JS control ASP.NET's treeview control selects all or cancels (sample code)_javascript skills

Copy code The code is as follows: /* Function name: CheckNode(currentNode), ParentNode(currentNode), ChildNode(currentNode) Function: Implement treeview with checkbox 1. Select the parent node and all its child nodes will be selected 2. After canceling the selection of all child nodes, the selection of the parent node will also follow. Cancel

Usage: 1. Add CheckNode(currentNode), ParentNode(currentNode), ChildNode(currentNode) in the middle of

2. Add yourTreeView.Attribute.Add("OnCheck","CheckNode(yourTreeView.getTreeNode(yourTreeView.clickedNodeIndex))") in the Page_load() event of *.aspx.cs */

//Recursively traverse all child nodes function CheckNode(currentNode) { var childNode=new Array(); var parentNodeChild=new Array(); var isChecked; childNode=currentNode.getChildren(); if(currentNode.getAttribute('checked')) { isChecked=true; } else { isChecked=false; } //Parent node processing if(currentNode.getParent()!=null) { //Selected processing if(currentNode.getAttribute ('Checked')) { ParentNode(currentNode); } else //Uncheck { ChildNode(currentNode); } } else { //Do nothing } //Child node processing if(childNode.length>0) { for(var i=0;i { childNode.setAttribute("Checked",isChecked); if(childNode.getChildren().length>0) { CheckNode(childNode); } } }

} //Recursively select the parent node function ParentNode(currentNode) { if(currentNode.getParent()!=null) { currentNode.getParent().setAttribute('Checked',true); //Recursively call ParentNode(currentNode) to traverse updates The parent node of the previous layer ParentNode(currentNode.getParent()); } } //Recursively unselect the parent node function ChildNode(currentNode) { if(currentNode.getParent()!=null) { var checkedCount=0; var childNode=currentNode.getParent().getChildren(); for (var i=0; i { if(childNode.getAttribute('Checked')) { checkedCount ; } } if(checkedCount= =0) { currentNode.getParent().setAttribute('Checked',false); } //Recursively call ChildNode(currentNode) to traverse the higher-level parent node ChildNode (currentNode.getParent()); The problem

Copy code

The code is as follows: var AllRootNode=new Array(); AllRootNode=TreeView1.getChildren(); AlertNode(AllRootNode);
