Updating an array element

[sitefinitysteve]

Whats the best way to update an array element?

My array list is massive (large objects) so if I clone it, change THAT array, then set the clone back, there's some noticable lag in the app.

How would I just update a array element, or like a single property OF that array element.

Hi Steve,

Please check this example as it demonstrates how to update single property of an array element: http://dojo.telerik.com/@valchev/OtIjI

Okay let me ask you this...

Given this in my template
                <span data-bind="attr: { class: getStatusClass }"><span data-bind="text: Status"></span></span>
                <span class="logcount" title="Encounters Logged"><span data-bind="text: LogCount"></span>

When I update "Status" on the item as you defined, the text updates okay, but the getStatusClass function isn't called.  I used to have it as <span class="status #: Status #" but that wasn't updating through the model change...so I moved it to a function.

What should I be doing here?

Hello Steve,

Could you please update the Dojo example that I provided below so it illustrates your exact case?
In this way I will be able to examine your exact implementation and assist you further.

Sure here: http://jsbin.com/famixo/2/

Why aren't the completed items turning green?

Hi Steve,

Issue occurs because dependent methods must use the get method to get field values. For more information please check this help article:

Here is a link to the updated example: http://jsbin.com/qiqexuroxa/1/edit

Please also note that the template should have a single root item.

Ah geez yeah, thanks

Hey, is there a way to do it right from the template so I don't have to have a function to return a single bound value?

[Alexander Valchev]

Hi Steve,

The getStatusClass method basically gets the "Status" value. You may bind the class directly to the "Status" field.
