So in your case, the if/else equivalent to your conditional operator would be: if (el.style.visibility == "visible") { el.style.visibility = "hidden"; } else { el.style.visibility = "visible"; } Likewise, nesting two conditional operators can yield an equivalent expression to your if...
monthName= "January"; }elseif(userInput == 2) { monthName= "February"; }elseif(userInput == 3) { monthName= "March"; }else{ monthName= "Unknown month number"} alert(monthName); ternary operator基于多个条件的例子:在以下的例子中,if-else-if语句会被ternary operator所取代 varuserInput = N...
ESLint 规则no-nested-ternary当检测到代码中存在嵌套的三元表达式时,会发出警告或错误。该规则旨在通过禁止使用嵌套的三元表达式来提升代码的可读性和可维护性,因为随着条件复杂度的增加,深度嵌套的三元表达式往往会变得难以理解和推理。 三元表达式:三元表达式是 JavaScript 中一种简化的 if-else 结构,包含三个部分: ...
I am just starting to use the JavaScript ternary operator to replace simple if/else statements. I have done so successfully in several places. I was surprised when I successfully made something else work when I thought for sure it wouldn't, but I tried anyway. Here's the original statement...
In JavaScript, if..else is the most basic conditional statement, it consists of three parts:condition, statement1, statement2, like this: if (condition) statementa else statementb i...
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...
JavaScript Code: constternary_Search=(arr,target,left,right)=>{if(right>=left){letmid1=Math.floor(left+(right-left)/3);letmid2=Math.floor(right-(right-left)/3);if(arr[mid1]==target){returnmid1;}elseif(arr[mid2]==target){returnmid2;}if(target<arr[mid1]){returnternary_Search(ar...
