javascript
問題：
用戶在 WEB 中輸入 機車 人員 等項 頁面會根據(jù)當(dāng)前字符給出選擇提示
解決：scriptaculous javascript工具包的 Autocompleter.Local
與圖對應(yīng)代碼：
<TD><html:checkbox?property="value(Yloco)"?value="Y"/>機車</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 處理方法
?? var arr = new Array();
?? //關(guān)鍵方法 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 字符數(shù)組 str,str,str.....
????????????var?url?=?"/jczb/jczb/meanwhileDiary.do?method=loco&par="+document.getElementById("loco").value;????
????????????new?Ajax.Request(
