以下是我在 div 中显示匹配的用户输入但我想在用户输入不匹配时隐藏 div 的代码。我似乎无法使用以下代码来做到这一点:
HTML 代码:
<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />
<div id="lc"> <p id='placeholder'> </p> </div>
JS代码:
// JavaScript Document
s1= new String()
s2= new String()
var myArray = new Array();
myArray[0] = "Football";
myArray[1] = "Baseball";
myArray[2] = "Cricket";
myArray[3] = "Hockey";
myArray[4] = "Basketball";
myArray[5] = "Shooting";
function test()
{
s1 = document.getElementById('filter').value;
var myRegex = new RegExp((s1),"ig");
arraysearch(myRegex);
}
function arraysearch(myRegex)
{
document.getElementById('placeholder').innerHTML="";
for(i=0; i<myArray.length; i++)
{
if (myArray[i].match(myRegex))
{
document.getElementById('lc').style.visibility='visible';
document.getElementById('placeholder').innerHTML += myArray[i] + "<br/>";
}
else
{
document.getElementById('lc').style.visibility='hidden';
}
}
}
