Javascript implementation of TreeView non-refresh expansion example code_javascript skills

Copy code The code is as follows:

function public_GetParentByTagName(element, tagName)
{
var parent = element.parentNode;
var upperTagName = tagName.toUpperCase();
//If this element is not wanted yet Continue tracing up to the tag you want
while (parent && (parent.tagName.toUpperCase() != upperTagName))
{
parent = parent.parentNode ? parent.parentNode : parent.parentElement;
}
Return parent;
}
//Set the node's parent node Cheched - if the node is accessible, its parent node must also be accessible
function setParentChecked(objNode)
{
var objParentDiv = public_GetParentByTagName(objNode,"div");
if(objParentDiv==null || objParentDiv == "undefined")
{
return;
}
var objID = objParentDiv.getAttribute("ID");
objID = objID.substring(0,objID.indexOf("Nodes"));
