包含错误的简短JQuery代码-有什么问题？

Question

I am trying to use a script to get the masonry effect. I'm using script I've found on https://masonry.desandro.com/v2/docs/intro.html

$(function() {
  $("#new").masonry({
    itemSelector: ".element",
    columnWidth: function(containerWidth) {
      return containerWidth / 2;
    }
  });
});

This is a small part of my site but it turns out that the script has some error because the other scripts in my scripts file stop working. If I remove this piece of code everything goes back to normal.

I don't know if it is important but my file (scripts.js) looks something like this:

/** Function 1 **/
 $(function() {
 ...

/** Function 2 **/
 $(function() {
 ...

/** Function 3 **/
 $(function() {
 ...

I was trying to use some JS validators but it didn't help.

From the look of your sample containerWidth is not defined.

Edit: the comments are correct ignore this, it's wrong
