Please Test This Html Form If You Find Any Problems Please Describe

Please test this HTML form. If you find any problems, please describe what each problem is and what the expected behavior would be. Instructions: The form is supposed to take an input string, find all instances of the "Find" string, and replace those instances with the "Replace" string. The tool also displays the input text and highlights the strings that were replaced in yellow. Ipnut: Find: Replace: Go Output:

This HTML form is designed to accept user input, find all instances of a specified string, replace them with another string, and display the processed text with replacements highlighted.

Output:

function escapeRegExp(string) {

// Escape special regex characters

return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');

}

function performReplace() {

const inputText = document.getElementById('inputText').value;

const findStr = document.getElementById('findString').value;

const replaceStr = document.getElementById('replaceString').value;

const outputDiv = document.getElementById('output');

if (findStr === '') {

// If find string is empty, display the input as-is

outputDiv.innerHTML = inputText;

return;

}

// Create a regex for all case-sensitive matches

const escapedFind = escapeRegExp(findStr);

const regex = new RegExp(escapedFind, 'g');

// Replace all instances with the replacement string

const replacedText = inputText.replace(regex, replaceStr);

// To highlight replacements, need to reconstruct the text with highlights

// We'll split the input text at each occurrence of the find string

const parts = inputText.split(regex);

let resultHTML = '';

for (let i = 0; i

resultHTML += parts[i];

if (i

// Add highlighted replacement

resultHTML += '' + replaceStr + '';

}

}

// To properly display the text with HTML entities and highlights

// Convert the original text to HTML-safe

function escapeHTML(str) {

return str.replace(/[&"']/g, function(match) {

const escapeMap = {

'&': '&',

'

'>': '>',

'"': '"',

"'": ''',

};

return escapeMap[match];

});

}

// Re-escape original parts to prevent HTML injection

// But since we're constructing the output at the same time, we can do:

let highlightedHTML = '';

// Construct final HTML with highlights in the replaced positions

highlightedHTML = '';

let currentIndex = 0;

let regexGlobal = new RegExp(escapedFind, 'g');

let match;

let lastIndex = 0;

while ((match = regexGlobal.exec(inputText)) !== null) {

// Add text before match

highlightedHTML += escapeHTML(inputText.substring(lastIndex, match.index));

// Add highlighted replacement

highlightedHTML += '' + escapeHTML(replaceStr) + '';

lastIndex = match.index + match[0].length;

}

// Add remaining text

highlightedHTML += escapeHTML(inputText.substring(lastIndex));

// For display, replace the input text with highlighted version

// But in order to keep the original text with highlighted replacements,

// Instead, we can do a safe substitution and display it

// To simplify, we reconstruct the output as the input text with replacements highlighted

// Better approach: generate a HTML string highlighting the replacements

// in the same positions as the replacements in the original text

let finalHTML = '';

let lastPos = 0;

// Use regex to find all find strings and replace with highlighted version

const pattern = new RegExp(escapeRegExp(findStr), 'g');

let matchPos;

let prevIndex = 0;

while ((matchPos = pattern.exec(inputText)) !== null) {

// add text before the match

finalHTML += escapeHTML(inputText.substring(prevIndex, matchPos.index));

// add highlighted replacement

finalHTML += '' + escapeHTML(replaceStr) + '';

prevIndex = matchPos.index + matchPos[0].length;

}

// add remaining text after last match

finalHTML += escapeHTML(inputText.substring(prevIndex));

// Display in output div

// For non-highlighted parts, add the text, and for replaced parts, add the highlight spans

// For simplicity, replace all find strings in inputText for output, highlighting replacements

// Replacing all occurrences in the display

const outputHTML = escapeHTML(inputText).replace(pattern, '' + escapeHTML(replaceStr) + '');

// Also, to avoid escaping the span tags, reconstruct the final output

// But since escapeHTML escapes everything, the replaced span tags won't be interpreted.

// To fix this, we'll build the output with the replacements directly.

// Here's a robust approach:

// Start with the entire escaped input

let safeOutput = escapeHTML(inputText);

// Replace all occurrences of findStr with the highlighted version

// Use a placeholder to avoid conflicts

const placeholder = '###REPLACE_HIGHLIGHT###';

// Escape findStr for regex

const findStrEscaped = escapeRegExp(findStr);

const findRegex = new RegExp(findStrEscaped, 'g');

// Replace all matches with placeholder

safeOutput = safeOutput.replace(findRegex, placeholder);

// Now, replace placeholder with highlighted version

const highlightedReplacement = '' + escapeHTML(replaceStr) + '';

// Final output: replace placeholders with highlighted replacements

const finalDisplayHTML = safeOutput.replace(new RegExp(escapeHTML(placeholder), 'g'), highlightedReplacement);

// Set the innerHTML of output div

outputDiv.innerHTML = finalDisplayHTML;
