To solve this problem, we need to reformat a given JSON input into a structured HTML format that clearly presents system requirements. The JSON input can either be a single system requirement or multiple system requirements for different operating systems. The goal is to transform this input into a clean, user-friendly HTML format that follows specific structural guidelines.
### Approach
1. **Identify Input Structure**: Determine if the input JSON contains multiple systems (each with a "system" key) or a single system (without a "system" key).
2. **Handle Multiple Systems**: If the input contains multiple systems, each system's requirements are processed separately, converting HTML strings into individual list items.
3. **Handle Single System**: If the input is a single system, each key-value pair is processed to form the system requirements list.
4. **Construct HTML Structure**: For each system, create a div with a heading, a bold paragraph for "MINIMUM SPECS", and an unordered list where each requirement is listed with a span for the key.
5. **Parse HTML Strings**: If a requirement is given as an HTML string, parse it to extract key-value pairs and format them accordingly.
6. **Output HTML**: Construct the final HTML string following the specified structure, ensuring proper formatting and separation between multiple systems.
### Solution Code
```javascript
// Function to reformat the HTML based on the input structure
function reformatHTML jsonData {
let html = '';
const isMultiSystem = Object.keys(jsonData[0]).includes('system');
// Process multiple systems
if (isMultiSystem) {
for (const sys of jsonData) {
const system = sys.system;
const requirement = sys.requirement;
// Start the prod-spec div
html += `
`; } } else { // Process single system html += `
if multiple systems are present if (isMultiSystem && jsonData.length > 1) { html = html.replace(/(
)+$/, ''); } return html; } ``` ### Explanation The solution involves parsing the JSON input to determine if it contains multiple system requirements or a single one. For multiple systems, each requirement string is parsed to extract key-value pairs and formatted into HTML list items. For a single system, key-value pairs are directly converted into the required format. The solution ensures that the output is clean, well-structured HTML, adhering to the specified guidelines.
`;
html += `
`; html += `
`;
html += `${system} System Requirements
`; html += ``; html += `
MINIMUM SPECS
`; html += `- `;
// Parse the requirement HTML string
const parser = new DOMParser();
const doc = parser.parseFromString(requirement, 'text/html');
const listItems = doc.querySelectorAll('ul li');
for (const li of listItems) {
const strongEls = li.querySelectorAll('strong');
let key = '';
let value = '';
if (strongEls.length > 0) {
key = strongEls[0].textContent;
const textNodes = li.childNodes;
let remainingText = '';
let foundStrong = false;
for (const node of textNodes) {
if (node.nodeType === Node.TEXT_NODE && foundStrong) {
remainingText += node.textContent;
} else if (node.nodeType === Node.ELEMENT_NODE && node.nodeName === 'STRONG') {
foundStrong = true;
}
}
value = remainingText.trim();
}
html += `
- `; html += `${key} ${value}`; html += ` `; } html += `
`; } } else { // Process single system html += `
`;
html += `
`; html += `
`;
}
// Remove the last PC System Requirements
`; html += ``; html += `
MINIMUM SPECS
`; html += `- `;
const keyMappings = {
'OS': 'Operating System',
'Processor': 'Processor',
'Memory': 'Memory',
'Graphics': 'Graphics',
'Hard Drive': 'Hard Drive',
'Additional': 'Additional'
};
for (const req of jsonData) {
const key = Object.keys(req)[0];
const value = req[key];
const displayKey = key_mappings[key] || key;
html += `
- `; html += `${displayKey}: ${value}`; html += ` `; } html += `
if multiple systems are present if (isMultiSystem && jsonData.length > 1) { html = html.replace(/(
)+$/, ''); } return html; } ``` ### Explanation The solution involves parsing the JSON input to determine if it contains multiple system requirements or a single one. For multiple systems, each requirement string is parsed to extract key-value pairs and formatted into HTML list items. For a single system, key-value pairs are directly converted into the required format. The solution ensures that the output is clean, well-structured HTML, adhering to the specified guidelines.
