多个图片无法在html中工作的图片弹出窗口

Question

我创建了一个网站，在该网站中以网格格式显示图像。当用户单击图像时，将显示一个弹出窗口，其中单击的图像带有关闭按钮和下面的文本，下面是我的操作

var modals = document.getElementById("memodals");

// Get the image and insert it inside the modals - use its "alt" text as a captions
var img = document.getElementById("l1");
var modalsImg = document.getElementById("img01");
var captionsText = document.getElementById("captions");
img.onclick = function() {
  modals.style.display = "block";
  modalsImg.src = this.src;
  captionsText.innerHTML = this.alt;
}
var img = document.getElementById("l2");
var modalsImg = document.getElementById("img01");
var captionsText = document.getElementById("captions");
img.onclick = function() {
  modals.style.display = "block";
  modalsImg.src = this.src;
  captionsText.innerHTML = this.alt;
}
var img = document.getElementById("l3");
var modalsImg = document.getElementById("img01");
var captionsText = document.getElementById("captions");
img.onclick = function() {
  modals.style.display = "block";
  modalsImg.src = this.src;
  captionsText.innerHTML = this.alt;
}
var img = document.getElementById("l4");
var modalsImg = document.getElementById("img01");
var captionsText = document.getElementById("captions");
img.onclick = function() {
  modals.style.display = "block";
  modalsImg.src = this.src;
  captionsText.innerHTML = this.alt;
}

// Get the <span> element that closes the modals
var span = document.getElementsByClassName("closes")[0];

// When the user clicks on <span> (x), closes the modals
span.onclick = function() {
  modals.style.display = "none";
}

.me {
  border-radius: 5px;
  cursor: pointer;
  transition: 0.3s;
}

.me:hover {
  opacity: 0.7;
}


/* The modals (background) */

.modals {
  display: none;
  /* Hidden by default */
  position: fixed;
  /* Stay in place */
  z-index: 1;
  /* Sit on top */
  padding-top: 100px;
  /* Location of the box */
  left: 0;
  top: 0;
  width: 100%;
  /* Full width */
  height: 100%;
  /* Full height */
  overflow: auto;
  /* Enable scroll if needed */
  background-color: rgb(0, 0, 0);
  /* Fallback color */
  background-color: rgba(0, 0, 0, 0.9);
  /* Black w/ opacity */
}


/* modals Content (image) */

.modals-content {
  margin: auto;
  display: block;
  width: 80%;
  max-width: 700px;
}


/* captions of modals Image */

#captions {
  margin: auto;
  display: block;
  width: 80%;
  max-width: 700px;
  text-align: center;
  color: #ccc;
  padding: 10px 0;
  height: 150px;
}


/* Add Animation */

.modals-content,
#captions {
  -webkit-animation-name: zoom;
  -webkit-animation-duration: 0.6s;
  animation-name: zoom;
  animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
  from {
    -webkit-transform: scale(0)
  }
  to {
    -webkit-transform: scale(1)
  }
}

@keyframes zoom {
  from {
    transform: scale(0)
  }
  to {
    transform: scale(1)
  }
}


/* The closes Button */

.closes {
  position: absolute;
  top: 15px;
  right: 35px;
  color: #f1f1f1;
  font-size: 40px;
  font-weight: bold;
  transition: 0.3s;
}

.closes:hover,
.closes:focus {
  color: #bbb;
  text-decoration: none;
  cursor: pointer;
}


/* 100% Image Width on Smaller Screens */

@media only screen and (max-width: 700px) {
  .modals-content {
    width: 100%;
  }
}

<div style="margin-left:35px;">
  <img class="me" id="l1" src="images\Necklace\03.png" alt="For More Details Contact: 9441394419">
  <img class="me" id="l2" src="images\Necklace\06.png" alt="For More Details Contact: 9441394419">

  <img class="me" id="l3" src="images\Necklace\08.png" alt="For More Details Contact: 9441394419">
  <img class="me" id="l4" src="images\Necklace\10.png" alt="For More Details Contact: 9441394419">
  <div style="margin-top:100px;">

当我仅将代码用于一个图像时，它可以正常工作，但是当我像上述代码那样对多个图像进行操作时，则无法正常工作。谁能告诉我我的代码有什么问题，或者请编辑我的代码并向我显示答案
