JavaScript Error Cannot read properties of null (reading 'getOptions')

(0) ShareShare

Posted on by akellcla93 30

I currently have a list of options in a choice that is very long. User wants to consolidate the list, but removing values from the option set in the table isn't an option. I'm attempting to hide certain options, but am running into the error "Cannot read properties of null (reading 'getOptions')" when the form loads. The option set is all lowercase and is spelled correctly, but I replaced it with "my_optionset". 

Here is my code: 

function hide_options(executionContext) {
// get form context
var formContext = executionContext.getFormContext();

// Get options from lead source. 
var optionValues = formContext.getControl('my_optionset').getOptions();

// Remove options from optionValues if not "Bid Notification System", "Contract Renewal", "Direct Sale", or "Marketing Generated"
for (let i = 0; i < optionValues.size; i++) {
if (optionValues[i] == "Bid Notification System" || optionValues[i] == "Contract Renewal" || optionValues[i] == "Direct Sale" || optionValues[i] == "Marketing Generated" || optionValues[i] == null) {
continue;
}
else {
formContext.getControl('ena_leadsource').removeOption(optionValues[i]);
}
}
}

    Fixed it with a complete rework:

    function hide_options(executionContext) {

     // get form context

     var formContext = executionContext.getFormContext();

     // Get options from lead source

     var option = formContext.getControl('my_optionset');

     var optionValues = option.getAttribute().getOptions();

     // Clear option and get ready to add other options back

     option.clearOptions();

     // Add correct Bid Notification System, Contract Renewal, Direct Sale, and Marketing Generated back to option set, remove all others

     optionValues.forEach(function (opt) {

       if(opt.value == "1111111111" || opt.value == "1111111111" || opt.value == "111111111" || opt.value == "1111111111") {

         option.addOption(opt);

       }

       else {

         option.removeOption(opt);

       }

     });

    }

    JavaScript Error Cannot read properties of null (reading 'getOptions')

    Want to preface this with I am newer to CRM administration, and this is my first time attempting to deploy a web resource. I currently have a list of options in a choice that is very long. User wants to consolidate the list, but removing values from the option set in the table isn't an option. I'm attempting to hide certain options, but am running into the error "Cannot read properties of null (reading 'getOptions')" when the form loads. The option set is all lowercase and is spelled correctly, but I replaced it with "my_optionset". 

    Here is my code: 

    function hide_options(executionContext) {
    // get form context
    var formContext = executionContext.getFormContext();

    // Get options from lead source. 
    var optionValues = formContext.getControl('my_optionset').getOptions();

    // Remove options from optionValues if not "Bid Notification System", "Contract Renewal", "Direct Sale", or "Marketing Generated"
    for (let i = 0; i < optionValues.size; i++) {
    if (optionValues[i] == "Bid Notification System" || optionValues[i] == "Contract Renewal" || optionValues[i] == "Direct Sale" || optionValues[i] == "Marketing Generated" || optionValues[i] == null) {
    continue;
    }
    else {
    formContext.getControl('ena_leadsource').removeOption(optionValues[i]);
    }
    }
    }
