javascript - clsid :D27CDB6E-AE6D-11cf-96B8-444553540000 的相关性是什么

Question

来自 jQuery 1.7rc1 来源:

noData: {
    "embed": true,
    // Ban all objects except for Flash (which handle expandos)
    "object": "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000",
    "applet": true
},

什么是 clsid:D27CDB6E-AE6D-11cf-96B8-444553540000？

Answer 1

只要对象不是 Shockwave flash对象，设置 expando 属性将不起作用 ( "expando property" )，因为将抛出无法捕获的错误。一看源码，这个方法是interna

来源:

// The following elements throw uncatchable exceptions if you
// attempt to add expando properties to them.
noData: {
    "embed": true,
    // Ban all objects except for Flash (which handle expandos)
    "object": "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000",
    "applet": true
},

搜索 the source对于 noData，出现了许多带有适当注释的引用。
