Solutions to the conflict between nvelocity and jquery

The solutions when the $ of NVelocity conflicts with the $ of Jquery are as follows:

1. Use jQuery .noConflict.

Such as:

var j = jQuery.noConflict(); j.ajax();

Disadvantages: When using jQuery related plug-ins, the plug-ins will become invalid!

2. Use jQuery instead of $.

For example:

jQuery.ajax();

Disadvantages: Not suitable for expansion. Once replaced with a third-party library, then Sorry for the trouble

3. Wrap the conflict method in jQuery.

If $.ajax() conflicts in Velocity, redefine it as follows:

function dw(){}
dw.ajax=function(s){ jQuery.ajax(s); } dw.ajax();

4. Define a $JQ as $.

You can use ${JQ}AJAX in js in the future.

Write this (definition) at the front desk:

#set($JQ="$.")
