哪位高手来练练手，帮我修改下文本提示框功能。

是不是要这样？var aColors = [{en:"red",cn:"红色"}{en:"green",cn:"绿色"}];
oLi.appendChild(document.createTextNode(the_colors[i].en + " " + the_colors[i].cn));

打个比方，输入r.要求reeed排第一，reed排第二。

存在json里面，上面是我写错了
var aColors = {"color":[{"en":"red","cn":"红色"},{"en":"green","cn":"绿色"}]};
alert(aColors.color[0].en);//red
alert(aColors.color[0].cn);//红色

1.要求指定的文本提示数组排序为第一个和第2个。
如文本框内输入r  要求reeed排第一，reed排第二，其余匹配的数组按原来的排列顺序。
2.在所有提示内容的后面增加不同的内容，
如提示：
red 红色
blue 青色
且新增的内容在点击或选中后不赋值添加到文本框内。<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

为啥reeed排第一，reed第二？根据什么规则来的？

还是打个比方吧，比如输入单个字r的时候在同时很多数组项匹配字母r的时候，
在原有的字母排序前提下，特定一些数组项排在前面，剩余匹配的数组项按原来的字母排序。
如打个 r reeed排第一，reed排第二.其余的rted","rded","raeed","raed"按字母顺序排在后面.......................................................

让reeed，reed，脱离原来的排序功能。

reeed,reed等放在一个数组，
其他一个数组并进行排序
然后第一个数组conat第二个数组
然后显示

差不多了，， -_-!
在帮改下。
var aColors = [{c:"red",n1:"红色1",yx:0},{c:"redd",n1:"红色2",yx:2},{c:"reeed",n1:"红色3",yx:1},{c:"rztd",n1:"红色4",yx:1},{c:"green",n1:"绿色1",yx:1},{c:"blue",n1:"蓝色1",yx:1},{c:"magenta",n1:"洋红色1",yx:1},{c:"yellow",n1:"黄色1",yx:1}];aColors.sort(function(a, b, c) {

return 1;
} else {
if (a.c < b.c < c.c) {
return - 1;
} else {

}
}
}
}
});

还有能在每个数组项前面增加一个字符￥不？
比如我输个r，显示出其中一个reeed。
点击后输出到文本框内为￥reeed。

sort里面的function不要加第三个参数，也不要返回2呀
http://zhaoxunzhiyin.blog.163.com/blog/static/28877742009916114211534/

没办法了嘛？
c:"redd",n1:"红色2",yx:2
我想它排第一个不行吗？
其他的yx:1 yx:0 排后面不行嘛？

能否不那样判断呢？
可否帮我弄了a>b>c>d>e....的循环判断呢？

恩， OK了。
在帮搞个......
能在每个提交到文本框的数组项前面加个字符不？
比如加个￥。
但是在文本提示框中不显示出￥。
只有点击后提交到文本框内才显示出来。
比如点red后在文本框内变成￥red

恩，差不多了。
但又发现点小问题
IE浏览器在鼠标经过中间空白处的时候没有高亮变色。
firefox却在空白处却能高亮。
能有办法让IE兼容不？

不知道你还不会回来看帖呢。
想让你帮我弄下，在输入r的时候能让文本提示框内c:的r变色不？

调试易

哪位高手来练练手，帮我修改下文本提示框功能。
