将具有相同类名的表单输入字段放入数组中

Question

So I have some fields like this:

[1] [2] [3] with attributes: name=item1,item2,item3 and class = item

What I want to do is get all three fields into an array:

so:

array = [1,2,3];

Is there a way to do this using the unique class attribute: "item" ?

Answer 1

You can use Array.map() method to return an array out of attribute:

 var items = $('.item').attr('name').split(','), // convert to array arr = [].map.call(items, function(value) { // use return +value.match(/\\d/)[0]; // return the number value from the array "items" }); $('pre').html(JSON.stringify(arr)); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <p name='item1,item2,item3' class='item'>item</p> <pre></pre> 

Answer 2

Get the items and loop through them. Adding each one to your list.

var items = [];
$('.item').each(function(index, value){
  //where value is an input
  items.push(value);
});

Answer 3

试试这个$(".items").toArray()以获得相同的结果，可能是可行的。
