How to concatenate JavaScript variables into a complexe string with quotes and doubles quotes?

Question

 var id_person_value = 4;

$('#message').load("{{ path('MyBundle_ajax_modal_vote', {'id_person' :"+id_person_value+"})   }}", function() {//..

It should return

$('#message').load("{{ path('MyBundle_ajax_modal_vote', {'id_person' : 4 })   }}", function() {//..

But this returns me : http://mywebsite.com/app_dev.php/+id_person_value+

How could I inject the value correctly?

Thanks a lot for your help!

try it with 3 brackets like : {{{ path(...) }}} – john Smith Nov 14 '13 at 14:24 — john Smith, Nov 14 '13 at 14:24

You can make use of escape characters such as \' to insert single quote inside the string and \" for double quotes

Instead of concatenating things together, which is tedious and error prone, try a formatting function, similar to printf or format in other languages:

str = format("{{ path('MyBundle_ajax_modal_vote', {'id_person' : {0} }) }}", 4)

Unfortunately, there's no such builtin in Javascript, but it's quite easy to write:

function format(str) {
    var args = [].slice.call(arguments, 1);
    return str.replace(/{(\d+)}/g, function($0, $1) {
        return args[$1]
    })
}

See JavaScript equivalent of Python's format() function? for more implementations.

use simple double quotes to start and end of string "". If you want to include any quote or double quote in your string use escape character \ before quote eg you want string as s= hello"world then s= "hello\""+"World" or s="hello"+"\"" + "world"
