Question

jQuery(document).ready(function($) {
        var devices = $(".menu-item-custom").map(function() {
            return this.id.substr(10);
        }).toArray();

        $.each(devices, function() {

            $("#menu-item-settings-"+this+" .description").eq(3).after("<p class='description description-thin'><label for 'translated_title_"+this+"_ar'>عربي<br><input type= 'text' class='widefat edit-menu-item-title' name='translated_title_"+this+"_ar value='"+$(document).write('ssss')+"' '></label></p>");

        });

});

Using this code I’m trying to write into the value attribute, but this error appears:

Uncaught TypeError: Object [object Object] has no method 'write'

Answer 1

The error is that there’s no write function on $(document) (which is not the same as document).

But perhaps more to the point, you’re creating a string to pass to .after. That’s no place to be writing to the document. The following will suffice, for creating a string:

value='" + 'ssss' + "'

(assuming 'ssss' will in production code be a variable, otherwise there is of course no need for concatenation at all)
