動態表格中的可編輯單元格

Question

我正在嘗試使用變量no的動態表格。行和列。表格被創建，但是當我點擊單元格時，它們不可編輯，因爲我認爲它們會是。

$(document).ready(function() { 
 
      $("#createit").click(function() { 
 
       var num_rows = document.getElementById('rows').value; 
 
       var num_cols = document.getElementById('cols').value; 
 
       var tbody = ''; 
 
       for (var i = 0; i < num_rows; i++) { 
 
        tbody += '<tr>'; 
 
        for (var j = 0; j < num_cols; j++) { 
 
         tbody += '<td tabindex=' + j + '>'; 
 
         tbody += 'Cell' + i + j; 
 
         tbody += '</td>' 
 
        } 
 
        tbody += '</tr>'; 
 
       } 
 
       //document.getElementById('wrapper').innerHTML = theader + tbody + tfooter; 
 
       $('.editableTable').append(tbody); 
 
      }); 
 
     }); 
 
     $(".editableTable td").dblclick(function() { 
 
      console.log('clicked'); 
 
      var OriginalContent = $(this).text(); 
 
      $(this).addClass("cellEditing"); 
 
      $(this).html("<select><option>1</option><option>2</option><option >3</option></select>"); 
 
      $(this).children().first().focus(); 
 
      $(this).bgColor = 'red'; 
 

 
      $(this).children().first().keypress(function(e) { 
 
       if (e.which == 13) { 
 
        var newContent = OriginalContent; 
 
        $(this).parent().text(OriginalContent); 
 
        $(this).parent().removeClass("cellEditing"); 
 
       } 
 
      }); 
 
      $(this).children().first().blur(function() { 
 
       $(this).parent().text(OriginalContent); 
 
       $(this).parent().removeClass("cellEditing"); 
 
      }); 
 
     }); 
 
     $(".editableTable td").bind('keydown', function(event) { 
 
      if (event.keyCode === 9 || event.keyCode === 13) { 
 
       var tabindex = $(this).attr('tabindex'); 
 
       tabindex++; //increment tabindex 
 
       $('[tabindex=' + tabindex + ']').focus().dblclick(); 
 
       return false; 
 
      } 
 
     });

.editableTable { 
 
      border: solid 0px; 
 
      width: 100%; 
 
      text-align: center 
 
     } 
 

 
     .editableTable td { 
 
      border: solid 0.5px; 
 
      border-color: lightblue; 
 
      min-width: 100px; 
 
     } 
 

 
     .editableTable .cellEditing { 
 
      padding: 0; 
 
     } 
 

 
     select { 
 
      border: 0px; 
 
      width: 100%; 
 
     }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<label>Rows: <input type="text" name="rows" id="rows"/></label><br /> 
 
    <label>Cols: <input type="text" name="cols" id="cols"/></label><br/> 
 
    <input name="generate" type="button" value="Create Table!" id='createit' /> 
 
    <div id="wrapper"> 
 
     <table class="editableTable"> 
 
      <tbody></tbody> 
 
     </table> 
 
    </div>

同樣的事情，我以前而是一個靜態表來完成。 JSFIDDLE https://jsfiddle.net/rbrohitbisht/691rx62k/

現在我想用動態表做同樣的事情。我在這裏做錯了什麼？

Answer 1

該操作應該移入createit處理程序定義中。

$(".editableTable td").dblclick(function() {...}); 

剛創建好單元格後（當然在單擊克里特表格後！）。

否則，在動態表就位之前，選擇器$（「。editableTable td」）不會返回任何內容。

您應該添加contenteditable="true"到您的代碼

$(document).ready(function() { 
     $("#createit").click(function() { 
      var num_rows = document.getElementById('rows').value; 
      var num_cols = document.getElementById('cols').value; 
      var tbody = ''; 
      for (var i = 0; i < num_rows; i++) { 
       tbody += '<tr>'; 
       for (var j = 0; j < num_cols; j++) { 
        tbody += '<td contenteditable="true" tabindex=' + j + '>'; 
        tbody += 'Cell' + i + j; 
        tbody += '</td>' 
       } 
       tbody += '</tr>'; 
      } 
      //document.getElementById('wrapper').innerHTML = theader + tbody + tfooter; 
      $('.editableTable').append(tbody); 
     }); 
    }); 
    $(".editableTable td").dblclick(function() { 
     console.log('clicked'); 
     var OriginalContent = $(this).text(); 
     $(this).addClass("cellEditing"); 
     $(this).html("<select><option>1</option><option>2</option><option >3</option></select>"); 
     $(this).children().first().focus(); 
     $(this).bgColor = 'red'; 

     $(this).children().first().keypress(function(e) { 
      if (e.which == 13) { 
       var newContent = OriginalContent; 
       $(this).parent().text(OriginalContent); 
       $(this).parent().removeClass("cellEditing"); 
      } 
     }); 
     $(this).children().first().blur(function() { 
      $(this).parent().text(OriginalContent); 
      $(this).parent().removeClass("cellEditing"); 
     }); 
    }); 
    $(".editableTable td").bind('keydown', function(event) { 
     if (event.keyCode === 9 || event.keyCode === 13) { 
      var tabindex = $(this).attr('tabindex'); 
      tabindex++; //increment tabindex 
      $('[tabindex=' + tabindex + ']').focus().dblclick(); 
      return false; 
     } 
    }); 

Answer 3

use HTML DOM "contentEditable" Property Element Object https://stackoverflow.com/a/44380264/3615816

<input type=button value="Enable editing" 
 
onclick="document.getElementById('t1').contentEditable = 'true';alert('You can now edit table')" /> 
 

 
<table id="t1" border="1"> 
 
    
 
    <tr><td >c1</td><td >c2</td></tr> 
 
    <tr><td >cc1</td><td >cc2</td></tr> 
 

 
</table> 
 

 
<input type=button value="disable editing" 
 
onclick="document.getElementById('t1').contentEditable = 'false'; " />

$(document).ready(function() {
