应打印(b)应打印(/b)应打印

This should print(b)This should print(/b)This should print

<script>
function produceMessage(){
    var msg= '<b>This should print</b>';
    return msg;
}

<span id="mySpan"></span>

<script>

    document.body.appendChild(document.createTextNode(produceMessage()));

推荐答案

否，文本节点不会打印任何HTML.而是创建一个元素，或使用文档片段以这种方式插入HTML.

No, a text node will not print any HTML. Instead, create an element, or use a document fragment to insert HTML in that way.

function boldHTML() {
  var element = document.createElement("b");
  element.innerHTML = "Bold text";
  return element;
}
document.body.appendChild(boldHTML());

将打印粗体.
