我正在尝试在鼠标悬停时缩放图像,但缩放仅适用于第一个图像。
我在我的 django 模板中使用给定的代码来缩放图像。
{% for image in images_obj %}
<img class="drift-demo-trigger" data-zoom="{% static
'/images/catalog/products/thumbnail/' %}{{image}}" src="{% static
'/images/catalog/products/thumbnail/' %}{{image}}" alt="IMG-PRODUCT"
style="width:99%;border:1px solid #ccc;">
<div class="detail">
<section>
</section>
</div>
{% endfor %}
new Drift(document.querySelector('.drift-demo-trigger'), {
paneContainer: document.querySelector('.detail'),
inlinePane: 900,
inlineOffsetY: -85,
containInline: true,
hoverBoundingBox: true
});
所有循环播放的图像都应缩放,但目前只有第一个图像能够缩放。
在你的 html 代码之前试试这个:
<style>
* {box-sizing: border-box;}
.img-zoom-container {
position: relative;
}
.img-zoom-lens {
position: absolute;
border: 1px solid #d4d4d4;
/*set the size of the lens:*/
width: 80px;
height: 80px;
}
.img-zoom-result {
border: 1px solid #d4d4d4;
/*set the size of the result div:*/
width: 400px;
height: 400px;
}
</style>
<script>
function imageZoom(imgID, resultID) {
var img, lens, result, cx, cy;
img = document.getElementById(imgID);
result = document.getElementById(resultID);
/*create lens:*/
lens = document.createElement("DIV");
lens.setAttribute("class", "img-zoom-lens");
/*insert lens:*/
img.parentElement.insertBefore(lens, img);
/*calculate the ratio between result DIV and lens:*/
cx = result.offsetWidth / lens.offsetWidth;
cy = result.offsetHeight / lens.offsetHeight;
/*set background properties for the result DIV:*/
result.style.backgroundImage = "url('" + img.src + "')";
result.style.backgroundSize = (img.width * cx) + "px " + (img.height * cy) + "px";
/*execute a function when someone moves the cursor over the image, or the lens:*/
lens.addEventListener("mousemove", moveLens);
img.addEventListener("mousemove", moveLens);
/*and also for touch screens:*/
lens.addEventListener("touchmove", moveLens);
img.addEventListener("touchmove", moveLens);
function moveLens(e) {
var pos, x, y;
/*prevent any other actions that may occur when moving over the image:*/
e.preventDefault();
/*get the cursor's x and y positions:*/
pos = getCursorPos(e);
/*calculate the position of the lens:*/
x = pos.x - (lens.offsetWidth / 2);
y = pos.y - (lens.offsetHeight / 2);
/*prevent the lens from being positioned outside the image:*/
if (x > img.width - lens.offsetWidth) {x = img.width - lens.offsetWidth;}
if (x < 0) {x = 0;}
if (y > img.height - lens.offsetHeight) {y = img.height - lens.offsetHeight;}
if (y < 0) {y = 0;}
/*set the position of the lens:*/
lens.style.left = x + "px";
lens.style.top = y + "px";
/*display what the lens "sees":*/
result.style.backgroundPosition = "-" + (x * cx) + "px -" + (y * cy) + "px";
}
function getCursorPos(e) {
var a, x = 0, y = 0;
e = e || window.event;
/*get the x and y positions of the image:*/
a = img.getBoundingClientRect();
/*calculate the cursor's x and y coordinates, relative to the image:*/
x = e.pageX - a.left;
y = e.pageY - a.top;
/*consider any page scrolling:*/
x = x - window.pageXOffset;
y = y - window.pageYOffset;
return {x : x, y : y};
}
}
</script>
现在在 html 中:
{% extends 'base.html' %}
{% block content %}
<div class="col-md-12"style="margin-left: 0px">
<div class="panel-body">
<table class="table-responsive">
<tbody>
<tr>
<td><div class="img-zoom-container">
<img id="myimage" src="{{ member.immagine.url }}" width="860" >
</div></td><td>
<div id="myresult" class="img-zoom-result"></div></td></tr>
</tbody>
</table>
<br>
<script>
// Initiate zoom effect:
imageZoom("myimage", "myresult");
</script>
</div>
</div>
</div>
</div>
{% endblock %}
