javascript Summernote：初始化后设置焦点

Summernote: set focus after initialization

提问by lsouza

Summernotegives you the option of giving focus to the editor when you create it, passing this options:

Summernote为您提供了在创建编辑器时为其提供焦点的选项，传递以下选项：

$('#summernote').summernote({
     focus: true
});

But after initialization, it seems you can't give focus to the textarea by clicking a button or similar. I've tried several ways, without success.

但是初始化后，似乎您无法通过单击按钮或类似按钮将焦点放在 textarea 上。我尝试了几种方法，都没有成功。

Anyone did that?

有人这样做过吗？

After coming back to this problem and trying a lot of solutions, I came to one that works:

在回到这个问题并尝试了很多解决方案之后，我找到了一个有效的方法：

$('.note-editable').trigger('focus');

$('.note-editable').trigger('focus');

Triggering the event through jQuery works, but using the focus()function doesn't.

通过 jQuery 触发事件有效，但使用该focus()函数则无效。

$(document).ready(function () {
                        $.fn.extend({
                            placeCursorAtEnd: function () {
                                // Places the cursor at the end of a contenteditable container (should also work for textarea / input)
                                if (this.length === 0) {
                                    throw new Error("Cannot manipulate an element if there is no element!");
                                }
                                var el = this[0];
                                var range = document.createRange();
                                var sel = window.getSelection();
                                var childLength = el.childNodes.length;
                                if (childLength > 0) {
                                    var lastNode = el.childNodes[childLength - 1];
                                    var lastNodeChildren = lastNode.childNodes.length;
                                    range.setStart(lastNode, lastNodeChildren);
                                    range.collapse(true);
                                    sel.removeAllRanges();
                                    sel.addRange(range);
                                }
                                return this;
                            }
                        });
                    });

then：

然后：

$('.note-editable').click(function(){
                                  //$('#summernote').summernote('focus');
                                  $(this).placeCursorAtEnd();
                                });

①focus on click or tap ②focus at the end of content

①关注点击或点击 ②关注内容末尾

it works on mobile device too

它也适用于移动设备

You can set the focus by putting the focus on the editable divused by Summernote:

您可以通过将焦点放在Summernote 使用的可编辑 div上来设置焦点：

document.querySelectorAll(".note-editable").focus();

or using JQuery

或使用 JQuery

$('#summernote').find('.note-editable').focus();
