Given a group of select fields with the same options, SelectUnique will remove an option from the other select fields when it's selected, and put it back when it's changed.
<script type="text/javascript" src="jquery-1.7.0.min.js"></script>
<script type="text/javascript" src="jquery.selectunique.js"></script>
$(selector).selectunique();
SelectUnique requires jQuery 1.7.1 or later. Options without text will be ignored.
$(selector).selectunique({
ignoreOption: function(option) { return option.val() == 'ignore_me_buddy' }
});
Instruct the plugin to not manage the given option. The option
argument passed to the function is a jQuery object.
$(selector).selectunique('refresh');
Refresh the state of the select fields given by selector
.
This is useful of you're adding and/or removing select fields via JavaScript.
var opts = $(selector).selectunique('remaining');
$.each(opts, function() {
console.log('text: ' + this.text + ' value: ' + this.value);
});
An array of remaing options. I.e., options still available for selecting. Returns an empty array if
no options are available. Each element is an HTMLOptionElement
.
var opts = $(selector).selectunique('selected');
$.each(opts, function() {
console.log('text: ' + this.text + ' value: ' + this.value);
});
An array of options that have been selected. Returns an empty array if
no options have been selected. Each element is an HTMLOptionElement
.
While these nodes are currently selected, their selected
property is false
.
