Question about textNode sharding in FireFox _ javascript skills

TextNode fragment in FireFox. A common behavior in Ajax applications is to wrap data in XML in the background and return it to the browser. The browser parses XML to obtain nodeValue.

If the content of a single node is long (more than 4096 bytes), you should note that the content will be divided into multiple textnodes by FrieFox, each of which is 4096 bytes. In this case, the following functions can be used for processing (IE compatibility)

The Code is as follows:

Function getNodeValue (node)
{
If (node & node. hasChildNodes ()){
// Return node. firstChild. nodeValue;
Var s = ""
// Mozilla has extends textnodes with a size of 4096
// Chars each instead of one large one.
// They all need to be concatenated.
For (var j = 0; j S + = new String (node. childNodes. item (j). nodeValue );
}
Return s;
} Else
Return "";
}
