javascript - How to specify a function function in the data attribute of html5?

Question

Can I specify a function function in the data-* attribute?

For example, if I write like this, I will get an error formatter is not a function:

<th  data-formatter="test3(value, row, index)">field_name_cn</th>

Answer 1

Eval is enough, but I think your way of solving the problem is unreasonable. Why not tell us your needs and see if there is a good solution

Answer 2

is not function：is string

Answer 3

No.data-attribute is still an attribute, its value is just a string.

The function can be converted into a string, but of course it loses the characteristics of the function

Answer 4

Speaking of which, you can eval and execute the string as a function code

Answer 5

But if you use vue or react framework, you can solve this problem. But this is pure html, it won’t work
