I developed a dropdown list using the jQuery UI selectMenu widget. Although I developed a drop-down component in the Angular and reused it many times. Now the problem was that I gave the same class name to each of those dropdown lists and I was trying to get the value of the selected option from each of the dropdown lists. Given below is the code.
$(function() {
$.widget("custom.mySelectMenu", $.ui.selectmenu, {
_renderMenu: function(ul, items) {
console.log(items);
var that = this,
currentCategory = "";
ul.parent().prepend("<ul class='ui-header ui-menu ui-corner-bottom ui-widget ui-widget-content'><li class='ui-menu-item'><span class='ui-menu-item-wrapper'>" + "CODE" + "</span><span class='ui-menu-item-wrapper'>" + "DESCRIPTION" + "</span><span class='ui-menu-item-wrapper'>" + "PRICE" + "</span></li></ul>");
$.each(items, function(index, item) {
var li, name, short, price;
if (item.optgroup != currentCategory) {
ul.append(
"<li class='ui-selectmenu-optgroup ui-menu-divider ui-selectmenu-category'>" + item.optgroup + "</li>"
);
currentCategory = item.optgroup;
}
li = that._renderItemData(ul, item);
console.log(ul);
name = li.text();
short = item.element.data("short");
price = item.element.data("price");
// console.log(li, short, price);
li.prepend(
$("<span>", {
class: "short"
}).html(short)
);
li.append(
$("<span>", {
class: "price"
}).html(price)
);
if (item.optgroup) {
li.attr("aria-label", item.optgroup + " : " + item.label);
}
});
}
});
$(".options").mySelectMenu({
width: 300
});
$(".options")
.mySelectMenu("menuWidget")
.addClass("overflow");
});

Now, given below is the jQuery code which I wrote for getting the selected element in each of those dropdown lists.
$('.options').mySelectMenu({
change: function (event, ui) {
console.log($('option:selected').text());
}
});
Now, writing like this printed the values of all the selected options of all the dropdown lists which I don't want but what I wanted was to print the value of only one option of only one dropdown list.
Can anyone suggest how to do that in this case?
$('.options').mySelectMenu({
change: function (event, ui) {
console.log($(this).find('option:selected').text());
}
});
$(this) provides a context to the function and it only selects options from the dropdown you used.
