动态分配ID [英] Dynamically assign ID

问题描述

我正在使用nodejs和expressjs.

I am using nodejs and expressjs.

我从数据库加载列表.选择任何列表元素都会弹出一个覆盖图，用于编辑和删除所选项目.我不知道如何将所选列表项发送到快递路线.

I load a list from a database. Selecting any of the list elements bring up an overlay with to EDIT and DELETE the selected item. I can not figure out how to send the selected list item to the express route.

我认为需要完成的工作:动态地向叠加层上的按钮分配一个ID.我试图做一个小提琴，但覆盖无法正常工作.

What I believe needs to be done: Dynamically assign an ID to the buttons on the overlay. I tried to make a jfiddle but the overlay would not work.

有什么想法吗?我正在使用jquery将叠加层滑入视图.

Any ideas? I am sliding the overlay into view with jquery.

感谢您抽出宝贵的时间阅读此书

Thank you for taking the time to read this

我有一个动态创建的列表，每个项目都带有".recordlongpress"类，并且将其Jquery功能应用于其上.

I have a dynamically created list, each item with the class ".recordlongpress" and I apply this Jquery functionality to it.

    $(document).ready(function(){           
    $('.recordlongpress').bind('tap', function() {
        return;
    });
    $('.recordlongpress').bind('taphold', function() {
        $('#overlay').fadeIn('fast',function(){
            $('#box').animate({'top':'100px'},500);
        }); 

    });
    $('#boxclose').click(function(){
        $('#box').animate({'top':'-100px'},500,function(){
            $('#overlay').fadeOut('fast');
        });
    });

});

哪个显示了我的叠加层，这是通过CSS和此HTML的组合完成的

Which brings up my overlay which is done by a combination of CSS and this HTML

    <div class="overlay" id="overlay" style="display:none;"></div>
    <div class="box" id="box">  
        <a class="boxclose" id="boxclose"></a>
            <button onclick="location.href='/scape/editcustomerform/id'">Edit Contact</button>
            <button onclick="location.href='/scape/deletecustomer/ID'">Delete Contact</button>
            <button>E-mail Customer</button>
            <button>Call Customer</button>
            <button>GPS to Address</button>
            <button>Create Quote</button>
            <button>Create Sales Order</button>
            <button>Create Cash Sale</button>
        </div>
    </div>

我尝试将路径ID附加到我的路线的末尾，但实际上只是使用单词ID.谢谢您的帮助

I have tried to append the path id to the end of my route, but it just literally takes the word id. Thank you for any help

推荐答案

尝试一下:

var box     = document.getElementById('box'),
    buttons = box.getElementsByTagName('button');

for(var i = 0; i < buttons.length; i++){
    buttons[i].id = [ 'my', 'button', 'id', i ].join('-');
}

此外，您可以尝试映射"操作:

Also, you may try to "map" actions:

var box     = document.getElementById('box'),
    buttons = box.getElementsByTagName('button');

var map = [
    'editcustomerform',
    'deletecustomer',
    'emailcustomer',
    'callcustomer',
    'gpstocustomer',
    'createquote',
    'createsalesorder',
    'createcashsale'
];

for(var i = 0; i < buttons.length; i++){
    buttons[i].id = [ 'my', 'button', 'id', i ].join('-');
    buttons[i].onclick = function(){ location.href = [ '/scape', map[i], 'id' ].join('/'); }
}
