javascript
问题：
用户在 WEB 中输入 机车 人员 等项 页面会根据当前字符给出选择提示
解决：scriptaculous javascript工具包的 Autocompleter.Local
与图对应代码：
<TD><html:checkbox property="value(Yloco)" value="Y"/>机车</TD>
<TD><input id="loco" type="text" name="value(loco)" size="20" value="${map['loco']}" onkeyup="getData();"></TD>
<div id="locoupdate" style="display:none;border:1px solid black;background-color:white;height:150px;overflow:auto;"></div>
javascript 处理方法
var arr = new Array();
//关键方法 scriptaculous框架 提供方法
//要使用 此方法 先到入 prototype.js effects.js controls.js
new Autocompleter.Local('loco','locoupdate',
arr, { tokens: new Array(',','\n'), fullSearch: true, partialSearch: true});
function getData(){
//得到 字符数组 str,str,str.....
var url = "/jczb/jczb/meanwhileDiary.do?method=loco&par="+document.getElementById("loco").value;
new Ajax.Request(
url,
{
method: 'get',
onComplete: action
});
}
function action(req){
var str = req.responseText.split(",") ;
while(!arr.length==0){
arr.pop();
}
for( var jj=0;jj<str.length-1;jj++ ){
arr[jj] = str[jj];
}
}
