Sibling node _ javascript skills in DOM Script Programming

You can use the previussibling and nextSibling attributes between sibling nodes to access different subnodes at the same level. What if this sibling node is an element or a text node running on a modern browser? Except IE, the browser uses a line break as the text node of the content (nodeType is 3 ). If it is an element, nodeType is 1. The following is a practical method to find them:

The Code is as follows:

LastSibling: function (node ){
Var tempObj = node. parentNode. lastChild;
While (tempObj. nodeType! = 1 & tempObj. previussibling! = Null)
{
TempObj = tempObj. previussibling;
}
Return (tempObj. nodeType = 1 )? TempObj: false;
}

This is the source code of the lastSibling method in the DOMhelp library in JavaScript. Similar to the source code in the mootools Library:

The Code is as follows:

'Last-child ': function (){
Var element = this;
While (element = element. nextSibling )){
If (element. nodeType = 1) return false;
}
Return true;
}

This is the last-child () method in the source code of Mootools 1.2.4.
