Don't show part of pull downs content? - javascript

I have some dropdowns in a form that are generated by a backoffice. At the end of each choice in the dropdown something is added between (brackets). How can I not show these brackets and their variable content? Leaving only the content before the brackets.
<select>
<option value="volvo">Volvo (30.000)</option>
<option value="saab">Saab (40.000)</option>
<option value="opel">Opel (15.000)</option>
<option value="audi">Audi (45.000)</option>
</select>
<select>
<option value="dog">Dog (300)</option>
<option value="cat">Cat (50)</option>
<option value="fish">Fish (5)</option>
</select>


Try this;
var carList=[{name:"Audi (45.000)" },{name:"Saab (40.000)"},{name:"Opel (15.000)"},{name:"Audi (45.000)"}];
var $cars=$("#cars");
$cars.empty();
carList.forEach(function(index){
$cars.append(new Option(index.name.split("(")[0].trim()))
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="cars">
</select>
For all select elements
$("select").each(function(){
var $wrapper=$(this);
var $options=$wrapper.find("option");
$wrapper.empty();
$options.each(function(index){
$wrapper.append(new Option($(this).text().split("(")[0].trim()))
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<select>
<option>Fiat (32.00)</option>
<option>Audi (12.00)</option>
</select>
<select>
<option>Bmw (32.00)</option>
<option>Tofas (22.00)</option>
</select>
<select>
<option>Dog (1.00)</option>
<option>Fish (0.00)</option>

Remove last option value from multiple select element using jQuery

I have two select element and I need to remove last option from both select using jQuery.
First Select Element
<select class="selBooks" name="select1" >
<option value="8247(random)">Opt2</option>
<option value="1939(random)">Opt1</option>
</select>
Second Select Element
<select class="selBooks" name="select2" >
<option value="8244(random)">Opt3</option>
<option value="1938(random)">Opt4</option>
</select>
jQuery
$(".selBooks option:last").remove();
When I try this it only removes last option of second select element. Please guide me if I am doing anything wrong or there is other way to achieve this.

iterate .selBooks with loop and remove the last element of that class.
$('.selBooks').each(function() {
$(this).find("option:last").remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="selBooks" name="select1" >
<option value="8247(random)">Opt2</option>
<option value="1939(random)">Opt1</option>
</select>
Second Select Element
<select class="selBooks" name="select2" >
<option value="8244(random)">Opt3</option>
<option value="1938(random)">Opt4</option>
</select>
jQuery

Try by name
$(".selBooks[name=select1] option:last").remove();
$(".selBooks[name=select2] option:last").remove();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="selBooks" name="select1" >
<option value="8247(random)">Opt2</option>
<option value="1939(random)">Opt1</option>
</select>
Second Select Element
<select class="selBooks" name="select2" >
<option value="8244(random)">Opt3</option>
<option value="1938(random)">Opt4</option>
</select>

Use last-child.
$('.selBooks option:last-child').remove();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="selBooks" name="select1">
<option value="8247(random)">Opt2</option>
<option value="1939(random)">Opt1</option>
</select>
<select class="selBooks" name="select2">
<option value="8244(random)">Opt3</option>
<option value="1938(random)">Opt4</option>
</select>

Show selected option with JS

I don't know how to make next:
I want that when someone selects items from combobox, that item be shown in div.
What do I need to do?
<body>
<h1>VEZBA STRUKTURA</h1>
<div id="prvi"></div>
<select name="automobili" id="automobili">
<option value="1">BMW</option>
<option value="2">AUDI</option>
<option value="3">OPEL</option>
<option value="4">FERARI</option>
<option value="5">SKODA</option>
<option value="6">HJUNDAI</option>
</select>
<script>
</script>
</body>

You need to attach an event listener that executes when the value of the select changes:
automobili.addEventListener('change', function() {
prvi.innerHTML = automobili.selectedOptions[0].textContent
})
<h1>VEZBA STRUKTURA</h1>
<div id="prvi"></div>
<select name="automobili" id="automobili">
<option value="1">BMW</option>
<option value="2">AUDI</option>
<option value="3">OPEL</option>
<option value="4">FERARI</option>
<option value="5">SKODA</option>
<option value="6">HJUNDAI</option>
</select>

On clicking on close button of page i want to clear all selectbox value

I have 3 selectbox on my page and onClick of close button I want to clear all the selectbox which are under the class .popup.
Below is my code to clear fields.
clearText: function() {
$('.popupBody input').val('');
$('.popupBody select').val('');
$('.popupForm').find('.errmsgActive').removeClass('errmsgActive');
$('.popupForm').find('.errmsg').html('');
}
For clearing all select boxes inside .popupBody class, I am using below code.
$('.popupBody select').val('');

For clearing selection made in select2 select box you can try following approach:
$('.popupBody select').each(function(){
//iterate over all the select boxes one by one
$(this).select2("val", ""); //clearing the selection made
});

try this, this will work for you.

