JQuery将div ID转换为索引 [英] JQuery convert div ID to index

问题描述

大家好，



请帮帮忙？



我有一把JQuery手风琴，想要以编程方式打开基于选项卡ID的特定选项卡。我觉得我需要在手风琴中获得带有所需ID的div的索引（？），然后调用

 $（ ＃accordion）。accordion（{active：numberOfDivToOpen}）; 

问题是，如何在手风琴中获得正确的div数，我从API中了解到我可以打开手风琴标签关于它的0指数编号？



例如：

 < span class =code-keyword><   div     id   =  accordion >  
 <   h3  > 比勒陀利亚信息<   / h3  >  
 <   div     id   = 比勒陀利亚 > 一些文字<   / div  >  
 <   h3  > 约翰内斯堡信息<   / h3  >  
 < span class =code-keyword><   div     id   =  johannesburg > 某些文字<   / div  >  
 <   / div  >  

 $（ ＃accordion）。accordion（{active：  #pretoria}）; 

提前谢谢！

解决方案

（ ＃accordion）。accordion（{active：numberOfDivToOpen}）;

 < span class =code-keyword><   div     id   =  johannesburg > 一些文字<   / div  >  
 <   / div  >  

（ ＃accordion）。accordion（{active：< span class =code- string> #pretoria}）;

Hi all,

Please help?

I have a JQuery accordion, and would like to programmatically open a specific tab based on the ID of the tab. I feel that I need to get the index(?) of the div with the required ID in the accordion, and then call

$("#accordion").accordion({active: numberOfDivToOpen});

The problem however is, how do I get the correct number of the div in the accordion, as I understand from the API that I can open accordion tabs based on its 0-index numbering?

example:

<div id="accordion">
<h3>Pretoria info</h3>
<div id="pretoria">some text</div>
<h3>Johannesburg Info</h3>
<div id="johannesburg">some text</div>
</div>

$("#accordion").accordion({active: "#pretoria"});

Thank you in advance!
