QUESTION
I'm trying to solve an exercise in vanilla JS but can't figure out what I am doing wrong. I would like to change to color text to red if the product price is > 300.
In the console.log I'm getting all ok but on changeColor.style.color = "red"; I'm getting this error: TypeError: Cannot set property 'color' of undefined
Also because the page has a lazy load I could I get all price change by the time you are scrolling down?
Thanks
...ANSWER
Answered 2021-Jun-15 at 14:40 var offer = document.querySelectorAll(".grocery-item__normal-price");
var price = document.querySelectorAll(".grocery-item__normal-price");
let changePriceColor = 300;
price.forEach( (price) => {
var changeColor = price.innerHTML.slice(0,4).replace(/,/g, '');
if( changeColor > changePriceColor ) {
price.style.color = "red";
console.log(price, "true");
} else {
console.log(changeColor, "false")
}
})

QUESTION
When navigating from Composable A -> Composable B, say Composable A is a Lazy List scrolled halfway down and Composable B is a Lazy List Item Details Screen. Currently, the lazy list scroll position isn't stored, and when navigating back to Composable A from B, the list starts from item index 0. We could store it in a ViewModel, and read the value back, as well as use rememberSaveable, however, I am unsure as to how to implement rememberSaveable so that it scrolls to the saved position after back navigation.
Which method would be preferred to use following good code practices?
Edit: My problem arises from the fact that the listState isn't stored when navigating back from composable B to A. So if we scroll to the bottom and select an item and look at its details, when we navigate back to the list it is scrolled to the top, instead of saving its scrollState.
My composable
...ANSWER
Answered 2021-Jun-15 at 14:10I'm leaving this question up in case anyone else ever gets stuck in my situation, but the code works as it is meant to, I just committed a folly.
I didn't account for height changes with asynchronous image loading and as such, the list would not be at its saved position upon composable navigation, due to the list state being smaller than the screen height on returning to the composable.
However, If the images were given static containers to load into to that don't change their size, then upon back navigation, the composable would correctly display the saved list state.

Contract class:
...ANSWER
Answered 2021-Jun-14 at 11:51This is happening because there is no Transaction opened in DTO(object become detached). Wherever you have fetched the object from the DB call contractFile.getContract() so that the ORM framework loads the lazy-loaded object.

Install lazy
You can use lazy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
