Currently I am using jQuery to hide/show select options using following code.
$("#custcol7 option[value=" + sizeValue + "]").hide();
This works fine in Firefox, but doesnt do any good in other browsers. How to I hide options from select in Chrome, Opera and IE?
I just came across this and instead of cloning the entire select over and over I just replaced the options that need to be hidden with span elements and hiding the spans ( though the browser didnt visually show them anyway, I think ) - you may need to change your code ( if complex ) to iterate through the spans for complex logic.
The spans store a reference to the option and replace themselves with it when they need to be shown.
This code can obviously be refactored and prettified.

EDIT #2 ( USE THIS INSTEAD ): It occurred to me that instead of doing all this clone/reference/replace crap, just wrap the option with a span, hide the span, and on show just replace the span with the option again..
http://fiddle.jshell.net/FAkEK/25/show/
I think meder has provided valid answer and here it is slightly changed to reflect what works for me:
$.fn.optVisible = function( show ) {
if( show ) {
this.filter( "span > option" ).unwrap();
} else {
this.filter( ":not(span > option)" ).wrap( "<span>" ).parent().hide();
}
return this;
}
Tested with (long live BrowserStack):
Windows XP: IE 6.0, Firefox 3.0, Safari 4.0, Opera 10.0, Chrome 14.0
Windows 8: IE 10.0 Metro
iOS 3.2 (iPad), iOS 6.0 (iPhone 5)
Android 1.6 (Sony Xperia X10)

You don't, it's not supported in IE (and assumably not in Chrome or Opera either). You would have to remove the options altogether and add them back later if you want them to be truly invisible. But in most cases a simple disabled="disabled" should suffice and is a heck of a lot simpler than handling the removing and adding of options.
try detach().
you can reattach it later if needed using append() or insertAfter()
To Remove options use:
var opt=$("option").detach();
To show options use:
opt.appendTo( "select" );
Just deleted it and store it in a var in your JavaScript. You can just create the new object when you need it later.
Otherwise try the disabled attribute mentioned above.
/**
* Change visibility of select list option elements
* #param {boolean} stateVal show hidden options if true; hide it otherwise. If not setted then toggle visibility, based on it's current state
*/
$.fn.toggleOptionVisibility = function (stateVal) {
var isBool = typeof stateVal === "boolean";
return this.each(function () {
var $this = $(this);
if (isBool) {
if (stateVal) $this.filter("span > option").unwrap();
else $this.filter(":not(span > option)").wrap("<span>").parent().hide();
}
else {
$this.filter("span > option").toggleOptionVisibility(true);
$this.filter(":not(span > option)").toggleOptionVisibility(false);
}
});
};
the way you did it should work in chrome but nvm.Here is another way
select = $('#custcol7');
select.find('option[value=["'+sizeValue +'"]').remove();
and if you want to show it again:
select.append('<option value="'+sizeValue+'"></option>');
It works perfectly on every browser and its really simple code. The problem is if you want to hide several options it is more typing .. but that can be solved by putting them into variables if they don't change dynamically like that :
var options = '<option value="'+sizeValue1+'"></option><option value="'+sizeValue2+'"></option><option value="'+sizeValue3+'"></option>';
select.append(options);
This way if you have to remove/append on several places you only typed the options once.Hope i gave another interesting option. Best Regards.
There's also the the .load method:
s_parent.change(function(){
s_child.load('./fetch_options.php",{'v',s_parent.val()});
}
The 'fetch_options.php' script would simply print the option tags based on whatever data source you use and the parent value(s) being passed in.
using the solution provided by AuthorProxy, it works fine for IE but when I attempt to do a .val() on the dropdown in firefox I get some funky values that don't make any sense. I have modified their option to include browser specific functionality, hide/show works for firefox.
$.fn.toggleOptionVisibility = function (stateVal) {
var isBool = typeof stateVal === "boolean";
return this.each(function () {
var $this = $(this);
if (navigator.userAgent.indexOf('MSIE') > -1 || navigator.userAgent.indexOf('Trident') > -1) {
if (isBool) {
if (stateVal) $this.filter("span > option").unwrap();
else $this.filter(":not(span > option)").wrap("<span>").parent().hide();
}
else {
$this.filter("span > option").toggleOptionVisibility(true);
$this.filter(":not(span > option)").toggleOptionVisibility(false);
}
}
else {
if (isBool) {
$this.show();
}
else {
$this.hide();
}
}
});
};
My take is bit different to other answers.
The aim is not to hide the options but just make them disable(to keep the UI consistent).
My Scenario :
I have multiple selects in a form and when an user selects an option in one of the selects the other selects should disable this option and vice versa. User is restricted from selecting the same option which is already selected. We normally disable the option but for IE 7 which does not support it. User also gets an option to add new selects.
