if I have this:
function add(){ var val = document.getElementById("item").value; document.getElementById("items").value = val; }
<table> <input type="text" name="item" id="item" value="" > <input type="hidden" name="items[]" id="items[]" value="" > <button onclick="add()" type="button"> Add</button> </table>
so I just want add some values to input items[], It's possible? in javascript I use push(), but in this case I don't know what to do.
You should create a new items[]
element for each value that you're adding. Then the middleware on the server should automatically create an array with all these values.
function add(){ var val = document.getElementById("item").value; var item = document.createElement("input"); item.type = "hidden"; item.name = "items[]"; item.value = val; document.getElementById("form").appendChild(item); }
<form id="form"> <input type="text" name="item" id="item" value=""> <button onclick="add()" type="button"> Add</button> </form>
