I have a form which is essentially an autocomplete
input box. I can get this to work perfectly for a single text box. What I need to do is create unique
input boxes by using a php for loop. This will use the counter $i to give each
input box a unique name and id.
The problem is that the unique value of the
input box needs to be passed to the javascript. this will then pass the inputted data to the external php page and return the mysql results.
As mentioned I have this working for a single
input box but need assistance with passing the correct values to the javascript and returning it to correct
input box.
existing code for working solution (first row works only, all other rows update first row
input box)
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function lookup(inputString) {
if(inputString.length == 0) {
// Hide the suggestion box.
$('#suggestions').hide();
} else {
$.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){
if(data.length >0) {
$('#suggestions').show();
$('#autoSuggestionsList').html(data);
}
});
}
} // lookup
function fill(thisValue) {
$('#inputString').val(thisValue);
setTimeout("$('#suggestions').hide();", 200);
}
</script>
</head>
<body>
<form name="form1" id="form1" action="addepartment.php" method="post">
<table>
<? for ( $i = 1; $i <=10; $i++ ) { ?>
<tr>
<td> <? echo $i; ?></td>
<td>
<div>
<input type="text" size="30" value="" id="inputString" onkeyup="lookup(this.value);" onblur="fill();" />
</div>
<div class="suggestionsBox" id="suggestions" style="display: none;">
<img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" />
<div class="suggestionList" id="autoSuggestionsList">
</div>
</div>
</td>
</tr>
<? } ?>
</table>
</body>
</html>
code for autocompleteperson.php is:
$query = $db->query("SELECT fullname FROM Persons WHERE fullname LIKE '$queryString%' LIMIT 10");
if($query) {
while ($result = $query ->fetch_object()) {
echo '<li onClick="fill(\''.$result->fullname.'\');">'.$result->fullname.'</li>';
}
}
in order to get it to work for all rows, I include the counter $i in each of the file names as below:
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function lookup(inputString<? echo $i; ?>) {
if(inputString<? echo $i; ?>.length == 0) {
// Hide the suggestion box.
$('#suggestions<? echo $i; ?>').hide();
} else {
$.post("autocompleteperson.php", {queryString: ""+inputString<? echo $i; ?>+""}, function(data){
if(data.length >0) {
$('#suggestions<? echo $i; ?>').show();
$('#autoSuggestionsList<? echo $i; ?>').html(data);
}
});
}
} // lookup
function fill(thisValue) {
$('#inputString<? echo $i; ?>').val(thisValue);
setTimeout("$('#suggestions<? echo $i; ?>').hide();", 200);
}
</script>
</head>
<body>
<form name="form1" id="form1" action="addepartment.php" method="post">
<table>
<? for ( $i = 1; $i <=10; $i++ ) { ?>
<tr>
<td> <? echo $i; ?></td>
<td>
<div>
<input type="text" size="30" value="" id="inputString<? echo $i; ?>" onkeyup="lookup(this.value);" onblur="fill();" />
</div>
<div class="suggestionsBox" id="suggestions<? echo $i; ?>" style="display: none;">
<img src="upArrow.png" style="position: relative; top: -12px; left: 20px;" alt="upArrow" />
<div class="suggestionList" id="autoSuggestionsList<? echo $i; ?>">
</div>
</div>
</td>
</tr>
<? } ?>
</table>
</body>
</html>
The autocomplete suggestion works (although always shown on first row) but when selecting the data always returns to row 1, even if
input was on row 5. I have a feeling this has to do with the fill() but not sure? is it due the the autocomplete page code? or does the fill referencing ThisValue have something to do with it.
example of this page (as above) can be found here
Thanks for the assistance, much appreciated.
UPDATE - LOLO
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function lookup(i, inputString) {
if(inputValue.length == 0) {
// Hide the suggestion box.
$('#suggestions' + i).hide();
} else {
$.post("autocompleteperson.php", {queryString: ""+inputString+""}, function(data){
if(data.length >0) {
$('#suggestions' + i).show();
$('#autoSuggestionsList' + i).html(data);
}
});
}
} // lookup
function fill(i, thisValue) {
$('#inputString' + i).val(thisValue);
setTimeout("$('#suggestions' + i).hide();", 200);
}
</script>
