I want it so that when the DropDown List element is selected, I am able to grab it's value and set the input text, or even a DIV text, or even a label text to the value that was selected. Why doesn't it work? What am I missing?
jsfiddle: https://jsfiddle.net/fob6kp6k/
HTML:
<select id="bonus">
<option value="1">-$5000</option>
<option value="2">-$2500</option>
<option value="3">$0</option>
<option value="4">$1</option>
<option value="5">We really appreciate your work</option>
</select>
<input id="hiddenControl" runat="server" />
JS/JQ:
$(document).ready(function(){
$('#bonus').change(function() {
document.getElementById("hiddenControl").value = $("#bonus option:selected").text());
});
});
whole thing:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$('#bonus').change(function() {
document.getElementById("hiddenControl").value = $("#bonus option:selected").text());
});
});
</script>
</head>
<body>
<select id="bonus">
<option value="1">-$5000</option>
<option value="2">-$2500</option>
<option value="3">$0</option>
<option value="4">$1</option>
<option value="5">We really appreciate your work</option>
</select>
<input id="hiddenControl" runat="server" />
</body>
</html>
Your code has an extra ) in the line where you are setting the value. You need to update from
document.getElementById("hiddenControl").value = $("#bonus option:selected").text());
to
document.getElementById("hiddenControl").value = $("#bonus option:selected").text();
However, as you are using jquery, you should update it further to following
$("#hiddenControl").val($("#bonus option:selected").text());
For reference - http://plnkr.co/edit/3paUZ4wT4GZwZFuCL7Bj?p=preview
You can also make the below changes to make it working
$('#bonus').change(function () {
var text = $("#bonus").find(":selected").text();
$("#hiddenControl").val(text);
});

I have two dropdown menus named date and time respectively. I want to get the
text from the option tag when I click a button, but the javascript function does not seem to work. I 've found similar questions (and answers) about this but nothing worked. The code is below:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function collectData() {
var index = document.getElementById("date").selectedIndex;
var date = document.getElementById("date").options[index].text;
window.alert("You selected: " + date);
}
</script>
</head>
<body>
<select name="date">
<option value="1">date 1</option>
.....
</select>
<select name="time">
<option value="1">time 1</option>
.....
</select>
<button type="button" onclick="collectData()">Get data</button>
</body>
</html>
You're selecting the element by id but you didn't assign the id anywhere.
You need to add the correct id to the item:
<select id="date" name="date">
....
<select id="time" name="time">
Or you could select the items by name:
var index = document.getElementsByName("date")[0].selectedIndex;
Note: getElementsByName returns an array, thats why the [0] was added to select the first item that has that name.
Change code to
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function collectData() {
var e = document.getElementById("date");
var strUser = e.options[e.selectedIndex].value;
window.alert("You selected: " + strUser);
}
</script>
</head>
<body>
<select name="date" id="date">
<option value="1">date 1</option>
..
</select>
<select name="time">
..
</select>
<button type="button" onclick="collectData()">Get data</button>
</body>
</html>
Try this:
function collectData() {
var ddl = document.getElementById("dateSelect");
var text = ddl.options[ddl.selectedIndex].text;
window.alert("You selected: " + text);
}
<select id="dateSelect" name="date">
<option value="1">date 1</option>
<option value="2">date 2</option>
<option value="3">date 3</option>
</select>
<button type="button" onclick="collectData()">Get data</button>
Here a CodePen
you are using getElementById('date').so add id attribute to select element.
I am creating a business options form (rough description I know, but here goes). I want the first select that pops up to be to choose an Entity Type (IE: Corporation, LLC, LLP, etc). Once one of these is chosen, I want to .show() the next form. Here is what I've tried so far:
HTML FILE
<head>
<link rel="stylesheet" type="text/css" href="hide.css">
<script src="//code.jquery.com/jquery-1.10.2.js">
function getEntityType(sel) {
var openingEntityType = sel.value;
$("#basicOpeningEntityInformation").show();
}
</script>
</head>
<body>
<select id="oet" onchange="getEntityType(this)">
<option value="">Select an Option</option>
<option value="inc">Corporation</option>
<option value="llc">Limited Liability Company</option>
<option value="llp">Limited Liability Partnership</option>
<option value="lp">Limited Partnership</option>
<option value="gp">General Partnership</option>
<option value="jv">Joint Venture</option>
<option value="dba">Sole Proprietorship</option>
</select>
<br/>
<br/>
<form id="basicOpeningEntityInformation">
Entity Name:
<input type="text" id="openingEntityName">
<br/>
</form>
</body>
CSS FILE:
#basicOpeningEntityInformation {
display: none;
}
When the page loads, #basicOpeningEntityInformation is hidden. I want it to be unhide when a select from above is chosen. I tested my console and the select is passing it's value to var openingEntityType as it should; however, it is not making the other form visible. I tired with both .basicOpeningEntityInformation and #basicOpeningEntityInformation and neither seem to work (both in the CSS and the Script.
