在元素中的选定文本周围添加标签 [英] Add tags around selected text in an element
问题描述
如何在元素中的所选文本周围添加< span>
标记?
How can I add <span>
tags around selected text within an element?
例如,如果有人突出显示John,我想在其周围添加span标签。
For example, if somebody highlights "John", I would like to add span tags around it.
HTML
<p>My name is Jimmy John, and I hate sandwiches. My name is still Jimmy John.</p>
JS
function getSelectedText() {
t = (document.all) ? document.selection.createRange().text : document.getSelection();
return t;
}
$('p').mouseup(function(){
var selection = getSelectedText();
var selection_text = selection.toString();
console.log(selection);
console.log(selection_text);
// How do I add a span around the selected text?
});
这里有一个相同的问题: jQuery选择文本并在段落中添加跨度,但它使用过时的jquery方法(例如,直播),并且接受的答案有一个错误。
There is a identical question here: jQuery select text and add span to it in an paragraph, but it uses outdated jquery methods (e.g. live), and the accepted answer has a bug.
推荐答案
我有一个解决方案。获取它的selecion和deleteContent的范围
,然后在其中插入一个新的 span
。
I have a solution. Get the Range
of the selecion and deleteContent of it, then insert a new span
in it .
$('body').mouseup(function(){
var selection = getSelectedText();
var selection_text = selection.toString();
// How do I add a span around the selected text?
var span = document.createElement('SPAN');
span.textContent = selection_text;
var range = selection.getRangeAt(0);
range.deleteContents();
range.insertNode(span);
});
你可以看到此处的演示
更新
绝对地,选择将同时被删除。因此,如果需要,可以使用js代码添加选择范围。
Absolutly, the selection will be delete at the same time. So you can add the selection range with js code if you want.
