I have 6 select fields to select three different options ("Please Select..", "Yes" and "No"). I want to be able to know which values has been selected inside a group, each group of select is inside a div. I try using this:
$('#qqq').find('select').change(function () {
// alert($(this).val());
var option = $(this).val();
selectValues.push($(this).val());
But this only works when you change the value, and don´t storage the values, therefore if you go through the group in other order the results are different. For example if you start in the last select and then go in inverse order. Pushing the values into a variable, the values are saved but if you change twice is saved it twice in "selectValues"
My html is something like this:
<div class="mygroup">
<select id="aa">
<select id="bb">
<select id="cc">
</div>
The values of the select are generated in jQuery, therefore the values can be retrieve using --> this.val()
My question is how can I retrieve the values of a group and then go through it? I had though in save it in an array and then go through it, but I don't know if the array values are going to change when you change the select twice.
I want to know it, because if any of the select is "Yes", some below input fields should be required and if all of them are "No", those fields should be readonly.
Like this:
var curVals = {};
$('#qqq').find('select').each(function () {
curVals[$(this).prop('id')] = $(this).val();
});
or this:
var $selectedYes = $('#qqq').find('select').filter(function () {
return $(this).val().toLowerCase() === 'yes';
});
If any have 'Yes' then $selectedYes will be a jQuery object containing only those select element(s); if none are, it will be an empty jQuery object.

I have a form that has 3 drop downs to make selections, the first drop down allows the user to select a specific Type, the second box, the user must select a date which will then present users with the filtered options on the 3rd drop down which is done in Jquery. I had it working where the user only selects one option in the 3rd drop down.
Now I would like the user to select multiple options. The code below is what I used to get the single selection to update the hidden field and pass via form submission.
The below code minus the ".join('|')" outputs the values into the hidden field then it gets passed into a data storage via POST.
This is my code:
$('#TopicID').on('change',function()
{ TIDval.val( $(this).find(':selected').text().join('|') );
});
I tried several versions to get it to work if I remove the ".join('|')" the output gives me all of the values concatenated.
Value 1: tree
Value 2: boat
Value 3: car
The output is as follows: treeboatcar
but I need: tree|boat|car
I have updated my new code to reflect the solution suggested by Loading... in this thread to the following.
$('#TopicID').change(function(){
var selectedText = $(this).find(':selected').map(function(){
return $(this).text(); //$(this).val()
}).get().join('|');
$("#TopicID_value").text(selectedText);
});
Which now updates the hidden field value correctly with the pipe separated values but the value is no longer passed in the POST call when submitted in the form.
The hidden field
In firebug I see the value being updated properly when I select one or multiple options but for some reason the value gets lost in the submission process. I don't see much of a different where that could happen.
Use map()
$('#TopicID').change(function(){
var selectedText = $(this).find(':selected').map(function(){
return $(this).text(); //$(this).val()
}).get().join('|');
console.log(selectedText);
});
$('#TopicID').change(function(){
var selectedText = $(this).find(':selected').map(function(){
return $(this).text(); //$(this).val()
}).get().join('|');
console.log(selectedText);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="TopicID" multiple="true">
<option id="1">ABC</option>
<option id="2">XYZ</option>
<option id="3">PQR</option>
</select>
I have a situation here,
Using JQuery I'm appending some values in drop down list.. Even it is one or two value that appended in drop down list..
For Add,
tableui+='<option value="">'+resourceadd+'</option>';
$('#resourcess').append(tableui);
When the page reloads automatically the value stored in db.
For example 4 values added in dropdown list (Values are not stored in db), I want to delete last value. I'm using,
$("#resourcess :last-child").remove();
The same condition, I want to delete middle of two values, How to do it??
Assuming you know the value of the option you want to remove, you could use filter:
$('#resources option').filter(function() {
return this.value == 'foo'; // insert your value here.
