使用PrimeNG,我可以滚动到TreeNode:
在html中:
<p-tree #mytreeid id="mytree"></p-tree>
在Angular中:
@ViewChild("mytree") mytree: Tree;
// selection is the TreeNode you want to scroll into view
scrollToSelectionPrimeNgDataTree(selection, tree, elementIdName) {
if (tree.value !== null) {
let index = tree.value.indexOf(selection);
let ele = document.getElementById(elementIdName).querySelectorAll("p-treenode")[index];
ele.scrollIntoView();
//ele.focus();
}
}
问题:如何使TreeNode(即&#39;选择&#39;)集中注意力?我试图调用focus()方法,但focus()不是Element的方法。
答案 0 :(得分:0)
我找到了解决方案,我们只需要将[(选择)]设置为所选节点:
<p-tree #mytree id="mytree" [value]="componentGroups" selectionMode="single" [(selection)]="selectedNode">
