我想使用Xvfb无头测试WebGL代码.有谁知道怎么做？
我有2台机器 - 都运行Ubuntu.一个使用NVidia卡,另一个使用ATI:
NVidia机器:
ipmi:~ $>xvfb-run glxinfo
name of display: :455
display: :455 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:
GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating,
GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, GLX_OML_swap_method,
GLX_SGI_make_current_read, GLX_SGIS_multisample, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_MESA_copy_sub_buffer, GLX_INTEL_swap_event
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
...
ipmi:~ $>xvfb-run glxgears
3725 frames in 5.0 seconds = 741.884 FPS
3840 frames in …我目前使用以下语法来定义具有getter和setter的类.
SomeObject = function() {
this._propertyOne = 'test';
}
SomeObject.prototype.__defineGetter__('propertyOne', function() {
return this._propertyOne;
});
SomeObject.prototype.__defineSetter__('propertyOne', function(value) {
this._propertyOne = value;
});
然后我可以像这样访问该属性:
var o = new SomeObject();
o.propertyOne = 'test2';
console.log(o.propertyOne);
如何使用非弃用的defineProperty命令或类似的东西实现相同的功能？
我试过这样的事情:
Object.defineProperty(SomeObject.prototype, 'propertyOne', {
get: function() {
return this._propertyOne;
}.bind(this),
set: function(value) {
this._propertyOne = value;
}.bind(this)
});
但它不起作用.
