Hello i have a dropdown which is fetching data from a database. Forget about the database, i have a text box in front of the dropdown select. The logic is if i type in the text the value should be selected automatically from the dropdown if the value typed in the text not matched with the values in the dropdown, then the user can select the dropdown. Any help would be much appreciated.
Here is my html code!
<div class="form-group">
<label class="col-sm-4 control-label">Scheme**</label>
<div class="col-sm-4">
<select class="form-control" name="scheme" id="scheme">
<?php
for ($column = 'A'; $column <= $lastcol; $column++) {
echo '<option value="' . $column . '">' . $worksheet->getCell($column . '1')->getValue() . '</option>';
}
?>
</select>
</div>
<div class="col-sm-4">
<input type="text" class="form-control" id="txt_scheme" name="txt_scheme" placeholder="Or Type here">
</div>
</div>
In dropdown i m getting these values
QC code
Analyte
Assay Value
Assigned Value
STANDARDDEVIATION
ACCEPTABLEMIN
ACCEPTABLEMAX
Sample ID
Date

check now that values and texts are different and you can even select now by typing one
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#txtselect").keyup(function(){
$("#selbox > option").each(function() {
if($(this).text()==$("#txtselect").val())
{
$(this).attr('selected', 'selected');
}
});
});
});
</script>
</head>
<body>
<select id="selbox">
<option val="select">select</option>
<option val="123">one</option>
<option val="abc">two</option>
<option val="23sfd">three</option>
<option val="27345">four</option>
</select>
<input type="text" id="txtselect"/>
</body>
</html>

Try this
<script type="text/javascript">
function getselected(elem)
{
var textvalue = $(elem).val();
if(textvalue != '')
{
$('select').removeAttr('disabled');
$('select option').removeAttr('selected');
$('select option').each(function(){
if ($(this).html().indexOf(textvalue) > -1)
{
$('select').val($(this).attr('value'));
}
});
}
else
{
$('select').val('');
$('select').attr('disabled','disabled');
}
}
</script>
<input type="text" name="name" value="" onkeydown="getselected(this)">
<select disabled="disabled">
<option value="">Select</option>
<option value="1">QC code</option>
<option value="2">Analyte</option>
<option value="3">Assay Value</option>
<option value="4">Assigned Value</option>
<option value="5">STANDARDDEVIATION</option>
<option value="6">ACCEPTABLEMIN</option>
<option value="7">ACCEPTABLEMAX</option>
<option value="8">Sample ID</option>
<option value="9">Date</option>
</select>

Try this code, then you can modified with your need.
$("#product").on("change keyup paste", function(){
var valuefound ='';
$("#platformid option").each(function(i){
if($(this).text().substring(0, 2).toLowerCase()==$("#product").val().substring(0, 2).toLowerCase() ){ valuefound = $(this).val(); } });
$('option:selected', 'select[name="platformid"]').removeAttr('selected'); $('#platformid option[value="' + valuefound + '"]').prop('selected', true); })

<label for="">Enter Value</label>
<input type="text" class="textVal">
<select name="" id="listItems">
</select>
var listItems = ["One","Two","Three","Four","Five","Six"];
for (var i = 0; i < listItems.length; i++) {
console.log(listItems[i]);
$("#listItems").append("<option>" + listItems[i] + "</option>")
}
$(".textVal").on("focusout",function(){
for (var i = 0; i < listItems.length; i++) {
console.log(listItems[i]);
if(listItems[i] == $(this).val()) {
$("#listItems").val($(this).val());
}
}
})
