Create client library

AEM Client Library manages all your client side JavaScript code. For this article, I have created a simple JavaScript to fetch the Adaptive Form data using the guide bridge API. Once the Adaptive Form data is fetched, the POST call is made to the servlet to either insert or update the adaptive form data in the database. The function getALLUrlParams returns the parameters in the URL. If the guid parameter is present in the URL, then we need to perform the update operation, if not it is an insert operation.The rest of the functionality is handled in the code associated with the click event of .savebutton class.

NOTE
The client library is provided as part of this tutorial assets
function getAllUrlParams(url) {

    // get query string from url (optional) or window
    var queryString = url ? url.split('?')[1] : window.location.search.slice(1);

    // we'll store the parameters here
    var obj = {};

    // if query string exists
    if (queryString) {

        // stuff after # is not part of query string, so get rid of it
        queryString = queryString.split('#')[0];

        // split our query string into its component parts
        var arr = queryString.split('&');

        for (var i = 0; i < arr.length; i++) {
            // separate the keys and the values
            var a = arr[i].split('=');

            // set parameter name and value (use 'true' if empty)
            var paramName = a[0];
            var paramValue = typeof(a[1]) === 'undefined' ? true : a[1];

            // (optional) keep case consistent
            paramName = paramName.toLowerCase();
            if (typeof paramValue === 'string') paramValue = paramValue.toLowerCase();

            // if the paramName ends with square brackets, e.g. colors[] or colors[2]
            if (paramName.match(/\[(\d+)?\]$/)) {

                // create key if it doesn't exist
                var key = paramName.replace(/\[(\d+)?\]/, '');
                if (!obj[key]) obj[key] = [];

                // if it's an indexed array e.g. colors[2]
                if (paramName.match(/\[\d+\]$/)) {
                    // get the index value and add the entry at the appropriate position
                    var index = /\[(\d+)\]/.exec(paramName)[1];
                    obj[key][index] = paramValue;
                } else {
                    // otherwise add the value to the end of the array
                    obj[key].push(paramValue);
                }
            } else {
                // we're dealing with a string
                if (!obj[paramName]) {
                    // if it doesn't exist, create property
                    obj[paramName] = paramValue;
                } else if (obj[paramName] && typeof obj[paramName] === 'string') {
                    // if property does exist and it's a string, convert it to an array
                    obj[paramName] = [obj[paramName]];
                    obj[paramName].push(paramValue);
                } else {
                    // otherwise add the property
