How to select dropdown by inserting value in the text box

How to select dropdown by inserting value in the text box - javascript

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

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); })
Working fiddle here https://jsfiddle.net/8xfqeb9y/

<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());
}
}
})

check now that values and texts are different and you can even select now by typing one

You can get the selected option text by using following code.
var country_name = $(this).find('option:selected').text();

SOLUTION:
$(this).children("option:selected").text();

Jquery hide dropdown list not working

Hi I have a small question.
I have 2 select form , and i want when i choose rental the employed type become hidden and here's my code :
<label>Type</label>
<select id="Type-option" class="form-control">
<option value="employed">Employed</option>
<option value="rental">Rental</option>
</select>
<label>Employed Type</label>
<select id="employedType-option" value="employedType-option" class="form-control">
<option value="fulltime">FULLTIME</option>
<option value="parttime">PARTTIME</option>
</select>
$(function() {
var select = $('#Type-option');
select.on('change', function() {
if (select.val() == "rental") {
$('#employedType-option').hide();
} else {
$('#employedType-option').show();
}
});
});
any idea ?

Few suggestions here
1. Never mix your mark up with your javascript.Consider binding events at javascript
2. I have modified your markup a bit,because when you hide employeetype u need to hide the label too
check the following snippet
$(document).ready(function(){
var select = $('#Type-option');
var employeeTypeOption=$('#employedType-option');
var employedType=$('#employedType');
select.on('change', function() {
var selectOption=select.find('option:selected').val();
if (selectOption == "rental") {
employeeTypeOption.hide();
employedType.hide();
} else {
employeeTypeOption.show();
employedType.show();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>Type</label>
<select id="Type-option" class="form-control">
<option value="employed">Employed</option>
<option value="rental">Rental</option>
</select>
<span id="employedType">
<label>Employed Type</label>
<select id="employedType-option" value="employedType-option" class="form-control">
<option value="fulltime">FULLTIME</option>
<option value="parttime">PARTTIME</option>
</select>
</span>
Hope this helps

wrong syntax.
check $(document).on.('action','selection',function(){}); signature.
Tyr with below code
$(document).on('change','#Type-option', function() {
if ($(this).val() == "rental") {
$('#employedType-option').hide();
} else {
$('#employedType-option').show();
}
});

I am not sure but i guess you have missed one of these otherwise your code is working fine
Add reference to jquery library
Wrap your jquery code inside script tag.
<script>
$(function() {
var select = $('#Type-option'); select.on('change', function() {
if (select.val() == "rental") {
$('#employedType-option').hide();
}
else {
$('#employedType-option').show();
}
});
});
</script>

I think this is what you want. try the working demo

How to make one of the selected options in a drop-down list of an HTML form add a text input?

I have the following code:
<label for="city">City</label>
<select id="city" name="city" required>
<option value="">Select city</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
<option value="other" onselect="">Other...</option>
</select>
I would like the form to show a new input text below this drop-down list when user chooses 'other' so that he/she can input his own city. The same way, if the user chooses back one of the existing cities in the drop-down list, the generated text input would disappear.

Add a input after the select and make it as display none
<label for="city">City</label>
<select id="city" name="city" required>
<option value="">Select city</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
<option value="other" onselect="">Other...</option>
</select>
<input id="other" style="display:none" />
and inside the script tag
<script type="text/javascript">
$(document).ready(function () {
$('#city').on('change', function (e) {
var selectValue = this.value;
if (selectValue == "other") {
$("#other").show();
}
else {
$("#other").hide();
}
});
});
</script>
and you also should add Jquery in your html file before the above script tag
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
after combine the Html and Scripts your html file should look like this
<html>
<body>
<label for="city">City</label>
<select id="city" name="city" required>
<option value="">Select city</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
<option value="other" onselect="">Other...</option>
</select>
<input id="other" style="display:none" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#city').on('change', function (e) {
var selectValue = this.value;
if (selectValue == "other") {
$("#other").show();
}
else {
$("#other").hide();
}
});
});
</script>
</body>
</html>

