Cross-browser Javascript

If you use appendchild to add the <tr> element to <Table> directly, this line does not appear in IE, but is displayed in other browsers, the solution is to add the <tr> element to the <tbody> element of the table. This solution works correctly in all browsers. IE is also troublesome for the setattribute method. IE cannot use setattribute to correctly set the class attribute. There is a cross-browser solution for this, that is, setattribute ("class", "newclassname") and setattribute ("classname ", "newclassname "). In addition, you cannot use setattribute to set the style attribute in IE. The best technology to ensure browser compatibility is not <element>. setattribute ("style", "font-weight: bold"), but <element> .style.css text = "font-weight: bold ;".
