I am important below Modal in each view that I am using to communicate unique view/page related errors or success messages to users:
<DynamicModal :title="titleModal" :description="descriptionModal" #functionDoSommething="myFunction" #open="open = !open">
</DynamicModal>
However, when I import the Modal in the Header/Navigation component I get a CallStack error as I already imported the Modal in the Parent view.
There is a lot of repetition as you can imagine as I am importing the Modal in each view. plus I am not able to use the Modal in the header/navigation component.
I am binding unique view/page related title and description to the Modal in each view. That’s why I am not able to place the Modal in App.vue
Anyone have a better way to use a dynamic Modal where I can bind title and description based on which view the Modal opens in?
Should I use Vuex?
I have an expandable listview on the parent screen. I expanded listview to see subcategory items. Now I clicked on one subcategory, it will navigate another screen(child screen). when I click on goback() method in child screen the parent screen is displaying with a collapsed list view.
Need to expand the expandable listview in expand mode only which are opened before in Parent screen when clicking on goback() in child screen.
Please help me.
I think you can use a parent screen name in the navigation to move from child to parent instead of goback().
Use navigation.replace(routeName,params) to pass the selected list in child componentÏ instead of goBack.
General question here not tied to a particular piece of code: I need to know the coordinates of an element in order to scroll down to it.
This element has a v-show condition and is hidden on page load, but user can click a button that will reveal the element (by satisfying the v-show condition).
Problem: if I immediately calculate the coordinates of the element when user clicks the button, I do NOT get the correct coordinates. I have to wait for a second or two with a setTimeout() to finally get the right coordinates.
Question: is there a way to make Vue do this as soon as possible, instead of making it wait some arbitrary length of time?
If you’re showing an element and then wanting to scroll to it, you could try using the nextTick callback:
// Set data that will show other element, i.e.
// this.showOtherElement = true;
// Use nextTick callback to scroll to element in the next tick
this.$nextTick().then(() => {
// Put code to scroll to element here
});
In my React-Native app, I have a ListView with each row being rendered by following "Solution 2". Inside my row, I have a couple of custom TouchableHighlight components. When I press the "Delete" button in my row, I'd like it to replace the entire row or all the button components in the row, with a Text component saying, "This item has been deleted".
Does anyone have any idea of how to accomplish this? I'm not sure how to link my child component's onPress method (Delete button) to the parent component (Row) and have the Row replace its content with a Text component.
I created this code snippet to reproduce what you have described: https://snack.expo.io/Bk9-6VNLW.
You can accomplish the UI change by mutating the state of your row component which will trigger the update of your component. And by reading the deleted state, you can decide what components to render whether is a set of <TouchableHighlight>' buttons or just a` component.
I have a tabpanel with 4 lists as child items. When each list is shown I want to load it's data. When I launch the app all 4 show events fire even though only the first tab is active. Is this how it's supposed to be? I could use activeitemchange of the tabpanel to populate the lists but I want to keep the code separate for each list. It doesn't make sense having the tabpanel control it's child items.
There's another event call 'painted' which fires whenever a component as actually shown to the user. I don't know what the difference between 'show' and 'painted' is but this seems to fix my problem.
