动态加载100多个节点时Dynatree变慢 [英] Dynatree slow when dynamically loaded with 100+ nodes

问题描述

我如何加快速度?

我从JSON Web服务获得结果(快如闪电).使用

I get the results from JSON web service (lightning fast). Adding nodes to the tree using

类似

parentNode.addChild({
        key: key,
        title: value,
        addClass: cssClass
    });

不幸的是，包含100多个元素的树需要1.5分钟才能加载. 我很失望...难道不是要与那么多节点一起使用吗?除了切换到其他组件，我现在还能做些什么?

Unfortunately, a tree with 100+ elements takes 1.5 minutes to load. I am disappointed...is it not made to be used with that many nodes? Anything I can do at this point aside from switching to another component?

谢谢！

推荐答案

此基准测试表明加载速度非常快: http://wwwendt.de/tech/dynatree/doc/test-bench. html (尽管总有改进的余地...)

This benchmark shows that it is loads pretty fast: http://wwwendt.de/tech/dynatree/doc/test-bench.html (Theres always room for improvement though...)

您的问题可能是，您分别加载并添加了节点吗? 在这种情况下，树也被渲染 100次以上，并且 确实很慢.

Your problem might be, that you load and add the nodes seperately? In this case the tree is also rendered 100+ times, and that is slow indeed.

看看示例，看看如何通过一次调用来加载一批节点: http://wwwendt.de/tech/dynatree/doc/sample-lazy. html

Have a look at the sample, to see how load a batch of nodes with one call: http://wwwendt.de/tech/dynatree/doc/sample-lazy.html
