First, Combotree gets the parent node method GetParent, which is actually inherited from the tree plugin

JS Code

1. Name Parameter Description
2. GetParent Target Get The parent node,
3. The target parameter indicate the node DOM object.

Tree gets the parent node:

JS Code

1. $ ("#treeId"). Tree ("getParent", node.target);

Combotree Get parent node:

Java code

1. var treeobj = $ ("#combotreeId"). Combotree ("tree"); Get the Combotree Tree object first
2. var parentnode = Treeobj.tree ("GetParent", node.target);

Second, Combotree gets the selected value

Java code

1. var treeobj = $ ("#combotreeId"). Combotree ("tree"); Get the Combotree Tree object first
2. var nodeschecked = Treeobj.tree ("getchecked"); The tree object gets all the selected values of the tree, and there may be multiple

Third, expand parent node

JS Code

1. $ ("#treeId"). Tree ("expand", Node.target); node is usually the parent

Iv. Expand all parent nodes based on the values selected by the leaf node

Expand methods for all parent nodes (recursively expand parent node):

JS Code

2. /**
4. * Expand all parent nodes according to leaf node
6. * @param treeobj Tree object, (Combotree tree object gets: var treeobj = comboobj.combotree ("tree");)
8. * @param node leaf nodes
10. */
12. function expandparent (treeobj, node) {
14. var parentnode = Treeobj.tree ("GetParent", node.target);
16. if (parentnode! = null && parentnode! = "undefined") {
18. Treeobj.tree ("expand", Parentnode.target);
20. Expandparent (Treeobj, parentnode);
22. }
24. };

The specific use is as follows:

JS Code

2. $ ("#cmm_code_id"). Combotree ({
4. Multiple: true,
6. Required: true,
8. CheckBox: True,
10. Onlyleafcheck: True,//Only leaf nodes can be checked
12. URL: "${pagecontext.request.contextpath}/xxx",
14. Onbeforeselect: function (node) {
16. $ (this). Tree ("Check", node.target); Control the click of text can also be checked
18. return false;
20. },
22. Onbeforecheck: Function (node, checked) {
24. if (checked) {//If it is a tick, clear the previously selected node (not checked)
26. var nodes = $ (this). Tree ("getchecked");
28. if (nodes.length > 0) {
30. For (var i=0; i<nodes.length; i++) {
32. $ (this). Tree ("uncheck", Nodes[i].target);
34. }
36. }
38. }
40. },
42. Onloadsuccess: function (node, data) {
44. var cmm_code_id_value = "${buildingnaming.cmm_code_id}";
46. if (cmm_code_id_value! = null && $.trim (cmm_code_id_value)! = "") {
48. var comboobj = $ ("#cmm_code_id");
50. var treeobj = Comboobj.combotree ("tree");
54. Comboobj.combotree ("SetValue", Cmm_code_id_value);
56. var nodeschecked = Treeobj.tree ("getchecked");
58. if (nodeschecked.length > 0) {
60. For (var i=0; i<nodeschecked.length; i++) {
62. Expandparent (Treeobj, nodeschecked[i]);
64. }
66. }
68. }
70. }
72. });
