在遍历节点的方法中,$(selector).each(function(index, element)); 语法中的element代表______。
举一反三
- 下面关于遍历节点说法真确的是 A: jQuery提供的each()方法遍历所有元素,并进行相关的处理。 B: 语法结构是$(selector).each(function(index, element)); C: each()方法的参数是一个匿名函数 D: index是遍历元素的索引,索引默认从1开始
- If A is a matrix, the function of the function max(a(:)) is ( ). A: to work out the maximum element of the entire matrix B: function call errors C: to work out the maximum element of each row of the matrix D: to work out the maximum element of each column of the matrix
- If A is a matrix, the function max(A(:)) is ( ). A: to return the first element B: to return the maximum element in each row of the matrix C: to return the maximum element in each column of the matrix D: to return the largest element of the entire matrix
- jQuery中遍历指定的对象和数组是哪个方法() A: $.each(object,callback) B: $(selector).each(function()) C: foreach() D: for...in
- 下面不属于List接口方法的是 A: void add(int index,Object element) B: Object set(int index,Object element) C: Object get(int index) D: Vector(int size)
