Extjs is displayed normally in Firefox, but an error is returned when you open it with IE: the object does not support this attribute or method (Object doesn't support this property or method ).
I found it online. This is an issue in IE where the first element of the body can't be a text node.
The first element in the original body label cannot be text. Otherwise, the IE browser reports an error. That is to say, <body> must be followed by Div, span, table, form, and other block elements or in-row elements, that is, it cannot be any type of text. In fact, when using Ext, it is better not to show the nodes in this article separately. If you are not sure when an error will occur, you 'd better use element packages such as <p>. Source code to be studied for specific reasons.
It turns out that my <body> label is <% = request. getcontextpath () %>, which is a text. No wonder ie reports an error.
