javascript - How to handle multiple inputs of the same type in a html form? -

-

let's i've got form in can describe family:

<input type="text" name="mother"> <input type="text" name="father"> <input type="text" name="child">

but want people able add infinite number of children form. can use javascript continue adding new inputs more children, wonder how should name these. child1, child2, child3, etc.? , on backend loop on children?

and if children need "age" input field. continue adding fields such child1_age, child2_age, child3_age?

i guess work, have feeling there's smarter way of this. know of better way handle this? tips welcome!

html forms can use arrays input names. example:

<input type="text" name="child[]">
