本文介绍了如何使硬编码/重复jQuery语法和压缩成为动态的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个带有一些jQuery代码的网页.现在,我正在对jQuery语法进行硬编码,以适应数据库表中7行的更新,并预计还会有3行左右的增长.但是我不想每天检查我的应用程序,以查看数据库表是否已超过10行,然后必须添加更多的硬编码jQuery语法.

I have a web page with some jQuery code. Right now I am hardcoding my jQuery syntax to accommodate for updates to 7 rows in a DB Table and also to anticipate growth of about 3 more rows. But I don't want to check my app daily to see if the DB Table has grown beyond 10 rows and then have to add more hardcoded jQuery syntax.

谁能帮助我使用我的jQuery并将其压缩为真正的动态-从而消除它的硬编码性质并使其能够处理任意数量的行?谢谢.

Can anyone help me take my jQuery and condense it to be truly dynamic -- thus removing the hardcoded nature of it and enable it to handle any number of rows? Thanks.

推荐答案

演示 —很抱歉,您的代码很糟糕.

DEMO — Sorry to say this, but your code is poor.

以下是jQuery的替代品,没有更改您的任何HTML,除了用<div class="content-wrapper"></div>包装添加新位置"行.

Following is the jQuery replacement without changing any of your HTML, except for wrapping the "Add a new location" row with <div class="content-wrapper"></div>.

$('.icons a').on('click', function(){
    var $contentWrapper = $(this).closest('.content-wrapper');
    var $siblings = $contentWrapper.siblings('.content-wrapper');
    $siblings.find('.hide').hide('slow');
    $siblings.find('.show').show('slow');
    $contentWrapper.find('.show').toggle();
    $contentWrapper.find('.hide').toggle().find('.textbox').focus();
});

别忘了将上述jQuery包装在$(function(){ ... });中,以便仅在DOM准备好后才执行.

Don't forget to wrap the above jQuery in $(function(){ ... }); so that it only executes once the DOM is ready.
