jQuery 获取有 2 个类的元素的类

Question

<button class="update vacancy-submit" tabindex="2">Save</button>

$('.vacancy-submit').click(function(){
    var type = $(this).attr('class').not('.vacancy-submit');
    console.log(type);
});

我正在尝试将按钮的类放入一个变量中，该变量应该显示update而不是update vacancy-submit

Answer 1

如果始终是头等舱:

$('.vacancy-submit').click(function(){
    var type = this.className.split(/\s+/).shift();
    console.log(type);
});
