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 ）：

Response.CacheControl = "no-cache";
Response.AddHeader("Pragma","no-cache");
string sInput = Request["sColor"].Trim();
if(sInput.Length == 0)
return;
string sResult = "";
string[] aColors = new string[]{"aliceblue","antiquewith","aquamarine","azure","beige","bisque","black","blanchedalmond","blue","blueviolet","brass",
"bronze","brown","burlywood","cadetblue","chartreuse","chocolate","copper","coral","cornfloewrblue","cornsilk","cyan",

for(int i=0;iif(aColors[i].IndexOf(sInput) == 0)
sResult += aColors[i] + ",";
}
if(sResult.Length>0) //如果有匹配项
sResult = sResult.Substring(0,sResult.Length-1); //去掉最后的“,”号
Response.Write(sResult);
%>

复制代码

例二，使用jQuery 实现。客户端：

jQuery实现自动提示的文本框
oColorsUl.find("li").click(function(){
oInputField.val($(this).text());
clearColors();
}).hover(
function(){$(this).addClass("mouseOver");},
function(){$(this).removeClass("mouseOver");}
);
}
function findColors(){
initVars(); //初始化变量
if(oInputField.val().length > 0){
//获取异步数据
$.get("14-10.aspx",{sColor:oInputField.val()},
function(data){
var aResult = new Array();
if(data.length > 0){
aResult = data.split(",");
setColors(aResult); //显示服务器结果
} bbs.it-home.org
else
clearColors();
});
}
else
clearColors(); //无输入时清除提示框（例如用户按del键）
}
Color:
