Underscore.js _.lte() 方法

这 _。 lte()方法检查每个参数是否小于或等于其下一个参数。

句法:

_.lte( 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:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
  
var lesser  = _.lte(1, 4, 4);
  
console.log("Each argument is lesser than or equal to its next argument :", lesser);

输出:

Each argument is lesser than or equal to its next argument : true

示例 2:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
  
var lesser  = _.lte(1, 4, 9, 4);
  
console.log("Each argument is lesser than or equal to its next argument :", lesser);

输出:

Each argument is lesser than or equal to its next argument : true

示例 3:

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
  
var lesser  = _.lte(1, 4, 9, 4);
  
console.log("Each argument is lesser than or equal to its next argument :", lesser);

输出:

Each argument is lesser than or equal to its next argument : false
