如何在TypeScript中动态创建带单引号键的JSON Schema对象？

It sounds like your Schema Form Builder has a quirk where it expects object keys wrapped in single quotes instead of the standard JSON double quotes—even though technically JSON requires double quotes. Let’s walk through a few reliable ways to generate the format you need:

1. String Replacement (Quick Fix) #

If you’re already generating a valid JSON string (with double quotes), you can use a regex to replace only the key-enclosing double quotes with single quotes. This avoids messing up any double quotes that might be present in your values.

// Assume this is your dynamically generated JSON object
const formValueData = { 
  discountauthorizationelementsname: "userroleid,metalid,purityid,discountmodeid,categoryid,discounttypeid,discountvalue,creditpercent,creditvalue", 
  discountauthorizationelementstable: "discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization", 
  discountauthorizationelementscolmn:"userroleid,metalid,purityid,discountmodeid,categoryid,discounttypeid,discountvalue,creditpercent,creditvalue", 
  discountauthorizationelementspartabname: "discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization,discountauthorization", 
  discountauthorizationviewfieldids:"110", 
  viewfieldids:"110", 
  moduleid:"110", 
  discauthpassword:"21212121212" 
};

// Convert to JSON string, then replace key quotes
const singleQuotedString = JSON.stringify(formValueData)
  .replace(/"([^"]+)":/g, "'$1':") // Replace only key-enclosing quotes
  .replace(/:/g, ": ") // Optional: add space after colon for readability
  .replace(/,/g, ", "); // Optional: add space after commas

console.log(singleQuotedString);

2. Manual String Construction (More Control) #

If you want full control over the output format, build the string manually by iterating over your object’s key-value pairs. This lets you handle edge cases like single quotes in values (by escaping them) to avoid syntax errors.

function convertToSingleQuotedObj(obj) {
  return Object.entries(obj).map(([key, value]) => {
    // Escape single quotes in string values to prevent syntax breaks
    const processedValue = typeof value === 'string' 
      ? `'${value.replace(/'/g, "\\'")}'` 
      : value;
    return `'${key}': ${processedValue}`;
  }).join(', ');
}

// Generate the final formatted string
const singleQuotedResult = `{ ${convertToSingleQuotedObj(this.FormValueData)} }`;

3. Check for Tool Configuration (Long-Term Fix) #

Before resorting to string hacks, double-check if your Schema Form Builder has a setting to accept standard JSON (with double quotes). Many tools that claim to require single quotes actually support JSON natively—this quirk might just be a documentation oversight.

Important Note: #

If your values contain single quotes, make sure to escape them (as shown in the manual construction method) to avoid breaking the syntax of the generated string.
