Underscore.js _.bitwiseZ() 方法
这 _。 bitwiseZ () 方法 r返回对所有参数使用按位 >>>运算符的结果。
句法:
_.bitwiseZ( val1, val2,..., valn );
参数:此方法需要 n 个值对其进行操作。
返回值:此方法返回对所有参数使用按位 >>>运算符的结果。
注意:这在普通 JavaScript 中不起作用,因为它需要安装 underscore.js contrib 库。
underscore.js contrib 库可以使用npm install underscore-contrib –save 安装。
示例 1:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 1 );
console.log("The bitwiseZ is :",bZ);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 1, 3 );
console.log("The bitwiseZ is :",bZ);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 72, 32 );
console.log("The bitwiseZ is :",bZ);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 72, 32, 2 );
console.log("The bitwiseZ is :",bZ);
输出:
The bitwiseZ is : 1
示例 2:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 1, 3 );
console.log("The bitwiseZ is :",bZ);
输出:
The bitwiseZ is : 0
示例 3:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 72, 32 );
console.log("The bitwiseZ is :",bZ);
输出:
The bitwiseZ is : 72
示例 4:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var bZ = _.bitwiseZ( 72, 32, 2 );
console.log("The bitwiseZ is :",bZ);
输出:
The bitwiseZ is : 18
