angular2 表格点击选中与鼠标悬浮

注释

根据点击或悬浮事件得到选中行号，根据行号用[ngClass]绑定样式，若点击样式和悬浮样式同时起作用，把flag2=-1,去掉悬浮样式。

下面是unity自带的,在Scripts资源包里有拖拽代码，这个拖拽物体必须附加Rigidbody刚体组件。

DragRigidbodyjs

var spring = 500;

var damper = 50;

var drag = 100;

var angularDrag = 50;

var distance = 02;

var attachToCenterOfMass = false;

private var springJoint : SpringJoint;

function Update ()

{

// Make sure the user pressed the mouse down

if (!InputGetMouseButtonDown (0))

return;

var mainCamera = FindCamera();

// We need to actually hit an object

var hit : RaycastHit;

if (!PhysicsRaycast(mainCameraScreenPointToRay(InputmousePosition), hit, 100))

return;

// We need to hit a rigidbody that is not kinematic

if (!hitrigidbody || hitrigidbodyisKinematic)

return;

if (!springJoint)

{

var go = new GameObject("Rigidbody dragger");

var body : Rigidbody = goAddComponent ("Rigidbody") as Rigidbody;

springJoint = goAddComponent ("SpringJoint");

bodyisKinematic = true;

}

springJointtransformposition = hitpoint;

if (attachToCenterOfMass)

{

var anchor = transformTransformDirection(hitrigidbodycenterOfMass) + hitrigidbodytransformposition;

编程回忆录已经有八年的历史，是教程团队旗下的一个在线网络培训机构，目前已录制十三个科目，涉及到互联网开发，软件开发，游戏开发（虚拟现实开发）,现在编程回忆录的Unity3D是国内唯一一家中文连载的大型视频教程。零基础开始讲解，通俗易懂 ,以实战为目地，受到众多网友的一致好评。

展示方式不同，所用技术不同。前端开发用到的技术包括但不限于html。css。javascript、jquery、Bootstrap、Nodejs、AngularJs等技术。后端开发以java为例主要用到的是包括但不限于StrutsspringspringmvcHibernate>
