Javascript kullanarak tablo oluşturun

Question 1

3 satır 2 hücre içeren bir tablo oluşturan bir JavaScript işlevim var.

Herhangi biri bana fonksiyonumu kullanarak aşağıdaki tabloyu nasıl oluşturabileceğimi söyleyebilir mi (bunu durumum için yapmam gerekiyor)?

İşte benim javascript ve html kodum aşağıda verilmiştir:

function tableCreate() {
  //body reference 
  var body = document.getElementsByTagName("body")[0];

  // create elements <table> and a <tbody>
  var tbl = document.createElement("table");
  var tblBody = document.createElement("tbody");

  // cells creation
  for (var j = 0; j <= 2; j++) {
    // table row creation
    var row = document.createElement("tr");

    for (var i = 0; i < 2; i++) {
      // create element <td> and text node 
      //Make text node the contents of <td> element
      // put <td> at end of the table row
      var cell = document.createElement("td");
      var cellText = document.createTextNode("cell is row " + j + ", column " + i);

      cell.appendChild(cellText);
      row.appendChild(cell);
    }

    //row added to end of table body
    tblBody.appendChild(row);
  }

  // append the <tbody> inside the <table>
  tbl.appendChild(tblBody);
  // put <table> in the <body>
  body.appendChild(tbl);
  // tbl border attribute to 
  tbl.setAttribute("border", "2");
}

<table width="100%" border="1">
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td rowspan="2">&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
  </tr>
</table>

Question 2

Bu çalışmalıdır (yukarıdaki kodunuzda birkaç değişiklikten).

function tableCreate() {
  var body = document.getElementsByTagName('body')[0];
  var tbl = document.createElement('table');
  tbl.style.width = '100%';
  tbl.setAttribute('border', '1');
  var tbdy = document.createElement('tbody');
  for (var i = 0; i < 3; i++) {
    var tr = document.createElement('tr');
    for (var j = 0; j < 2; j++) {
      if (i == 2 && j == 1) {
        break
      } else {
        var td = document.createElement('td');
        td.appendChild(document.createTextNode('\u0020'))
        i == 1 && j == 1 ? td.setAttribute('rowSpan', '2') : null;
        tr.appendChild(td)
      }
    }
    tbdy.appendChild(tr);
  }
  tbl.appendChild(tbdy);
  body.appendChild(tbl)
}
tableCreate();

Question 3

Biraz daha kısa kod kullanarak insertRowve insertCell:

function tableCreate(){
    var body = document.body,
        tbl  = document.createElement('table');
    tbl.style.width  = '100px';
    tbl.style.border = '1px solid black';

    for(var i = 0; i < 3; i++){
        var tr = tbl.insertRow();
        for(var j = 0; j < 2; j++){
            if(i == 2 && j == 1){
                break;
            } else {
                var td = tr.insertCell();
                td.appendChild(document.createTextNode('Cell'));
                td.style.border = '1px solid black';
                if(i == 1 && j == 1){
                    td.setAttribute('rowSpan', '2');
                }
            }
        }
    }
    body.appendChild(tbl);
}
tableCreate();

Ayrıca, bu tür bir ayarlama gibi bazı "kötü uygulamalar", kullanmaz borderniteliğini yerine CSS kullanarak ve erişir bodyaracılığıyla document.bodyyerine document.getElementsByTagName('body')[0];

Question 4

function addTable() {
  var myTableDiv = document.getElementById("myDynamicTable");

  var table = document.createElement('TABLE');
  table.border = '1';

  var tableBody = document.createElement('TBODY');
  table.appendChild(tableBody);

  for (var i = 0; i < 3; i++) {
    var tr = document.createElement('TR');
    tableBody.appendChild(tr);

    for (var j = 0; j < 4; j++) {
      var td = document.createElement('TD');
      td.width = '75';
      td.appendChild(document.createTextNode("Cell " + i + "," + j));
      tr.appendChild(td);
    }
  }
  myTableDiv.appendChild(table);
}
addTable();

<div id="myDynamicTable"></div>

Question 7

Umarım bunu faydalı bulursunuz.

