在contentEditable中将HTML转换为纯文本 [英] Convert HTML to plain text in contentEditable
问题描述
我有一个 contentEditable
,并通过捕获('paste')来剥离粘贴内容的格式事件。然后我关注一个textarea,将内容粘贴在那里,然后复制该值。几乎从这里得到的答案。问题是我不能这样做:
$(#paste-output)。text($( #area)VAL())。
,因为这会将我的整个内容替换为粘贴的文字。所以我需要将内容粘贴到插入位置。我将一个脚本放在一起:
pasteHtmlAtCaret($(#area)。val());
//在CTRL位置粘贴CTRL + V内容
函数pasteHtmlAtCaret(html){
var sel,range;
if(window.getSelection){
sel = window.getSelection();
if(sel.getRangeAt&& sel.rangeCount){
range = sel.getRangeAt(0);
range.deleteContents();
var el = document.createElement(div);
el.innerHTML = html;
var frag = document.createDocumentFragment(),node,lastNode; ((node = el.firstChild)){
lastNode = frag.appendChild(node);
while
}
range.insertNode(frag);
if(lastNode){
range = range.cloneRange();
range.setStartAfter(lastNode);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
$ b} else if(document.selection&& document.selection.type!=Control){
document.selection.createRange()。pasteHTML (HTML);
$ b 唯一的问题是它粘贴HTML内容,插入符号位置使用 html
变量。我怎样才能将它转换成纯文本?我尝试将jQuery .text(html)
添加到变量中,但没有运气。像这样的东西可能会有所帮助:
el.textContent || el.innerText;
任何想法或更好的解决方案?谢谢!
编辑:
感谢下面的答案,我修改了我的代码并解决了这个问题。我基本上把 textarea
的值复制到 div
中,并且只抓取它的 .text() :
//粘贴时,从HTML标签剥离剪贴板(如果有的话)
$ ()#post_title,#post_content')。on(paste,function(){
var text = $('< div>)。html($(#area).val()) .text();
pasteHtmlAtCaret(text);
},20);
});

感谢上面的答案,我修改了我的代码并解决了问题。我基本上把textarea的值复制到一个div中,并且只抓取它的.text():
pre> //在粘贴,剪贴板上如果有任何
$('#post_title,#post_content')。on(paste,function(){
setTimeout(function(){
var text = $(' < div>)。html($(#area).val()).text();
pasteHtmlAtCaret(text);
},20);
}) ;
I have a contentEditable
and I strip the formatting of pasted content on('paste')
by catching the event. Then I focus a textarea, paste the content in there, and copy the value. Pretty much the answer from here. The problem is that I can’t do this:
$("#paste-output").text($("#area").val());
because that would replace my entire content with the pasted text. So I need to paste the content at caret position. I put together a script that does that:
pasteHtmlAtCaret($("#area").val());
// pastes CTRL+V content at caret position
function pasteHtmlAtCaret(html) {
var sel, range;
if (window.getSelection) {
sel = window.getSelection();
if (sel.getRangeAt && sel.rangeCount) {
range = sel.getRangeAt(0);
range.deleteContents();
var el = document.createElement("div");
el.innerHTML = html;
var frag = document.createDocumentFragment(), node, lastNode;
while ((node = el.firstChild)) {
lastNode = frag.appendChild(node);
}
range.insertNode(frag);
if (lastNode) {
range = range.cloneRange();
range.setStartAfter(lastNode);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
}
}
} else if (document.selection && document.selection.type != "Control") {
document.selection.createRange().pasteHTML(html);
}
}
The only problem is that it pastes HTML content, at caret position using the html
variable. How can I transform that into plain text? I tried adding the jQuery .text(html)
to variable without luck. Something like this might help:
el.textContent||el.innerText;
Any ideas or a better solution? Thanks!
EDIT:
Thanks to the answers below I modified my code and solved the issue. I basically copied the value of textarea
into a div
and grabbed only its .text()
:
// on paste, strip clipboard from HTML tags if any
$('#post_title, #post_content').on("paste", function() {
var text = $('<div>').html($("#area").val()).text();
pasteHtmlAtCaret(text);
}, 20);
});
