我有一个可以理解的div,我希望用户能够插入链接,图片或YouTube视频等内容。目前这就是我所拥有的:
link = $('#url')。val(); $(#编者)专注()。 document.execCommand('createLink',false,link);}
< script src =ajax.googleapis/ajax/libs/jquery/2.1.1/jquery.min.js>< / script><! - 文字编辑器 - >< div id =editorcontenteditable =true>< / div><! - Add Link - >< input type =textid =url><按钮onclick =addLink()> Submit< / button>
正如你所看到的,用户必须输入一个单独的文本框才能输入链接地址。因此,当链接添加到编辑器时,它不会添加到指针/插入符号所在的位置。
我的问题是我如何获得并设置指针/插入符号的位置。我看过其他问题,例如用于设置指针,但我更喜欢有一个在所有现代浏览器中都支持的解决方案,包括Chrome,Safari,Firefox和IE9 +。
任何想法? $ b
编辑:
我发现下面的代码获取位置但是,它只能根据它所在的线路获取位置。例如,如果我有这个(其中 | 是游标):
这是一些文本和som | e更多文本然后我将返回值为7,而不是24。
函数getPosition(){ if(window.getSelection){ sel = window.getSelection(); if(sel.getRangeAt){ return sel.getRangeAt(0).startOffset; } } 返回null; }解决方案
是当前要做的更难的事情之一,并且本身就是一个项目(不友好的API,大量的角落案例,跨浏览器差异,名单继续)。我强烈建议您尝试找到现有解决方案。
可以使用的一些库包括:
- Quill( quilljs )
- WYSGIHTML( wysihtml )
- CodeMirror库( codemirror )
I have a contenteditable div which I would like to be able to have users insert things such as links, images or YouTube videos. At the moment this is what I have:
function addLink() { var link = $('#url').val(); $('#editor').focus(); document.execCommand('createLink', false, link); }<script src="ajax.googleapis/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <!-- Text Editor --> <div id="editor" contenteditable="true"></div> <!-- Add Link --> <input type="text" id="url"> <button onclick="addLink()">Submit</button>
As you can see, the user has to type into a separate text box to enter the link address. As a result, when the link is added to the editor, it is not added to the position that the pointer/caret was on.
My question is how I can get and set the location of the pointer/caret. I have seen other questions such as this for setting the pointer however I would prefer to have a solution which is supported in all modern browsers, including Chrome, Safari, Firefox and IE9+.
Any ideas? Thanks.
Edit:
I found the code below which gets the position however, it only gets the position according to the line it is on. For example if I had this (where | is the cursor):
This is some text And som|e more textThen I would be returned the value 7, not 24.
function getPosition() { if (window.getSelection) { sel = window.getSelection(); if (sel.getRangeAt) { return sel.getRangeAt(0).startOffset; } } return null; }解决方案
A good rich-text editor is one of the harder things to do currently, and is pretty much a project by itself (unfriendly API, huge number of corner cases, cross-browser differences, the list goes on). I would strongly advise you to try and find an existing solution.
Some libraries that can be used include:
- Quill (quilljs)
- WYSGIHTML (wysihtml)
- CodeMirror library (codemirror)
