Understanding Client and User Event Scripts

Introduction

In Netsuite, client scripts and user event scripts are two types of scripts that can be used to extend the functionality of the platform. Client scripts are used to perform actions on the client-side, such as validating form data or refreshing the page, while user event scripts are used to perform actions on the server-side, such as creating custom buttons or sending emails. In this article, we will discuss how to pass parameters from a Netsuite client script to a user event script.

Understanding Client and User Event Scripts

Before we dive into the details of passing parameters between client and user event scripts, let's quickly understand what each type of script is used for.

Client Scripts

Client scripts are used to perform actions on the client-side, such as:

Validating form data
Refreshing the page
Showing or hiding fields
Performing calculations

Client scripts are executed on the client-side, which means they are executed on the user's browser. This makes them ideal for performing actions that require immediate feedback, such as refreshing the page or showing a message to the user.

User Event Scripts

User event scripts, on the other hand, are used to perform actions on the server-side, such as:

Creating custom buttons
Sending emails
Updating records
Performing complex calculations

User event scripts are executed on the server-side, which means they are executed on Netsuite's servers. This makes them ideal for performing actions that require access to the server-side data, such as updating records or sending emails.

Passing Parameters from Client Script to User Event Script

Now that we have a basic understanding of client and user event scripts, let's discuss how to pass parameters from a client script to a user event script.

Using the `nlapiGetURL` Function

One way to pass parameters from a client script to a user event script is by using the nlapiGetURL function. This function allows you to get the current URL of the page and append parameters to it.

Here is an example of how to use the nlapiGetURL function to pass a parameter from a client script to a user event script:

function clientScript() {
    var param = 'value';
    var url = nlapiGetURL('param', param);
    nlapiSetRedirectURL(url);
}

In this example, the clientScript function gets the current URL of the page and appends a parameter called param with a value of value. The nlapiSetRedirectURL function is then used to set the redirect URL to the new URL with the appended parameter.

Using the `nlapiCreateURL` Function

Another way to pass parameters from a client script to a user event script is by using the nlapiCreateURL function. This function allows you to create a new URL with parameters.

Here is an example of how to use the nlapiCreateURL function to pass a parameter from a client script to a user event script:

function clientScript() {
    var param = 'value';
    var url = nlapiCreateURL('param', param);
    nlapiSetRedirectURL(url);
}

In this example, the clientScript function creates a new URL with a parameter called param and a value of value. The nlapiSetRedirectURL function is then used to set the redirect URL to the new URL with the appended parameter.

Using the `nlapiGetRecord` Function

Another way to pass parameters from a client script to a user event script is by using the nlapiGetRecord function. This function allows you to get the current record and access its fields.

Here is an example of how to use the nlapiGetRecord function to pass a parameter from a client script to a user event script:

function clientScript() {
    var record = nlapiGetRecord('message');
    var param = record.getFieldValue('template');
    nlapiSetRedirectURL(nlapiCreateURL('param', param));
}

In this example, the clientScript function gets the current record and accesses its template field. The nlapiCreateURL function is then used to create a new URL with a parameter called param and a value of the template field value. The nlapiSetRedirectURL function is then used to set the redirect URL to the new URL with the appended parameter.

Conclusion

In this article, we discussed how to pass parameters from a Netsuite client script to a user event script. We covered three different methods for passing parameters, including using the nlapiGetURL function, the nlapiCreateURL function, and the nlapiGetRecord function. By using these methods, you can pass parameters from a client script to a user event script and perform actions on the server-side.

Example Use Case

Here is an example use case for passing parameters from a client script to a user event script:

Suppose you have a custom button on a Netsuite message record that you want to use to send an email to a customer. You can use a client script to get the selected template value and pass it to a user event script that sends the email.

Here is an example of how you can use the nlapiGetRecord function to pass the selected template value from a client script to a user event script:

function clientScript() {
    var record = nlapiGetRecord('message');
    var param = record.getFieldValue('template');
    nlapiSetRedirectURL(nlapiCreateURL('sendEmail', param));
}

In this example, the clientScript function gets the current record and accesses its template field. The nlapiCreateURL function is then used to create a new URL with a parameter called sendEmail and a value of the template field value. The nlapiSetRedirectURL function is then used to set the redirect URL to the new URL with the appended parameter.

The user event script can then use the param value to send the email to the customer.

Best Practices

Here are some best practices to keep in mind when passing parameters from a client script to a user event script:

Use the nlapiGetURL function to get the current URL of the page and append parameters to it.
Use the nlapiCreateURL function to create a new URL with parameters.
Use the nlapiGetRecord function to get the current record and access its fields.
Use the nlapiSetRedirectURL function to set the redirect URL to the new URL with the appended parameter.
Make sure to validate the parameters before passing them to the user event script.
Make sure to handle any errors that may occur when passing parameters from the client script to the user event script.

Introduction

In our previous article, we discussed how to pass parameters from a Netsuite client script to a user event script. In this article, we will answer some frequently asked questions (FAQs) related to passing parameters from client scripts to user event scripts.

Q: What is the difference between `nlapiGetURL` and `nlapiCreateURL`?

A: nlapiGetURL is used to get the current URL of the page and append parameters to it, while nlapiCreateURL is used to create a new URL with parameters. nlapiGetURL is useful when you want to append parameters to the current URL, while nlapiCreateURL is useful when you want to create a new URL with parameters.
