我检查了这棵树中的四个节点，我想在textarea上显示。

“父节点，最初选择，自定义图标，最初打开，另一个节点”

如何获取所有已检查的节点文本？

试试这个：

function getAllSelectedNodesText(jsTree) {
   // this returns ids of all selected nodes
   var selectedNodes = jsTree.jstree("get_selected"); 

   var allText = [];

   // Go through all selected nodes to get text (jquery)
   $.each(selectedNodes, function (i, nodeId) {
       var node = jsTree.jstree("get_node", nodeId);
       allText.push(node.text); // Add text to array
   });

   return allText.join(); // This will join all entries with comma
}

您可以这样称呼它：

var allSelectedText = getAllSelectedNodesText($("#tree"));
