Example: "div > button.btn", if you use this string to tokenize,
Sizzle.tokenize returns an array with arrays as item and within that
array item there is an object that has property type and value. In
example above the results will be [[{type: "tag",value: "div"},{type:
">",value: " > "},{type: "tag",value: "button"},{type: "class",value:
"btn"}]].
如果您使用另一个带逗号的选择器，它会在父数组中添加新数组。
