如何在CKEditor中将光标位置设置到文本末尾?

有没有办法将光标设置在 CKEditor 内容的末尾?

该开发人员也提出了问题,但没有收到答案:

http ://cksource.com/forums/viewtopic.php?f=11&t=19877&hilit=cursor+end

我想将焦点设置在 CKEditor 内文本的末尾。当我使用时:

ckEditor.focus();

它会将我带到 CKEditor 内已有文本的开头。

Is there a way to set the cursor to be at the end of the contents of a CKEditor?

This developer asked too, but received no answers:

http://cksource.com/forums/viewtopic.php?f=11&t=19877&hilit=cursor+end

I would like to set the focus at the end of the text inside a CKEditor. When I use:

ckEditor.focus();

It takes me to the beginning of the text already inside the CKEditor.

经过一番摆弄后,我已经让它可以使用以下代码:

$(document).ready(function() {

    CKEDITOR.on('instanceReady', function(ev) {

        ev.editor.focus();

        var s = ev.editor.getSelection(); // getting selection
        var selected_ranges = s.getRanges(); // getting ranges
        var node = selected_ranges[0].startContainer; // selecting the starting node
        var parents = node.getParents(true);

        node = parents[parents.length - 2].getFirst();

        while (true) {
            var x = node.getNext();
            if (x == null) {
                break;
            }
            node = x;
        }

        s.selectElement(node);
        selected_ranges = s.getRanges();
        selected_ranges[0].collapse(false);  //  false collapses the range to the end of the selected node, true before the node.
        s.selectRanges(selected_ranges);  // putting the current selection there
    }

});

这个想法是:

  1. 获取根节点(而不是主体)
  2. 前进到下一个节点,直到没有更多的节点可以前进到。
  3. 选择最后一个节点。
  4. 折叠
  5. 设置范围

After a bit of fiddling, I've got it to work with the following code:

$(document).ready(function() {

    CKEDITOR.on('instanceReady', function(ev) {

        ev.editor.focus();

        var s = ev.editor.getSelection(); // getting selection
        var selected_ranges = s.getRanges(); // getting ranges
        var node = selected_ranges[0].startContainer; // selecting the starting node
        var parents = node.getParents(true);

        node = parents[parents.length - 2].getFirst();

        while (true) {
            var x = node.getNext();
            if (x == null) {
                break;
            }
            node = x;
        }

        s.selectElement(node);
        selected_ranges = s.getRanges();
        selected_ranges[0].collapse(false);  //  false collapses the range to the end of the selected node, true before the node.
        s.selectRanges(selected_ranges);  // putting the current selection there
    }

});

The idea is:

  1. Get the root node (not body)
  2. Advance to next node, until there are no more nodes to advance to.
  3. Select last node.
  4. Collapse it
  5. Set range

这是@peter-tracey 的类似答案。就我而言,我的插件正在插入引用。如果用户做出了选择,我需要禁用该选择并将光标放在句子的末尾。

  // Obtain the current selection & range
  var selection = editor.getSelection();
  var ranges = selection.getRanges();
  var range = ranges[0];

  // Create a new range from the editor object
  var newRange = editor.createRange();

  // assign the newRange to move to the end of the current selection
  // using the range.endContainer element.
  var moveToEnd = true;
  newRange.moveToElementEditablePosition(range.endContainer, moveToEnd);

  // change selection
  var newRanges = [newRange];
  selection.selectRanges(newRanges);

  // now I can insert html without erasing the previously selected text.
  editor.insertHtml("<span>Hello World!</span>");

Here's a similar answer to @peter-tracey. In my case my plugin is inserting a citation. If the user has made a selection, I needed to disable the selection and place the cursor at the end of the sentence.