Solution :
On load :
If the browser is IE7 then while populating the the selects and disabling the already selected options on other selects I am adding a custom attribute to the option("data-ie7-disabled") and also changing the color of the disabled options to '#cccccc'(which is the standard color for disabled options). This makes the UI look same across browsers.
On Change :
I save the previous option in a local variable(this is saved on focus).
When a user tries to change an option
User selects a complete new option which is not selected in any other dropdown. Then I loop through other selects and change the color and add custom attribute to this selected option on other selects.
When user selects an option that is already selected(The option which has grayed out color). I check if the option has this custom attribute on it first. If it has then > I simply revert the option to the previous one with an error message saying "This option is already selected or BLAH BLAH".
When user changes his existing option to a brand new option which is not selected in any other dropdown's. I again loop through all the other select options and remove the color on it and also the custom attribute.
Hope this helps.
You can use through combinations of var $opt=$('select>option').clone() and $('select option[value="'+val+'"').remove().
There is another example: try this. https://jsfiddle.net/sherali/jkw8fxzf/12/
var $secondOption= $('#second-choice>option').clone();
$("#first-choice").change(function() {
var userSelected = $(this).val();
$('#second-choice').html($secondOption);
$('#second-choice option[value="'+userSelected+'"').remove()
});
You will need to remove it and then add it again for Internet Explorer.
To remove:
$("#custcol7 option[value=" + sizeValue + "]").remove();
To add:
$("#custcol7").append( "<option value='sizeValue'>sizeValue</option>" );
Note that you need to have sizeValue also in the option text, to actually see something.
You can also replace the html within the select.
Html:
<input id="Button1" type="button" value="hide option" />
<select id="foo">
<option >stuff</option>
<option >stuff2</option>
</select>
Jquery:
$("#Button1").change(function () {
$('#foo').html('<option >stuff</option>');
});
Not exactly what you want, but perhaps it helps. For smaller dropdowns, it is definitely easier.
In IE 11(Edge), the following code is working.
$("#id option[value='1']").remove();
and to ad back,
$('<option>').val('1').text('myText').appendTo('#id');
meder's solution is what I went with for this, but with a small tweak to prevent it from wrapping an option in a span that was already in a span:
$.fn.hideOption = function() {
this.each(function() {
if (!$(this).parent().is('span')) {
$(this).wrap('<span>').hide();
}
});
};
$.fn.showOption = function() {
this.each(function() {
var opt = $(this).find('option').show();
$(this).replaceWith(opt);
});
};
<html>
<head><script>
$(document).ready(function(){
$("#l1").change(function(){
var selectedId=$("#dl1 option[value='"+$(this).val()+"']").attr("id");
$("#dl2 option[data-id ='"+selectedId+"']").removeAttr('disabled');
$("#dl2 option[data-id !='"+selectedId+"']").attr('disabled','disabled');
$("#l2").val("");
});
});
</script></head>
<body>
<label for="l1">choose country</label>
<input list="dl1" name="l1" id="l1" type='select'>
<datalist id="dl1" name="dl1">
<option value="India" id=1>
<option value="US" id=2>
<option value="Germany" id=3>
</datalist>
<br>
<label for="l2">choose City</label>
<input list="dl2" name="l2" id="l2" type='select'>
<datalist id="dl2">
<option value="New Delhi" id="11" data-id="1">
<option value="Washington DC" id="12" data-id="2">
<option value="Berlin" id="13" data-id="3">
<option value="Mumbai"id="14" data-id="1">
<option value="NewYork" id="15" data-id="2">
<option value="Munich" id="16" data-id="3">
</datalist>
</body>
</html>
You can use this:
$("#custcol7 option[value=" + sizeValue + "]").css({display:'none'});
It works fine on all browsers except Safari and Opera. I'm searching for another best solution :)
I am using simple html code to display a select box when ever i use id attribute for select tag it does not display any item in the list but when ever i remove id attribute it works. but surprisingly the same code works fine in Firefox and Google chrome.
<select id="class_renew" name="class_renew" onchange="class_check()" style="width:310px; height:35px; padding:8px; margin-left:95px;">
<option value="0">Select Your Class</option>
</select>
Help from any one will be appreciated.
Java Script Code
function classInput(data){
var category_vals = document.getElementById("class_renew");
for(var i=0;i<data.length;i++){
category_vals.innerHTML+="<option value='"+data[i].cat+"'>PK-"+data[i].cat+"</option>"
}
}
IDs must match. "class_renew" and "categroy_renew" [sic] are not the same, so of course it won't work ;)
EDIT:
Rather than using .innerHTML, why not do things properly?
category_vals.appendChild(new Option("PK-"+data[i].cat,data[i].cat));
This ensures that you won't have any problems if, for example, any of the items have an apostrophe in them.
