Solution to the $ conflict between jquery and velocity variables in html files_jquery

Problem description:

When using jquery in an environment using velocity template engine, such as: $.fullCalendar.gcalFeed('http://www.google.com/calendar/feeds /sfzc1@realintelligence.com/public/basic')

where $ conflicts with $ in the velocity variable.

Solution:

Define a velocity variable: #set($jquery="$.") Then: ${jquery}fullCalendar.gcalFeed('http: //www.google.com/calendar/feeds/sfzc1@realintelligence.com/public/basic'), using the replacement principle of the veloctiry template engine, the html code is compiled for the first time into $.fullCalendar.gcalFeed('http:// www.google.com/calendar/feeds/sfzc1@realintelligence.com/public/basic'), after being replaced, it was compiled twice and there was no problem with the code.

To sum up, the above answers a truth: "To untie a bell, one needs to tie it."
