Summary of common functions and features of infinite tree Jquery plug-in zTree_jquery

In fact, the Ztree official website already has detailed API documentation. Everything is subject to the instructions on the official website. I am just summarizing a few commonly used ztree functional features based on practice.

(The syntax structure of ztree is based on key-value configuration)

1: Support asynchronous loading of data

Syntax configuration:

async: {
enable: true, 

url:'abc.ashx',

otherParam: { "request": "requestname" }

}

Brief description:

enable: Set whether zTree enables asynchronous loading mode.

url: URL address for Ajax to obtain data.

otherParam: Static parameter key-value pair submitted by Ajax request. Equivalent to the data parameter in ajax.

2: Load data and bind . Generally, the data structure entity is defined as model. This data structure must contain hierarchical relationships and usually includes: ID, parent ID, Name.

Then configure the syntax:

data: {
simpleData: {
enable: true
}
}

or

data: {
key: {
children: "childrens",

checked: "IsChecked"
}
}

Brief description:

simpleData: You can use arrays as data source binding. At this time, the data loaded asynchronously can be a parallel structure.

children: Specify the attribute name to save the child node data in the node data. At this time, the data loaded asynchronously is the folded structure of the tree; so the recursive algorithm must be used when the backend loads data.

3: Support single selection and check function

Syntax configuration:

check: {
enable: true,
chkStyle: "checkbox",
radioType: "all"
chkboxType:{ "Y": "", "N": "" }
},

data: {
key: {

checked: "IsChecked"
}
}

Brief description:

enable: Set whether checkbox / radio is displayed on the zTree node

chkStyle: checkbox type (checkbox or radio)

radioType:radio grouping range

chkboxType: Check the checkbox for the relationship between parent and child nodes

checked: Indicates whether the check box is checked after loading data. IsChecked is a field defined in the back-end data structure model.

4: Support adding child nodes, editing nodes, and deleting node events

Here I will introduce how to customize adding, editing, and deleting buttons

Syntax configuration:

view: {
addHoverDom: addHoverDom,
removeHoverDom: removeHoverDom
　}

The addHoverDom function is:

function addHoverDom(treeId, treeNode) {
var sObj = $("#" + treeNode.tId + "_span");
if ($("#addBtn_" + treeNode.id).length > 0) return;
var str= "<a id='addBtn_" + treeNode.id + "' onclick='自定义函数1(" + treeNode.DepartmentID + ")'>添加子节点</a>";
str+= "<a id='addBtn1_" + treeNode.id + "' onclick='自定义函数2(" + treeNode.DepartmentID + ")'>编辑节点</a>";
str+= "<a id='addBtn2_" + treeNode.id + "' onclick='自定义函数3(" + treeNode.DepartmentID + ")'>删除节点</a>";
sObj.after(str);
};

The removeHoverDom function is:

function removeHoverDom(treeId, treeNode) {
$("#addBtn_" + treeNode.id).unbind().remove();
$("#addBtn1_" + treeNode.id).unbind().remove();
$("#addBtn2_" + treeNode.id).unbind().remove();
　};

Brief description:

addHoverDom: used to display user-defined controls when the mouse moves to a node. The hidden state is the same as the edit and delete buttons inside zTree

removeHoverDom: Used to hide user-defined controls when the mouse moves out of a node. The hidden state is the same as the edit and delete buttons inside zTree
