'jquery string to number back to string

Hi I am using PHP 5 as a back end language with Jquery in front end. In one of the database, we have auto generated numbers as a primary key. Now we are calling that number as a id to the div in HTML. But it looks like div doesn't accept number.

Now i want to transfer that number into some string, which i can pass through the div. Again we have to convert that string into same earlier number so that we can query the database.

the html code looks as below

<div id = "something">

<span class = "class1">...</span>
...
...
...
<span class = "class5"> ...</span>


</div>

please note that 

$( "#something").children(".class5").html("response");

doesn't work here since something is integer...hope i am clear

here "something" is a integer which i wish to convert into string. After getting inside div, i want to convert string into the same earlier number.

Now guide me how to convert int to string so that i can put in div ..and then again that string back to same int....

i have two options...to use jquery/javascript ..or through php....thank you

Solution 1:[1]

to convert int to string you can use in javaScript.

var string1 = ""+i;

& for converting string to int go for 

var integ = parseInt(string1);

If I'm reading you right, you want access to the id of the div. Here, something is an integer. It gets converted to a string when you use it - like I have in the example below - to a string for use as the id. Then you can get the id of that div element again inside of the class html using some jQuery and affixing a + to the beginning of it to convert from a string back to an integer.

var something = 1;

$("#" + something).children(".class5").html(function() {
  var id = +$(this).closest('div').attr('id');
  $(this).html('Typeof id: ' + typeof id + id);
});

Fiddle

its pretty simple, do it like this - suppose 

(something) id = 5

in case.

setup the id for the div in php as

$divid = "div".$id

and

$divclass = $id

then pass these to div.

it will become

<div id="div5" class="5" >

do whatever using

$("#div5")

in jquery and when you want the id back use

var id = $("#div5").attr('class');

to convert the numbers to string and vice versa use:

var string = String(1);

and

var num = Number(string);
