How do I get the value before a certain value from a URL using jquery?

Question

For Example:

www.site.com/potato/hello/eweb/TestPage.aspx
// or
www.site.com/potato/eweb/TestPage.aspx

I want to get everything before eweb from the URL using jQuery no matter how long the url before eweb is.

So from the example #1 above, I want to get www.site.com/potato/hello/ back and www.site.com/potato/ for example #2 as my result.

Answer 1

您可以通过eweb split()当前URL并获取结果数组的第一个元素：

var baseUrl = window.location.href.split('eweb')[0]; 

Answer 2

Try using String.prototype.match() with RegExp /.*(?=eweb)/ to match any characters followed by "eweb"

 var str = "www.site.com/potato/hello/eweb/TestPage.aspx"; var res = str.match(/.*(?=eweb)/)[0]; console.log(res)
