问题 I have a jQuery id like <div id="myid-page-top-0"> some stuff </div> I want to use jQuery to grab the "0" from the end of the #id . I have tried like $('div').slice(-1,0); But this doesn't work ? Any ideas ? 回答1: Instead of slice, which would only work if your id contains numbers 0-9, not if it is say 10 or 11, you should base it off of the dashes. Something like: var id = "myid-page-top-0"; alert(id.split("-")[3]); or in your code something like: var number = $('div').attr('id').split("-")[3

My question is, is there a way to do the trim automatically without specifying the fields individually? I know of the configuration option:

问题 <%=CMSStringUtility.toTitleCase(attrValues.getDisplayLabel())%> this returns a string with a leading white space character that I need to remove. I believe this is JAVA in a jsp file.

I made a php function that trims the characters, but it doesn't take into account the html tags. If the trim function

问题 Using boost spirit, I'd like to extract a string that is followed by some data in parentheses. The relevant string is separated by a space from the opening parenthesis. Unfortunately, the string itself may contain spaces. I'm looking for a concise solution that returns the string without a trailing space. The following code illustrates the problem: #include <boost/spirit/include/qi.hpp> #include <boost/spirit/include/phoenix_operator.hpp> #include <string> #include <iostream> namespace qi =

问题 How can we use substring, trim, length operations on some text of blob datatype. And how can we update a column of blob datatype using query? Thanks, 回答1: With difficulty! First of all, which of the 4 various types of blob are you discussing: BYTE TEXT BLOB CLOB These come in pairs (like Sith Lords): there is a binary version (BYTE, BLOB) and a text version (TEXT, CLOB). There's also another pairing: old (BYTE, TEXT) and newer (BLOB, CLOB). The BYTE and TEXT types were introduced with
