从类选择器获取id而不单击

Question

我想从类选择器中获取id而不点击。

var type_selected = '' ;
$('.type_selected').attr();
type_selected = (this.id);

Answer 1

使用它。这将返回该类的所有元素的数组;

var type_selected = [];
$('.type_selected').each(function(){
    type_selected.push($(this).attr("id"));
});

console.log(type_selected);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<p class="type_selected" id="id1">This is a test<p>
<p class="type_selected" id="id2">This is a test 2<p>
<p class="type_selected" id="id3">This is a test<p>
