I do not know if the right word is buffer but how do you make the JavaScript code "clean" like this:
({"content":"<div id=\"_sub-item\">Espere, ser\u00e1 exibido ap\u00f3s o carregamento dos itens.<\/div>"
Can you see that he has listed all "and coded ready to display to the browser?"
How do you do this with PHP?
