function getSelectionHtml() {
var html = "";
if (typeof window.getSelection != "undefined") {
var sel = window.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
} else if (typeof document.selection != "undefined") {
if (document.selection.type == "Text") {
html = document.selection.createRange().htmlText;
}
}
return html;
}
我正在使用上面提供的代码:How to get selected html text with javascript?。
然而,与函数返回的实际html和html存在不一致之处。例如,给出以下html:
<div>
<p><b>The quick brown fox jumps over the lazy <a href="www.google.com">dog</a></b></p>
<img src="http://www.fakingnews.firstpost.com/wp-content/uploads/2015/12/kim-jaya.jpg" alt="Smiley face" height="42" width="42">
<hr>
<p>The quick brown fox jumps over the lazy <a href="http://www.google.com">dog</a></p>
<li>
<ul>1</ul>
<ul>2</ul>
<ul>3</ul>
<ul>4</ul>
<ul>5</ul>
</li>
</div>
<br />
<input id="showSelected" type="button" value="showSelected" />
如果我要选择
x jumps over the lazy <a href="http://www.google.com">dog</a></p>
<li>
<ul>1</ul>
<ul>2</ul>
<ul>3</ul>
该函数实际返回
<div><p>x jumps over the lazy <a href="http://www.google.com">dog</a></p>
<li>
<ul>1</ul>
<ul>2</ul>
<ul>3</ul>
<ul>4</ul>
<ul>5</ul>
</li>
</div>
我注意到当我也选择列表时,前面会出现额外的标签,但我确定还有其他不一致的情况。我能做些什么来获得精确的HTML副本吗?

由于您选择的内容不是有效的HTML,例如缺少开始和结束标记,因此您在问题中列出的代码无法按预期工作, 在您的情况下,您需要使用文本选择功能,如:https://stackoverflow.com/a/169873/200713
function getSelectedText() {
var txt = '';
if (window.getSelection) {
txt = window.getSelection();
}
else if (document.getSelection) {
txt = document.getSelection();
}
else if (document.selection) {
txt = document.selection.createRange().text;
}
else return;
return txt;
}