I'm working with this jQuery code:
$('#selection').bind("change", function(){
var selected = $(this).find('option:selected');
var datavar = selected.text().toLowerCase();
//alert(datavar);
//alert('looking for '+datavar+$('#test').data(datavar));
//alert($('#test').data('var1'))
});
http://jsfiddle.net/Zwe6h/
The purpose is to choose what data variable you wish to extract from the #test element by using the #selection element. it should alert you as to what the value of that data variable is.
The datavar variable is set correctly as alert(datavar); prints out the correct value.
However, the second test alert (which is the purpose of this test) displays it as undefined. The third test alert simply tests to make sure you can explicitly call the data variables by hard-coding the variable.
I am not understanding why it is coming back with undefined. I tested the type of datavar, and it is indeed a string, so I would expect it to behave just as it would if it were hardcoded. Can someone shed some light on this?
Try this:
alert('looking for '+datavar + $('#test').data($.trim(datavar)));
Issue is with some newline chars (casued by html formatting) in the text selected as they are not included between the option start and end tag. So you just need to trim it.
Fiddle
Or fix your options to include the text in between closing and ending tags.
<select name='selection' id='selection'>
<option value='1'>var1</option>
<option value='2'>var2</option>
</select>
Fiddle2
Working like a switch on Chrome (v27.), FF (v21.), and IE9.
I cannot test on other browsers.
As it doesn't refers to anything else than HTML, I am about to think that it works like this, on any browser. But, I'd like to be sure.
Any help please ?
TO CANCEL SELECTED COLOR :
<select name="transparenceStrips" id="transparenceStrips" size="1" onclick="transpbandeau()">
<option value="transparent">CLICK HERE</option>
</select>
here is the jsfiddle
Is not a typical usage of a select, this UI can confuse users; I think it will be better using a button.
Something like:
HTML:
COULEUR fond page
<input name="colorFond" id="colorFond" class="color1" value="FFFFFF" size="5" onchange="setBack()">
<br>CANCEL :
<button onclick="transp()">CLICK HERE</button>
Code:
function transp() {
document.getElementsByTagName('BODY')[0].style.backgroundColor = "";
}
function setBack() {
document.getElementsByTagName('BODY')[0].style.backgroundColor = '#'+document.getElementById('colorFond').value;
}
Here is a simple fiddle: http://jsfiddle.net/IrvinDominin/gVH3n/3/
is it crossbrowser?
It's not cross browser, try testing it on an Android Chrome, you'll find that it tries to open the options list in addition to resetting the background color.
The other answer had given a better way to do what you want to do.
I have the following code (reproduced in this jsFiddle) that is not working. There are three options in the Type select box. If the first (True/False) is selected I need the first div to be shown, and if the second or third options are chosen then the second div needs to be shown. What is wrong with this code?
HTML:
<form name="editform">
Selector: <select class="selectors" name="1-type" id="1-type">
<option value="tf" selected="selected">True/False</option>
<option value="rd">Radio Button</option>
<option value="chk">Checkboxes</option>
</select>
<div id="seldiv-1">
Good Value: <select name="1-good_value" id="1-good_value">
<option value="true">True</option>
<option value="false">False</option>
</select>
</div>
<div id="textdiv-1" style="display:none;" disabled="disabled">
Good Value:
<textarea name="1-good_value" id="1-good_value"></textarea>
</div>
</form>
Javascript:
$(document).ready(function(){
$('.selectors').on('change',function (){
var arr = $(this).name.split("-");
var id = arr[0];
var val = $(this).val();
if(val=="tf") {
$('#textdiv-'+id).hide();
$('#seldiv'+id).show();
//Make textarea disabled
//Make selection enabled
} else {
$('#textdiv-'+id).hide();
$('#seldiv'+id).show();
//Disable selection
//Enable textarea
}
});
});
Uncaught TypeError: Cannot call method 'split' of undefined.
Change $(this).name.split("-"); to this.name.split("-");
it is not the on but the split function is giving you error, you are trying to get the name method of jquery object which is not available...either you need to use attr() to get the name from jquery object..or use this DOM object to get name
try this
var arr = $(this).attr('name').split("-");
or
var arr=this.name.split('_');
NOTE both your codes inside if/else condition is same.. so you won't notice the difference..check it out in your fiddle
working fiddle example
It 100% does fire, you have an error with $(this).name being undefined. I think what you actually wanted to do there was this.name
jQuery objects don't act just like DOMElement objects, i.e they don't have the same properties (like .name). Next time, open your web console when trying to find out why something doesn't work and you will catch most of your problems there.
This line is your problem:
var arr = $(this).name.split("-");
on is working properly but the line above is throwing an exception.
var arr = $(this).attr("name").split("-");
There are a few ways you could fix this, above is one example.
your problem is when trying to access $(this) which is undefined.
Try just this instead
this.name.split("-");
The name is not a valid property. Rather use id or change the way you access it to var arr = $(this).attr('name').split("-");.
