this oneのような画像ズームエフェクトを作成しようとしています。私はprefixfree.jsというプラグインを検索してコード内で試してみましたが、うまくいきませんでした。イメージを表示していましたが、マウスを置くと画像のズーム効果はありません。jqueryを使用して画像のズーム効果を作成する方法は？
プラグインのリンクはthisです。 thisのように動作するはずです。
さらに詳しい情報については、大きな画像のサイズは1406X1275で、小さな画像は200X200です。この問題を解決するために私を助けてください。
$(document).ready(function() {
var native_width$ = 0;
var native_height = 0;
$(".magnify").mousemove(function(e) {
//When the user hovers on the image, the script will first calculate
//the native dimensions if they don't exist. Only after the native dimensions
//are available, the script will show the zoomed version.
if (!native_width && !native_height) {
//This will create a new image object with the same image as that in .small
//We cannot directly get the dimensions from .small because of the
//width specified to 200px in the html. To get the actual dimensions we have
//created this image object.
var image_object = new Image();
image_object.src = $(".small").attr("src");
//This code is wrapped in the .load function which is important.
//width and height of the object would return 0 if accessed before
//the image gets loaded.
native_width = image_object.width;
native_height = image_object.height;
} else {
//x/y coordinates of the mouse
//This is the position of .magnify with respect to the document.
var magnify_offset = $(this).offset();
//We will deduct the positions of .magnify from the mouse positions with
//respect to the document to get the mouse positions with respect to the
//container(.magnify)
var mx = e.pageX - magnify_offset.left;
var my = e.pageY - magnify_offset.top;
//Finally the code to fade out the glass if the mouse is outside the container
if (mx < $(this).width() && my < $(this).height(&& mx > 0 && my > 0) {
$(".large").fadeIn(100);
} else {
$(".large").fadeOut(100);
}
if ($(".large").is(":visible")) {
//The background position of .large will be changed according to the position
//of the mouse over the .small image. So we will get the ratio of the pixel
//under the mouse pointer with respect to the image and use that to position the
//large image inside the magnifying glass
var rx = Math.round(mx/$(".small").width() * native_width - $(".large").width()/2) * -1;
var ry = Math.round(my/$(".small").height() * native_height - $(".large").height()/2) * -1;
var bgp = rx + "px " + ry + "px";
//Time to move the magnifying glass with the mouse
var px = mx - $(".large").width()/2;
var py = my - $(".large").height()/2;
//Now the glass moves with the mouse
//The logic is to deduct half of the glass's width and height from the
//mouse coordinates to place it with its center at the mouse coordinates
//If you hover on the image now, you should see the magnifying glass in action
