如何使用JavaScript打印對象數組
[英]How to print an object array with JavaScript
問題描述
我聲明了4個對象並將它們推送到數組myArray 。 現在我想使用JavaScript在表中打印這個數組。
這是我的代碼：
<style> #div1 { background:pink; width:100%; height:80%; padding:5%; border:1px solid black; } table,th,td { border:1px solid black; padding:1px; } </style>
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <style> #div1 { background:pink; width:100%; height:80%; padding:5%; border:1px solid black; } table,th,td { border:1px solid black; padding:1px; } </style> </head> <body> <div id="div1"> <table> <script> var student1 = { Name: "Amol", rno: 1, Class: "MCA", Div: "A" }; var student2 = { Name: "Sagar", rno: 2, Class: "MBA", Div: "B" }; var student3 = { Name: "Bhushan", rno: 1, Class: "MMM", Div: "C" }; var student4 = { Name: "Nachiket", rno: 1, Class: "MPM", Div: "A" }; var MyArray = []; myArray[0].push(student1); myArray[1].push(student2); myArray[2].push(student3); myArray[3].push(student4); //document.write("<tr><th>"+ Name+</th>"+ //"<th>RollNumber</th>" //"<th>Class</th>" //"<th>Division</th>"); //"</tr>" alert("p"); for (var i = 0; i < MyArray.length; i++) { document.write("<tr><td>" + MyArray[i].Name + "</td>"); document.write("<td>" + MyArray[i].rno + "</td>"); document.write("<td>" + MyArray[i].Class + "</td></tr>"); document.write("<td>" + MyArray[i].Div + "</td></tr></br>"); } </script> </table> </div> </body> </html>

您的代碼中幾乎沒有錯誤：
- 您可以互換使用
MyArray和myArray，因此請保持一致。 - 當您在數組中推送項目時，請不要使用索引。 正確的語法是：
myArray.push(student1);
所以你的代碼變成：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style>
#div1
{
background:pink;
width:100%;
height:80%;
padding:5%;
border:1px solid black;
}
table,th,td {
border:1px solid black;
padding:1px;
}
</style>
</head>
<body>
<div id="div1">
<table>
<script>
var student1 = { Name: "Amol", rno: 1, Class: "MCA", Div: "A" };
var student2 = { Name: "Sagar", rno: 2, Class: "MBA", Div: "B" };
var student3 = { Name: "Bhushan", rno: 1, Class: "MMM", Div: "C" };
var student4 = { Name: "Nachiket", rno: 1, Class: "MPM", Div: "A" };
var myArray = [];
myArray.push(student1);
myArray.push(student2);
myArray.push(student3);
myArray.push(student4);
//document.write("<tr><th>"+ Name+</th>"+
//"<th>RollNumber</th>"
//"<th>Class</th>"
//"<th>Division</th>");
//"</tr>"
alert("p");
for (var i = 0; i < myArray.length; i++) {
document.write("<tr><td>" + myArray[i].Name + "</td>");
document.write("<td>" + myArray[i].rno + "</td>");
document.write("<td>" + myArray[i].Class + "</td></tr>");
document.write("<td>" + myArray[i].Div + "</td></tr></br>");
}
</script>
</table>
</div>
</body>
</html>

你需要更新
myArray[0].push(student1);
myArray[1].push(student2);
myArray[2].push(student3);
myArray[3].push(student4);
至
myArray.push(student1);
myArray.push(student2);
myArray.push(student3);
myArray.push(student4);
