This article is about how html5 uses the amazeui tree node to automatically expand the panel and select the first tree node. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Amaze UI Tree is an extension of the Amaze framework, the advantage is that the style is consistent with the Amaze framework, the disadvantage is very imperfect, in order to be able to be applied in the project, its core code has been modified (another article published, will not repeat here). The function of the selected tree node in its API fails many times, so it simply rewrites one. As follows:

/ / expand the folding panel $("# user-nav"). Collapse ('open') by default; / / click the first button var btnArray = $(".am-tree-branch-name.click-item") by default; btnArray.each (function (I) {/ / console.log ($(this) .html () If (I = = 1) {$(this) .click (function () {$(".click-item") .removeClass ("am-tree-icon"); $(".click-item") .removeClass ("am-icon-check") $(this) .addClass ("am-tree-icon"); $(this) .addClass ("am-icon-check"); var obj = new Object () Obj.title = $(this) .attr ("data.title"); obj.level = $(this) .attr ("data.level") $(this) .trigger ('tree-click', {data: obj});}); $(this) .trigger (' click') Thank you for reading!
