Underscore.js _.sneq() 方法
_.sneq()方法 c 检查每个参数是否严格不相等 ( === ) 。因此,相应地返回一个布尔值。
句法:
_.sneq( val1, val2, ..., valn );
参数:此方法需要 n 个值对其进行操作。
返回值:此方法返回一个布尔值。
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 eq = _.sneq( 1, 2, 3 );
console.log("Each arguments are not "
+ "equal to each other :", eq);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.sneq( 2, 2, 2 );
console.log("Each arguments are not "
+ "equal to each other :", eq);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.sneq( "2", 2, 2 );
console.log("Each arguments are not "
+ "equal to each other :", eq);
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.sneq( "2", "2", "2" );
console.log("Each arguments are not "
+ "equal to each other :", eq);
输出:
Each arguments are not equal to each other : true
示例 2:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.sneq( 2, 2, 2 );
console.log("Each arguments are not "
+ "equal to each other :", eq);
输出:
Each arguments are not equal to each other : false

示例 4:
Javascript
// Defining underscore contrib variable
var _ = require('underscore-contrib');
var eq = _.sneq( "2", "2", "2" );
console.log("Each arguments are not "
+ "equal to each other :", eq);
输出:
Each arguments are not equal to each other : false
