Js实现带自动提示的文本框效果

分享二个自动提示的文本框效果的js实现代码。

例一，直接编写AJAX 实现。 客户端：

服务器端（9-10.aspx ）：

2. <%@ Page Language="C#" ContentType="text/html" ResponseEncoding="gb2312" %>
3. <%@ Import Namespace="System.Data" %>
4. <%
5. Response.CacheControl = "no-cache";
6. Response.AddHeader("Pragma","no-cache");
7. string sInput = Request["sColor"].Trim();
8. if(sInput.Length == 0)
9. return;
10. string sResult = "";
11. string[] aColors = new string[]{"aliceblue","antiquewith","aquamarine","azure","beige","bisque","black","blanchedalmond","blue","blueviolet","brass",
12. "bronze","brown","burlywood","cadetblue","chartreuse","chocolate","copper","coral","cornfloewrblue","cornsilk","cyan",
13. "darkblue","darkcyan","darkgoldenrod","darkgray","darkgreen","darkhaki","darkmagenta","darkolivegreen","darkorchid",
14. "darkorenge","darkred","darksalmon","darkseagreen","darkslateblue","darkslategray","darkturquoise","darkviolet","deeppink",
15. "deepskyblue","dimgray","dodgerblue","feldspar","firebrick","floralwhite","forestgreen","fuchsia","gainsboro","gold","goldenrod",
16. "golenrod","gostwhite","gray","green","greenyellow","honeydew","hotpink","indianred","inen","ivory","khaki","lavender",
17. "lavenderblush","lawngreen","lemonchiffon","lightblue","lightcoral","lightcyan","lightgodenrod","lightgodenrodyellow","lightgray",
18. "lightgreen","lightpink","lightsalmon","lightseagreen","lightskyblue","lightslateblue","lightslategray","lightsteelblue","lightyellow",
19. "lime","limegreen","magenta","magenta","maroom","maroon","mediumaquamarine","mediumblue","mediumorchid","mediumpurpul",
20. "mediumseagreen","mediumslateblue","mediumspringgreen","mediumturquoise","mediumvioletred","midnightblue","mintcream",
21. "mistyrose","moccasin","navajowhite","navy","navyblue","oldlace","olivedrab","orange","orchid","orengered","palegodenrod",
22. "palegreen","paleturquoise","palevioletred","papayawhip","peachpuff","peru","pink","plum","powderblue","purple","quartz","red",
23. "rosybrown","royalblue","saddlebrown","salmon","sandybrown","scarlet","seagreen","seashell","sienna","silver","skyblue","slategray",
24. "snow","springgreen","steelblue","tan","thistle","tomato","turquoise","violet","violetred","wheat","whitesmoke","yellow","yellowgreen"};
25. for(int i=0;iif(aColors[i].IndexOf(sInput) == 0)
26. sResult += aColors[i] + ",";
27. }
28. if(sResult.Length>0) //如果有匹配项
29. sResult = sResult.Substring(0,sResult.Length-1); //去掉最后的“,”号
30. Response.Write(sResult);
31. %>

例二，使用jQuery 实现。 客户端：

服务器端（14-10.aspx ）：

2. <%@ Page Language="C#" ContentType="text/html" ResponseEncoding="gb2312" %>
3. <%@ Import Namespace="System.Data" %>
4. <%
5. Response.CacheControl = "no-cache";
6. Response.AddHeader("Pragma","no-cache");
7. string sInput = Request["sColor"].Trim();
8. if(sInput.Length == 0)
9. return;
10. string sResult = "";
11. string[] aColors = new string[]{"aliceblue","antiquewith","aquamarine","azure","beige","bisque","black","blanchedalmond","blue","blueviolet","brass","bronze",
12. "brown","burlywood","cadetblue","chartreuse","chocolate","copper","coral","cornfloewrblue","cornsilk","cyan","darkblue","darkcyan",
13. "darkgoldenrod","darkgray","darkgreen","darkhaki","darkmagenta","darkolivegreen","darkorchid","darkorenge","darkred","darksalmon",
14. "darkseagreen","darkslateblue","darkslategray","darkturquoise","darkviolet","deeppink","deepskyblue","dimgray","dodgerblue",
15. "feldspar","firebrick","floralwhite","forestgreen","fuchsia","gainsboro","gold","goldenrod","golenrod","gostwhite","gray","green",
16. "greenyellow","honeydew","hotpink","indianred","inen","ivory","khaki","lavender","lavenderblush","lawngreen","lemonchiffon",
17. "lightblue","lightcoral","lightcyan","lightgodenrod","lightgodenrodyellow","lightgray","lightgreen","lightpink","lightsalmon",
18. "lightseagreen","lightskyblue","lightslateblue","lightslategray","lightsteelblue","lightyellow","lime","limegreen","magenta",
19. "magenta","maroom","maroon","mediumaquamarine","mediumblue","mediumorchid","mediumpurpul","mediumseagreen",
20. "mediumslateblue","mediumspringgreen","mediumturquoise","mediumvioletred","midnightblue","mintcream","mistyrose",
21. "moccasin","navajowhite","navy","navyblue","oldlace","olivedrab","orange","orchid","orengered","palegodenrod","palegreen",
22. "paleturquoise","palevioletred","papayawhip","peachpuff","peru","pink","plum","powderblue","purple","quartz","red","rosybrown",
23. "royalblue","saddlebrown","salmon","sandybrown","scarlet","seagreen","seashell","sienna","silver","skyblue","slategray","snow",
24. "springgreen","steelblue","tan","thistle","tomato","turquoise","violet","violetred","wheat","whitesmoke","yellow","yellowgreen"};
25. for(int i=0;iif(aColors[i].IndexOf(sInput) == 0)
26. sResult += aColors[i] + ",";
27. }
28. if(sResult.Length>0) //如果有匹配项
29. sResult = sResult.Substring(0,sResult.Length-1); //去掉最后的“,”号
30. Response.Write(sResult);
31. %>