<script type="text/javascript">
$(document).ready(function(){
$("#closebutton").click(function(){
$("div.popupBody select").val("");
});
});
</script>
</body>
</html>

To reset a dropdown you need to select the default element usually the first one:
$('.popupBody select').find('option:first-child').attr('selected','selected');
to reset the value in select2 use
$('.popupBody select').select2("val", "");

Your code is looks good.. obviously $('.popupBody select').val(''); is clearing value of select dropdown under .popupBody.
BUT
Make sure, all select input must have option value=''.
See below code
$(".popupBody select").select2();
$("#clear").click(function(){
$('.popupBody select').val('-1').change();
})

</select>
<select>

How to make option select selected by jquery

Here is my HTML.
<select class="height_selected" id="renderHeight">
<option>Select Height</option>
<option value="1">123 cm</option>
<option value="2">125 cm</option>
</select>
I want to make the Option 2 i.e., 125 cm as selected.
I tried
$('#1 :selected').text();
But it is not working.
How can i make the option 125 selected i.e., value that have #1 as selected
Update i have another option select
I want to make only the height to be selected.
<select class="weight_selected" id="renderWeight">
<option>Select Weight</option>
<option value="1">100 kg</option>
<option value="2">125 kg</option>
</select>

Use prop to select the option.
$('#renderHeight option[value="2"]').prop('selected', true);
Code Demo
$('option[value="2"]').prop('selected', true);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<select class="height_selected" id="renderHeight">
<option>Select Height</option>
<option value="1">123 cm</option>
<option value="2">125 cm</option>
</select>
You can also set the value using val().
$('#renderHeight').val(2);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<select class="height_selected" id="renderHeight">
<option>Select Height</option>
<option value="1">123 cm</option>
<option value="2">125 cm</option>
</select>

Try this : To make option selected, you can directly set value of select box to the value of option to be selected.
$(function(){
$('#renderWeight').val('2');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select class="weight_selected" id="renderWeight">
<option>Select Weight</option>
<option value="1">100 kg</option>
<option value="2">125 kg</option>
</select>

You can use val() by passing the option value
Live Demo
$('#renderHeight').val(2);

You can try this code
$('#renderHeight option').each(function(){
if($(this).text() =='123 cm'){
$(this).prop('selected',true)
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="height_selected" id="renderHeight">
<option>Select Height</option>
<option value="1">123 cm</option>
<option value="2">125 cm</option>
</select>

How to add content with select tag without refreshing the page(AJAX)

I am trying to make a page when someone clicks on a option in the select form, another select form appears then another without having to refresh the page. I know you use AJAX for not refreshing but my code is somehow not working when tried.
HTML
<div id="example">
<select id="foo">
<option value="">lets make another</option>
<option value="index.html">Demographic</option>
<option value="index.html">Crime</option>
<option value="index.html">School</option>
</select>
</div>
<div id="result">
</div>
javascript(AJAX)
$(document).ready(function() {
$('#example').on('click', 'button.switch', function() {
$.ajax('AjaxLoadedContent.html')
.done(function(response){
$('#result').html(response);
});
});
});
Content thats suppose to load(Another select form)
<select id="foo">
<option value="">Pick a site</option>
<option value="index.html">Demographic</option>
<option value="index.html">Crime</option>
<option value="index.html">School</option>
</select>
But whats wrong??

As #Goose said in the comments, instead of using an Ajax call you could hide the select boxes and show them based on the value of the shown select option, as shown below:
HTML
<div id="example">
<select id="foo">
<option value="">lets make another</option>
<option value="demographic">Demographic</option>
<option value="crime">Crime</option>
<option value="school">School</option>
</select>
<select id="demographic" class="toggle">
<option value="">Demographic</option>
<option value="d1">d1</option>
<option value="d2">d2</option>
<option value="d3">d3</option>
</select>
<select id="crime" class="toggle">
<option value="">Crime</option>
<option value="c1">c1</option>
<option value="c2">c2</option>
<option value="c3">c3</option>
</select>
<select id="school" class="toggle">
<option value="">School</option>
<option value="s1">s1</option>
<option value="s2">s2</option>
<option value="s3">s3</option>
</select>
</div>
<div id="result"></div>
CSS
.toggle {
display:none;
}
JS
$('#foo').on('change', function(){
var val = $(this).val();
$('.toggle').hide();
$('#'+val).show();
});
Fiddle

If your content is fairly static, I'd use the following code that doesn't invoke additional http calls:
HTML:
<div id="example">
<select id="foo">
<option value="">lets make another</option>
<option value="">Demographic</option>
<option value="">Crime</option>
<option value="">School</option>
</select>
</div>
<div id="result">
<select id="foo">
<option value="">Pick a site</option>
<option value="">Demographic</option>
<option value="">Crime</option>
<option value="">School</option>
</select>
</div>
JS:
$(function() {
$("#result").hide();
$("#foo").click(function() {
$("#result").show();
});
});
Let me know if it helps. Cheers!
