| 1 | +JavaScript Project Assignment: Student Marksheet |
| 2 | + |
| 3 | +Objective: |
| 4 | + |
| 5 | +Create a Student Marksheet application using HTML, CSS, and JavaScript. The application should allow users to input student details, calculate total marks, percentage, and grade, and display the information in a tabular format. |
| 6 | + |
| 7 | +Requirements: |
| 8 | + 1. HTML Form: |
| 9 | + • Inputs for student details: |
| 10 | + • Student Name |
| 11 | + • Roll Number |
| 12 | + • Marks in three subjects (e.g., Math, Science, English) |
| 13 | + • A submit button to calculate and display results. |
| 14 | + 2. Table for Results: |
| 15 | + • Display: |
| 16 | + • Name |
| 17 | + • Roll Number |
| 18 | + • Marks for each subject |
| 19 | + • Total Marks |
| 20 | + • Percentage |
| 21 | + • Grade |
| 22 | + 3. JavaScript Functionality: |
| 23 | + • Calculate Total Marks, Percentage, and Grade: |
| 24 | + • Grade rules: |
| 25 | + • 90% and above: A+ |
| 26 | + • 80-89%: A |
| 27 | + • 70-79%: B |
| 28 | + • 60-69%: C |
| 29 | + • Below 60%: Fail |
| 30 | + • Validate inputs (e.g., no empty fields, marks should be numbers between 0 and 100). |
| 31 | + • Update the table dynamically with the calculated results. |
| 32 | + 4. Styling (Optional): |
| 33 | + • Use CSS to make the form and table visually appealing. |
| 34 | + |
| 35 | +Expected Output: |
| 36 | + |
| 37 | +A functional web page where users can enter student details, view their calculated results, and see a list of all students added so far. |
