无法在jQuery插件中

Question

我使用了MIT / GPL许可的jQueryPlugin（用于缩放）并对其进行了修改以满足我的需求。 不幸的是，代码执行没有按预期停止。从理论上讲，当鼠标离开标记为缩放的图像时，它会立即停止。

在＆＃34; cursorPOS＆＃34;函数，检查鼠标是否在容器外：

if (posY < offset.top || posX < offset.left || posY > (offset.top + imageHeight) || posX > (offset.left + imageWidth)) {
    $(imagezoomCursor.selector).remove();
    $('#RadialBox > img[id!="TraversalZoomImage5x"]').remove();
    $('#RadialBox').removeClass('radialzoom-view').append('<img data-radialzoom="' + radialZoomSource + '" src="' + radialSource + '" class="radialzoom">');
    return;
}

它执行得非常好，但它不会停止执行，即使我发送了返回命令。有没有人有想法，如何解决这个问题？
