弹性框图像选择

Question

我在响应式弹性网格中有一个包含四个图像的窗口。我想在单击图像时，这个图像得到width=100% 覆盖（或隐藏）其他图像总是在弹性框中。

我猜是使用 jQuery 和 JavaScript，但我找不到方法。有什么帮助吗？

谢谢。

我对您的 HTML 结构做了一些更改。运行下面的 sn -p

var classname = document.getElementsByClassName("photoContainer");
	var containerWidth = document.getElementsByClassName('container')[0].offsetWidth;

	var myFunction = function(ev) {
  
  if(this.classList.contains('expandImage')) {
  this.classList.remove('expandImage');
  for (var i = 0; i < classname.length; i++) {
	    	classname[i].classList.remove('hideImage');
		}

  return;
  }
		
		for (var i = 0; i < classname.length; i++) {
	    	classname[i].classList.add('hideImage');
		}
		this.classList.remove('hideImage');
		this.classList.add('expandImage');
	    this.style.width = containerWidth;
		

	};

	for (var i = 0; i < classname.length; i++) {
	    classname[i].addEventListener('click', myFunction, false);
	}

.wrap {
	display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
}

.container
{box-shadow: 0.075rem 0 0 0 #C9C9C9,0 0.075rem 0 0 #C9C9C9,0.075rem 0.075rem 0 0 #C9C9C9, 0.075rem 0 0 0 #C9C9C9 inset,0 0.075rem 0 0 #C9C9C9 inset;
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
float:left;
position: relative;}

.half
{margin: 0.25rem;}

.photo {width: 15rem;
max-width:100%;
}

.hideImage {
	display: none
}

.expandImage > img {
    width: 100%;
}
