SVG可以使用JQuery和Jquery-svg拖动

sky*_*oot 33 jquery svg jquery-ui

我有一个HTML 5页面,我加载一个svg圈.当我点击圆圈时,我会创建另一个小圆圈,然后单击.我希望能够拖动第二个圆圈,但似乎无法使用jquery-ui .draggable();

我可以通过访问它的cx和cy属性来移动圆圈,因此必须有一种方法来拖动它.

jQuery UI可拖动行为确实有效,但您需要在拖动处理程序中手动更新位置,因为相对CSS定位在SVG内部不起作用.

svg.rect(20,10,100,50, 10, 10, {fill:'#666'});
svg.rect(40,20,100,50, 10, 10, {fill:'#999'});
svg.rect(60,30,100,50, 10, 10, {fill:'#ccc'});

$('rect')
  .draggable()
  .bind('mousedown', function(event, ui){
    // bring target to front
    $(event.target.parentElement).append( event.target );
  })
  .bind('drag', function(event, ui){
    // update coordinates manually, since top/left style props don't work on SVG
    event.target.setAttribute('x', ui.position.left);
    event.target.setAttribute('y', ui.position.top);
  });
