我想使用下面的函数来获取当前选择的文本(来源:javascript replace selection all browsers)。
在我的情况下,我不想替换选定的文本,而是想在它之前和之后添加一些东西,主要是 HTML 标签(通过点击一个按钮)。
示例:
所选文本 = Hello 新文本 (html) =<u>Hello</u>
获取选定文本的代码:
function replaceSelection(html) {
var sel, range, node;
if (typeof window.getSelection != "undefined") {
// IE 9 and other non-IE browsers
sel = window.getSelection();
// Test that the Selection object contains at least one Range
if (sel.getRangeAt && sel.rangeCount) {
// Get the first Range (only Firefox supports more than one)
range = window.getSelection().getRangeAt(0);
range.deleteContents();
// Create a DocumentFragment to insert and populate it with HTML
// Need to test for the existence of range.createContextualFragment
// because it's non-standard and IE 9 does not support it
if (range.createContextualFragment) {
node = range.createContextualFragment(html);
} else {
// In IE 9 we need to use innerHTML of a temporary element
var div = document.createElement("div"), child;
div.innerHTML = html;
node = document.createDocumentFragment();
while ( (child = div.firstChild) ) {
node.appendChild(child);
}
}
range.insertNode(node);
}
} else if (document.selection && document.selection.type != "Control") {
// IE 8 and below
range = document.selection.createRange();
range.pasteHTML(html);
}
}
调用函数的代码:
replaceSelection('<span><font color="red">hoho</font></span>');
有人可以告诉我如何通过修改上述内容来实现这一目标吗?
非常感谢您对此提供的任何帮助,蒂姆。
