Problem in onkeyup event

[newphpcoder]

Hi...

i got problem in using this code:

<script>
 window.onload = function() { 
  var ul = document.getElementById('searchpayroll');
  var links = ul.getElementsByTagName('a');
  var i = 0;
 
 document.onkeyup = function(e){ 
  
 e = window.event || e;
   
   var key = e.charCode || e.keyCode;

      if (key == 40) { 
      // up pressed
      if (i < links.length - 1) i++; 
    }
    else if (key == 38) {
      // down pressed
      if (i > 0) i--;
    }
    // focus on link
    
    
   links[i].focus();
   
    // request content in here for link with ajax
   // alert(links[i].href);
  }
}
</script>
<div id="Search">
<form>
<p class="serif"><b>Search Lastname:</b></p>
<input type="text" name="search_" size="20" onkeyup="searchemppay(this.value);">
<!--<div id="searchpayroll" style="overflow:auto; height:390px; width:auto; margin-left:2px" >-->
<hr />
<ul id="searchpayroll" style="overflow:auto; height:385px; width:auto; margin-left:2px;">
<!--<ul>-->
{section name=co_emp loop=$personalAll}
<!--<li onclick="changeEmployeePay('{$personalAll[co_emp].EMP_ID}')">{$personalAll[co_emp].FULLNAME}</li> -->
<li><a href="SearchData.php?queryEmpID={$personalAll[co_emp].EMP_ID}">{$personalAll[co_emp].FULLNAME}</a></li>
<hr />
{sectionelse}
<li>No records found</li>
{/section}
</ul>
</div>

the problem is...when I type in search textfield it focus in the name list..like for example i type a after I press a it was focus in the firstname, which is wrong..

I think it cause from the javascript code..

I want to happen is i continue typing in search textfield.

Thank you

where is the searchemppay() function?

[newphpcoder]

here is the javascript:

<script>
function searchemppay(queryString) {
  //alert(queryString);
    
    var ajaxRequest = remoteRequestObject();
    ajaxRequest.onreadystatechange = function() {
        if (ajaxRequest.readyState == 4 && ajaxRequest.status == 200) {
            var result = ajaxRequest.responseText;
            //alert(result);
            document.getElementById('searchpayroll').innerHTML = result;
        } 
    }
    var url = "search.php?query=" + queryString; 
    ajaxRequest.open("GET", url, true);
    ajaxRequest.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
    ajaxRequest.send(null);

}

function changeEmployeePay(queryID) {
window.location = "SearchData.php?queryEmpID=" + queryID;
}
</script>

search.php

<?php
    
session_start();
include 'config.php';

$queryString = $_GET["query"];


if ($queryString == "" || $queryString == null) {

$sql = "SELECT EMP_ID, CONCAT(LNAME, ', ',  FNAME, ' ', MI, '.') AS FULLNAME FROM PERSONAL 
        ORDER BY FULLNAME ASC";
}
else {
$sql = "SELECT EMP_ID, CONCAT(LNAME, ', ',  FNAME, ' ', MI, '.') AS FULLNAME FROM PERSONAL WHERE LNAME LIKE '" . $queryString . "%' ORDER BY FULLNAME ASC";
}

$recPersonalQuery = $conn->Execute($sql);
if (!$recPersonalQuery->BOF) {
    $recPersonalQuery->MoveFirst();
}

echo "<hr />";
echo "<ul id='searchpayroll'>";

while (!$recPersonalQuery->EOF) {

    $empID   = $recPersonalQuery->fields["EMP_ID"]; 
    $empFullName = $recPersonalQuery->fields["FULLNAME"];

    //echo "<li onclick=changeEmployeePay('$empID'); style= 'font-family:'Times New Roman',Times,serif; font-size:10%;'>$empFullName</li>";
    echo "<a href='SearchData.php?queryEmpID=$empID'; style= 'font-family:'Times New Roman',Times,serif; font-size:10%;'>$empFullName</li>";
    echo "<hr />";
    $recPersonalQuery->MoveNext();
} 
echo "</ul>";

$recPersonalQuery->Close();

exit();    
    
?>

SearchData.php

<?php
session_start();

$queryStr = trim($_GET["queryEmpID"]);

$_SESSION['empID'] = $queryStr; 

session_write_close();
header("Location:DisplayEmpPayroll.php");
exit();
?>

Thank you so much..

my problem is in typing textarea...I think it cause from my script in keycode for up and down?

