About string concatenation I'm still a riddle-like feeling. The foundation is not strong, shake--! The immediate goal is to never make the same mistake again (vomiting blood). ）

Draw a table with Jdgrid, where one column is a custom action column:

The wording of a problem:

1 false , 2     function (cellvalue,options,row) {3     var html = ' <div class= ' operate-box ' > '; 4     HTML + = ' <a href= "javascript:void (0)" onclick= "addorupdate (\ ' +row.id+ ', \ ' +row.type+ ');" > Modify </a> '5    }6 }

The result URL is very strange,

Then the colleague showed up and helped me change it.

Line four: 1 html + = ' <a href= "javascript:void (0)" onclick= "addorupdate (\ ' +row.id+ ' \ ', \ ' +row.type+ ' \ ');" > Modify </a> '

It turns out that my comma is not escaped. No wonder the field on the page is always undefined.
