将数据从jquery HTML方法检索到数组中

Question

I start learning jquery and have the following code to getting the data from my database, it is corrected display what I want from the database in the 'div tag' below

 <script type="text/javascript">
            // function to get data from the database
            function getData()
            {
                $('#num').hide();
                $.post('getData.php',{rev: form.select.value},
                  function(output){
                          $('#num').html(output).fadeIn(700);        
                  });
            }
 </script>
 ....
 <div id="num"></div>
 .......

The jquery html method displays as a string (e.g: 1 2 3). Now I want to save the contents of jquery html method into an array so I can access it for future data usage, is there any way to establish that ? Thanks for your helps !!!

Answer 1

You can use split or JSON.parse here:

Using JSON.parse:

var arr = JSON.parse("[" + output + "]");

output:

[1, 2, 3]

This gives you an Array of numbers.

or

output.split(" ");

Output:

["1", "2", "3"]

This gives you an Array of strings.
