PictureSwap(txtname.Text.toString());  
 

s即為轉(zhuǎn)換后的能顯示圖片的字符串

 

顯示時(shí)有兩種處理方式：

1.在存入數(shù)據(jù)庫之前調(diào)用PictureSwap改變成圖片地址

2、取出數(shù)據(jù)時(shí)調(diào)用PictureSwap轉(zhuǎn)換成圖片顯示

 

這就看個(gè)人愛好，也看是哪一個(gè)使用頻繁咯。
