I need to change the 3rd field automatically depending on first two field. ( it would be best if I change 3rd field and then first 2 fields changes also )
I need a Jquery solution. Anyone can help me please?
<select id="First">
<option val="car">car</option>
<option val="phone">phone</option>
</select>
<select id="Second">
<option val="car">car</option>
<option val="phone">phone</option>
<option val="boll">boll</option>
</select>
<hr>
<select id="ChangeItAutomatically">
<option val="carcar">car car</option>
<option val="carphone">car phone</option>
<option val="carboll">car boll</option>
<option val="phonecar">phone car</option>
<option val="phonephone">phone phone</option>
<option val="phonecarboll">phone boll</option>
</select>
Is this what you're looking for?
$(document).ready(function() {
// on change for the 3rd select
$("#ChangeItAutomatically").on("change", function() {
// get the value and split on space
var value = $(this).val().split(" ");
// select the other two selects based on the values
$("#First").val(value[0]);
$("#Second").val(value[1]);
});
// on change for the first two selects
$("#First, #Second").on("change", function() {
// set the value of the 3rd select based on the combination of values of the first two
$("#ChangeItAutomatically").val($("#First").val() + " " + $("#Second").val());
});
});

I have 3 dropdowns in a form:
<select id="1" required>
<option value="">Select type</option>
<option value="1">Car</option>
<option value="2">Truck</option>
<option value="3">Some other option</option>
</select>
<select id="2" required>
<option value="">Select option</option>
<option value="1">Small Car</option>
<option value="2">Big Car</option>
</select>
<select id="3" required>
<option value="">Select option</option>
<option value="1">Small Truck</option>
<option value="2">Big Car</option>
</select>
I need the second and third dropdown to appear/disappear based on selection of the first dropdown. 2 and 3 have to be hidden on page load, or when value 3 is selected on dropdown 1, but not just hidden from view, rather completely non-existant. I say this because jquery .show and .hide only makes an element disappear from display, it still stays inside the code and because of the "required" attribute inside those hidden dropdowns, form cannot submit.
I have tried this as well as many other answers I found, but had no luck...
<script>
$("#1").change(function () {
if ($(this).val() == '1') {
$('#2').show();
$('#3').hide();
} else if ($(this).val() == '2') {
$('#3').show();
$('#2').hide();
} else {
$("#2").hide();
$('#3').hide();
}
})
</script>
Please help...
Edit:
Something along those lines:
<form id="form">
<select id="1" required>
<option value="">Select type</option>
<option value="1">Car</option>
<option value="2">Truck</option>
<option value="3">Some other option</option>
</select>
<div id="here">
<select id="2" required>
<option value="">Select option</option>
<option value="1">Small Car</option>
<option value="2">Big Car</option>
</select>
<select id="3" required>
<option value="">Select option</option>
<option value="1">Small Truck</option>
<option value="2">Big Car</option>
</select>
</div>
</form>
$("#1").change(function () {
if ($(this).val() == '1') {
$('#2').appendTo( "#here" );
$('#3').remove();
} else if ($(this).val() == '2') {
$('#3').appendTo( "#here" );
$('#2').remove();
} else {
$('#2').remove();
$('#3').remove();
}
})
I am not very good at jquery. This does what I want, but only once. I dont know how to bring them back once removed. For example, if I selected from #1: 1(Car) and from #2: 1(Small Car), #3 will be removed. But if i now decide to choose another option on #1 nothing happens. Also, on load, all 3 are shown, I wanted to keep #2 and #3 hidden until an option on #1 is selected.
Here's one way to go about it. Instead of using numbers as ID's, why not use a data-attribute. Each time a select option is chosen the code will show the next one in the sequence.
$(document).ready(() => {
$('select[data-order=1]').show()
let selects = $('select[data-order]');
selects.change(function() {
// get number
let num = +$(this).data('order');
// show the next select and hide all selects after that
selects.each(function(i,o) {
let thisNum = +$(o).data('order');
if (thisNum === num + 1) $(o).show().val(''); // show and reset the value
else if (thisNum > num + 1) $(o).hide();
})
})
})
select[data-order] {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="form">
<select data-order='1' id="1" required>
<option value="">Select type</option>
<option value="1">Car</option>
<option value="2">Truck</option>
<option value="3">Some other option</option>
</select>
<select data-order='2' id="2">
<option value="">Select option</option>
<option value="1">Small Car</option>
<option value="2">Big Car</option>
</select>
<select data-order='3' id="3">
<option value="">Select option</option>
<option value="1">Small Truck</option>
<option value="2">Big Car</option>
</select>
</form>
I want to change multiple select buttons's values with another select button.
