页面版文本框智能提示JS代码_javascript技巧

于是这code便诞生了，如下：

";
tempDiv[sumSearchCount]=i;
sumSearchCount++;
}
}
div_show.innerHTML=row;
}
else if(objTxt.value.length==0 || objTxt.value == null)
{
var div_msg = document.getElementById("divMsg");
div_msg.style.display="none";
div_msg.innerHTML="";
}
}
//提示内容单击保存到文本框中
function span_click(sp)
{
clear();
objTxt.value=sp.innerHTML;
document.getElementById("DropDownList1").options[sp.id.substring(sp.id.indexOf('_')+1,sp.id.length)].selected="selected";
}
//停止查询，关闭提示
function closeSearch()
{
var tbl = document.activeElement.parentElement;
if(tbl && tbl.id!="divMsg")//防止使用上下键后丢失提示内容
{
clear();
document.getElementById("divMsg").innerHTML="";
}
else if(currentIndex==-1)
{
clear();
document.getElementById("divMsg").innerHTML="";
}
}
//清空提示
function clear()
{
fnStopInterval();
currentIndex=-1;
tempValue="";
document.getElementById("divMsg").style.display="none";
}
//使用键盘上下方向键和enter键
function changeSelect()
{
var divContent = document.getElementById("divMsg");
if(divContent && divContent.style.display=="block")
{
if (event.keyCode == 38 || event.keyCode == 40 || event.keyCode == 13)
{
if(currentIndex!=-1) document.getElementById("divsearch_"+tempDiv[currentIndex]).style.backgroundColor="";
if (event.keyCode == 38 && currentIndex > 0)
{
currentIndex--;
document.getElementById("divsearch_"+tempDiv[currentIndex]).style.backgroundColor="#3366CC";
}
else if (event.keyCode == 40 && currentIndex {
currentIndex++;
document.getElementById("divsearch_"+tempDiv[currentIndex]).style.backgroundColor="#3366CC";
}
else if (event.keyCode == 13)
{
if(currentIndex > -1)
{
var divpart = document.getElementById("divsearch_"+tempDiv[currentIndex]);
objTxt.value=divpart.innerHTML;
document.getElementById("DropDownList1").options[tempDiv[currentIndex]].selected="selected";
clear();
}
}
}
}
}
