问题
I have an html text like:
'<div class="a"><span>1</span><div>2</div></div>'
Is there a function in closure library to get such a string as input and return a DOM tree to insert in a document?
回答1:
Closure Library provides the function goog.dom.safeHtmlToNode(html) to create a document fragment (Node) from a goog.html.SafeHtml object, which can be created using goog.html.sanitizer.HtmlSanitizer as shown below.
Example
<!doctype html>
<html>
<head>
<title>Closure Library Dom Test</title>
<script src="https://cdn.rawgit.com/google/closure-library/master/closure/goog/base.js"></script>
<script>
goog.require('goog.dom');
goog.require('goog.html.SafeHtml');
goog.require('goog.html.sanitizer.HtmlSanitizer');
</script>
</head>
<body>
<h1>Closure Library Dom Test</h1>
<div id="main">
</div>
<script>
var sanitizer = new goog.html.sanitizer.HtmlSanitizer.Builder().build();
var fragment = goog.dom.safeHtmlToNode(
sanitizer.sanitize('<div class="a"><span>1</span><div>2</div></div>'));
goog.dom.append(/** @type {!Node} */(document.querySelector('#main')),
/** @type {!Node} */(fragment));
</script>
</body>
</html>