}).remove();
Or an attribute selector:
$('#resources option[value="foo"]').remove();
If you don't know the value, but do know the position of the option within the select, you could remove it by index using eq():
$('#resources option').eq(1).remove(); // remove the 2nd option
I am filling a drop down based on the value selected in the first drop down.Data being sent back from server is in JSON format and using JQuery to parse and fill the second select tag
<select name="abc" id="jobName">
<option value="-1">Please select a Job</option>
</select>
This is my Jquery code
var selectedGroup = document.getElementById(groupDropDownId);
var groupdata = selectedGroup.options[selectedGroup.selectedIndex].value;
var formInput='group='+groupdata;
$.getJSON('search/getSchedulerJobListForGroup',formInput,function(data) {
$('.result').html('' + data.jobList + '');
$.each(data.jobList,function(index, value){
var jobId = document.getElementById(resetDropDownId);
var option=new Option(value,value);
try{
jobId.add(option);
}
catch(e){
jobId.appendChild(option);
}
});
});
$("#jobName")[0].selectedIndex = 1;
// $("#jobName").val($("#triggerjobName option:first").val());
in above code groupDropDownId is ID of the drop down based on whose value, second drop down will be filled.resetDropDownId is ID of second drop down which i am trying to fill from JSON data getting from the server.
Upon filling the drop down, its also creating an empty option tag and it is getting select by default.
I am not sure if i can add some default value to that empty option so that i can select that default option value like "please select bla bla."
also i tried to select first element from the drop down but nothing seems working for me.I am wondering what i am doing wrong here?
Based on your question, it looks like you want to know how to change the value and text of an element within a dynamically populated select list.
Currently, you have this statement $("#jobName")[0].selectedIndex = 1; sitting outside of your getJSON request. If you move this inside of the getJSON function, it will work as expected.
If you want to set the value and text of that object, you'll want to use ->
$('#jobId option:first').val("Some Value").text("other stuff");
You can see a working JS Fiddle using dynamically populated select list from a JSON object.

I'm trying to build some kind of currency converter and I have two select menus with the list of currencies.
I want to create a button that when clicked, it will switch the selection between the "from" select menu and the "to" select menu.
how do I implement it using the select menus I already have?
I believe you'r looking for a swap behavior.
http://jsfiddle.net/brentmn/D55Dm/
$(function(){
var $sel1 = $('#currency1');
var $sel2 = $('#currency2');
$('input[type=button]').click(function(){
var val1 = $sel1.val();
var val2 = $sel2.val();
$sel2.val(val1);
$sel1.val(val2);
//jqueryui
//$sel2.val(val1).trigger('change');
//$sel1.val(val2).trigger('change');
});
});
Something like this?
$("#button").on("click", function() {
var from = $("#from").val();
var to = $("#to").val();
$("#from").val(to);
$("#to").val(from);
});
I'd really do it with less code than that, but have done it like that for readability.
Assuming I've understood you correctly, you want a button that will swap the values of two select elements. If that's right, try something along these lines:
$("#someButton").click(function() {
var elemTo = $("#to"),
elemFrom = $("#from"),
toVal = elemTo.val();
elemTo.val(elemFrom.val());
elemFrom.val(toVal);
});
It simply gets references to the two select elements (assumed here to be #to and #from), gets the value of one of them, replaces the value of that one with the value of the other, and then replaces the value of the second with the stored value from the first.
Note that this assumes both select elements have the same option values. If an option is present in one select but not the other, it would not work.
Here's a working example.
If you dbl click on one item in 'From' section , it will get selected be appended to the 'To' section.
$("#selectFrom").dblclick(function(){
$selectTo.append($selectFrom.children(":selected"));
});
Which all functionalities you want??
I am trying to collect tick box values and assign the ticked boxes values to a hidden field so that I can save all of the ticked boxes values into one column in a comma delimited format, instead of many.
How could I go about doing that?
Thanx in advance!
You can use the map and join function like this:
var vals = $(':checkbox:checked').map(function(){
return $(this).val();
}).get().join(',');
// save the values to a hidden field
$('#hidden_id').val(vals);
