我正在尝试从选择框中获取自定义属性值。它是由我已经工作的复选框单击触发的。我可以很好地获得名称和值对。我想从选项值行中获取自定义属性(治疗)(强度)(重量)和(障碍)。这可能吗?
选择框
<option value="2220" therapy="1" strength="1" weight="0" obstacle="0">Supine Calf/Hamstring Stretch</option>
<option value="1415" therapy="0" strength="0" weight="0" obstacle="0">Sitting Chair Twist</option>
<option value="1412" therapy="0" strength="0" weight="0" obstacle="0">Static Abductor Presses</option>
jQuery
// exercise list filter category
jQuery.fn.filterByCategory = function(checkbox) {
return this.each(function() {
var select = this;
var optioner = [];
$(checkbox).bind('click', function() {
var optioner = $(select).empty().scrollTop(0).data('options');
var index=0;
$.each(optioner, function(i) {
var option = optioner[i];
var option_text = option.text;
var option_value = parseInt(option.value);
$(select).append(
$('<option>').text(option.text).val(option.value)
);
index++;
});
});
});
};
