jquery Get Element Index

The problem encountered in the last project, want to get the index of the specified TD in the line TR visible column;

Because there are hidden elements under the change TR, the index is taken directly with $ ([' td[name= ' Operation "] '). The value of index () is definitely incorrect;

Check the information, review the use of the next index ([selector|element]) .

Now for example to share the actual.

First on:

Get the index in several different ways:

• Take #bar index in the ol li: $ ("#bar"). index (); Output 0
• Take #bar index in all Li: $ ("#bar"). Index ("Li"); Output 4
• Fetch the index of #bar in all visible Li: $ ("li:visible"). Index ($ ("#bar")); Output 3
