Javascript does not refresh the row and column _ javascript skills for table operations

This article mainly introduces the js operation of table rows and columns without refreshing the new implementation. You can refer to the following code for reference only. If you force copy, modify the page id.

The Code is as follows:

// Query the database's Qualified Data
Function SelectAlterNativeVenues (field)

}
Else if (window. ActiveXObject)

}
If (xmlhttp! = Null)
{
