如何添加文本框作为二维数组的输入？我将文本框作为表单。将每个学生输入分配到座位的最简单方法是什么？ 编辑：我需要将document.getElementById（seat1）.innerhtml放入函数吗？
<form id="studentForm">
<input type="text" name="student1" id="myInput1">
<input type="text" name="student2" id="myInput2">
<input type="text" name="student3" id="myInput3"><br>
<input type="text" name="student4" id="myInput4">
<input type="text" name="student5" id="myInput5">
<input type="text" name="student6" id="myInput6"><br>
<input type="text" name="student7" id="myInput7">
<input type="text" name="student8" id="myInput8">
<input type="text" name="student9" id="myInput9"><br>
</form>
<script type="text/javascript">
function myFunction() {
var seat = onearray(3)
seat[1] = onearray(3)
seat[1][1]
seat[1][2]
seat[1][3]
seat[2] = onearray(3)
seat[2][1]
seat[2][2]
seat[2][3]
seat[3] = onearray(3)
seat[3][1]
seat[3][2]
seat[3][3]
}
</script>
<label for="Seat1">Seat 1 </label>
<p id="seat1"></p>
<label for="Seat2">Seat 2 </label>
<p id="seat2"></p>
<label for="Seat3">Seat 3 </label>
<p id="seat3"></p>
<br>
<label for="Seat4">Seat 4 </label>
<p id="seat4"></p>
<label for="Seat5">Seat 5 </label>
<p id="seat5"></p>
<label for="Seat6">Seat 6 </label>
<p id="seat6"></p>
<br>
<label for="Seat7">Seat 7 </label>
<p id="seat7"></p>
<label for="Seat8">Seat 8 </label>
<p id="seat8"></p>
<label for="Seat9">Seat 9 </label>
<p id="seat9"></p>

尝试使用document.querySelectorAll（＆＃34; input [type = text]＆＃34;）来获取类型为＆＃34; text＆＃34;的所有输入的数组。你需要遍历它们。
Yes/* Select all the inputs wich have the type as a text, this will return an array */
var students = document.querySelectorAll("input[type=text]");
/* Create an empty multidimensional array, for the seats*/
var seats=[[],[]];
/* Initailize student counter to 0*/
var studentCounter=0;
/* Iterate the seats, most of the time the seats are character + number like: B-24 (file B seat 24), but this time in order to simplify the script I lef as a number like 2-24 (file 2 seat 24) */
// 24 files x 10 seats for each file = 240 available seats
for (var i =0; i <= 24; i++) {
for (var x=0; x < 10; x++) {
//Here we capture the input box content, example name of the student
if(students[studentCounter]){
seats[i][x]=students[studentCounter].value;
studentCounter++;
}
}
}
console.log(seats)

这就是我最后所做的
<html>
<head>
<title>Two Dimensional Arrays D</title>
<script type="text/javascript">
function Input()
{
var seat = new Array()
seat[0] = new Array();
seat[0][0] = Form1.txtInput1.value;
seat[0][1] = Form1.txtInput2.value;
seat[0][2] = Form1.txtInput3.value;
seat[1] = new Array();
seat[1][0] = Form1.txtInput4.value;
seat[1][1] = Form1.txtInput5.value;
seat[1][2] = Form1.txtInput6.value;
seat[2] = new Array();
seat[2][0] = Form1.txtInput7.value;
seat[2][1] = Form1.txtInput8.value;
seat[2][2] = Form1.txtInput9.value;
txtLabel1.value = seat[0][0]
txtLabel2.value = seat[0][1]
txtLabel3.value = seat[0][2]
txtLabel4.value = seat[1][0]
txtLabel5.value = seat[1][1]
txtLabel6.value = seat[1][2]
txtLabel7.value = seat[2][0]
txtLabel8.value = seat[2][1]
txtLabel9.value = seat[2][2]
}
