如何在JavaScript中打印所有百分比超过70％的学生姓名？
您可以使用for循环，并使用if条件检查百分比是否大于70。
以下是每个学生的记录-
const studentDetails=
[
{
studentName:"John",
percentage:78
},
{
studentName:"Sam",
percentage:68
},
{
studentName:"Mike",
percentage:88
},
{
studentName:"Bob",
percentage:70
}
]现在，对百分比大于70的学生使用for循环和et条件-
for(var index=0;index<studentDetails.length;index++)
{
if(studentDetails[index].percentage > 70)
{
//
}
}示例
const studentDetails=
[
{
studentName:"John",
percentage:78
},
{
studentName:"Sam",
percentage:68
},
{
studentName:"Mike",
percentage:88
},
{
studentName:"Bob",
percentage:70
}
]
for(var index=0;index<studentDetails.length;index++){
if(studentDetails[index].percentage > 70){
console.log("Student Name which has more than 70
%="+studentDetails[index].studentName);
}
}要运行以上程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo68.js。这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo68.js Student Name which has more than 70 %=John Student Name which has more than 70 %=Mike
