H5 Script: How to retrieve checking on the current standard field Attribute

unknown

Good Day Developers,

I have a snippets as follows and i gotten eror isReadOnly is not a function.

Please advise, 

-WRBANO is a standard field is currently can be Enabled/Disabled
-I wanted to skip populating value if the field is Disabled

Your advise and Assistance is much appreciated!

const TRDT = this.controller.GetValue('WWTRDT').replace(///g, "");
const REPN = this.controller.GetValue('WWREPN');
const BANO = TRDT + "-" + REPN;

const isWRBANOReadOnly = this.controller.isReadOnly('WRBANO'); // Check if WRBANO is read-only

// Only set the value of WRBANO if it is not read-only
if (!isWRBANOReadOnly) {
this.controller.SetValue('WRBANO', BANO);
}

Best Regards,

Retrieving Element and Checking Read-Only State in H5Script

In H5Script, you can use GetElement() to get a reference to a child element within the current panel and prop() to check its properties. This is useful for manipulating elements or checking their state during development.

When to Use GetElement()

Use GetElement() to retrieve a specific child element by its name relative to the current panel. It's helpful when you know the element's name and need to interact with it directly.

Code Example Breakdown:

JavaScript

<span class="hljs-keyword">let myElement = <span class="hljs-built_in">this.controller.GetElement(); <span class="hljs-comment">// Get the element
<span class="hljs-built_in">console.log(myElement); <span class="hljs-comment">// You can now use myElement for further actions

Using prop() for Read-Only Check

The code snippet const isWRBANOReadOnly = this.controller.GetElement("WRBANO").prop("readonly"); demonstrates how to check if a specific element (in this case, "WRBANO") has the readonly property set to true. This can be useful to determine if the element can be modified by the user (e.g., an input field).

In Conclusion

By combining GetElement() and prop(), you can effectively retrieve elements and check their properties within H5Script, allowing for greater control over your application's behavior. Remember that GetElement() targets child elements within the current panel's context.
