Im stack on creating multiple select options
I have an Object with multi objects inside and want create select options in condition of the previous select option , i provide js fiddle for better understanding .
my objectif is
first select category ----(then)---> select sex -----(then)---> select kind---(then)-->then select size
by this order from that Object.
i could do the select sex and it works but not kind and size.
this is my html
<form name="myform">
<div>
<select name="category_group" id="category_group" >
<option value="0">choose category</option>
<option value='401' > clothes </option>
<option value='403' > shoes </option>
</select>
</div>
<br>
<div>
<select id="clothing_sex" name="clothing_sex" onChange="showclothesKind(this.value,this.form.clothing_kind)">
<option value="0">choose Type»</option>
</select>
<select id="clothing_kind" name="clothing_kind">
<option value="0">choose clothes</option>
</select>
<select id="clothing_size" name="clothing_size">
<option value="0">choose size</option>
</select>
</div>
</form>
and js in the fiddle.
much appreciate your help.
This was kind of fun to play around with. Thanks for posting. I used the following:
var optionTemplate = "<option class='newOption'>sampleText</option>";
$(document).ready(function() {
var removeFromNextSelects = function(firstSelector) {
var selNum = sels.indexOf(firstSelector);
for (var i = selNum; i < sels.length; i++)
{
$(sels[i]).find('.option').remove();
}
};
var populateNextSelect = function(neededObject, targetSelector) {
removeFromNextSelects(targetSelector);
for (var key in neededObject)
{
var name;
neededObject[key].name ? name = neededObject[key].name : name = neededObject[key];
$(targetSelector).append(optionTemplate);
$('.newOption').val(key).html(name).removeClass('newOption').addClass('option');
}
};
var obj1 = {}, obj2 = {}, obj3 = {};
var sels = ["#clothing_sex", "#clothing_kind", "#clothing_size"];
$('#category_group').change(function() {
if ($(this).val() == 0)
{
removeFromNextSelects(sels[0]);
return;
}
obj1 = {};
var selection = $(this).val();
obj1 = clothes[selection];
populateNextSelect(obj1, sels[0]);
});
$('#clothing_sex').change(function() {
if ($(this).val() == 0)
{
removeFromNextSelects(sels[1]);
return;
}
obj2 = {};
var selection = $(this).val();
obj2 = obj1[selection].types;
populateNextSelect(obj2, sels[1]);
});
$('#clothing_kind').change(function() {
if ($(this).val() == 0)
{
removeFromNextSelects(sels[2]);
return;
}
obj3 = {};
var selection = $(this).val();
var arr = obj2[selection].sizes;
for (var i = 0; i < arr.length; i++)
{
obj3[Object.keys(arr[i])[0]] = arr[i][Object.keys(arr[i])[0]];
}
populateNextSelect(obj3, sels[2]);
});
});
Here's the fiddle

I have a dropdown with values. I have an array array with a list of values that will match the drop down values. If the value of text option of the dropdown exists in the array, it shouldn't show in the dropdown as an option. I am stuck on the approach I should use. This is what I have so far.
HTML
Car Plates:
<select title='car/id' id='car_x0020_Plate_x002f'>
<option selected="selected" value="0">none</option>
<option value="16">233-jj2</option>
<option value="10">934-zxy</option>
<option value="90">330-nbh</option>
<option value="11">930-orj</option>
</select>
JavaScript
var hideOption = ['233-jj2', '330-nbh']
var e = document.querySelector([id^='car']);
var strUser = e.value;
var e = document.getElementById("ddlViewBy");
var strUser = e.options[e.selectedIndex].text;
for (var x=0; x<hideOption.length; x++){
if (hideOption[x] === strUser){
//remove from dropdown
}
}
I made your idea in a very simple way, if you have any question please tell me
var hideOption = ['233-jj2', '330-nbh'],
select = document.getElementById("select");
for (let i = 0; i < hideOption.length; i = i + 1) {
for (let t = 1; t < select.options.length; t = t + 1) {
if (hideOption[i] == select.options[t].textContent) {
select.options[t].remove();
}
}
}
Car Plates:
<select title='car/id' id='select'>
<option selected="selected" value="0">none</option>
<option value="16">233-jj2</option>
<option value="10">934-zxy</option>
<option value="90">330-nbh</option>
<option value="11">930-orj</option>
</select>
// remove from dropdown
use this code to remove from dropdown
e.removeChild(e.options[e.selectedIndex])
you can use this also
e.selectedOptions[0].remove()
var hideOption = ['233-jj2', '330-nbh']
var e = document.querySelector("[id^='car']");
var selTextArr = Array.from(e.options).map(option => option.text)
for (var x=0; x<selTextArr.length; x++){
if (hideOption.includes(selTextArr[x])){
e.remove(x)
}
}
Car Plates:
<select title='car/id' id='car_x0020_Plate_x002f'>
<option selected="selected" value="0">none</option>
<option value="16">233-jj2</option>
<option value="10">934-zxy</option>
<option value="90">330-nbh</option>
<option value="11">930-orj</option>
</select>
var options = document.querySelector("[id^='car']").children;
var hideOption = ['233-jj2', '330-nbh']
for (var i = 0; i < options.length; i++){
if(hideOption.indexOf(options[i].text) > -1){
options[i].remove();
}
}
I've created dynamic dropdown list and I want to obtain values from selected option. Dynamic dropdown works fine but I have struggle with taking values from selected option.
For example I want to take value of avgDamage from selected object tpPrototype.
Need some help here

