You have to look if yous select option contains the string you are selecting in your first select element. Then remove it from all other select element except the one you have selected from. That's it.
Try it out,

jQuery :

<pre><code>$("#a").on("change", function(){
 $("select").not(this).children("option:contains(" + $(this).val() + ")").remove();
});
</code></pre>

If you just want to hide the currently selected option in the other selects you can try something like that:

The selected option of the other selects is getting set onload, depending on the default-value of the first select.

<pre><code>$('#b,#c').find('option[value="' + $('#a').val() + '"]').hide(); //Hide the selected on default

selectFirstOption();

$('#a').on('change', function() {
 $('#b,#c').find('option').show();
 $('#b,#c').find('option[value="' + this.value + '"]').hide();
 selectFirstOption();
});

function selectFirstOption(){
 $('#b,#c').each(function(){
 var option = $(this).find('option:visible:first').val(); //Select the first visible option
 $(this).val(option);
 });
}
</code></pre>

based on Amit Joki anser and this post: <a href="https://stackoverflow.com/questions/12750307/jquery-select-change-event-get-selected-option">jquery select change event get selected option</a>

I know the title isn't very descriptive but I hope i can clarify my problem here: I have multiple identical select dropdowns. Now, what I wan't to do is to remove an option from all other dropdowns if it is chosen in one of them. Here is an example:

I have selects with ids 'a', 'b' and 'c'. All of them contain the following options:

<pre><code>&lt;option value='1'&gt;1&lt;/option&gt;
&lt;option value='2'&gt;2&lt;/option&gt;
&lt;option value='3'&gt;3&lt;/option&gt;
</code></pre>

If I now chose option '1' in select list 'a', I want to remove option '1' from lists 'b' and 'c' with JQuery. 

Edit: This is basically all I have: <a href="http://jsfiddle.net/j91p8eo5/" rel="nofollow">http://jsfiddle.net/j91p8eo5/</a>

Anyone got any ideas?

How do I remove a select option from identical select lists 'b' and 'c' if it's chosen in select list 'a'?

我知道标题不是很描述，但我希望我能澄清我的问题:我有多个相同的选择下拉列表。现在，我不想做的是从所有其他下拉列表中删除一个选项，如果它是在其中一个中选择的。下面是一个示例：我有ids 'a‘、'b’和'c‘的选择。所有这些文件都包含以下选项：<option value='1'>1</option><option val...

问如果选择列表'a‘中选择了“b”和“c”，如何从相同的选择列表“b”和“c”中删除选择选项？
