Select multiple html elements by clicking on one element in Jquery

I have two images on my html page and I have one button named MOVE to move them left separately. To move them I have a Jquery function with selected class. I have two input fields each of them belongs to the particular image. My button has a click counter function so I need to get a count by clicking on the same button to both images separately into those two input fields.

I think when I select image 1, It's also should be selected input 1, and then the counter will count image 1's counts of moves and when I select image 2, It's also should be selected input 2, and then the counter will count image 2's counts of moves.

I don't know how to select multiple elements by clicking on one element. please help

My Jquery function

$(document).ready(function() {

$(".plan1").click(function() {                              //medium move
    // unselect others
    $(".plan1").removeClass("selected");
    // reselect this one
    $(this).addClass("selected");
});

$("#b1").click(function() {
    // animate selected
    $(".plan1.selected").animate({left:'+=20px'});
    $('#f1.selected').val(function(i, val) { return +val+1 });
});
});

HTML

<img src="imagesource" class="plan1" />
<img src="imagesource" class="plan1" />

<input type="text" id="f1" />
<input type="text" id="f2" />

<button id="b1">MOVE</button>
