How to obtain the values of jump related variables such as window.location.href?

[chushuai]

I wrote a crawler. In order to crawl to the jumps in js, I used regular expressions to extract the jump information in js. However, this matching method cannot obtain complex js jumps, so I want to improve it through js semantic recognition. Accuracy

Below is my regex：

location\s*?=\s*?["'](.*?)["']
window.location\s*?=\s*?["'](.*?)["']
window.location.href\s*?=\s*?["'](.*?)["']
self\.location.*?=\s*?["'](.*?)["\']
top\.location.*?=\s*?["'](.*?)["\']
location\.replace\(["'](.*)["']\)
location\.assign\(["'](.*)["']\)
window.open\(["'](.*?)["']

For the following piece of JS code, it is obvious that the jump cannot be extracted through regular expressions：

<script>window.onload=function(){ url ='/webui';window.location.href=url;}</script>
