var source = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
var html = xss(source, {
onIgnoreTagAttr: function (tag, name, value, isWhiteAttr) {
if (name.substr(0, 5) === 'data-') {
// 通过内置的escapeAttrValue函数来对属性值进行转义
return name + '="' + xss.escapeAttrValue(value) + '"';
}
}
});
console.log('%s\nconvert to:\n%s', source, html);
运行结果:
<div a="1" b="2" data-a="3" data-b="4">hello</div>
convert to:
<div data-a="3" data-b="4">hello</div>
