enter text into select object - javascript

I want to enter the text selection for the following select field:
<select name="Payerid" id="Payerid" class="text" name="Payerid">
<option value="383">Aetna Healthcare</option>
...
Using VBA, I know I can use: (If you give me the syntax in another language, I'll convert)
IE.getElementById("Payerid").Value = "383"
but there about 100 options so I don't want to keep track of the values (which are meaningless to me) or changes the website developers make.
So is there a way to enter the text into the select field?
I tried:
IE.getElementById("Payerid").Text = "Aetna Healthcare"
but that didn't work.
Thanks

You mean you want to change the value? That's just $('select').val('value you want');, using Jquery.
If you're wanting to obtain the value based on what is in the text field, that is as below, derived in part from this post.
var pick = "hey";
var value_pick = $('option').filter(function () { return $(this).html() == pick; }).val();
console.log(value_pick);
$("select").val(value_pick);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select>
<option value="1" >hey</option>
<option value="1" >baha</option>
<option value="1" >yo</option>
</select>

How do I populate an html text input field based on an html select option

I'm working on an html page that will allow users to get pre-populated text filled into the text input field, based on the option they select. I'm trying to do this via javascript but I can't get the function to "fire" when I do an onchange within the select input field.
Trying to figure out what I'm doing wrong, either with the function, the innerHTML, or both.
Example code I'm working on below:
HTML
<label for='accountg'>Goal</label>
<select id="accountg" name="accountg" style="border-radius:1px;border:1px solid #003399;font-size:14px;width:50px;" onchange="accountSelect()">
<option value=''></option>
<option value='1'></option>
<option value='2'></option>
<option value='3'></option>
<option value='4'></option>
<option value='5'></option>
</select>
<input type="text" id="account1" name="account1" style="width:900px;" title="140 character maximum" />
JAVASCRIPT
function accountSelect() {
var aSelect = document.getElementById('accountg').value;
var account1 = '';
if(aSelect == '') {
} else if(aSelect == 1){
if(account1 == '')
{
var act1 = 'Outlines written policies and procedures to ensure consistent adherence by staff.';
document.getElementById('account1').innerHTML = act1;
} else {}
}
}
<input> doesn't have an inner content, it has a value though:
document.getElementById('account1').value = act1;

Getting value from select drop-down [duplicate]