Vadivel's fixed code:
<script type="text/javascript">
$( document ).ready(function() {
$('#city_value').attr('type','hidden');
$('#city').change( function(){
var city=$('#city').val();
if(city=="other")
{
$('#city_value').attr('type','text');
}
else
{
$('#city_value').attr('type','hidden');
}
});
});
</script>

$('#city').live('change', function() {
var selectedCity = $(this).val();
if(selectedCity == "other"){
$('#city').after('<input type="text" id="othercity" name="othercity">');
}else{
$('#othercity').remove():
}
});

JavaScript Code:
function otherOptionCall()
{
var e = document.getElementById("city");
var einput = document.getElementById("inputother");
var strUser = e.options[e.selectedIndex].value;
if(strUser == 2)
{
einput.style.display="block";
}
else
{
einput.style.display="none";
}
}
Html code:
<label for="city">City</label>
<select id="city" name="city" required>
<option value="">Select city</option>
<option value="city1">city1</option>
<option value="city2">city2</option>
<option value="other" onselect="otherOptionCall()">Other...</option>
</select>
<input type="text" name="strother" id="inputother" style="display:none">

Use this code .
this is work fine.
You create this type use Jquery or JavaScript functions
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<body>
<div id=" " style="">
<label for="city">City</label>
<select id="city" name="city" required>
<option value="">Select city</option>
<option value="city1" onselect="city(this.val)">city1</option>
<option value="city2" onselect="city(this.val)">city2</option>
<option value="other" onselect="city(this.val)">Other...</option>
</select>
<input type="text" value="" id="city_value" placeholder="Enter City"/>
</div>
<script type="text/javascript">
$( document ).ready(function() {
$('#city_value').hide();
$('#city').change( function(){
var city=$('#city').val();
if(city=="other")
{
$('#city_value').attr('required',true);
}
else
{
$('#city_value').attr('required',false);
}
});
});
</script> </body>

JQuery convert string to link

I have 3 select fields, and the combined value of these I would like to use as a extra part of an url.
Here's the HTML code:
<select name="cos" id="cos" size="5">
<option value="/squad">Squad</option>
<option value="/class">Class</option>
</select>
<select name="color" id="color" size="5">
<option value="/purpleblack">PurpleBlack</option>
<option value="/redblack">RedBlack</option>
<option value="/aquablack">AquaBlack</option>
</select>
<select name="year" id="year" size="5">
<option value="/1984">1984</option>
<option value="/1985">1985</option>
<option value="/1986">1986</option>
</select>
<br/><br/>
<div id="output"></div>
And the JavaScript:
$("select").change(function () {
var str = "";
$("select option:selected").each(function () {
var id = $(this).parent().attr('name');
str += $(this).attr('value');
});
$("div#output").text(str);
})
.trigger('change');
https://jsfiddle.net/eZKUU/264/
Right now it's working.. after I select an option in all 3 of the selectfields I get an output like /squad/redblack/1985.
I would like to use this output in an url, so it would look like:
mysite.com/squad/redblack/1985
Is there an easy way of doing this? And also.. To only get the link visible after all three of the selectfields have an option selected?

You can use the following. Add an a element and keep it hidden until is completed. Update a element href attribute with selected options:
$("select").change(function() {
var str = "";
$("select option:selected").each(function() {
var id = $(this).parent().attr('name');
str += $(this).attr('value');
//update href with selected values
$("#mySite").attr("href", "mysite.com/" + str);
});
//keep anchor element hidden until all three options is selected
$("#mySite").toggle($("#cos").find("option:selected").length > 0 && $("#color").find("option:selected").length > 0 && $("#year").find("option:selected").length > 0);
$("div#output").text(str);
})
.trigger('change');
#mySite {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="cos" id="cos" size="5">
<option value="/squad">Squad</option>
<option value="/class">Class</option>
</select>
<select name="color" id="color" size="5">
<option value="/purpleblack">PurpleBlack</option>
<option value="/redblack">RedBlack</option>
<option value="/aquablack">AquaBlack</option>
</select>
<select name="year" id="year" size="5">
<option value="/1984">1984</option>
<option value="/1985">1985</option>
<option value="/1986">1986</option>
</select>
<br/>
<br/>
<div id="output"></div>
<a id="mySite" href="#">Redirect Link</a>

