Example: JavaScript Ternary Conditional Operator Example: JavaScript Nested Ternary Operators Example: Multiple Operations in the JavaScript Ternary Operator This tutorial will introduce how to use the ?: conditional operator in JavaScript. ADVERTISEMENT The if ... else statement helps us execute a ...
The conditional operator is also known as the ternary operator. The JavaScript conditional (ternary) operator is only operator that takes three operands a condition followed by a question mark (?), then the first expression to be executed if the condition is truthy followed by a colon (:), ...
The ternary operator evaluates the test condition. If the condition istrue,expression1is executed. If the condition isfalse,expression2is executed. The ternary operator takesthreeoperands, hence, the name ternary operator. It is also known as a conditional operator. Let's write a program to dete...
条件(三元)运算符是JavaScript 唯一使用三个操作数的运算符:一个条件后跟一个问号(?),如果条件为真值,则执行冒号(:)前的表达式;若条件为假值,则执行最后的表达式。该运算符经常当作 if...else 语句的简捷形式来使用。 尝试一下语法 jsCopy to Clipboard condition ? exprIfTrue : exprIfFalse 参数 condition...
Chaining Ternary Operators In JavaScript, the ternary operator also allows conditional chains where the right-side condition chains into another ternary operator. By chaining ternary operators, you effectively write an “if ...else if ... else” conditional chain. But, of course, you have to be...
条件运算符(conditional operator)有时候也称为三元运算符(ternary operator,或者trinary operator),因为它是唯一需要 3 个操作数的运算符: var 属性名称=条件 ? 表达式1 : 表达式2; <!DOCTYPE html> 条件运算符 window.onload = function() { var testvalue1 = (12 > 3) ? "大于" : "小于"; var...
Learn the basics of the JavaScript Ternary OperatorThe ternary operator is the only operator in JavaScript that works with 3 operands, and it’s a short way to express conditionals.This is how it looks:<condition> ? <expression> : <expression>...
由操作数个数,运算符分一元Unary、二元Binary和三元Ternary。【在JS中只有条件运算符是三元运算符】 表达式Expression:可为直接量、变量、常量、也可以是(运算符、操作符和标点符号)组成的语句。 【直接量:值(如:1233、“abc”、true、[1,2,5]、{width:100,height:200} ….)】最后1个为对象直接量 ...
Lua has an exponentiation operator (^); JS doesn't. JS has many more operators, including the ternary conditional operator (?:), increment/decrement, bitwise operators, type operators (typeof and instanceof), additional assignment operators and additional comparison operators. ...