Usually I use $("#id").val() to return the value of the selected option, but this time it doesn't work.
The selected tag has the id aioConceptName
html code
<label for="name">Name</label>
<input type="text" name="name" id="name" />
<label for="aioConceptName">AIO Concept Name</label>
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
For dropdown options you probably want something like this:
For selected text
var conceptName = $('#aioConceptName').find(":selected").text();
For selected value
var conceptName = $('#aioConceptName').find(":selected").val();
The reason val() doesn't do the trick is because clicking an option doesn't change the value of the dropdown--it just adds the :selected property to the selected option which is a child of the dropdown.
Set the values for each of the options
<label for="aioConceptName">AIO Concept Name</label>
<select id="aioConceptName">
<option value="0">choose io</option>
<option value="1">roma</option>
<option value="2">totti</option>
</select>
$('#aioConceptName').val() didn't work because .val() returns the value attribute. To have it work properly, the value attributes must be set on each <option>.
Now you can call $('#aioConceptName').val() instead of all this :selected voodoo being suggested by others.
I stumbled across this question and developed a more concise version of Elliot BOnneville's answer:
var conceptName = $('#aioConceptName :selected').text();
or generically:
$('#id :pseudoclass')
This saves you an extra jQuery call, selects everything in one shot, and is more clear (my opinion).
Try this for value...
$("select#id_of_select_element option").filter(":selected").val();
or this for text...
$("select#id_of_select_element option").filter(":selected").text();
If you are in event context, in jQuery, you can retrieve the selected option element using :
$(this).find('option:selected') like this :
$('dropdown_selector').change(function() {
//Use $option (with the "$") to see that the variable is a jQuery object
var $option = $(this).find('option:selected');
//Added with the EDIT
var value = $option.val();//to get content of "value" attrib
var text = $option.text();//to get <option>Text</option> content
});
Edit
As mentioned by PossessWithin, My answer just answer to the question : How to select selected "Option".
Next, to get the option value, use option.val().
Have you considered using plain old javascript?
var box = document.getElementById('aioConceptName');
conceptName = box.options[box.selectedIndex].text;
See also Getting an option text/value with JavaScript
$('#aioConceptName option:selected').val();
For good practice you need to use val() to get value of selected options not text().
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option value="choose">choose io</option>
</select>
You can use
$("#aioConceptName").find(':selected').val();
Or
$("#aioConceptName :selected").val();
Reading the value (not the text) of a select:
var status = $("#Status").val();
var status = $("#Status")[0].value;
var status = $('#Status option:selected').val();
How to disable a select?
in both variants, value can be changed using:
A
User can not interact with the dropdown. And he doesn't know what other options might exists.
$('#Status').prop('disabled', true);
B
User can see the options in the dropdown but all of them are disabled:
$('#Status option').attr('disabled', true);
In this case, $("#Status").val() will only work for jQuery versions smaller than 1.9.0. All other variants will work.
How to update a disabled select?
From code behind you can still update the value in your select. It is disabled only for users:
$("#Status").val(2);
In some cases you might need to fire events:
$("#Status").val(2).change();
With JQuery:
If you want to get the selected option text, you can use $(select element).text().
var text = $('#aioConceptName option:selected').text();
If you want to get selected option value, you can use $(select element).val().
var val = $('#aioConceptName option:selected').val();
Make sure to set value attribute in <option> tag, like:
<select id="aioConceptName">
<option value="">choose io</option>
<option value="roma(value)">roma(text)</option>
<option value="totti(value)">totti(text)</option>
</select>
With this HTML code sample, assuming last option is selected:
var text will give you totti(text)
var val will give you totti(value)
$(document).on('change','#aioConceptName' ,function(){
var val = $('#aioConceptName option:selected').val();
var text = $('#aioConceptName option:selected').text();
$('.result').text("Select Value = " + val);
$('.result').append("<br>Select Text = " + text);
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="aioConceptName">
<option value="io(value)">choose io</option>
<option value="roma(value)">roma(text)</option>
<option value="totti(value)">totti(text)</option>
</select>
<p class="result"></p>
you should use this syntax:
var value = $('#Id :selected').val();
So try this Code:
var values = $('#aioConceptName :selected').val();
you can test in Fiddle: http://jsfiddle.net/PJT6r/9/
see about this answer in this post
to find correct selections with jQuery consider multiple selections can be available in html trees and confuse your expected output.
(:selected).val() or (:selected).text() will not work correct on multiple select options. So we keep an array of all selections first like .map() could do and then return the desired argument or text.
The following example illustrates those problems and offers a better approach
<select id="form-s" multiple="multiple">
<option selected>city1</option>
<option selected value="c2">city2</option>
<option value="c3">city3</option>
</select>
<select id="aioConceptName">
<option value="s1" selected >choose io</option>
<option value="s2">roma </option>
<option value="s3">totti</option>
</select>
<select id="test">
<option value="s4">paloma</option>
<option value="s5" selected >foo</option>
<option value="s6">bar</option>
</select>
<script>
$('select').change(function() {
var a=$(':selected').text(); // "city1city2choose iofoo"
var b=$(':selected').val(); // "city1" - selects just first query !
//but..
var c=$(':selected').map(function(){ // ["city1","city2","choose io","foo"]
return $(this).text();
});
var d=$(':selected').map(function(){ // ["city1","c2","s1","s5"]
return $(this).val();
});
console.log(a,b,c,d);
});
</script>
see the different bug prone output in variant a, b compared to correctly working c & d that keep all selections in an array and then return what you look for.
Just this should work:
var conceptName = $('#aioConceptName').val();
$(function() {
$('#aioConceptName').on('change', function(event) {
console.log(event.type + " event with:", $(this).val());
$(this).prev('input').val($(this).val());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
Using jQuery, just add a change event and get selected value or text within that handler.
If you need selected text, please use this code:
$("#aioConceptName").change(function () {
alert($("#aioConceptName :selected").text())
});
Or if you need selected value, please use this code:
$("#aioConceptName").change(function () {
alert($("#aioConceptName :selected").attr('value'))
});
For anyone who found out that best answer don't work.
Try to use:
$( "#aioConceptName option:selected" ).attr("value");
Works for me in recent projects so it is worth to look on it.
Use the jQuery.val() function for select elements, too:
The .val() method is primarily used to get the values of form elements
such as input, select and textarea. In the case of select elements, it
returns null when no option is selected and an array containing the
value of each selected option when there is at least one and it is
possible to select more because the multiple attribute is present.
$(function() {
$("#aioConceptName").on("change", function() {
$("#debug").text($("#aioConceptName").val());
}).trigger("change");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
<div id="debug"></div>
Straight forward and pretty easy:
Your dropdown
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
Jquery code to get the selected value
$('#aioConceptName').change(function() {
var $option = $(this).find('option:selected');
//Added with the EDIT
var value = $option.val(); //returns the value of the selected option.
var text = $option.text(); //returns the text of the selected option.
});
For get value of tag selected:
$('#id_Of_Parent_Selected_Tag').find(":selected").val();
And if you want to get text use this code:
$('#id_Of_Parent_Selected_Tag').find(":selected").text();
For Example:
<div id="i_am_parent_of_select_tag">
<select>
<option value="1">CR7</option>
<option value="2">MESSI</option>
</select>
</div>
<script>
$('#i_am_parent_of_select_tag').find(":selected").val();//OUTPUT:1 OR 2
$('#i_am_parent_of_select_tag').find(":selected").text();//OUTPUT:CR7 OR MESSI
</script>
You can try to debug it this way:
console.log($('#aioConceptName option:selected').val())
I hope this also helps to understand better and helps
try this below,
$('select[id="aioConceptName[]"] option:selected').each(function(key,value){
options2[$(this).val()] = $(this).text();
console.log(JSON.stringify(options2));
});

