以下有关属性选择器说法正确的是()。
A: E[foo^="bar"]:匹配foo属性值以“bar”结束的E元素。
B: E[foo^="bar"]:匹配foo属性值以“bar”开始的E元素。
C: E[foo$="bar"]:匹配foo属性包含“bar”的E元素。
D: E[foo*="bar"]:匹配foo属性值以“bar”结束的E元素。
A: E[foo^="bar"]:匹配foo属性值以“bar”结束的E元素。
B: E[foo^="bar"]:匹配foo属性值以“bar”开始的E元素。
C: E[foo$="bar"]:匹配foo属性包含“bar”的E元素。
D: E[foo*="bar"]:匹配foo属性值以“bar”结束的E元素。
举一反三
- Which code, inserted at line 15, allows the class Sprite to compile?() A: Foo{public int bar(){return 1;}} B: new Foo{public int bar(){return 1;}} C: new Foo(){public int bar(){return 1;}} D: new class Foo{public int bar(){return 1;}}
- var bar=123 function foo () { console.log(bar) var bar=456 console.log(bar); } console.log(bar) foo() 请问输出的结果依次为 A: 123,456,123 B: undefined,456,123 C: 123,undefined,456 D: 123,123,456
- Which of the following are NOT valid if/else statements in Python, assuming x and y are defined appropriately: A: if x < y: print('foo') else: print('bar') B: if x < y and x > 10: print('foo') C: if x < y: print('foo'); print('bar'); print('baz') D: if x < y: print('foo') elif y < x: print('bar') else: print('baz')
- 在Java script中,运行下面代码的结果是 function foo(x){ var num=5; bar=function(y){ return (x+y+(++num)); } } console.log(foo(2)); console.log(bar(10)); console.log(bar(10));"
- int index = 1; int foo = new int ; int bar = foo [index]; int baz = bar + index; What is the result?() A: Baz has the value of 0 B: Baz has the value of 1 C: Baz has the value of 2 D: An exception is thrown. E: The code will not compile.