Thank you!
You need to check if the selected value is one of the required values:
$('#oet').on('change', function() {
var selectedItem = $(this).val();
if (selectedItem == 'inc' || selectedItem == 'llc' || selectedItem == 'llp') {
$('#basicOpeningEntityInformation').show();
} else {
$('#basicOpeningEntityInformation').hide();
}
});
Demo: https://jsfiddle.net/tusharj/L4b0wpts/1/
Try adding this..it will work
<head>
<link rel="stylesheet" type="text/css" href="hide.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js"> </script>
<script>
function getEntityType(sel) {
var openingEntityType = sel.value;
jQuery("#basicOpeningEntityInformation").show();
}
</script>
</head>
you are using $(".basicOpeningEntityInformation").show();
so change the
id="basicOpeningEntityInformation" to class="basicOpeningEntityInformation"
OR
$(".basicOpeningEntityInformation").show(); to $("#basicOpeningEntityInformation").show();
I know this is simple, and I need to search in Google. I tried my best and I could not find a better solution. I have a form field, which takes some input and a select field, which has some values. It also has "Other" value.
What I want is:
If the user selects the 'Other' option, a text field to specify that 'Other' should be displayed. When a user selects another option (than 'Other') I want to hide it again. How can I perform that using JQuery?
This is my JSP code
<label for="db">Choose type</label>
<select name="dbType" id=dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>
</select>
<div id="otherType" style="display:none;">
<label for="specify">Specify</label>
<input type="text" name="specify" placeholder="Specify Databse Type"/>
</div>
Now I want to show the DIV tag**(id="otherType")** only when the user selects Other.
I want to try JQuery. This is the code I tried
<script type="text/javascript"
src="jquery-ui-1.10.0/tests/jquery-1.9.0.js"></script>
<script src="jquery-ui-1.10.0/ui/jquery-ui.js"></script>
<script>
$('#dbType').change(function(){
selection = $('this').value();
switch(selection)
{
case 'other':
$('#otherType').show();
break;
case 'default':
$('#otherType').hide();
break;
}
});
</script>
But I am not able to get this. What should I do? Thanks
You have a few issues with your code:
you are missing an open quote on the id of the select element, so: <select name="dbType" id=dbType">
should be <select name="dbType" id="dbType">
$('this') should be $(this): there is no need for the quotes inside the paranthesis.
use .val() instead of .value() when you want to retrieve the value of an option
when u initialize "selection" do it with a var in front of it, unless you already have done it at the beggining of the function
try this:
$('#dbType').on('change',function(){
if( $(this).val()==="other"){
$("#otherType").show()
}
else{
$("#otherType").hide()
}
});
http://jsfiddle.net/ks6cv/
UPDATE for use with switch:
$('#dbType').on('change',function(){
var selection = $(this).val();
switch(selection){
case "other":
$("#otherType").show()
break;
default:
$("#otherType").hide()
}
});
UPDATE with links for jQuery and jQuery-UI:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js"></script>
Demo on JSFiddle
$(document).ready(function () {
toggleFields(); // call this first so we start out with the correct visibility depending on the selected form values
// this will call our toggleFields function every time the selection value of our other field changes
$("#dbType").change(function () {
toggleFields();
});
});
// this toggles the visibility of other server
function toggleFields() {
if ($("#dbType").val() === "other")
$("#otherServer").show();
else
$("#otherServer").hide();
}
HTML:
<p>Choose type</p>
<p>Server:
<select id="dbType" name="dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>
</select>
</p>
<div id="otherServer">
<p>Server:
<input type="text" name="server_name" />
</p>
<p>Port:
<input type="text" name="port_no" />
</p>
</div>
<p align="center">
<input type="submit" value="Submit!" />
</p>
You have to use val() instead of value() and you have missed starting quote id=dbType" should be id="dbType"

Change
selection = $('this').value();
To
selection = $(this).val();
or
selection = this.value;
I got its answer. Here is my code
<label for="db">Choose type</label>
<select name="dbType" id=dbType">
<option>Choose Database Type</option>
<option value="oracle">Oracle</option>
<option value="mssql">MS SQL</option>
<option value="mysql">MySQL</option>
<option value="other">Other</option>
</select>
<div id="other" class="selectDBType" style="display:none;">
<label for="specify">Specify</label>
<input type="text" name="specify" placeholder="Specify Databse Type"/>
</div>
And my script is
$(function() {
$('#dbType').change(function() {
$('.selectDBType').slideUp("slow");
$('#' + $(this).val()).slideDown("slow");
});
});

if(selection == 'other')
{

I want to know how can I get the value of the selected option whenever I change the value combobox. Here's my code:
<html>
<head>
<script type="text/javascript">
function dispOptionValue() {
var select = document.getElementById('footballPlayers');
alert(select.options.value);
}
</script>
</head>
<body>
<select id="footballPlayers" onchange="dispOptionValue">
<option value="1">Ricardo Kaka</option>
<option value="2">Cristiano Ronaldo</option>
<option value="3">Johan Crujjf</option>
<option value="4">Gerd Muller</option>
<option value="5">Franz Beckenbauer</option>
</select>
</body>
</html>
I know its wrong but I don't have any idea how to start. Please help.
