Preface Load Mask (Mask) effect, that is, before the page is fully displayed, add a transfer effect. For example: Adding such an effect has two advantages: 1. mask the following pages before they are fully displayed to prevent illegal operations. 2. If the page show takes a long time, it will temporarily attract the user's attention (that is, improveUser Experience). In Extjs, there are many ways to use Ext js. You may find out why load mask does not appear in some situations? Let's hear the fo

Javascript: ObjectObjects we have briefly introduced before. They are a type of object that aggregates multiple data values in one unit and uses names for access. They are a disordered set of attributes.1. Several ways to create objectsCopy codeThe Code is as follows:Var empty ={} // create an object without attributes.Var person = {name: "ben", age: 22, sex: 'male'} // create an object using a direct volumeVar people = {name: 'Frank ', age: 21}, {name: 'Mary', age: 21}, sex: 'Man '} // The obje

Exercise The map () function is used to change the nonstandard English names entered by the user into uppercase letters and other standard names in lower case. Input: ['Adam ', 'Lisa',

object before the sequential action (). This allows objects to be cleared before being serialized. Similarly, when unserialize () is used to restore an object, the _ wakeup () member function is called.

is no need to use reduce. However, to convert the sequence [1, 3, 5, 7, 9] to an integer of 13579, reduce can be used in the following ways: >>> def fn(x, y):... return x * 10 + y...>>> reduce(fn, [1, 3, 5, 7, 9])13579 This example is of little use. However, if the string 'str' is also a sequence, we can write a function that converts 'str' to 'int' with map: >>> def fn(x, y):... return x * 10 + y...>>> def char2num(s):... return {'0': 0, '1': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6,

Map () is a Python built-in high-order function that receives a function f and a list, and then, by putting the function f on each element of the list in turn, gets a new list and returns.For example, for list [1, 2, 3, 4, 5, 6, 7, 8, 9]If you want to square each element of the list, you can use the map () function:Therefore, we only need to pass in the function f (x) =x*x, we can use the map () function to complete this calculation:def f (x): return X*xprint map (f, [1, 2, 3, 4, 5, 6, 7, 8,
