Lodash是一個JavaScript庫,可在underscore.js之上運行。 Lodash幫助處理數組,字符串,對象,數字等。
_.neq()方法使用鬆散不等式(!=)並相應地返回布爾值,以檢查每個參數是否不等於前一個參數。
用法:
_.neq( val1, val2, ..., valn )
參數:此方法采用可變數量的值對其進行運算。
返回值:此方法返回一個布爾值。
注意:由於它需要安裝lodash contrib庫,因此在正常的JavaScript中將無法使用。可以使用npm install lodash-contrib -save安裝Lodash contrib庫。
範例1:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Using the _.neq() method
var neq = _.neq( 3, 1 );
console.log(
"Each arguments are not equal " +
"to previous one:", neq
);
輸出:
Each arguments are not equal to previous one:true
範例2:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Using the _.neq() method
var neq = _.neq( 8, 8 );
console.log(
"Each arguments are not equal " +
"to previous one:", neq
);
輸出:
Each arguments are not equal to previous one:false
範例3:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Using the _.neq() method
var neq = _.neq( 8, 6, 4, 12 );
console.log(
"Each arguments are not equal " +
"to previous one:", neq
);
輸出:
Each arguments are not equal to previous one:true
範例4:
Javascript
// Defining lodash contrib variable
var _ = require('lodash-contrib');
// Using the _.neq() method
var neq = _.neq( 8, 8, 8, 8 );
console.log(
"Each arguments are not equal " +
"to previous one:", neq
);
輸出:
Each arguments are not equal to previous one:false
