祖先(FN,testSelf,stopFn)節點

返回經過供給布爾方法施加的測試的最近的祖先。 參數:

fn String | Function 

A selector string or boolean method for testing elements. If a function is used, it receives the current node being tested as the only argument. 
testSelf Boolean 

optional Whether or not to include the element in the scan 
stopFn String | Function 

optional A selector string or boolean method to indicate when the search should stop. The search bails when the function returns true or the selector matches. If a function is used, it receives the current node being tested as the only argument. 

返回: 節點:一致節點實例或空,如果沒有找到

+1

值得一提的是,YUI的'ancestor'不,本身相當於jQuery的'closest'。默認情況下'最接近'考慮當前元素/節點,而'ancestor'需要'true'作爲第二個參數傳遞以包含當前元素。 – nagytech