[newphpcoder]

Before I used this script for up and down key in choosing employee name I don't have problem in searching employee name:

<script>
 window.onload = function() { 
  var ul = document.getElementById('searchpayroll');
  var links = ul.getElementsByTagName('a');
  var i = 0;
 
 document.onkeyup = function(e){ 
  
 e = window.event || e;
   
   var key = e.charCode || e.keyCode;

      if (key == 40) { 
      // up pressed
      if (i < links.length - 1) i++; 
    }
    else if (key == 38) {
      // down pressed
      if (i > 0) i--;
    }
    // focus on link
    
    
   links[i].focus();
   
    // request content in here for link with ajax
   // alert(links[i].href);
  }
}
</script>

Thank you...

I tried to edit that code but I the key event didi not work...

I don't know how can i figured out..

[newphpcoder]

I have no idea on what should I need to change in my script for onkeyup so that my search will work again..

Thank you so much..

The simplest thing is to only focus if it's an up or down keypress.

if (key == 40 || key == 38) {
   links[i].focus();
}

[newphpcoder]

when i edit my code:

<script>
window.onload = function() {   
// function() { 
  var ul = document.getElementById('searchpayroll');
  var links = ul.getElementsByTagName('a');
  var i = 0;
 
 document.onkeyup = function(e){ 
  //function(e){    
 e = window.event || e;
 // e = e;     
    
   var key = e.charCode || e.keyCode;
   
   /*if (key == 40 || key == 38) {
   links[i].focus();
   } */

    //if (key == 38) {
    /* if (key == 40) { 
      // up pressed
      //if (i < links.length - 1) i++;
      if (i < links.length - 1) i++; 
        links[i].focus();    
    }
    else if (key == 38) {
      // down pressed
      if (i > 0) i--;
      links[i].focus(); 
     // if (i < 0) i++; 
    }
    // focus on link
    
    // request content in here for link with ajax
   // alert(links[i].href);  */

}
}
</script>

the up and down key did not work, it was always in the first employee name..:(


Thank you

[newphpcoder]

Now, i fix it using this code:

<script>
window.onload = function() {   
// function() { 
  var ul = document.getElementById('searchpayroll');
  var links = ul.getElementsByTagName('a');
  var i = 0;
 
 document.onkeyup = function(e){ 
  //function(e){    
 e = window.event || e;
 // e = e;     
    
   var key = e.charCode || e.keyCode;
   
   /*if (key == 40 || key == 38) {
   links[i].focus();
   }  */

    //if (key == 38) {
     if (key == 40) { 
      // up pressed
      //if (i < links.length - 1) i++;
      if (i < links.length - 1) i++; 
        links[i].focus();    
    }
    else if (key == 38) {
      // down pressed
      if (i > 0) i--;
      links[i].focus(); 
     // if (i < 0) i++; 
    }
    // focus on link
    
    // request content in here for link with ajax
   // alert(links[i].href);  */

}
}
</script>
<div id="Search">
<form>
<p class="serif"><b>Search Lastname:</b></p>
<input type="text" name="search_" size="20" onkeyup="searchemppay(this.value);">
<!--<div id="searchpayroll" style="overflow:auto; height:390px; width:auto; margin-left:2px" >-->
<hr />
<ul id="searchpayroll" style="overflow:auto; height:385px; width:auto; margin-left:2px;">
<!--<ul>-->
{section name=co_emp loop=$personalAll}
<!--<li onclick="changeEmployeePay('{$personalAll[co_emp].EMP_ID}')">{$personalAll[co_emp].FULLNAME}</li> -->
<li><a href="SearchData.php?queryEmpID={$personalAll[co_emp].EMP_ID}">{$personalAll[co_emp].FULLNAME}</a></li>
<hr />
{sectionelse}
<li>No records found</li>
{/section}
</ul>
</div>
