I am currently trying to make a simple web application which logs to the console the values that are selected in an HTML drop-down menu. However, whenever I change my options in a different select, it ends up showing a value in the #player select. For example, if I chose Shot on Cage and clicked save, the console would show that the value to be b. If I am not explaining this thoroughly enough, please let me know, and I will try to re-explain my difficulties.
function myFunction() {
var a = document.getElementById("player").selectedIndex;
console.log(document.getElementsByTagName("option")[a].value);
var b = document.getElementById("what").selectedIndex;
console.log(document.getElementsByTagName("option")[b].value);
var c = document.getElementById("where").selectedIndex;
console.log(document.getElementsByTagName("option")[c].value);
var d = document.getElementById("when").selectedIndex;
console.log(document.getElementsByTagName("option")[d].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>
<option value="j">J</option>
<option value="ja">Ja</option>
</select>
<select id="what">

This will work for you.
.getElementsByTagName("option") will ruin your result as it will select all the <option> tags and it post the result as one.
So try this code it will work.
function myFunction() {
var a = document.getElementById("player");
console.log(a.options[a.selectedIndex].value);
var b = document.getElementById("what");
console.log(b.options[b.selectedIndex].value);
var c = document.getElementById("where");
console.log(c.options[c.selectedIndex].value);
var d = document.getElementById("when");
console.log(d.options[d.selectedIndex].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>
<option value="j">J</option>
<option value="ja">Ja</option>
</select>
<select id="what">
<option value="shoton">Shot on Cage</option>
<option value="shotoff">Shot off Cage</option>
<option value="goal">Goal</option>
<option value="assist">Assist</option>
<option value="block">Block</option>
<option value="steal">Steal</option>

<select id="where">

<option value="navy">Navy</option>
<option value="leftwing">1/2 side past 5</option>
<option value="rightwing">4/5 side past 5</option>
<option value="point">Point/3</option>
<option value="lefttwo">1/2 side 2 meter</option>
<option value="righttwo">4/5 side 2 meter</option>
<option value="1">6 on 5 1</option>
<option value="2">6 on 5 2</option>
<option value="3">6 on 5 3</option>
<option value="4">6 on 5 4</option>
<option value="5">6 on 5 5</option>
<option value="6">6 on 5 6</option>
</select>
<select id="when">
<option value="q1">Quarter 1</option>
<option value="q2">Quarter 2</option>
<option value="q3">Quarter 3</option>
<option value="q4">Quarter 4</option>
</select>
<button type="button" onclick="myFunction()"> Save </button>
options[a.selectedIndex].value this simple will get you the value of the selected option value in the select and in javascript option in a property of select which we can combain with selectedIndex property and get you value.
Hope this was helpfull.
you have many options split into 4 selects ... document.getElementsByTagName will receive them ALL ... so using the selectedIndex is only valid for the fist select
you can use getElementsByTagName on any element - so, in this case you would use it on the select element
function myFunction() {
var a = document.getElementById("player");
console.log(a.getElementsByTagName("option")[a.selectedIndex].value);
var b = document.getElementById("what");
console.log(b.getElementsByTagName("option")[b.selectedIndex].value);
var c = document.getElementById("where");
console.log(c.getElementsByTagName("option")[c.selectedIndex].value);
var d = document.getElementById("when");
console.log(d.getElementsByTagName("option")[d.selectedIndex].value);
}
<select id="player">
<option value="b">B</option>
<option value="n">N</option>
<option value="a">A</option>
<option value="c">C</option>
<option value="m">M</option>

<option value="point">Point/3</option>
<option value="lefttwo">1/2 side 2 meter</option>
<option value="righttwo">4/5 side 2 meter</option>
<option value="1">6 on 5 1</option>
<option value="2">6 on 5 2</option>
<option value="3">6 on 5 3</option>
<option value="4">6 on 5 4</option>
<option value="5">6 on 5 5</option>
<option value="6">6 on 5 6</option>

<select id="when">

<option value="q3">Quarter 3</option>
<option value="q4">Quarter 4</option>
</select>
<button type="button" onclick="myFunction()"> Save </button>
That being said, this still isn't the best solution - use #weBBer's code INSTEAD
because a <select> element has a property called options, which you can use the selectedIndex property to get the selected <option> - see the better answer for an example

