几年前,我被要求使用 SVG 创建一个基于 Ajax 的 2 人游戏。它可能不是您正在寻找的解决方案,但它可以帮助您侦听 SVG 中的事件。这是 SVG 控制器:
仅供参考,SVG正在被拖放(它是Stratego)
/****************** Track and handle SVG object movement *************/
var svgDoc;
var svgRoot;
var mover=''; //keeps track of what I'm dragging
///start function////
//do this onload
function start(evt){
//set up the svg document elements
svgDoc=evt.target.ownerDocument;
svgRoot=svgDoc.documentElement;
//add the mousemove event to the whole thing
svgRoot.addEventListener('mousemove',go,false);
//do this when the mouse is released
svgRoot.addEventListener('mouseup',releaseMouse,false);
}
// set the id of the target to drag
function setMove(id){ mover=id; }
// clear the id of the dragging object
function releaseMouse(){
if(allowMoves == true){ sendMove(mover); }
mover='';
}
// this is launched every mousemove on the doc
// if we are dragging something, move it
function go(evt){
if(mover != '' && allowMoves != false) {
//init it
var me=document.getElementById(mover);
//actually change the location
moveX = evt.clientX-135; //css positioning minus 1/2 the width of the piece
moveY = evt.clientY-65;
me.setAttributeNS(null, 'x', evt.clientX-135);
me.setAttributeNS(null, 'y', evt.clientY-65);
}
}
function moveThis(pieceID, x, y) {
$(pieceID).setAttributeNS(null, 'x', x);
$(pieceID).setAttributeNS(null, 'y', y);
}
我的应用程序是纯 SVG + JavaScript,但这就是它的要点。
