javascript - 在 Javascript 中访问目标按钮

问题描述

我想使用 jQuery 定位以下按钮

<button id="mybutton" 
        book_title="{{$book->title}}"
        author="{{$book->author}}"
        idx="{{$book->id}}"
        class="btn btn-success b_r_20 btn-xs pull-right"
        >
    Borrow
</button>

单击按钮后，我想显示一个alert().

这是我的HTML

<div class="row">
    <div class="col-lg-8 col-12 m-t-35" >
        @foreach($books as $book)
            <div class="bg-white section_border ">
                <div class="row" >
                    <div class="col-md-3 col-12 center">
                        <img src="{{URL::to($book->photo)}}" style="height: 180px;width: auto; padding-left: 5px;">
                    </div>
                    <div class="col-md-9" >
                        <h4 class="m-t-10">
                            {{$book->title}}
                        </h4>
                        <h5 class="m-t-5">
                            Author: {{$book->author}}
                        </h5>
                        <h5 class="m-t-5">

                        </h5>
                        @if(Auth::user()->role == "Manager" || Auth::user()->role == "Staff")
                            <h5 class="m-t-5">
                                Shelve: {{$book->shelve->title}}
                            </h5>