Practically when someone select an option in the main select button, the other select buttons must change with that value.
EDIT: I added the code, the first is the main select button and after I select somethig there, it should change in the others.
<select class="select_format">
<option value="0.49">9x13</option>
<option value="0.59">10X15</option>
<option value="0.99">13X18</option>
<option value="1.20">15X21</option>
<option value="2.60">20X30</option>
</select>
<select name="format[]" class="format_imgs">
<option value="0.49">9x13</option>
<option value="0.59">10X15</option>
<option value="0.99">13X18</option>
<option value="1.20">15X21</option>
<option value="2.60">20X30</option>
</select>
<select name="format[]" class="format_imgs">
<option value="0.49">9x13</option>
<option value="0.59">10X15</option>
<option value="0.99">13X18</option>
<option value="1.20">15X21</option>
<option value="2.60">20X30</option>
</select>
<select name="format[]" class="format_imgs">
<option value="0.49">9x13</option>
<option value="0.59">10X15</option>
<option value="0.99">13X18</option>
<option value="1.20">15X21</option>
<option value="2.60">20X30</option>
</select>
Thanks.
Since you didn't supply code here's a guess:
$(".myTriggerButton").on("click", function() {
$(".buttonToChangeValue").each(function() {
this.value = "new value";
});
});
$('.select_format').change(function(){
$('.format_imgs').val( $(this).val() );
});

I have a select like this
<select name="category" >
<option value="0" selected>Select a Manufacturer</option>
<option value="10">Acer Technologies</option>
<option value="2">Alcatel</option>
<option value="14">Apple Iphone</option>
<option value="4">Azumi</option>
<option value="12">HTC Corporation</option>
<option value="8">Huawei</option>
<option value="5">LG Electronics</option>
<option value="11">Motorola</option>
<option value="9">Nokia Microsoft</option>
<option value="1">Samsung</option>
<option value="6">Sony Ericsson</option>
<option value="3">Zhong Xing ZTE</option>
</select>
And another select HIDDEN like this
<select name="manufacturer" >
<option value="none" selected>Select a Manufacturer</option>
<option value="Acer Technologies">Acer Technologies</option>
<option value="Alcatel">Alcatel</option>
<option value="Apple Iphone">Apple Iphone</option>
<option value="Azumi">Azumi</option>
<option value="HTC Corporation">HTC Corporation</option>
<option value="Huawei">Huawei</option>
<option value="LG Electronics">LG Electronics</option>
<option value="Motorola">Motorola</option>
<option value="Nokia Microsoft">Nokia Microsoft</option>
<option value="Samsung">Samsung</option>
<option value="Sony Ericsson">Sony Ericsson</option>
<option value="Zhong Xing ZTE">Zhong Xing ZTE</option>
</select>
Both selects are almost the same value, the first one is to save the manufacturer as category and the second one is to save the manufacturers name
The first one is visible while the second one is hidden ( display:none )
What I need is:
If the user select in select one for example
<option value="2">Alcatel</option>
In some way the hidden display:none select must be autoselected to
<option value="Alcatel">Alcatel</option>
Any way to do this?
I already have Jquery running other functions on the site
Thanks
Use change function:
$( "select[name='category']" ).change(function(e) {
$( "select[name='manufacturer']" ).val( $(this).find( "option:selected" ).text() );
});
But if option text in category select do not match option value in manufacturer select - code will not work.
I have some code that has one contact select box hard coded and then if you click on a add button it adds more contacts. Each contact can be selected from a dropdown and give a location in at location text box.
I want on submit to be able to know if they have selected someone and if not I want to clear out the Location box as there cannot be a location if there is no contact.
<!--- The myContactCount variable is set in another part of javascript this is the current count plus one of the number of current select boxes. --->
<script type="text/javascript" language="javascript">
var e='';
var contactSelectedValue='';
for(var i=1;1<myContactCount;i++){
e = document.getElementById('myContactID_'+i);
contactSelectedValue = e.options[e.selectedIndex].value;
/* I am trying to alert the value so I can then use a if statement to check for null or even change the 'Select a Contact' value to 0 and test for that. */
alert(contactSelectedValue);
}
</script>
<!--- the ID will be 1-100 depending on how many contacts they have added --->
<select name="myContactID_#ID#">
<option value="">Select a Contact</option>
<option value="1">Abe</option>
<option value="2">Barbara</option>
<option value="3">Cavlin</option>
</select>
So after they are created dynamically they code would look like this.