You can modify your code as follow:
function dispOptionValue()
{
var select = document.getElementById('footballPlayers');
alert(select.options[select.selectedIndex].value);
}
And change onChange event in dispOptionValue()
try:
<script type="text/javascript">
$(document).ready(function() {
$('input[type=checkbox]').each(function () {
var select = $(this).val();
alert(select);
});
});
</script>
Do not forget to include js file.
I need to make javascript code to swap images with option change.
Here is the code:
<select name="Color:"onchange="document.getElementById('myimage').src = this.value;
">
<option value="images/taylormade_purelite_standbag_bk.jpg">Black/White</option>
<option value="images/taylormade_purelite_standbag_by.jpg">Black/Yellow</option>
<option value="images/taylormade_purelite_standbag_byr.jpg">Black/Yelow/Red</option>
<option value="images/taylormade_purelite_standbag_by.jpg">Black/Yellow</option>
<option value="images/taylormade_purelite_standbag_nr.jpg">Navy/Red</option>
<option value="images/taylormade_purelite_standbag_nw.jpg">Red/Black/White</option>
<option value="images/taylormade_purelite_standbag_rb.jpg">Black/Red</option>
<option value="images/taylormade_purelite_standbag_wrb.jpg">White/Red/Black</option>
</select>
<img src="images/taylormade_purelite_standbag_bk.jpg" id="myimage">
My problem is this: I need to have option values in plain text such as "Black/Yelow/Red" not a URL because this option value will show up in the check out page. Can anybody help me?
Setting up a mapping from your color options to the URLs might work, I think.
<script>
var colorUrlMap = {
"Black/White" : "images/taylormade_purelite_standbag_bk.jpg",
//Add more here
"White/Red/Black" : "images/taylormade_purelite_standbag_wrb.jpg"
};
</script>
<select name="Color:"onchange="document.getElementById('myimage').src = colorUrlMap[this.value];">
<option value="Black/White">Black/White</option>
<!-- Add more here -->
<option value="White/Red/Black">White/Red/Black</option>
</select>
<img src="images/taylormade_purelite_standbag_bk.jpg" id="myimage">
Use another attribute on the option:
<option value="Black/White" rel="images/taylormade_purelite_standbag_bk.jpg">Black/White</option>
Then get that attribute with getAttribute("rel")
<select name="Color:" onchange="document.getElementById('myimage').src = this.options[this.selectedIndex].getAttribute('rel');">
You could use CSS and just change the class based upon the selection. Then all of your URL's are in a stylesheet.
CSS:
.red
{
background: url(red.gif) no-repeat;
}
HTML/JS:
<select name="Color:" onchange="document.getElementById('myimageholder').setAttribute("class", "red");">
This works for me.
<HTML>
<head>
<TITLE>Image Select Test</TITLE>
<script type="text/javascript" language='javascript'>
function flip() {
myimage.src = ColorSelect.children[ColorSelect.selectedIndex].getAttribute('url');
}
</script>
</head>
<body>
<form>
Select an image:<br/>
<select id="ColorSelect" onchange="javascript:flip();">
<option url="images/0.png" value='Zero'>Zero</option>
<option url="images/1.png" value='One'>One</option>
<option url="images/2.png" value='Two'>Two</option>
<option url="images/3.png" value='Three'>Three</option>
<option url="images/4.png" value='Four'>Four</option>
</select>
</form>
<img src="images/unknown.png" id="myimage"/>
</body>
<script type="text/javascript" language='javascript'>
// place this after <body> to run it after body has loaded.
var myimage = document.getElementById('myimage');
var ColorSelect= document.getElementById('ColorSelect');
</script>
</HTML>
ColorSelect.children[ColorSelect.selectedIndex].getAttribute('url'); does not work.
It is rather ColorSelect.options[ColorSelect.selectedIndex].getAttribute('url');