</select>
</div>
<div class="select">
<select name="opttwo" id="typeSel" size="1">
<option value="" selected="selected">Tank Type</option>
</select>
</div>
<div class="select">
<select name="optthree" id="nameSel" size="1">
<option value="" selected="selected">Tank Name</option>
</select>

for (let tank in tankObject) {
tankSel.options[tankSel.options.length] = new Option(tank, tank);
}
tankSel.onchange = function () {

tankSel.onchange();
typeSel.onchange = function () {
nameSel.length = 1;
if (this.selectedIndex < 1) return;
let names = tankObject[tankSel.value][this.value];

nameSel.options[nameSel.options.length] = new Option(names[i], names[i]);
}

This looks like a duplicate of question 1085801
Basically, once you have the selection object, you access the "value" attribute through:
var selectedValue = selectionObject.options[index].value;
or you can access the actual text, such as "Tank Type" in your initial HTML as:
var selectedText = selectionObject.options[index].text;
Once you have this, you should just be able to use that value/text to access your "tankObject" property:
var selectedAvgDamage = tpPrototype[selectedText];
I have 3 chained select boxes using jquery and json.
Depending on first 2 values I filter third one my code actually works but the problem is when I change values of first 2 select boxes third select recieves new datas while keeping old ones.
I've tried to empty my array but it didn't work.
$(document).ready(function() {
var json = JSON.parse(jsonString);
var makesArray = [];
var selectedyear;
var selectedcourse;
var $yearDropDown = $("#DropDown_Year");
var $course_type = $("#course_type");
$yearDropDown.change(function() {
selectedyear = this.value;
//filter based on selected year.
});
$course_type.change(function(){
selectedcourse = this.value;
makesArray = jQuery.grep(json, function(course, i) {
return course.course_type == selectedcourse && course.year_code == selectedyear;
})
var selectBox = document.getElementById('DropDown_Make');
for(var i = 0, l = makesArray.length; i < l; i++){
var option = makesArray[i];
selectBox.options.add( new Option(option.course_code, option.course_code, option.course_code) );
}
makesArray= []; //makesArray.empty();
});
});
<div id="DrpDwn">
Year:
<select id="DropDown_Year">
<option>Yıl</option>
<option value="15">2015-2016</option>
<option value="16">2016-2017</option>
</select>
<select class="form-control" id="course_type" name="course_type" required>
<option value="" selected> Choose</option>
<option value="Yos">YÖS</option>
<option value="SatMatGeo">SAT (MAT)</option>
<option value="SatCriRea">SAT (ENG)</option>
<option value="TomerABC">TÖMER (ABC)</option>

