获取Treeitem的path属性

本文介绍了一种在ZK框架中获取Treeitem节点路径的方法,通过递归遍历节点并记录索引来实现。该方法使得能够通过路径快速定位到指定的Treeitem。

由于zk的tree没有获取节点path的api,于是实现下面这个函数来获取Treeitem节点的path


int[] getPath(Treeitem item) {
List<Integer> p = new ArrayList<Integer>();
while ((item instanceof Treeitem) && item.getLevel() >= 0) {
p.add(item.indexOf());
item = item.getParentItem();
}
int path[] = new int[p.size()];
for (int i = p.size() - 1; i >= 0; i--) {
path[p.size() - 1 - i] = p.get(i);
}
return path;
}


这样就能通过tree.renderItemByPath(path).setSelected(true)来打开指定的treeitem。
好的,我明白你的意思了,我的插件也是通过点击来获取文件中diff,但是这样会导致diff页面跳转到对应点击文件。所有是否有办法拿到对应文件的diff而不进行跳转呢 下面是插件异步处理方法 // 温和的异步点击获取diff(进一步避免页面跳动) async function gentleAsyncClickToLoadDiff(file, maxWaitMs = 8000) { console.log(`[温和异步点击] 开始温和异步点击获取文件 ${file.fileName} 的diff`); // 保存当前页面状态 const currentScrollPosition = window.scrollY; const currentActiveElement = document.activeElement; const currentSelection = window.getSelection().toString(); console.log(`[温和异步点击] 保存当前页面状态: scrollY=${currentScrollPosition}, activeElement=${currentActiveElement?.tagName}`); // 检查是否有匹配的diff(文件名必须完全匹配) const exactMatch = fileDiffMap[file.fileName]; if (exactMatch) { console.log(`[温和异步点击] 文件 ${file.fileName} 已有完全匹配的diff缓存`); return exactMatch; } // 检查是否有智能匹配的diff const availableFiles = Object.keys(fileDiffMap); const matchingDiffFile = availableFiles.find(availableFile => { if (availableFile === '__single__') return false; const pageFileName = file.fileName; const apiFileName = availableFile; const getFileName = (path) => path.split('/').pop().split('\\').pop();

return matches.some(match => match); }); if (matchingDiffFile) { console.log(`[温和异步点击] 文件 ${file.fileName} 找到智能匹配的diff: ${matchingDiffFile}`); return fileDiffMap[matchingDiffFile]; } // 清空之前的diff缓存,确保获取到当前文件的diff const previousDiffMap = { ...fileDiffMap };