I have two Selectbox groups.
When the user selects an item from the 1st Selectbox group; According to the selected Value, I want to disable some of the items in the 2nd Selectbox group.
Below is my sample code. The example scenario I want to do based on the following set of code is as follows:
<select name="group1" id="group1">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
<select name="group2" id="group2">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
For example: If the user selects <option value="22">Opt 4</option> from the 1st Selectbox,
In Selectbox 2. group this option items should automatically become "disabled" in the group:
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
So what I want to do is as follows: According to the value values in the Selectbox, after each item selection, it should be able to select larger values of the current selection in the other Selectbox step.
Using the jQuery on('change' listener, we can access the current selected value with $(this).val() - then loop through the second select, setting .prop('disabled' to true/false based on it's value being equal to or less than the first selected value. Because we're comparing Numbers but the values we're getting are strings, we need to convert them with Number(), parseInt() or the shorthand prefix operator +
$('#group1').on('change', function() {
let val = Number($(this).val());
$('#group2 option').each(function() {
$(this).prop('disabled', Number($(this).val()) <= val)
})
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="group1" id="group1">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
<select name="group2" id="group2">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
$('#group1').on('change' , function(){
var value = $(this).find('option:selected').val();
$('#group2').find('option').prop('disabled',false);
$('#group2').find('option').each(function(i,e){
var opt = $(e);
if(opt.val() < value){
opt.prop('disabled',true);
}
})
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="group1" id="group1">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
<hr>
<select name="group2" id="group2">
<option value="12">Opt 1</option>
<option value="13">Opt 2</option>
<option value="21">Opt 3</option>
<option value="22">Opt 4</option>
<option value="24">Opt 5</option>
<option value="35">Opt 6</option>
<option value="57">Opt 7</option>
<option value="62">Opt 8</option>
</select>
I am sharing an example above. When there is a change in the first selectbox, it takes the selected value and compares the second selectbox, if the selected value is large, it adds a disabled attribute.
After selecting option from list hide placeholder (Select option). If after clicked on select box placeholder must be hidden.
<select class="name">
<option value="">Select Option</option>
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
</select>
You could do it like this:
$("select").change(function() {
$(this).find("option:first").hide();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select class="name">
<option value="">Select Option</option>
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
</select>
you can set a js-handler, to remove the Option-noe (here the jQuery Version):
<select class="name" id="myselect">
<option value="">Select Option</option>
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
</select>
and the js
jQuery(function(){
jQuery ('#myselect').on('change', function(){
jQuery(this).find('[value=""]').remove();
})
});
https://jsfiddle.net/k08zj6r9/
if you wish, you can disable the node, instead of remove.
jQuery(this).find('[value=""]').attr('disabled','disabled');
This question has been asked on this forum multiple times. Yet every time I've applied the code and edited the fields to accommodate my code it doesn't seem to work. Essentially I'm trying to develop a list from a form, so once the fields are filled out and you click the add button. The info provided would populate in an ordered list below the form. Here is the following html and javascript code I've got so far. When I click the add button the information that was typed gets showed in the url bar after the original domain name, but it never makes a list.
var list = document.getElementById('list');
function add(){
var name = document.getElementById('name').value;
var people = document.getElementById('people').value;
var phone = document.getElementById('phone').value;
var entry = document.createElement('li');
entry.appendChild(document.createTextNode(name + people + phone));
list.appendChild(entry);
return false;
}

Well, your code works when run as a SO Snippet (see below), so we will need more info about the problem you're having before we can answer your question.
That said, I did notice that your new list item was adding twice, and this is because you are running the add() function twice: Once for the onclick handler on the button press, and once as the action of the form upon submit. So, we need to remove one of those... I bet that you'll end up wanting to keep the form, but my working code below removes the form (keeping the onclick on the button) because I bet that your problem is that, although your code works, you are refreshing your page with the form, clearing out the options that have been added to your list. If this sounds right to you then look into passing/fetching the new list items via GET params.
var list = document.getElementById('list');
function add(){
var name = document.getElementById('name').value;
var people = document.getElementById('people').value;
var phone = document.getElementById('phone').value;
var entry = document.createElement('li');
entry.appendChild(document.createTextNode(name + people + phone));
list.appendChild(entry);
return false;

This may help assuming each field has an id:
document.querySelector('#yourButton').addEventListener('click', function(e){
/* Stop the form from submiting if useful */
e.preventDefault();
/* get the values of fields one at a time */
var field1 = document.querySelector('#input1').value;
var field2 = document.querySelector('#input2').value;

So I want to return a user's form results in a div so they can see what they have chosen underneath the form using JQuery but struggling to use the right code? Ive tried using the .html function and replaceWith. etc but nothing seems to be working?
Here's my html code:
<form id="myform">
<h4>Enter your booking slot here:</h4><br>
<select id="programmes">
<option value="test1">Test 1</option>
<option value="test2">Test 2</option>
<option value="test3">Test 3</option>
<option value="test4">Test 4</option>
<option value="test5">Test 5</option>
</select><br><br>
<select id="time">
<option value="one">01:00</option>
<option value="two">02:00</option>
<option value="three">03:00</option>
<option value="four">04:00</option>
<option value="five">05:00</option>
<option value="six">06:00</option>
<option value="seven">07:00</option>
<option value="eight">08:00</option>
<option value="nine">09:00</option>
<option value="ten">10:00</option>
<option value="eleven">11:00</option>
<option value="twevle">12:00</option>
<option value="one-pm">13:00</option>
<option value="two-pm">14:00</option>
<option value="three-pm">15:00</option>
<option value="four-pm">16:00</option>
<option value="five-pm">17:00</option>
<option value="six-pm">18:00</option>
<option value="seven-pm">19:00</option>
<option value="eight-pm">20:00</option>
<option value="nine-pm">21:00</option>
<option value="ten-pm">22:00</option>
<option value="eleven-pm">23:00</option>
<option value="midnight">00:00</option>
</select><br><br>
<button type="submit" value="Submit Booking">
</form>
</div>
<div></div>
$('#select').on('change', function() {
$('#result').html( $(this).find('option:selected').text() )
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="select">
<option value="test_1">Test 1</option>
<option value="test_2">Test 2</option>
<option value="test_3">Test 3</option>
<option value="test_4">Test 4</option>
<option value="test_5">Test 5</option>
</select>
<div id="result"></div>
I have this code which resets all the dropdowns when dropdown1 changes.
<select id="name" >
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
<select id="name2" class="whatever">
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
<select id="name3" class="whatever">
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
<select id="name4" class="whatever">
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
<select id="name5" class="whatever">
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
<select id="name6" class="whatever">
<option value="">select all</option>
<option value="1">Text 1</option>
<option value="2">Text 2</option>
<option value="3">Text 3</option>
</select>
I wanted to select the class and reset all of them at once but the only way to do it is with: $('select').val('').selectmenu('refresh');
But what if I want to specify a custom class name like in this case "whatever". How can I do it?
This is my jsfiddle
Working fiddle.
You have just to add it after select :
$('#name').change(function(){
$('select.whatever').val('').selectmenu('refresh');
});
Hope this helps.
