How to use GlideScriptEvaluator to remove eval() method from the existing scripts?

[nirwan_ritik]

1st Script:
        var response1 = r.execute();

        var responseBody1 = response1.getBody();

        var httpStatus1 = response1.getStatusCode();

        var ans = (JSON) ? JSON.parse(responseBody1) : eval(responseBody1);

        for (var i = 0; i < ans.length; i++) {

            if (ans[i].usr_username == userID) {

                str[j] = ans[i].app_pro_title.replace(/_|\-/, " ") + '-' + ans[i].app_number;

                j++;

            }

         }

2nd Script:

                var par = [];

                for (var i=levelValue; i < gr.getValue("hierarchy_level"); i++) {

                    par.push(relationalColumn);

                }

                eval("var p = gr."+par.join("."));

how to remove these eval() executions and replace them with GlideScriptEvaluator. 

 Kindly help me regarding this 🙂

Hi @nirwan_ritik ,

Creating an object for GlideScriptEvaluator you can use as below mentioned

var response1 = r.execute();
var responseBody1 = response1.getBody();
var httpStatus1 = response1.getStatusCode();
var scriptEvaluator = new GlideScriptEvaluator();
var ans = (JSON) ? JSON.parse(responseBody1) : scriptEvaluator.evaluateString(responseBody1);
for (var i = 0; i < ans.length; i++) {
    if (ans[i].usr_username == userID) {
        str[j] = ans[i].app_pro_title.replace(/_|\-/, " ") + '-' + ans[i].app_number;
        j++;
    }
}

var par = [];
for (var i = levelValue; i < gr.getValue("hierarchy_level"); i++) {
    par.push(relationalColumn);
}
var scriptEvaluator = new GlideScriptEvaluator();
var script = "var p = gr." + par.join(".");
scriptEvaluator.evaluateString(script);
