Mar*_*out 9 jquery plugins select option jquery-chosen
我把2个元素放在彼此旁边.他们都使用jQuery Chosen插件.
这是代码:
<div class="wrapper">
<select data-placeholder="Number row 1" style="width:350px;" multiple class="chzn-select">
<option value=""></option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
</select>
<select data-placeholder="Number row 2" style="width:350px;" multiple class="chzn-select">
<option value=""></option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>

这是Javascript.jQuery库,最新的Chosen插件和CSS都包含在课程中.
<script>
$('.chzn-select').trigger("liszt:updated");
$('.chzn-select').chosen().change( function() {
var selectedValue = $(this).find('option:selected').val();
$(this).parent().find('option[value="'+ selectedValue +'"]:not(:selected)').attr('disabled','disabled');
});
</script>

这样的事情应该这样做:
http://jsfiddle.net/musicisair/dq97z/10/
// cache selects for use later
var selects = $('.chzn-select');
// whenever the selection changes, either disable or enable the
// option in the other selects
selects.chosen().change(function() {
var selected = [];
// add all selected options to the array in the first loop
selects.find("option").each(function() {
if (this.selected) {
selected[this.value] = this;
}
})
// then either disabled or enable them in the second loop:
.each(function() {
// if the current option is already selected in another select disable it.
// otherwise, enable it.
this.disabled = selected[this.value] && selected[this.value] !== this;
});
// trigger the change in the "chosen" selects
selects.trigger("liszt:updated");
});
