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;
