javascript - 如何將文本框添加到2d數組

-3

如何添加文本框作爲2d數組的輸入？我有文本框作爲表單。將每個學生的輸入分配給座位的最簡單方法是什麼？編輯：我需要把document.getElementById（seat1）.innerhtml放入函數中嗎？javascript - 如何將文本框添加到2d數組

<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] 
}

<label for="Seat1">Seat 1 </label> 

<p id="seat1"></p>

你想在電腦自動安排座位和學生，或者你想給學生選擇席位他們自己，他們想要保留？ –

我希望它能像座老師一樣制定座位計劃，並且能夠爲每個學生設置座位，而且我將需要在這個東西中放置一些東西，我遺漏了 –

嘗試使用document.querySelectorAll（「input [type = text]」）來獲取所有類型爲「text」的輸入的數組。你需要遍歷它們。

/* 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)

<form id="studentForm"> 
 
<input type="text" name="student1" id="myInput1" value="Jon Doe1"> 
 
<input type="text" name="student2" id="myInput2" value="Jon Doe2"> 
 
<input type="text" name="student3" id="myInput3" value="Jon Doe3"><br> 
 
<input type="text" name="student4" id="myInput4" value="Jon Doe4"> 
 
<input type="text" name="student5" id="myInput5" value="Jon Doe5"> 
 
<input type="text" name="student6" id="myInput6" value="Jon Doe6"><br> 
 
<input type="text" name="student7" id="myInput7" value="Jon Doe7"> 
 
<input type="text" name="student8" id="myInput8" value="Jon Doe8"> 
 
<input type="text" name="student9" id="myInput9" value="Jon Doe9"><br> 
 
</form>

因此，var代碼將在函數內部要麼？ –

這是我到目前爲止http://pastebin.com/RVSJarc8 –

我修改了腳本，將學生添加到一個座位，24行和10列 –

這是我最後還是沒
