我有一個顯示「時間軸」的片段。 Line(SVG組)應根據鼠標移動向左或向右移動。控制檯顯示要使用的數據,但我不知道如何移動g#node-line
。將SVG組左右移動
這是粗糙的結構:
svg#svg
g#node-line
line#line
g#nodes
line.node
line.node
line.node
line.node
...
現在代碼:
var ns = "http://www.w3.org/2000/svg";
var svg = document.createElementNS(ns, "svg");
svg.setAttribute("id", "svg");
svg.setAttribute("width", "800px");
svg.setAttribute("height", "450px");
var line = document.createElementNS(ns, "line");
line.setAttribute("id", "line");
line.setAttribute("stroke", "white");
line.setAttribute("stroke-width", "10px");
line.setAttribute("x1", "0");
line.setAttribute("y1", 225);
line.setAttribute("x2", "800");
line.setAttribute("y2", 225);
var nodes = document.createElementNS(ns, "g");
nodes.setAttribute("id", "nodes");
for (var i = 0; i < 100; i++) {
var node = document.createElementNS(ns, "line");
node.setAttribute("class", "node");
node.setAttribute("stroke", "white");
node.setAttribute("stroke-width", "2px");
node.setAttribute("x1", i * 40);
node.setAttribute("y1", 225);
node.setAttribute("x2", i * 40);
node.setAttribute("y2", 225 - 12);
nodes.appendChild(node);
}
var nodeLine = document.createElementNS(ns, "g");
nodeLine.setAttribute("id", "node-line");
nodeLine.appendChild(line);
nodeLine.appendChild(nodes);
svg.appendChild(nodeLine);
var container = document.getElementById('container');
container.appendChild(svg);
document.getElementById('svg').addEventListener('mousemove', function(e) {
var boundaries = svg.getBoundingClientRect()
var offset = e.clientX - boundaries.left;
if (offset < 400) {
var distanceFromCenter = 400 - offset;
console.log('left: ' + distanceFromCenter);
}
if (offset > 400) {
var distanceFromCenter = offset - 400;
console.log('right: ' + distanceFromCenter);
}
});
html, body {
height: 100%;
}
body {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
overflow: hidden;
}
#container {
background-color: orange;
}
<div id="container"></div>
非常感謝你。
有沒有像translateX-attribute這樣的東西?!?! – Timo
是的。有用。但我該如何平滑運動!?!? – Timo
好吧我做到了......:D我正在使用從中心到鼠標位置的距離:'distanceFromCenter' ...:D謝謝! – Timo
