刷新HTML网站(显示进度)，而javascript不断添加新结果 [英] refresh HTML site (show progress) while javascript continually adds new results
问题描述
我使用javascript递归扫描文件系统以进行用户定义的搜索.到目前为止一切正常.在脚本到达搜索末尾之前，仅显示完整的结果.对于大型文件系统，这可能需要一些时间.
如何立即显示连续输出到HTML页面(即result.innerHTML = found)，以便用户可以跟踪进度.到目前为止，我仅发现提示"或警报"会导致脚本暂停，从而使窗口更新其中间内容.
必须有一种优雅的方法来避免用户交互！
欢迎任何想法，谢谢
I use javascript to scan the file system recursively for user defined search. All works fine so far. Only the complete results are not displayed before the script reaches the end of its search. With large file systems that can take some time.
How can I perform a continually output into the HTML page (i.e result.innerHTML=found) with an immediate display so that the user can follow the progression. Until now I have only found out that a "prompt" or "alert" causes the script to pause and thus the window to update its intermediate contents.
There must be an elegant method to avoid user interaction!
Any ideas welcomed, thanks
