如何向 Quill.js 添加新格式(<hr> 标签)? [英] How can I add a new format (<hr> tag) to Quill.js?
问题描述
我想添加一个按钮,该按钮会将 <hr>
标记添加到 羽毛笔.js(测试版) 编辑器.
这里是小提琴.
<div id="工具栏-容器"><span class="ql-formats"><button class="ql-hr"></button>//这里是我的人力资源按钮</span><span class="ql-formats"><button class="ql-bold"></button><button class="ql-italic"></button></span>
<div id="编辑器"><p>你好世界!</p><小时>//这被替换为 <p>自动标记*奇怪*<p>一些初始的<strong>粗体</strong>文本
我初始化我的编辑器:
var quill = new Quill('#editor', {模块:{工具栏:'#toolbar-container'},placeholder: '撰写史诗...',主题:雪"});
在这里,我向我的编辑器添加了 标签功能,并且效果很好:
$('.ql-hr').on("click",function(){var range = quill.getSelection();var text = quill.getText(range.index, range.length);quill.deleteText(range.index, range.length);quill.pasteHTML(range.index, '<h1>'+text+'</h1>');})
现在我对 <hr>
标签尝试相同的方法,但它根本不起作用:
$('.ql-hr').on("click",function(){var range = quill.getSelection();quill.pasteHTML(range.index, '<hr>');})
初始 div#editor
中的
标签被替换为 标签.我添加的按钮功能对
<hr>
标签不起作用,但对于其他标签它起作用.我知道 <hr>
标签没有在 Quill.js 中实现,这也是我得到这个控制台输出的原因:
quill:toolbar 忽略附加到不存在的格式 hr select.ql-hr
有什么办法可以解决这个问题吗?
我仍然不知道为什么这个问题被否决了,但是这里是解决方案:
导入嵌入 blot - 重要:不是阻止",不是嵌入"、阻止/嵌入"!
var Embed = Quill.import('blots/block/embed');
定义一个扩展 Embed 的新类
class Hr extends Embed {静态创建(值){让节点 = super.create(value);//给它一些余量node.setAttribute('style', "height:0px; margin-top:10px; margin-bottom:10px;");返回节点;}}
定义你的标签
Hr.blotName = 'hr';//现在您可以在工具栏中使用 .ql-hr 类名hr.className = 'my-hr';hr.tagName = 'hr';
为 <hr> 编写自定义处理程序按钮
var customHrHandler = function(){//获取光标位置var range = quill.getSelection();如果(范围){//插入<hr>光标在哪里quill.insertEmbed(range.index,"hr","null")}}
注册您的新格式
Quill.register({'格式/小时':小时});
在 HTML 中使用正确的选择器实例化您的编辑器
var quill = new Quill('#editor', {模块:{工具栏:{容器:'#toolbar-container',处理程序:{'hr':customHrHandler}}},主题:雪"});
HTML 部分保持不变.整个<hr>功能可以类似于 <img>格式.

I want to add a button which would add a <hr>
tag to the quill.js (beta) editor.
Here the fiddle.
<!-- Initialize Quill editor -->
<div id="toolbar-container">
<span class="ql-formats">
<button class="ql-hr"></button> //here my hr-button
</span>
<span class="ql-formats">
<button class="ql-bold"></button>
<button class="ql-italic"></button>
</span>
</div>
<div id="editor">
<p>Hello World!</p>
<hr> // this gets replaced by <p> tag automatically *strange*
<p>Some initial <strong>bold</strong> text</p>
</div>
I initialize my editor:
var quill = new Quill('#editor', {
modules: {
toolbar: '#toolbar-container'
},
placeholder: 'Compose an epic...',
theme: 'snow'
});
Here I add a <h1>
tag functionality to my editor and it works very well:
$('.ql-hr').on("click",function(){
var range = quill.getSelection();
var text = quill.getText(range.index, range.length);
quill.deleteText(range.index, range.length);
quill.pasteHTML(range.index, '<h1>'+text+'</h1>');
})
Now I try the same for a <hr>
tag, which doesn't work at all:
$('.ql-hr').on("click",function(){
var range = quill.getSelection();
quill.pasteHTML(range.index, '<hr>');
})
the <hr>
tag in the initial div#editor
gets replaced with a <p>
tag. And the button functionality I added doensn't work for <hr>
tags, but for other tags it works. I know the <hr>
tag is not implemented to Quill.js, that's also why I get this console output:
quill:toolbar ignoring attaching to nonexistent format hr select.ql-hr
Is there any way to fix this?
I have still no idea why the question has downvotes, but however here is the solution:
Import the embed blot - important: not "block", not "embed", "block/embed"!
var Embed = Quill.import('blots/block/embed');
Define a new class that extends that Embed
class Hr extends Embed {
static create(value) {
let node = super.create(value);
// give it some margin
node.setAttribute('style', "height:0px; margin-top:10px; margin-bottom:10px;");
return node;
}
}
Define your tag
Hr.blotName = 'hr'; //now you can use .ql-hr classname in your toolbar
Hr.className = 'my-hr';
Hr.tagName = 'hr';
Write a custom handler for the <hr> button
var customHrHandler = function(){
// get the position of the cursor
var range = quill.getSelection();
if (range) {
// insert the <hr> where the cursor is
quill.insertEmbed(range.index,"hr","null")
}
}
Register your new format
Quill.register({
'formats/hr': Hr
});
Instantiate your Editor with the right selectors in your HTML
var quill = new Quill('#editor', {
modules: {
toolbar: { container: '#toolbar-container',
handlers: {
'hr': customHrHandler
}
}
},
theme: 'snow'
});
The HTML part remains the same. The whole <hr> functionality can be done similar to the <img> format.
