我正在尝试根据用户的输入自动完成以选择选项
就像是
<input type=text onkeyup=findit()>
<select id="sel">
<option value="s0001">Adams</option>
<option value="s0002">Alder</option>
.
.
.
<select>
我找到了这段代码'但它只适用于页面中的一个选择(我需要多选)
<html>
<head>
<script type="text/javascript">
//initialize some global variables
var list = null;
function fillit(sel,fld) {
var field = document.getElementById("entry");
var selobj = document.getElementById("sel");
if(!list)
{
var len = selobj.options.length;
field.value = "";
list = new Array();
for(var i = 0;i < len;i++)
{
list[i] = new Object();
list[i]["text"] = selobj.options[i].text;
list[i]["value"] = selobj.options[i].value;
}
}
else
{
var op = document.createElement("option");
var tmp = null;
for(var i = 0;i < list.length;i++)
{
tmp = op.cloneNode(true);
tmp.appendChild(document.createTextNode(list[i]["text"]));
tmp.setAttribute("value",list[i]["value"]);
selobj.appendChild(tmp)/*;*/
}
}
}
function findIt(sel,field)
{
var selobj = document.getElementById("sel");
var d = document.getElementById("display");
var len = list.length;
if(field.value.length > 1)
{
if(!list)
{
fillit(sel,field);
}
var op = document.createElement("option");
selobj.options.length = 1
var reg = new RegExp(field.value,"i");
var tmp = null;
var count = 0;
var msg = "";
for(var i = 0;i < len;i++)
{
if(reg.test(list[i].text))
{
// d.childNodes[0].nodeValue = msg;
tmp = op.cloneNode(true);
tmp.setAttribute("value",list[i].value);
tmp.appendChild(document.createTextNode(list[i].text));
selobj.appendChild(tmp);
}
}
}
else if(list && len > selobj.options.length)
{
selobj.selectedIndex = 0;
fillit(sel,field);
}
}
</script>
</head>
<body onLoad="fillit(sel,entry)">
<div>Enter the first three letters of a street and select a match from the menu.</div>
<form>
Street
<input type="text" name="Street" id="entry" onKeyUp="findIt(sel,this)"><br>
<select id="sel">
<option value="s0001">Adams</option>
<option value="s0002">Alder</option>
<option value="s0003">bol</option>
<option value="s0004">col</option>
<option value="s0005">dol</option>
<option value="s0007">Cooper</option>
<!--and so on and so forth-->
</select>
</form>
</body>
任何想法如何使它在页面上的多选上工作?
谢谢
