我是 jquery 的新手 我已经使用 Kinetic.js 实现了拖放操作 我在 html 中有一些图像,我将它们传递给 javascript 函数并使它们可拖动..有两组图像..现在我想要让它们在靠近时相互咬合。我是 jquery 的新手,所以我不知道如何将动态 js 图像变量传递到他们已经传递了 img id 标签的 jquery 操作中。此外,我无法弄清楚 jquery 函数的放置位置以及如何..
这是代码..有人请帮忙..
<html>
<head>
<style>
canvas {
border: 1px solid #9C9898;
}
#img
{
position:absolute;
left:700px;
top:150px;
}
#img1
{
position:absolute;
left:800px;
top:150px;
}
</style>
加载 jquery 库
<script src="kinetic-v3.8.0.min.js"></script>
<script src="jquery-1.7.1.js"></script>

Kinetic.js- 加载图像并使 em 可拖动
<script>
function drawImage(imageObj){
var stage = new Kinetic.Stage("container", 578, 500);
var layer = new Kinetic.Layer();
var x = stage.width / 2 - 200 / 2;
var y = stage.height / 2 - 137 / 2;
var width = 200;
var height = 137;
// darth vader
var darthVaderImg = new Kinetic.Shape(function(){
var context = this.getContext();
context.drawImage(imageObj, x, y, width, height);
// draw invisible detectable path for image
需要有关此 jquery 函数的帮助,如何使用它并在此处传递动力学 js 可拖动图像
$(function() {
$(this).draggable({ grid: [ 80, 80 ] });
});
context.beginPath();
context.rect(x, y, width, height);
context.closePath();
});
可拖动功能
// enable drag and drop
darthVaderImg.draggable(true);
// add cursor styling
darthVaderImg.on("mouseover", function(){
document.body.style.cursor = "pointer";
});
darthVaderImg.on("mouseout", function(){
document.body.style.cursor = "default";
});
//remove image on double click
darthVaderImg.on("dblclick dbltap", function(){
layer.remove(darthVaderImg);
layer.draw();
});
layer.add(darthVaderImg);
stage.add(layer);
//events
}
function drawImage2(imageObj){
var stage = new Kinetic.Stage("container", 578, 500);
var layer = new Kinetic.Layer();
var x = stage.width / 2 - 300 ;
var y = stage.height / 2 - 137 ;
var width = 200;
var height = 137;
// darth vader
var darthVaderImg2 = new Kinetic.Shape(function(){
var context = this.getContext();
context.drawImage(imageObj, x, y, width, height);
// draw invisible detectable path for image
context.beginPath();
context.rect(x, y, width, height);
context.closePath();
});
// enable drag and drop
darthVaderImg2.draggable(true);
// add cursor styling
darthVaderImg2.on("mouseover", function(){
document.body.style.cursor = "pointer";
});
darthVaderImg2.on("mouseout", function(){
document.body.style.cursor = "default";
});
//remove image on double click
darthVaderImg2.on("dblclick dbltap", function(){
layer.remove(darthVaderImg2);
layer.draw();
});
layer.add(darthVaderImg2);
stage.add(layer);
}
function load(img){
// load image
var imageObj = new Image();
imageObj.onload = function(){
drawImage(this);
};
imageObj.src = img.src;
};
function load2(img){
// load image
var imageObj = new Image();
imageObj.onload = function(){
drawImage2(this);
};
imageObj.src = img.src;
};
</script>
html定义图片点击操作
<title>HTMl5 drag drop multiple elements</title></head>
<body onmousedown="return false;">
<div id="container">
</div>
<div id="check1">
<ul id="img" class="draggable ui-widget-content" > <li><a href="#" class="draggable ui-widget-content" onclick="load(document.getElementById('i1'))">

<li>
<a href="#" onclick="load(document.getElementById('i2'))">

</ul>
</div>
