Hi,

The following function will transform all required field label with *

.

function tansformRequiredField(){
     var o = nuSERVERRESPONSE.objects;
                for (let i = 0; i < o.length; i++) {
                    let id = o[i].id;
                      if (o[i].valid == '1'|| o[i].valid == '3'){
                        
                         
                         $("#label_" +id).append('<span style="color:red;">*<span/>');
                         $("#label_" +id).attr('title',nuTranslate('Required field.'));
                      }

    
    
                }  
}

The function can be called in individual edit forms js or in the header for all forms.

Just sharing to the forum.

Hi Nilesh,

Thank you for sharing your code! This will certainly be a valuable addition to our Code Library.

To optimise this code, we can make a few improvement (mostly suggested by ChatGPT):

1. Caching jQuery Selectors: Repeatedly selecting the same element using jQuery can be expensive. Instead, we can cache the selected element for better performance.

2. Avoid Redundant DOM Manipulation: In the current code, you're selecting the same element twice (`$("#label_" +id)`) and appending the same content to it. This can be optimized to select the element once and then manipulate it.

3. Use Single Quotes for HTML Attributes: It's a good practice to use single quotes for HTML attributes to avoid potential conflicts with double quotes within the attribute content.

Here's the optimized version of your code:

Code: Select all

function tansformRequiredField() {
    var o = nuSERVERRESPONSE.objects;
    for (let i = 0; i < o.length; i++) {
        let id = o[i].id;
        if (o[i].valid === '1' || o[i].valid === '3') {
            let labelElement = $("#label_" + id);
            labelElement.append('<span style="color:red;">*</span>');
            labelElement.attr('title', nuTranslate('Required field.'));
        }
    }
}

However, I'd like to suggest using jQuery's `.each()` function to iterate through the array of objects. This can make the code more concise and readable:

Code: Select all

function tansformRequiredField() {
    const o = nuSERVERRESPONSE.objects;
    $.each(o, function(index, object) {
        if (object.valid === '1' || object.valid === '3') {
            $("#label_" + object.id).append('<span style="color:red;">*</span>')
                       .attr('title', nuTranslate('Required field.'));
        }
    });
}

Remember that optimizing code is not just about performance, but also about readability and maintainability. The optimized code versions aim to balance all these factors.

Thanks Kevin for the improved function and suggestions.

Appreciated and i will keep the in mind for future functions.

Hope NB users find the function useful.

To achieve this in pure CSS:

Code: Select all

.nuBlank::after,
.nuDuplicateOrBlank::after {
    content: "*";
    color: red;
    font-weight: bold;
    margin-left: 4px;
}

/* Optional: Remove bold style from labels */
.nuBlank,
.nuDuplicateOrBlank {
    font-weight: normal;
}

To add the "Required Field" title, you would probably still need JS. This is optional (The use of an asterisk (*) within HTML elements or labels as a convention is a well-established practice in web design. Users are generally familiar with its significance, making it unnecessary to explicitly explain its meaning in a title or separate text)

Code: Select all

const objects = nuSERVERRESPONSE.objects;
objects.forEach(object => {
    if (object.valid === '1' || object.valid === '3') {
        $(`#label_${object.id}`).attr('title', nuTranslate('Required field.'));
    }
});
