Javascript: a function for automatically wrapping custom-length text _ javascript skills

Javascript: a function for auto-wrapping of custom-length text. Many friends always find that some English words may open the original good table and cause deformation during webpage creation, although you can use style = "table-layout: fixed; word-wrap: break-word; word-break: break-all" to solve this problem, however, sometimes the content is hidden due to incomplete display, and the effect of automatic line feed is not achieved.

So I want to write a function like this to fix this defect. This function is very simple, but it only provides a way to solve this problem.

Function fnAddBr (id, iPerLineLen ){.....}
Id is the id of the text block to be modified, and iPerLineLen is the length of each line.