  // Obtain the current selection & range
  var selection = editor.getSelection();
  var ranges = selection.getRanges();
  var range = ranges[0];

  // Create a new range from the editor object
  var newRange = editor.createRange();

  // assign the newRange to move to the end of the current selection
  // using the range.endContainer element.
  var moveToEnd = true;
  newRange.moveToElementEditablePosition(range.endContainer, moveToEnd);

  // change selection
  var newRanges = [newRange];
  selection.selectRanges(newRanges);

  // now I can insert html without erasing the previously selected text.
  editor.insertHtml("<span>Hello World!</span>");

CKEditor 3.x:

on : {
        'instanceReady': function(ev) {
           ev.editor.focus();
           var range = new CKEDITOR.dom.range( ev.editor.document );
           range.collapse(false);
           range.selectNodeContents( ev.editor.document.getBody() );
           range.collapse(false);
           ev.editor.getSelection().selectRanges( [ range ] );
        }
     }

基于开发人员提供的伪代码:

https://dev .ckeditor.com/ticket/9546#comment:3

你必须聚焦编辑器,获取文档对象,将其放入范围内,
折叠范围(带有 false 参数),选择正文(带有
selectNodeContents),折叠它(使用 false 参数),最后
选择范围。最好在instanceReady事件中完成这一切。

CKEditor 3.x:

on : {
        'instanceReady': function(ev) {
           ev.editor.focus();
           var range = new CKEDITOR.dom.range( ev.editor.document );
           range.collapse(false);
           range.selectNodeContents( ev.editor.document.getBody() );
           range.collapse(false);
           ev.editor.getSelection().selectRanges( [ range ] );
        }
     }

based on pseudo-code provided by the developers here:

https://dev.ckeditor.com/ticket/9546#comment:3

You have to focus editor, get document object, put it in range,
collapse range (with false parameter), select body (with
selectNodeContents), collapse it (with false parameter) and finally
select range. It is best to do it all in instanceReady event.

这是 ckeditor API 提供的最简单的解决方案。我已经在 IE10+、ff、safari 和 Chrome 上测试过:

range = editor.createRange();
// the first parameter is the last line text element of the ckeditor instance
range.moveToPosition(new CKEDITOR.dom.node(editor.element.$.children[pos - 1]), CKEDITOR.POSITION_BEFORE_END)
range.collapse()
editor.getSelection().selectRanges([ range ])

This is the easiest solution provided by the ckeditor API. I have tested it on IE10+, ff, safari and Chrome:

range = editor.createRange();
// the first parameter is the last line text element of the ckeditor instance
range.moveToPosition(new CKEDITOR.dom.node(editor.element.$.children[pos - 1]), CKEDITOR.POSITION_BEFORE_END)
range.collapse()
editor.getSelection().selectRanges([ range ])

这肯定会起作用。
CKEDITOR.config.startupFocus = '结束';

This will work for sure.
CKEDITOR.config.startupFocus = 'end';

您是否尝试过 ckEditor.Selection.Collapse(false);

have you tried ckEditor.Selection.Collapse(false);

根据 CKEditor 4 文档,另一个选项是:

const range = this.ckeditor.createRange()
range.moveToElementEditablePosition(range.root, true)
this.ckeditor.getSelection().selectRanges([range])

链接: https: //ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_range.html#method-moveToElementEditablePosition

According to CKEditor 4 documentation, another option is:

const range = this.ckeditor.createRange()
range.moveToElementEditablePosition(range.root, true)
this.ckeditor.getSelection().selectRanges([range])

Link: https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_dom_range.html#method-moveToElementEditablePosition

丹的回答对我来说得到了奇怪的结果,但微小的改变(除了拼写错误修复之外)使它起作用:

var range = me.editor.createRange();
range.moveToElementEditEnd( range.root );
me.editor.getSelection().selectRanges( [ range ] );

Dan's answer got strange results for me, but minor change (in addition to typo fix) made it work:

var range = me.editor.createRange();
range.moveToElementEditEnd( range.root );
me.editor.getSelection().selectRanges( [ range ] );

根据 CKEditor 4 的文档,一旦拥有编辑器对象,您就可以执行以下操作。

var range = editor.createRange();
range.moveToPosition( range.root, CKEDITOR.POSITION_BEFORE_END );
editor.getSelection().selectRanges( [ range ] );

链接:http://docs.ckeditor.com/#!/api/CKEDITOR.dom.selection< /a> (在 selectRanges 函数下)。

According to the documentation for CKEditor 4, you can do the following once you have the editor object.

var range = editor.createRange();
range.moveToPosition( range.root, CKEDITOR.POSITION_BEFORE_END );
editor.getSelection().selectRanges( [ range ] );

Link: http://docs.ckeditor.com/#!/api/CKEDITOR.dom.selection (under selectRanges function).