You can check to see if the number of selected options is the same amount as the number of select elements.
var selectedAllLength = $("select").length;
$("select").change(function () {
var str = location.origin;
var selected = $("select option:selected");
var selectedCount = selected.length;
if(selectedCount == selectedAllLength) {
selected.each(
function () {
str += $(this).attr('value');
}
);
$("#output").html('<a href=' + str + '>The link is here</a>');
}
})
.trigger('change');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select name="cos" id="cos" size="5">
<option value="/squad">Squad</option>
<option value="/class">Class</option>
</select>
<select name="color" id="color" size="5">
<option value="/purpleblack">PurpleBlack</option>
<option value="/redblack">RedBlack</option>
<option value="/aquablack">AquaBlack</option>
</select>
<select name="year" id="year" size="5">
<option value="/1984">1984</option>
<option value="/1985">1985</option>
<option value="/1986">1986</option>
</select>
<br/><br/>
<div id="output"></div>

To only get the link after all three have been selected, simply use an if statement to only generate and display the link if 3 options are selected. To make it a URL, just append the path you get to the base URL. Something like:
$("select").change(function () {
var str = "";
if(#("select option:selected").length === 3){
$("select option:selected").each(function () {
var id = $(this).parent().attr('name');
str += $(this).attr('value');
});
$("div#output").text("mysite.com" + str);
// Or, if you want a clickable link and not just a URL:
// $("div#output").append($("<a>").attr({href: "mysite.com" + str}).append("Click me"));
}
})
.trigger('change');

Run Javascript if Select values =

I make a script to calculate number.
But i want this script to be work only when user select dropdown to text2 (value=5)
But this script is not working (nothing happened when run the script) :(
Can anyone help or suggest me getting started with this script Please.
<select id="stt" onchange="copy()">
<option value="">Select</option>
<option value="8">text1</option>
<option value="5">text2</option>
<option value="4">text3</option>
</select><br>
Calculate<br>
<input type="text" id="input">
<input type="text" disabled="disabled" id="result">
<script>
function copy() {
if (document.getElementById("stt").value == "5") {
$(document).ready(function(){
$("#input").keyup(function(){
var val1 = +$("#input").val();
$("#result").val(val1*79);
});
});
}
}
</script>

**EDIT**: Changed $("#input").on("change" with $("#input").on("keypress".
New working JSFiddle: http://jsfiddle.net/L69dp/1/
HTML Code:
<select id="stt">
<option value="">
Select
</option>
<option value="8">
text1
</option>
<option value="5">
text2
</option>
<option value="4">
text3
</option>
</select><br>
Calculate<br>
<form>
<input id="input" type="text"> <input disabled="true" id="result" type=
"text">
</form>
JS Code:
$(function() {
function calculate() {
var sttval = $("#stt").val();
if (sttval == "5") {
var val1 = $("#input").val();
$("#result").val(val1 * 79);
} else {
$("#result").val("");
}
}
$("#stt").on("change", function() {
calculate();
});
$("#input").on("keypress", function() {
calculate();
});}());

You need to add a reference to the jquery library:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" ></script>
Put this before your existing script block.
Also, you do not need $(document).ready(function(){} inside the copy() function.

<head>
<script>
var value;
function copy() {
value=document.getElementById("stt").value; //get the value of select everytime it change the value
}
function dd()
{
if(value=="5")//if the value is 5 do the code below
{
var val1= document.getElementById('input');
document.getElementById('result').value=val1.value*79;
}
}
</script>
</head>
<body >
<select id="stt" onchange="copy()">
<option value="">Select</option>
<option value="8">text1</option>
<option value="5">text2</option>
<option value="4">text3</option>
</select><br>
<input type="text" id="input" oninput="dd()" >
<input type="text" disabled="disabled" id="result">
</body>
</html>
