How to Iterate and Display Data from Multiple Arrays Simultaneously in Go Templates?

Combine Arrays for Iterated Display in Go Templates

The provided code requires displaying data from a collection of two Go structs (Schedule and Combo) in an HTML template. The requirement is to iterate over the Combo struct and simultaneously extract values from the arrays within that struct (i.e., Sounds, Volumes, and Waits) for separate display within the HTML table.

In Go templates, you can achieve this by accessing elements of arrays using the index function. This function takes the array as the first argument and the index of the element as the second argument. For instance, if $volumes is your array of volumes, you can access the volume at index 0 using {{index $volumes 0}}.

Here's an updated code snippet that incorporates this approach:

{{ $volumes := .Volumes }}
{{ $waits := .Waits }}
{{range $index,$sound := .Sounds }}

Print Sounds[i] like this: {{$sound}}

Print volumes[i] like this: {{index $volumes $index}}

Print waits[i] like this: {{index $waits $index}}

{{end}}

This code first assigns the elements of Volumes and Waits arrays to $volumes and $waits respectively. Then, it iterates over the elements of Sounds using $index and $sound as loop variables. Within the loop, you can access the corresponding values for volumes using {{index $volumes $index}} and for waits using {{index $waits $index}}. By combining this loop with the appropriate HTML elements, you can output a table with the desired format.

This solution eliminates the need to create additional data structures or modify the existing ones. It allows you to work with the provided data structures directly and achieve the desired presentation in your HTML template.