If you want to grab the 'value' attribute instead of the text node, this will work for you:
var conceptName = $('#aioConceptName').find(":selected").attr('value');
Here is the simple solution for this issue.
$("select#aioConceptName").change(function () {
var selectedaioConceptName = $('#aioConceptName').find(":selected").val();;
console.log(selectedaioConceptName);
});
try to this one
$(document).ready(function() {
$("#name option").filter(function() {
return $(this).val() == $("#firstname").val();
}).attr('selected', true);
$("#name").live("change", function() {
$("#firstname").val($(this).find("option:selected").attr("value"));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script>
<select id="name" name="name">
<option value="">Please select...</option>
<option value="Elvis">Elvis</option>
<option value="Frank">Frank</option>
<option value="Jim">Jim</option>
</select>
<input type="text" id="firstname" name="firstname" value="Elvis" readonly="readonly">
$('nameofDropDownList').prop('selectedIndex', whateverNumberasInt);
Imagine the DDL as an array with indexes, you are selecting one index. Choose the one which you want to set it to with your JS.
You can use $("#drpList").val();
to fetch a select with same class= name you could do this, to check if a select option is selected.
var bOK = true;
$('.optKategorien').each(function(index,el){
if($(el).find(":selected").text() == "") {
bOK = false;
}
});
I had the same issue and I figured out why it was not working on my case
The html page was divided into different html fragments and I found that I have another input field that carries the same Id of the select, which caused the val() to be always empty
I hope this saves the day for anyone who have similar issue.
Try
aioConceptName.selectedOptions[0].value
let val = aioConceptName.selectedOptions[0].value
console.log('selected value:',val);
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
There is only one correct way to find selected option - by option value attribute. So take the simple code:
//find selected option
$select = $("#mySelect");
$selectedOption = $select.find( "option[value=" + $select.val() + "]" );
//get selected option text
console.log( $selectedOption.text() );
So if you have list like this:
<select id="#mySelect" >
<option value="value1" >First option</option>
<option value="value2" >Second option</option>
<option value="value3" selected >Third option</option>
</select>
If you use selected attribute for option, then find(":selected") will give incorrect result because selected attribute will stay at option forever, even user selects another option.
Even if user will selects first or second option, the result of $("select option:selected") will give two elements! So $("select :selected").text() will give a result like "First option Third option"
So use value attribute selector and don't forget to set value attribute for all options!
You many try this:
var ioConceptName = $('#ioConceptName option:selected').text();

JS: Change select option value on being selected with prompt?

I've looked around and I don't see this being asked before.
I have a select box, like so:
<select onchange="change()">
<option value="" selected>Option 1</option>
<option value="30">Option 2</option>
<option value="90">Option 3</option>
</select>
I want to add another option...
<option value="custom">Option 4</option>
...that when chosen (clicked) an alert box will popup asking the user to type in a number (in the case 30 or 90 weren't viable options, as in the values of the option's) to replace the value of the option.
<script>
function change() {
if(value == "custom") {
value = prompt("Please enter a new number:", "60");
}
}
</script>
I wanted to know what the best way to do this is with plain old javascript - I'll use jQuery if I have to.
Any ideas? An example would be great as well.
Take a look at this code. I think this is what you're trying to do:
HTML
<select id="optionvals" onclick="change()">
<option value="" selected>Option 1</option>
<option value="30">Option 2</option>
<option value="90">Option 3</option>
<option value="custom">Option 4</option>
</select>
JS
function change() {
var oItem = document.getElementById('optionvals');
var value = oItem.options[oItem.selectedIndex].value;
if(value == "custom") {
alert("you've clicked b");
value = prompt("Please enter a new number:", "60");
oItem.options[oItem.selectedIndex].value = value;
console.log(oItem.options[oItem.selectedIndex].value)
}
}
What this does is prompt you on the change only if the selected value in the options is custom. Then after you choose a custom value, it will rewrite the value of that the custom option element to the value you just entered in the prompt. I logged the new value after assigning it to show you that it is working.
Here is a fiddle: https://jsfiddle.net/ng7xvy05/
Your onchange event is the appropriate way to handle this. This is mostly a matter of user interface (UX) design though. To do this in the prompt fashion you ought to use parseFloat:
change() {
var value = prompt('You\'ve chosen Other. Please enter a value', '60');
if(value) {
value = parseFloat(value);
// apply it to your model
} else {
// apply NULL to your model
}
}
From a UXD point of view I would use a typeahead input. It would autosearch known answers but also allow the user to input their own. This is not standard html so you would need to write this yourself or use jquery. But from a user interface design point of view, prompts suck.

