// First batch of tests.

opt = select.appendChild( document.createElement("option") );

// Test setAttribute on camelCase class. If it works, we need attrFixes when doing get/setAttribute (ie6/7)

检测input是否支持getAttribute("value")
复制代码 代码如下:
// Support: IE8 only
// Check if we can trust getAttribute("value")
input = document.createElement( "input" );
input.setAttribute( "value", "" );
support.input = input.getAttribute( "value" ) === "";
检测是否布尔值属性
复制代码 代码如下:
booleans = "checked|selected|async|autofocus|autoplay|controls|defer|disabled|hidden|ismap|loop|multiple|open|readonly|required|scoped",
matchExpr = {
"bool": new RegExp( "^(?:" + booleans + ")$", "i" )
},
