The task is to get the string after a specific character(‘/’). Here are a few of the most used techniques discussed. We are going to use JavaScript.
Approach 1:
- Split the string by .split() method and put it in a variable(array).
- Use the .length property to get the length of the array.
- From the array return the element at index = length-1.
Example: This example uses the approach discussed above.
Javascript
let str = "folder_1/folder_2/file.html";function GFG_FUN() { str = str.split("/"); console.log(str[str.length - 1]);}GFG_FUN(); |
Output
file.html
Approach 2:
- First, find the last index of (‘/’) using .lastIndexOf(str) method.
- Use the .substring() method to get access the string after the last slash.
Example: This example uses the approach discussed above.
Javascript
let str = "folder_1/folder_2/file.html";function GFG_FUN() { console.log(str.substring(str.lastIndexOf('/') + 1));}GFG_FUN(); |
Output
file.html
Approach 3:
- Split the string by .split() method
- pop the variable by using pop() method
Example: This example uses the above approach
Javascript
let str = "folder_1/folder_2/file.html";function GFG_FUN() { str = str.split("/").pop(); console.log(str);}GFG_FUN(); |
Output
file.html
