Javascript 显示/隐藏按钮：将按钮图标从 FontAwesome 更改为图像

Question

I need to change Font Awesome icons to static images. The icons are used as buttons to show/hide text. I tried to add a working snippet but it wouldn't function correctly - maybe because this is calling FontAwesome - so here is the functioning website instead and code below: http://puredentalcentre.co.uk/about.html

(I've never used Javascript before and did not build this site - I just need to make this change. Using my basic HTML/CSS knowledge, I have attempted changes but they have resulted in the show/hide button no longer working!)

This is the current Javascript:

const elements = document.querySelectorAll(".profile");
elements.forEach((e => {
let l = e.querySelector(".profile button"),
    t = e.querySelector(".profile button i");
var r = e.lastElementChild,
    c = document.querySelectorAll(".profile .profile-desc");
l.addEventListener("click", (() => {
    c.forEach((e => {
        let l = e.parentElement.querySelector("button i");
        r !== e && (e.classList.add("hideText"), l.className = "far fa-plus-circle")
    })), r.classList.toggle("hideText"), "far fa-plus-circle" === t.className ? t.className = "far fa-minus-circle" : t.className = "far fa-plus-circle"
}))
}));

This is how the current HTML calls the button:

This is my attempt, but it results in just the plus-circle_250px.png showing without being clickable so the text is not revealed as in the original code:

var path = "img/"
var pathEls=document.querySelectorAll(".profile");
elements.forEach((e=>{
let l=e.querySelector(".profile button"),
t=e.querySelector(".profile button img");
var r=e.lastElementChild,
c=document.querySelectorAll(".profile .profile-desc");
l.addEventListener("click",(()=>{
c.forEach((e=>{
let l=e.parentElement.querySelector("button img");
r!==e&&(e.classList.add("hideText"),l.className="plus-circle_250px.png")})),r.classList.toggle("hideText"),"plus-circle_250px.png"===t.className?t.className="minus-circle_250px.png":t.className="plus-circle_250px.png"}))}));

How do I swap out the far fa-plus-circle and far fa-minus-circle for my two replacement images plus-circle_250px.png and minus-circle_250px.png ?

Answer 1

A little help:-)

 var path = "https://i.stack.imgur.com/"; var profileEls = document.querySelectorAll(".profile"); for (let profileEl of profileEls) { profileEl.addEventListener("click", function () { var imgEl = this.querySelector("button img"); if (imgEl.src.split("/").pop() === "f3oC3.png") { imgEl.src = path + "BUncn.png"; } else { imgEl.src = path + "f3oC3.png"; } }); }

 <div class="profile"> <button><img height="30" src="https://i.stack.imgur.com/f3oC3.png" ></button> </div> <div class="profile"> <button><img height="30" src="https://i.stack.imgur.com/f3oC3.png" ></button> </div> <div class="profile"> <button><img height="30" src="https://i.stack.imgur.com/f3oC3.png" ></button> </div>

Answer 2

Try with the following snippet:

const elements = document.querySelectorAll(".profile");
elements.forEach((e=>{
    let l = e.querySelector(".profile button")
      , t = e.querySelector(".profile button img");
    var r = e.lastElementChild
      , c = document.querySelectorAll(".profile .profile-desc");
    l.addEventListener("click", (()=>{
        c.forEach((e=>{
            let l = e.parentElement.querySelector("button img");
            r !== e && (e.classList.add("hideText"),
            l.src = "img/plus-circle_250px.png")
        }
        )),
        r.classList.toggle("hideText"),
        "img/plus-circle_250px.png" === t.getAttribute('src') ? t.src = "img/minus-circle_250px.png" : t.src = "img/plus-circle_250px.png"
    }
    ))
}
));

 const elements = document.querySelectorAll(".profile"); elements.forEach((e=>{ let l = e.querySelector(".profile button"), t = e.querySelector(".profile button img"); var r = e.lastElementChild, c = document.querySelectorAll(".profile.profile-desc"); l.addEventListener("click", (()=>{ c.forEach((e=>{ let l = e.parentElement.querySelector("button img"); r.== e && (e.classList,add("hideText"). l.src = "img/plus-circle_250px,png") } )). r.classList,toggle("hideText"). "img/plus-circle_250px.png" === t?getAttribute('src'). t.src = "img/minus-circle_250px:png". t.src = "img/plus-circle_250px;png" } )) } ));