make a select dependent with js

I would like to do a select option dependent of another select, i saw there's a way using array with fixed values, but my array is reloaded every time we add a new form field on the form. I would like something like when i select op1, then it just show op1 options on second select.
<select id="id1" name="optionshere">
<option relone="op1">opt one</option>
<option relone="op2">opt two</option>
</select>
<select id="id2" name="resulthere">
<option relone="op1">ans 1 op1</option>
<option relone="op1">ans 2 op2</option>
<option relone="op2">ans 1 op2</option>
</select>
Any idea?
thanks all
Here's a method without jQuery:
When you select an option in the first selectbox, it will hide everything that doesn't match its relone.
var id1 = document.getElementById("id1");
var id2 = document.getElementById("id2");
id1.addEventListener("change", change);
function change() {
for (var i = 0; i < id2.options.length; i++)
id2.options[i].style.display = id2.options[i].getAttribute("relone") == id1.options[id1.selectedIndex].getAttribute("relone") ? "block" : "none";
id2.value = "";
}
change();
<select id="id1" name="optionshere">
<option relone="op1">opt one</option>
<option relone="op2">opt two</option>
</select>
<select id="id2" name="resulthere">
<option relone="op1">ans 1 op1</option>
<option relone="op1">ans 2 op1</option>
<option relone="op2">ans 1 op2</option>
</select>
If Jquery is an option you may go with something like this:
<script type='text/javascript'>
$(function() {
$('#id1').change(function() {
var x = $(this).val();
$('option[relone!=x]').each(function() {
$(this).hide();
});
$('option[relone=x]').each(function() {
$(this).show();
});
});
});
</script>
Then to expand:
There really are many ways in which you can solve this predicament, depending on how variable your pool of answers is going to be.
If you're only interested in using vanilla javascript then let's start with the basics. You're going to want to look into the "onchange" event for your html, so as such:
<select onchange="myFunction()">
Coming right out of the w3schools website, on the Html onchange event attribute:
The onchange attribute fires the moment when the value of the element
is changed.
This will allow you to make a decision based on this element's value. Then inside your js may branch out from here:
You may use Ajax and pass to it that value as a get variable to obtain those options from a separate file.
You may get all options from the second div through a combination of .getElementbyId("id2") and .getElementsByTagName("option") then check for their individual "relone" attribute inside an each loop, and hide those that don't match, and show those that do.
Really, it's all up to what you want to do from there, but I personally would just go for the Jquery approach

Dynamically Change Multiple Hidden Form Fields

I'm somewhat new to jQuery. I'm pretty sure this is possible, but I'm not quote certain how to code this.
What I'm looking to do is to use a dropdown with selections that represent ranges (e.g. if someone were searching for bedrooms, the dropdown selctions would look like "0-2", "3-5", "6+"). Then when someone chooses a selection, two hidden fields would by dynamically filled. One field with the minimum of the range, and the other field with the maximum of the range.
Here is an example of how I'm trying to structure this:
<select id="bedrooms" class="dropdown">
<option>Bedrooms</option>
<option></option>
<option value="1">0-2</option>
<option value="2">3-5</option>
<option value="3">6+</option>
</select>
<input type="hidden" name="bedrooms-from" value=''>
<input type="hidden" name="bedrooms-to" value=''>
I suppose the values of each option could change, I wasn't sure what the best way to approach that would be.
I haven't actually run this, but I think it should work:
$("#bedrooms").change(function ()
{
// Get a local reference to the JQuery-wrapped select and hidden field elements:
var sel = $(this);
var minValInput = $("input[name='bedrooms-from']");
var maxValInput = $("input[name='bedrooms-to']");
// Blank the values of the two hidden fields if appropriate:
if (sel.val() == "") {
minValInput.val("");
maxValInput.val("");
return;
}
// Get the selected option:
var opt = sel.children("[value='" + sel.val() + "']:first");
// Get the text of the selected option and split it on anything other than 0-9:
var values = opt.attr("text").split(/[^0-9]+/);
// Set the values to bedroom-from and bedroom-to:
minValInput.val(values[0]);
maxValInput.val((values[1] != "") ? values[1] : 99999999);
});
$("select").on("change", function() {
$("form").append( /* <input type='hidden'> tag here */ );
});
