bind javascript event for future element without attaching any event - DOMNodeInserted (alternative of .on )

1st approach what we did always 

$('body').on('click','.abcd',function () {
        $(this).prev('.teaseRestText').toggle();
        if ($(this).attr('toggle') == '0') {
            $(this).html('Show Less...').attr('toggle', 1);
        }
        else {
            $(this).html('Show More...').attr('toggle', 0);
        }
});

But sometimes, situation came that we don't have any event like "click " but still need a function to execute for dynamic elements. 

I came to this solution  

$(document).bind('DOMNodeInserted', function(event) {
    $('#table tr').each(function (e) {
        console.log(e);
    });
});

Add Decimal in your amount at desire position

Code

$amount = 560;
$decimalPosition = 2;
$divideBy   =   pow(10, $decimalPosition );
$newNumber  =   number_format( $totalTax / $divideBy , 2, '.','');
echo $newNumber;

OutPut
5.60

Second Way

        $decimal_point = 2;
        $totalTax=1260; //1.260

        $a=substr($totalTax,0,-$decimal_point); //560 ka 5
        $b=substr($totalTax,-$decimal_point,$decimal_point); //560 ka 60
        
        $c = $a.'.'.$b;
        echo $c;
        

Third Way

        /********* in one line ****************************************\
        
        $d = (substr($totalTax,0,-$decimal_point)).'.'.(substr($totalTax,-$decimal_point,$decimal_point));

How to Deploy Symfony 2.8 or 3.0 Project on Linux Hosting Server.

After spending several day finally i success to launch my symfony project on share hosting.
Guys ! Its very diffrent to work in xampp / Wamp than Production server in symfony case.

I will tell you story step by step.
I developed a small project in symfony 2.8 which need some ajax call, some CRUD operation.
that project was running like a charm at my localhost. Then finally I upload all files into my shared server under  "public_html" (which turn wrong for me). using this method, some time my page was blank or some time i was geeing un-understandable  error :-).

Finally i got one solution to that work for me on Linux shared hosting .

Follow Below steps

• Before uploading any thing delete everything under "App/Chache"
• upload "WEB" folder which is inside of  your symfony Project  into "/public_html"
• Now Go up one label from /public_html. you  will see  "/"  in remote site path 
• upload all Remain Folders of your symfony project here. 
• Never forgot to update your DB Details in " app/config/parameters.yml" 

Thats it. Go to the url, you will must see the running page.

Note-: i will brief you my Shared Hosting Details which i performed.

•            Server -: Linux
•            Type -:    Share hosting at Hioxindia pvt ltd
•            Framework version-: Symfony 2.8
•            Localy developed with  Wamp + PHPMyadmin
