You can use this code to add to your tag.
您可以使用此代码添加到您的标签中。
var myoption = document.createElement("option");
myoption.setAttribute("value", "carvalue");
var text = document.createTextNode("maruti");

There was a change in DOM implementation. Before, you could create a new element with the code inside, for instance:
DOM 实现发生了变化。之前，您可以创建一个包含代码的新元素，例如：
BAD
坏的
var anElement = document.createElement("<A HREF=\"http://stackoverflow.com \">StackOverflow</A>")
This implementation now, returns this ‘InvalidCharacterError'. What you must do now is to create the element and to populate it using the innerHTML attribute or the different specific attributes for any node.
现在，此实现返回此“InvalidCharacterError”。您现在必须做的是创建元素并使用 innerHTML 属性或任何节点的不同特定属性填充它。
GOOD
好的
var anElement = document.createElement("a")
anElement.innerHTML = ("<A HREF=\"http://stackoverflow.com \">StackOverflow</A>")
