Is there any easy way to parse a query string from an URL with JQL since URLSearchParams can't be used?

Yes, there is an easy way to parse a query string from a URL in Mixpanel's JQL (JavaScript Query Language) without using URLSearchParams. Mixpanel provides a built-in function called getQueryParam() that can be used for this purpose.Here's an example of how you can use the getQueryParam() function in JQL: LBKSfunction getQueryParam(url, param) { // Expects a raw URL param = param.replace(/[[]/, "\[").replace(/[]]/, "\]");LBKS var regexS = "[\?&]" + param + "=([^&#]*)", regex = new RegExp( regexS ), results = regex.exec(url);LBKS if (results === null || (results && typeof(results[1]) !== 'string' && results[1].length)) { return ''; } else { return decodeURIComponent(results[1]).replace(/\W/gi, ' '); } };LBKSThis function is provided in the Mixpanel documentation for parsing UTM parameters, but it can be used to parse any query parameter from a URL Traffic Attribution: Analyze your marketing channels.You can use this function in your JQL queries to extract specific parameters from URLs. For example, if you want to get the value of a 'utm_source' parameter from a URL, you could do: LBKSvar url = "[https://example.com?utm_source=google&utm_medium=cpc](https://example.com?utm_source=google&utm_medium=cpc)"; var utm_source = getQueryParam(url, "utm_source");LBKSThis approach provides an easy and reliable way to parse query strings in JQL without relying on URLSearchParams.