HTML:

<html>
<head>
    <link rel = "stylesheet" href = "test.css">
<body>

</body>
<script src = "test.js"></script>
</head>
</html>

JAVASCRIPT:

var tableString = "<table>",
    body = document.getElementsByTagName('body')[0],
    div = document.createElement('div');

for (row = 1; row < 101; row += 1) {

    tableString += "<tr>";

    for (col = 1; col < 11; col += 1) {

        tableString += "<td>" + "row [" + row + "]" + "col [" + col + "]" + "</td>";
    }
    tableString += "</tr>";
}

tableString += "</table>";
div.innerHTML = tableString;
body.appendChild(div);

Question 8

Bu özel soruda açıklanan sorunu çözmeyebilir, ancak nesneler dizisinden tablolar oluşturmak isteyen kişiler için yararlı olabilir:

function createTable(objectArray, fields, fieldTitles) {
  let body = document.getElementsByTagName('body')[0];
  let tbl = document.createElement('table');
  let thead = document.createElement('thead');
  let thr = document.createElement('tr');
  fieldTitles.forEach((fieldTitle) => {
    let th = document.createElement('th');
    th.appendChild(document.createTextNode(fieldTitle));
    thr.appendChild(th);
  });
  thead.appendChild(thr);
  tbl.appendChild(thead);

  let tbdy = document.createElement('tbody');
  let tr = document.createElement('tr');
  objectArray.forEach((object) => {
    let tr = document.createElement('tr');
    fields.forEach((field) => {
      var td = document.createElement('td');
      td.appendChild(document.createTextNode(object[field]));
      tr.appendChild(td);
    });
    tbdy.appendChild(tr);    
  });
  tbl.appendChild(tbdy);
  body.appendChild(tbl)
  return tbl;
}

createTable([
  {name: 'Banana', price: '3.04'},
  {name: 'Orange', price: '2.56'},
  {name: 'Apple', price: '1.45'}
],
['name', 'price'], ['Name', 'Price']);

Question 10

Tabloyu bir dizge olarak oluşturmak için bir nesne listesini dinamik olarak ayrıştırabilen bir sürüm yazdım. Başlık sütunlarını, gövde satırlarını yazmak ve hepsini bir araya getirmek için onu üç işleve ayırdım. Bir sunucuda kullanılmak üzere bir dize olarak dışa aktardım. Kodum , her şeyi zarif tutmak için şablon dizeleri kullanıyor .

Stil eklemek istiyorsanız (önyükleme gibi), bu HEAD_PREFIXve 'ye daha fazla html ekleyerek yapılabilir HEAD_SUFFIX.

// helper functions
const TABLE_PREFIX = '<div><table class="tg">';
const TABLE_SUFFIX = '</table></div>';
const TABLE_HEAD_PREFIX = '<thead><tr>';
const TABLE_HEAD_SUFFIX = '</tr></thead>';
const TABLE_BODY_PREFIX = '<tbody><tr>';
const TABLE_BODY_SUFFIX = '</tr></tbody>';

function generateTableHead(cols) {
  return `
    ${TABLE_HEAD_PREFIX}
      <td>#</td>
    ${cols.map((col) => `<td>${col}</td>`).join('')}
    ${TABLE_HEAD_SUFFIX}`;
}

function generateTableBody(cols, data) {
  return `
    ${TABLE_BODY_PREFIX}
    ${data.map((object, index) => `
        <tr><td>${index}</td>
        ${cols.map((col) => `<td>${object[col]}</td>`).join('')}
      </tr>`).join('')}
    ${TABLE_BODY_SUFFIX}`;
}

/**
 * generate an html table from an array of objects with the same values
 *
 * @param {array<string>} cols array of object columns used in order of columns on table
 * @param {array<object>} data array of objects containing data in a single depth
 */
function generateTable(data, defaultCols = false) {
  let cols = defaultCols;
  if (!cols) cols = Object.keys(data[0]); // auto generate columns if not defined
  return `
    ${TABLE_PREFIX}
    ${generateTableHead(cols)}
    ${generateTableBody(cols, data)}
    ${TABLE_SUFFIX}`;
}

İşte bir örnek kullanım:

const mountains = [
  { height: 200, name: "Mt. Mountain" },
  { height: 323, name: "Old Broken Top"},
]
const htmlTableString = generateTable(mountains );

Bu, bir javascript nesnesi boyunca nasıl döngü yapılacağı ve verileri bir tabloya koyma yöntemidir, kod @ Vanuan'ın cevabından değiştirilir.

                  {name: 'Apple', price: '1.45'}
               ])
