I'd like to make some cells of html table editable, simply double click a cell, input some text and the changes can be sent to server. I don't want to use some toolkits like dojo data grid. Because it provides some other features. Would you provide me some code snippet or advices on how to implement it?
You can use the contenteditable attribute on the cells, rows, or table in question.
Updated for IE8 compatibility
<table>
<tr><td><div contenteditable>I'm editable</div></td><td><div contenteditable>I'm also editable</div></td></tr>
<tr><td>I'm not editable</td></tr>
</table>
Just note that if you make the table editable, in Mozilla at least, you can delete rows, etc.
You'd also need to check whether your target audience's browsers supported this attribute.
As far as listening for the changes (so you can send to the server), see contenteditable change events
HTML5 supports contenteditable,
<table border="3">
<thead>
<tr>Heading 1</tr>
<tr>Heading 2</tr>
</thead>
<tbody>
<tr>
<td contenteditable='true'></td>
<td contenteditable='true'></td>
</tr>
<tr>
<td contenteditable='true'></td>
<td contenteditable='true'></td>
</tr>
</tbody>
</table>
3rd party edit
To quote the mdn entry on contenteditable
The attribute must take one of the following values:
true or the empty string, which indicates that the element must be editable;
false, which indicates that the element must not be editable.
If this attribute is not set, its default value is inherited from its parent element.
This attribute is an enumerated one and not a Boolean one. This means that the explicit usage of one of the values true, false or the empty string is mandatory and that a shorthand ... is not allowed.
// wrong not allowed
<label contenteditable>Example Label</label>
// correct usage
<label contenteditable="true">Example Label</label>.
I have three approaches,
Here you can use both <input> or <textarea> as per your requirements.
1. Use Input in <td>.
Using <input> element in all <td>s,
<tr><td><input type="text"></td>....</tr>
Also, you might want to resize the input to the size of its td. ex.,
input { width:100%; height:100%; }
You can additionally change the colour of the border of the input box when it is not being edited.
2. Use contenteditable='true' attribute. (HTML5)
However, if you want to use contenteditable='true', you might also want to save the appropriate values to the database. You can achieve this with ajax.
You can attach keyhandlers keyup, keydown, keypress etc to the <td>. Also, it is good to use some delay() with those events when user continuously types, the ajax event won't fire with every key user press. for example,
$('table td').keyup(function() {
clearTimeout($.data(this, 'timer'));
var wait = setTimeout(saveData, 500); // delay after user types
$(this).data('timer', wait);
});
function saveData() {
// ... ajax ...
}
3. Append <input> to <td> when it is clicked.
Add the input element in td when the <td> is clicked, replace its value according to the td's value. When the input is blurred, change the `td's value with the input's value. All this with javascript.
Try this code.
$(function () {
$("td").dblclick(function () {
var OriginalContent = $(this).text();
$(this).addClass("cellEditing");
$(this).html("<input type="text" value="" + OriginalContent + "" />");
$(this).children().first().focus();
$(this).children().first().keypress(function (e) {
if (e.which == 13) {
var newContent = $(this).val();
$(this).parent().text(newContent);
$(this).parent().removeClass("cellEditing");
}
});
$(this).children().first().blur(function(){
$(this).parent().text(OriginalContent);
$(this).parent().removeClass("cellEditing");
});
});
});

You can use x-editable https://vitalets.github.io/x-editable/ its awesome library from bootstrap
If you use Jquery, this plugin help you is simple, but is good
This is a single and runnable example.
