如何使HTML表格单元格可编辑?

标签: html editor html-table cell

我想让html表的一些单元格可编辑,只需双击一个单元格,输入一些文本即可将更改发送到服务器。我不想使用像dojo数据网格这样的工具包。因为它提供了一些其他功能。您能否提供一些代码片段或有关如何实现它的建议?

您可以对相关的单元格,行或表使用contenteditable属性。

针对IE8兼容性进行了更新

<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>

请注意,如果您使表格可编辑,至少在Mozilla中,您可以删除行等。

您还需要检查目标受众的浏览器是否支持此属性。

至于收听更改(以便您可以发送到服务器),请参阅contenteditable change events

答案 1 :(得分:43)

HTML5支持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>

第三方编辑

引用mdn entry on contenteditable

  

该属性必须采用以下值之一:

     
      
  • true或空字符串,表示该元素必须可编辑;

  •   
  • false,表示该元素不得编辑。

  •   
     

如果未设置此属性,则从其继承其默认值   父元素。

     

此属性是枚举属性,而不是布尔属性。这意味着   明确使用其中一个值为true,false或为空   string是必需的,并且不允许使用简写...

// wrong not allowed
<label contenteditable>Example Label</label> 

// correct usage
<label contenteditable="true">Example Label</label>.

我有三种方法, 您可以根据自己的要求同时使用Submitting with '<unnamed>' Error: not compatible with STRSXP <input>

<强> 1。使用<textarea>中的输入。

在所有<td>中使用<input>元素,

<td>

此外,您可能希望将输入调整为其<tr><td><input type="text"></td>....</tr> 的大小。离。,

td

您可以在未编辑时更改输入框边框的颜色。

<强> 2。使用input { width:100%; height:100%; } 属性。 (HTML5)

但是,如果要使用contenteditable='true',可能还需要将适当的值保存到数据库中。你可以用ajax实现这个目的。

您可以将关键代码contenteditable='true'keyupkeydown等附加到keypress。此外,当用户连续输入时,对这些事件使用一些delay()是很好的,ajax事件不会在每个关键用户按下时触发。例如,

<td>

第3。单击时将$('table td').keyup(function() { clearTimeout($.data(this, 'timer')); var wait = setTimeout(saveData, 500); // delay after user types $(this).data('timer', wait); }); function saveData() { // ... ajax ... } 附加到<input>

单击<td>时在td中添加输入元素,根据<td>的值替换其值。输入模糊时,请使用输入值更改`td&#39; s值。所有这一切都与javascript。

试试这段代码。

$(function () {
 $("td").dblclick(function () {
    var OriginalContent = $(this).text();

    $(this).addClass("cellEditing");
    $(this).html("<input type="text" value="&quot; + OriginalContent + &quot;" />");
    $(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");
 });
 });
});

我正在将其用于可编辑字段

答案 10 :(得分:0)

这是必不可少的,尽管您不需要使代码变得混乱。相反,您可以遍历所有<td>并添加带有属性的<input>,最后输入值。

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>

点击<input><td>。 当其模糊时,将<input>更改为<span>

如果你的表格有很多功能(排序、导出、更新、编辑等),

我会推荐引导表。

关于编辑实践:

侦听事件:click-cell.bs.table 然后在单击时将属性 contenteditable 添加到 td

您可能不想允许在每一列中进行编辑,因此我自己使用 JS 添加了 data-editable 属性来确定这一点。
