How to get value of a string after last slash in JavaScript?
The task is to get the string after a specific character(‘/’). Here are few of the mostly 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 1: This example using the approach discussed above.
<!DOCTYPE HTML><html> <head> <title> Get value of a string after last slash in JavaScript? </title></head> <body style="text-align:center;" id="body"> <h1 style="color:green;"> GeeksForGeeks </h1> <p id="GFG_UP" style="font-size: 15px; font-weight: bold;"> </p> <button onclick="GFG_FUN()"> click here </button> <p id="GFG_DOWN" style="font-size: 24px; font-weight: bold; color: green;"> </p> <script> var el_up = document.getElementById("GFG_UP"); var el_down = document.getElementById("GFG_DOWN"); var str = "folder_1/folder_2/file.html"; el_up.innerHTML = "Click on the button to get"+ " the string after last slash.<br><br>String - '" + str + "'"; function GFG_FUN() { str = str.split("/"); el_down.innerHTML = str[str.length - 1]; } </script></body> </html> |
Output:
- Before clicking on the button:
- After clicking on the button:
Approach 2:
- First, find the last index of (‘/’) using .lastIndexOf(str) method.
- Use the .substring() method to get the access the string after last slash.
