To get Select element you can use $('#first').val();
要获取Select元素,您可以使用$('#first')。val();
To get the text of selected value - $('#first :selected').text();
获取所选值的文本 - $('#first:selected')。text();
Can you please post your select2()
function code

This solution allows you to forget select element. Helpful when you do not have an id on select elements.
此解决方案允许您忘记选择元素。如果您没有选择元素的ID,则会很有帮助。
$("#first").select2()
.on("select2:select", function (e) {
var selected_element = $(e.currentTarget);
var select_val = selected_element.val();
});

If you are using ajax, you may want to get updated value of select right after the selection.
如果您使用的是ajax,则可能需要在选择后立即获取select的更新值。
//Part 1
$(".element").select2(/*Your code*/)
//Part 2 - continued
$(".element").on("select2:select", function (e) {
var select_val = $(e.currentTarget).val();
console.log(select_val)
});

See this fiddle.
Basically, you want to get the value
s of your option
-tags, but you always try to get the value of your select
-node with $("#first").val()
.
看到这个小提琴。基本上,您希望获取option-tags的值,但是您总是尝试使用$(“#first”)。val()获取select-node的值。
So we have to select the option-tags and we will utilize jQuerys selectors:
所以我们必须选择选项标签,我们将使用jQuerys选择器:
$("#first option").each(function() {
console.log($(this).val());
});
$("#first option")
selects every option
which is a child of the element with the id first
.
$(“#first option”)选择每个选项,该选项是id为first的元素的子元素。

Other answers wasn't working for me so i developed solution:
其他答案对我不起作用,所以我开发了解决方案:
I created option with class="option-item" for easy targeting
我使用class =“option-item”创建了选项,以便轻松定位
HTML :
HTML:
<select id="select-test">
<option value="5-val" id="first-id" class="option-item"> First option </option>
</select>
Then for every selected option i added display none property
然后,对于每个选定的选项,我添加了display none属性
CSS:
CSS:
option:checked {
display: none;
}
Now we can add change to our SelectBox to find our selected option with display none property by simple :hidden attribute
现在我们可以添加更改到我们的SelectBox,通过simple:hidden属性找到我们选择的display none属性选项
JQuery:
JQuery的:
$('#select-test').change(function(){
//value
$('#select-test').find('.option-item:hidden').val();
//id
$('#select-test').find('.option-item:hidden').attr('id');
//text
$('#select-test').find('.option-item:hidden').text();
});