<option value="TomerB1B2">TÖMER (B)</option>
<option value="TomerC1C2">TÖMER (C)</option>
</select>
Make:
<select id="DropDown_Make">
<option>None</option>
</select>
</div>
and this is JSFIDDLE
https://jsfiddle.net/rw7cb8c5/25/
Make DropDown_Make empty using selectBox.innerHTML = "" in $course_type.change() like following.
$course_type.change(function () {
selectedcourse = this.value;
makesArray = jQuery.grep(json, function (course, i) {
return course.course_type == selectedcourse && course.year_code == selectedyear;
})
var selectBox = document.getElementById('DropDown_Make');
selectBox.innerHTML = ""; //added this line
for (var i = 0, l = makesArray.length; i < l; i++) {
var option = makesArray[i];
selectBox.options.add(new Option(option.course_code, option.course_code, option.course_code));
}
makesArray.empty();
});
UPDATED FIDDLE
I'm new to jquery, I'm working on a survey form and I have multiple dropdown menus for different questions but they all have the same dropdown value. Supposed I have:
<select name="Forms[AgentIsPitch]" id="Forms_AgentIsPitch">
<option value="">Choose One</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
<select name="Forms[MandatoryOptIsStated]" id="Forms_MandatoryOptIsStated">
<option value="">Choose One</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
And other different dropdowns with different id's. What is the best way to count how many has selected Yes, No and N/A/ ? Thanks
you can do it simple this way
$('select').change(function() {
// get all selects
var allSelects = $('select');
// set values count by type
var yes = 0;
var no = 0;
// for each select increase count
$.each(allSelects, function(i, s) {
// increase count
if($(s).val() == 'Yes') { yes++; }
if($(s).val() == 'No') { no++; }
});
// update count values summary
$('.cnt-yes').text(yes);
$('.cnt-no').text(no);
});
DEMO
Try this — https://jsfiddle.net/sergdenisov/h8sLxw6y/2/:
var count = {};
count.empty = $('select option:selected[value=""]').length;
count.yes = $('select option:selected[value="Yes"]').length;
count.no = $('select option:selected[value="No"]').length;
count.nA = $('select option:selected[value="N/A"]').length;
console.log(count);
My way to do it would be :
var optionsYes = $("option[value$='Yes']:selected");
var optionsNo = $("option[value$='No']:selected");
var optionsNA = $("option[value$='N/A']:selected");
console.log('number of yes selected = ' + optionsYes .length);
console.log('number of no selected = ' + optionsNo .length);
console.log('number of N/A selected = ' + optionsNA .length);
Check the console (or replace with alert).
With your code, it would be something like that (assuming you want to check on a button click event) :
<select name="Forms[AgentIsPitch]" id="Forms_AgentIsPitch">
<option value="">Choose One</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
<select name="Forms[MandatoryOptIsStated]" id="Forms_MandatoryOptIsStated">
<option value="">Choose One</option>
<option value="Yes">Yes</option>
<option value="No">No</option>
<option value="N/A">N/A</option>
</select>
<button class="btn btn-primary" id="countYes"></button>
<script type="text/javascript">
$('#countYes').on('click', function(){
var optionsYes = $("option[value$='Yes']:selected");
var optionsNo = $("option[value$='No']:selected");
var optionsNA = $("option[value$='N/A']:selected");
console.log('number of yes selected = ' + optionsYes .length);
console.log('number of no selected = ' + optionsNo .length);
console.log('number of N/A selected = ' + optionsNA .length);
});
</script>
You can check at another event, I choosed a button click just for example.
There is likely a cleaner way to do this, but this will get the job done (assuming there is a button click to trigger things):
$("#theButton").on('click', function() {
var totalSelect = 0;
var totalYes = 0;
var totalNo = 0;
var totalNA = 0;
$("select").each(function(){
totalSelect++;
if ($(this).val() == "Yes") { totalYes++; }
if ($(this).val() == "No") { totalNo++; }
if ($(this).val() == "N/A") { totalNA++; }
});
});
Hope this helps the cause.
In common you can use change event:
var results = {};
$('select').on('change', function() {
var val = $(this).val();
results[val] = (results[val] || 0) + 1;
});
DEMO
If you want count for each type of select:
$('select').on('change', function() {
var val = $(this).val();
var name = $(this).attr('name');
if (!results[name]) {
results[name] = {};
}
results[name][val] = (results[name][val] || 0) + 1;
});
DEMO
In the results will be something like this:
{
"Forms[AgentIsPitch]": {
"Yes": 1,
"No": 2,
"N/A": 3
},
"Forms[MandatoryOptIsStated]": {
"No": 5,
"N/A": 13
},
}
UPD: for counting current choice:
$('select').on('change', function() {
var results = {};
$('select').each(function() {
var val = $(this).val();
if (val) {
results[val] = (results[val] || 0) + 1;
}
})
console.log(results);
});
DEMO
So, I have an object named products that has 3 attributes:
var products = [
{"name":"product1","size":"large","color":"blue","gender":"male"},
{"name":"product2","size":"small","color":"pink","gender":"female"},
{"name":"product3","size":"large","color":"green","gender":"male"},
{"name":"product4","size":"large","color":"yellow","gender":"female"},
{"name":"product5","size":"medium","color":"blue","gender":"female"},
{"name":"product6","size":"large","color":"green","gender":"male"},
{"name":"product7","size":"small","color":"yellow","gender":"male"},
{"name":"product8","size":"medium","color":"red","gender":"female"},
{"name":"product9","size":"large","color":"blue","gender":"male"},
{"name":"product10","size":"small","color":"red","gender":"female"}
];
So, if I have 3 select boxes for size, color, and gender, how would I filter these 3 to get the product name?
I'm trying to use .filter in javascript. I know how to use it in non-associative arrays. But, what about associative arrays? how do you use them?
var color = document.getElementById("color").value;
var gender = document.getElementById("gender").value;
var size = document.getElementById("size").value;
var matched = products.filter(function(e) {
return (e.color == color && e.gender == gender && e.size == size);
}).map(function(e) { return e.name; });
I wrote a JSfiddle to go with this answer. Check it out here: http://jsfiddle.net/THEtheChad/XjGPt/
JQuery
$('input').change(function(){
var names = filter();
});
function filter(){
var selected = {
size: $('#size') .val(),
color: $('#color') .val(),
gender: $('#gender').val()
};
var matches = products.filter(function(product){
return product.size == selected.size &&
product.color == selected.color &&
product.gender == selected.gender;
});
return matches.map(function(product){ return product.name });
}
Vanilla JS
var d = document;
var inputs = d.getElementsByTagName('input');
// Convert to array
inputs = Array.prototype.slice.call(inputs);
inputs.forEach(function(input){
input.addEventListener('change', function(e){
var names = filter();
});
});
function filter(){
var selected = {
size: d.getElementById('size') .value,
color: d.getElementById('color') .value,
gender: d.getElementById('gender').value
};
var matches = products.filter(function(product){
return product.size == selected.size &&
product.color == selected.color &&
product.gender == selected.gender;
});
return matches.map(function(product){ return product.name });
}
Not as elegant as Barmar's code, I implemented 2 out of the 3 dropboxes and left a bit of work for you as well ;)
