Question:
I have five HTML
selects with different values, but the options have the
same text. How do I compare the text options, instead of the values, and
disable the the respective option in every other select? For example, if I have:
<select name="options[70]" id="select_70">
<option value="1" price="0"> test-1 </option>
<option value="2" price="0"> test-2 </option>
<option value="3" price="0"> test-3 </option>
</select>
<select name="options[71]" id="select_71">
<option value="4" price="0"> test-1 </option>
<option value="5" price="0"> test-2 </option>
<option value="6" price="0"> test-3 </option>
</select>
<select name="options[72]" id="select_72">
<option value="7" price="0"> test-1 </option>
<option value="8" price="0"> test-2 </option>
<option value="9" price="0"> test-3 </option>
</select>
<select name="options[73]" id="select_73">
<option value="10" price="0"> test-1 </option>
<option value="11" price="0"> test-2 </option>
<option value="12" price="0"> test-3 </option>
</select>
<select name="options[74]" id="select_74">
<option value="13" price="0"> test-1 </option>
<option value="14" price="0"> test-2 </option>
<option value="15" price="0"> test-3 </option>
</select>
Suppose the user
selects the option test-1 in the last select. This should disable the corresponding option in the other selects. How can I achieve that?
ANSWERS:
If I understand you properly,
this might be it:
var $selects = $('select');
$selects.on('change', function() {
var $select = $(this),
$options = $selects.not($select).find('option'),
selectedText = $select.children('option:selected').text();
var $optionsToDisable = $options.filter(function() {
return $(this).text() == selectedText;
});
$optionsToDisable.prop('disabled', true);
});
//to apply initial selection
$selects.eq(0).trigger('change');

Answer2:
A length example
var $selects = $('select');
available = {};
// Get the text of options from the dropdown
// and store in a object hash
$('option', $selects.eq(0)).each(function (i) {
var val = $.trim($(this).text());
available[val] = false;
});
$selects.change(function () {
var $this = $(this);
var selectedVal = $.trim($this.find('option:selected').text());
// set that value to true
available[selectedVal] = true;
$selects.not(this).each(function () {
$('option', this).each(function () {
var optText = $.trim($(this).text()),
optCheck = available[optText];
$(this).prop('disabled', optCheck );
});
});
}).change(); // Trigger once to add options at load of first choice
ANSWER 3:
Expanding
on @IgorDymov's answer (credit should go to him), here's probably what I'd do
(seefiddle):
var $selects = $('select');
$selects.on('change', function() {
$("option", $selects).prop("disabled", false);
$selects.each(function() {
var $select = $(this),
$options = $selects.not($select).find('option'),
selectedText = $select.children('option:selected').text();
$options.each(function() {
if($(this).text() == selectedText) $(this).prop("disabled", true);
});
});
});
$selects.eq(0).trigger('change');
That way we completely refresh the selections each time a new
one is made, which means properties become re-enabled again. You'll notice in
the fiddle I reduced the number of selects and increased the number of options
so that you don't get trapped in a situation where all options are disabled at
the same time, I think that makes most sense.