<html>
<head>
<script src="http://cdn.bootcss.com/jquery/3.1.1/jquery.min.js"></script> <!-- jQuery source -->
</head>
<body>
<table align="center">
<tr> <td>id</td> <td>name</td> </tr>
<tr> <td>001</td> <td>dog</td> </tr>
<tr> <td>002</td> <td>cat</td> </tr>
<tr> <td>003</td> <td>pig</td> </tr>
</table>
<script>
$(function(){
$("td").click(function(event){
if($(this).children("input").length > 0)
return false;
var tdObj = $(this);
var preText = tdObj.html();
var inputObj = $("<input type='text' />");
tdObj.html("");
inputObj.width(tdObj.width())
.height(tdObj.height())
.css({border:"0px",fontSize:"17px"})
.val(preText)
.appendTo(tdObj)
.trigger("focus")
.trigger("select");
inputObj.keyup(function(event){
if(13 == event.which) { // press ENTER-key
var text = $(this).val();
tdObj.html(text);
}
else if(27 == event.which) { // press ESC-key
tdObj.html(preText);
}
});
inputObj.click(function(){
return false;
});
});
});
</script>
</body>
</html>
Just insert <input> element in <td> dynamically, on cell click. Only simple HTML and Javascript. No need for contentEditable , jquery, HTML5
this is actually so straight forward, this is my HTML, jQuery sample.. and it works like a charm, I build all the code using an online json data sample. cheers
<< HTML >>
<table id="myTable"></table>
<< jQuery >>
<script>
var url = 'http://jsonplaceholder.typicode.com/posts';
var currentEditedIndex = -1;
$(document).ready(function () {
$.getJSON(url,
function (json) {
var tr;
tr = $('<tr/>');
tr.append("<td>ID</td>");
tr.append("<td>userId</td>");
tr.append("<td>title</td>");
tr.append("<td>body</td>");
tr.append("<td>edit</td>");
$('#myTable').append(tr);
for (var i = 0; i < json.length; i++) {
tr = $('<tr/>');
tr.append("<td>" + json[i].id + "</td>");
tr.append("<td>" + json[i].userId + "</td>");
tr.append("<td>" + json[i].title + "</td>");
tr.append("<td>" + json[i].body + "</td>");
tr.append("<td><input type='button' value='edit' id='edit' onclick='myfunc(" + i + ")' /></td>");
$('#myTable').append(tr);
}
});
});
function myfunc(rowindex) {
rowindex++;
console.log(currentEditedIndex)
if (currentEditedIndex != -1) { //not first time to click
cancelClick(rowindex)
}
else {
cancelClick(currentEditedIndex)
}
currentEditedIndex = rowindex; //update the global variable to current edit location
//get cells values
var cell1 = ($("#myTable tr:eq(" + (rowindex) + ") td:eq(0)").text());
var cell2 = ($("#myTable tr:eq(" + (rowindex) + ") td:eq(1)").text());
var cell3 = ($("#myTable tr:eq(" + (rowindex) + ") td:eq(2)").text());
var cell4 = ($("#myTable tr:eq(" + (rowindex) + ") td:eq(3)").text());
//remove text from previous click
//add a cancel button
$("#myTable tr:eq(" + (rowindex) + ") td:eq(4)").append(" <input type='button' onclick='cancelClick("+rowindex+")' id='cancelBtn' value='Cancel' />");
$("#myTable tr:eq(" + (rowindex) + ") td:eq(4)").css("width", "200");
//make it a text box
$("#myTable tr:eq(" + (rowindex) + ") td:eq(0)").html(" <input type='text' id='mycustomid' value='" + cell1 + "' style='width:30px' />");
$("#myTable tr:eq(" + (rowindex) + ") td:eq(1)").html(" <input type='text' id='mycustomuserId' value='" + cell2 + "' style='width:30px' />");
$("#myTable tr:eq(" + (rowindex) + ") td:eq(2)").html(" <input type='text' id='mycustomtitle' value='" + cell3 + "' style='width:130px' />");
$("#myTable tr:eq(" + (rowindex) + ") td:eq(3)").html(" <input type='text' id='mycustomedit' value='" + cell4 + "' style='width:400px' />");
}
//on cancel, remove the controls and remove the cancel btn
function cancelClick(indx)
{
//console.log('edit is at row>> rowindex:' + currentEditedIndex);
indx = currentEditedIndex;
var cell1 = ($("#myTable #mycustomid").val());
var cell2 = ($("#myTable #mycustomuserId").val());
var cell3 = ($("#myTable #mycustomtitle").val());
var cell4 = ($("#myTable #mycustomedit").val());
$("#myTable tr:eq(" + (indx) + ") td:eq(0)").html(cell1);
$("#myTable tr:eq(" + (indx) + ") td:eq(1)").html(cell2);
$("#myTable tr:eq(" + (indx) + ") td:eq(2)").html(cell3);
$("#myTable tr:eq(" + (indx) + ") td:eq(3)").html(cell4);
$("#myTable tr:eq(" + (indx) + ") td:eq(4)").find('#cancelBtn').remove();
}
</script>
This is the essential point although you don't need to make the code this messy. Instead you could just iterate through all the <td> and add the <input> with the attributes and finally put in the values.
function edit(el) {
el.childNodes[0].removeAttribute("disabled");
el.childNodes[0].focus();
window.getSelection().removeAllRanges();
}
function disable(el) {
el.setAttribute("disabled","");
}<table border>
<tr>
<td ondblclick="edit(this)"><input value="cell1" disabled onblur="disable(this)"></td>
<td ondblclick="edit(this)"><input value="cell2" disabled onblur="disable(this)"></td>
<td ondblclick="edit(this)"><input value="cell3" disabled onblur="disable(this)"></td>
<td ondblclick="edit(this)"><input value="so forth..." disabled onblur="disable(this)">
</td>
</tr>
