如何在JQuery中对.html使用通配符？

Question

How can I use a wild card to update divs?

I want to change two sets of divs (one has additional information at the end).
I am using an each loop and do not want to do any sort of searching or find. I know the beginning is the same for all the divs.

Want to change this one as well: '#div\\\\\\:'+month+'\\\\\\:'+day+'\\\\\\:'+time+'\\\\\\:'+additionalInfo;

First Div Type

div:2:25:1530

Second Div Type

 div:2:25:1530:3065

Code:

var div = '#div\\\:'+month+'\\\:'+day+'\\\:'+time;
$(div).html('<a class="btn btn-block btn-custom">TEST</a>');

I use the triple slash because the double was not working for some reason. But worked when I added the third, not sure why.

You can use one of the attribute selectors to target multiple divs with a similar id or class name - there really isn't one for regexp

For example, say you have a div ID of <div id="div:01:01:2015:info1"></div> , you can target it with this selector:

Starts with selector ^=

// target all divs for January (assuming mm:dd:yyyy)
$('[id^="div\\:01"]')

Contains selector *=

// target all divs for 2015
$('[id*="2015"]')

etc

Update: Use two backslashes \\\\ to escape meta characters
