javascript：从长网址获取十六进制

Question

For example i have such urls:

https://portalvhdsk7w6i7k9.blob.core.windows.net:443/project/5633cc12da73d9160c4cf146.dat
https://portalvhdsk7w6i7k9.blob.core.windows.com/project/5633cc12da73d9160c4cf146.dat
https://example.com/project/5633cc12da73d9160c4cf146.dat

can i somehow get only 5633cc12da73d9160c4cf146 using only js? is it possible?

Answer 1

You can split the string by / and the pop() the final element. Try this:

var url = 'https://portalvhdsk7w6i7k9.blob.core.windows.net:443/project/5633cc12da73d9160c4cf146.dat'
var hex = url.split('/').pop().replace('.dat', ''); // = '5633cc12da73d9160c4cf146'

If you want to get the location of the current page, use document.location .

Check this:

 var url = "https://portalvhdsk7w6i7k9.blob.core.windows.net:443/project/5633cc12da73d9160c4cf146.dat" var indexofProd = url.indexOf("project/"); indexofProd = indexofProd + 8; var indexofdotDat = url.indexOf(".dat"); var number = url.substring(indexofProd,indexofdotDat); alert(number);
