Create an issue with jquery that does not exist in the HTML tag element

If you customize a label, such as <aaa></aaa>

Using jquery, such as var custom_element = $ (' <aaa class= ' ee ></aaa> ');

There is no problem building the object, but if you add elements such as custom_element.append (' <div>ok</div> ') to the object, an exception is thrown under IE8: "The method or property access is called unexpectedly." ”

If only $ (' <aaa></aaa ') is generated, it will not be an exception, but adding attributes such as class will cause problems.

There are two solutions: 1. Take the class out, use jquery to create only the elements, and then modify the properties of the custom tags, such as addclass and attr.

2. Use the $ (document.createelement (' AA ')) method to convert the native JS created object to a jquery object, and then modify the properties of the custom element using methods such as AddClass or attr.

3. Using IE9 or later browsers
