Programmatically clicking all buttons on a page in Chrome's console

Well, you want to make sure you only select the buttons in the section so you are not running the search.

$("#body .btn").trigger("click");

Based on Salketers comment to the question, here's a little script that will programatically click all buttons one by one at a 1 second interval, and also log the clicked button to the console:

var buttons = $("button"), 
    interval = setInterval(function(){
        var btn = $(buttons.splice(0, 1));
        console.log("Clicking:", btn);
        btn.click();
        if (buttons.length === 0) {
            clearInterval(interval);
        }
    }, 1000);

Your class seems to be missing the .. Try one of these:

$(".btn").click();
$("button").click();
$("input:submit").click();
$(".btn.small.info").click();
