• • If you pass empty values ​​of variables

    var initConfig = {};
    var cac = {};
    var variables = {};
    
    if ('{{userId}}' !== 'undefined') {
        initConfig['userId'] = '{{userId}}'
    }
    if ('{{email}}' !== 'undefined') {
        initConfig['email'] = '{{email}}'
    }
    if ('{{phoneNumber}}' !== 'undefined') {
        initConfig['phoneNumber'] = '{{phoneNumber}}'
    }
    if ('{{contactName}}' !== 'undefined') {
        initConfig['name'] = '{{contactName}}'
    }
    if ('{{sourceId}}' !== 'undefined') {
        initConfig['source'] = '{{sourceId}}'
    }
    if ('{{value}}' !== 'undefined') {
        cac['value'] = '{{value}}'
    }
    if ('{{currency}}' !== 'undefined') {
        cac['currency'] = '{{currency}}'
    }
    if ('{{stringVariableFromList}}' !== 'undefined') {
        variables['stringVariableFromList'] = '{{stringVariableFromList}}'
    }
    if ('{{dateVariableFromList}}' !== 'undefined') {
        variables['dateVariableFromList'] = '{{dateVariableFromList}}'
    }
    if ('{{newTestVariable}}' !== 'undefined') {
        variables['newTestVariable'] = '{{newTestVariable}}'
    }
    initConfig['cac'] = cac;
    initConfig['variables'] = variables;
    var sSmartSenderData = initConfig;
    

  • If you use symbol values ​​of variables

    if("{{stringVariableFromList}}"!=="false" && "{{stringVariableFromList}}"!=="undefined") {
       variables["stringVariableFromList"]="{{stringVariableFromList}}";
    }
    

    If you pass symbols in variables, your browser can pass them as “false”, in order to prevent variables from changing to false use the following example script.
