我正在尝试向搜索框添加建议。用户输入内容后,应该显示建议,如果用户将鼠标悬停在任何建议上,则应突出显示该建议,单击建议时,应将其与分号一起添加到搜索词中以分隔搜索词。
我能够显示建议,但问题是实施以下
预期结果如下
Search box >>> f
suggestions first
four
when first is clicked it will be highlighted then
Search box >>> first;
when t is clicked
Search box >>> first;t
suggestions two
three
click on three will cause to remove the t from search box and add the three
Search box >>> first;three
when tw is entered
Search box >>> first;three;tw
suggestions two
twelve
when two is selected
Search box (first;three;two
proposal.jsp
<c:forEach items="${sug}" var="mysug">
<label id="suggestion" onclick="selectSug(<c:out value="${mysug}"/>)"><c:out
value="${mysug}"/></label>

</c:forEach>
search.jsp
<script type="text/javascript">
function selectSug(value){
alert("vlue"+value);
var temp = document.getElementById("mysearch").textContent ;
document.getElementById("mysearch").textContent = temp + value + " ; ";
}
function findsug(value){
if(window.XMLHttpRequest)
{
xmlhttp = new XMLHttpRequest();
}
else
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if(xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
document.getElementById("sugs").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("get","search?input="+value,false);
xmlhttp.send();
}
...
<s:textfield id="mysearch" name="mysearch" label="Search"
onkeyup="findsug(this.value)"/>
<div id="sugs">
</div>
mystyle.css
#suggestion:hover{
background:red;
}
让我知道是否应包括代码的任何其他部分。
我也想知道是否可以使用jQuery以更简单的方式做到这一点
最佳答案
试试jquery-ui给定的小部件
