A small problem in the development process. Mark it as a record.

I wrote something two days ago and used some jquery stuff. The function is to obtain the text on a fixed column in the row based on a row in the double-click table to obtain the row number, then it is uploaded back to the selected text box in the parent form. At first, I passed the row index test and found that I could locate the index, so I didn't think much about it. However, from Monday to Shanxi, I called my colleagues on the customer's system to say that something went wrong. The passed value is not unique. After I told my colleagues about my ideas, he checked them again.CodeThe problem is found on the passed row index. Due to the limited data volume during local testing, this problem cannot be exposed. The problem is: when the data volume exceeds 10 rows, this problem will be exposed. For example, if the row passed is 2 and the column index is 3, normally, it is the text of the cell <span> in the third column of the second row. However, when 23 rows are passed, it will not work and it will be repeated. At this time, the value is not unique. Therefore, this is a matter of detail. The solution is to separate row and column index with underscores. This ensures data uniqueness. This is the details. I think it is necessary to mark it.