<select name="myContactID_1">
<option value="">Select a Contact</option>
<option value="1">Abe</option>
<option value="2">Barbara</option>
<option value="3" selected="selected">Cavlin</option>
</select>
<select name="myContactID_2">
<option value="">Select a Contact</option>
<option value="1">Abe</option>
<option value="2" selected="selected">Barbara</option>
<option value="3">Cavlin</option>
</select>
<select name="myContactID_3">
<option value="">Select a Contact</option>
<option value="1" selected="selected">Abe</option>
<option value="2">Barbara</option>
<option value="3">Cavlin</option>
</select>
Your script has couple of issues:-
1<myContactCount instead of i<=myContactCount and you are using name in the select and
trying to fetch it by id.
Demo
Html
<select id="myContactID_1">
<option value="">Select a Contact</option>
<option value="1">Abe</option>
<option value="2">Barbara</option>
<option value="3" selected="selected">Cavlin</option>
</select>
<select id="myContactID_2">
<option value="">Select a Contact</option>
<option value="1">Abe</option>
<option value="2" selected="selected">Barbara</option>
<option value="3">Cavlin</option>
</select>
<select id="myContactID_3">
<option value="">Select a Contact</option>
<option value="1" selected="selected">Abe</option>
<option value="2">Barbara</option>
<option value="3">Cavlin</option>
</select>
JS
var e='';
var contactSelectedValue='';
for(var i=1;i<=3;i++){
e = document.getElementById('myContactID_'+i);
contactSelectedValue = e.options[e.selectedIndex].value;
/* I am trying to alert the value so I can then use a if statement to check for null or even change the 'Select a Contact' value to 0 and test for that. */
alert(contactSelectedValue);
}
I am not really a web person and am having trouble creating a cascading combo box. I have my options, but when I cannot figure out how to do a JavaScript command to switch the second box depending on the first box's selection.
These are my first set of options:
<select id="searchType" onchange="selectedOption(this)">
<option value="sessions">Sessions</option>
<option value="files">Files</option>
<option value="clients">Clients</option>
</select>
Depending on what they click there I would like to show these set of options:
SESSIONS
<select id="secondOptions">
<option value="conf">Config ID</option>
<option value="length">Length</option>
<option value="date">Date</option>
</select>
FILES
<select id="secondOptions">
<option value="id">File ID</option>
<option value="length">Length</option>
<option value="sent">Sent</option>
<option value="sessionId">Session ID</option>
</select>
CLIENTS
<select id="secondOptions">
<option value="name">Client Name</option>
<option value="organization">Organization</option>
<option value="specialty">Specialty</option>
<option value="sessionId">Session ID</option>
</select>
And finally a textbox to type into to really specify the search.
Once again, I am trying to do this using JavaScript, but if there is a better way to do this let me know please.
Given the amended html mark-up:
<form action="#" method="post">
<select id="searchType">
<option value="sessions">Sessions</option>
<option value="files">Files</option>
<option value="clients">Clients</option>
</select>
<select id="sessions">
<option value="conf">Config ID</option>
<option value="length">Length</option>
<option value="date">Date</option>
</select>
<select id="files">
<option value="id">File ID</option>
<option value="length">Length</option>
<option value="sent">Sent</option>
<option value="sessionId">Session ID</option>
</select>
<select id="clients">
<option value="name">Client Name</option>
<option value="organization">Organization</option>
<option value="specialty">Specialty</option>
<option value="sessionId">Session ID</option>
</select>
<fieldset id="textAreaSearchBox">
<legend>Search:</legend>
<textarea></textarea>
</fieldset>
</form>
(Note the changed ids, wrapping the form elements in a form, the addition of a fieldset, legend and textarea in the mark-up), the following JavaScript seems to work:
var select1 = document.getElementById('searchType');
var selects = document.getElementsByTagName('select');
select1.onchange = function() {
var select2 = this.value.toLowerCase();
for (i = 0; i < selects.length; i++) {
if (selects[i].id != this.id) {
selects[i].style.display = 'none';
}
}
document.getElementById(select2).style.display = 'block';
document.getElementById('textAreaSearchBox').style.display = 'block';
};
