I have a Vue instance whose data contains an array of objects. I display this data in a table without issue.
Upon clicking the table rows, I set a "selected" property on the corresponding data object using:
key.$set('testing', testing);
Upon setting this value, I add a custom css class the the table row, without issue.
However, if I do a simple output of the entire array of objects at the bottom of the page (such as below), it doesn't get updated to reflect the new "testing" attribute I have added.
{{ gridData | json }}
I was able to reproduce my question using some modified vue.js example code in this JSFiddle:
https://jsfiddle.net/wdmatl/531axrtt/
Notice when you click on rows of data, you either see "testing" or "not testing". But this new object data isn't reflected in the json at the bottom of the page. Why not?

v-data-table component has a propery "expanded" that allows to show some additional info for each row.
It works fine and I need to expand all the rows immediately when a page is loaded.
Is there a way to do that?
It is used version 1.5 of Vuetify Framework.
https://v15.vuetifyjs.com/en/components/data-tables
This is fairly easy in the new Version of Vuetify, you just use the property expanded which holds an Array of the items that are currently expanded.
<v-data-table
id="issues-table"
:value="selectedIssues"
:expanded="expandedIssues"
:items="issues"
>
<v-switch #change="(v) => expandAllIssues(items, v)" />
expandAllIssues (items, status) {
if (status) {
this.expandedIssues = items
} else {
this.expandedIssues = []
}
}
In V1.5.xx of Vuetify you don't have that luxury, but when I took a look, Vuetify works with a similar system under the hood. Firstly you should set the expand prop on the table to true, so it can expand multiple rows.
You can define a reference on your data table and then access it via this.$refs.myDataTableRef. You then realise that they store the expanded rows in an Object called expanded. You can set the rows either true by the id/name of the row in this object or you simply set the whole row objects in the vuetify expanded object to true.
I have pasted the Codepen example of their old data table and made a simple expand all button, that you can obviously change to your desires, but it should make the concept clear.

I have a list of items. Each item has a "complete" flag. If this flag is true, the item shows in view A. If it is false, it shows in view B. The items are retrieved via an API request, with a client-side filter applied through a computed method on the base dataset. So for view A it will return items with complete=true, for view B, it will return items with complete=false.
The complete flag is editable (via a checkbox). I have a watcher function on the complete field that results in a PATCH being made to the item to toggle the complete field on the server.
Here's the issue. Since the vue app is filtering items based on the complete flag, any time that field changes, the item is removed from the view, so the watcher never gets triggered and the PATCH is never made.
It makes sense that the item's removal would cause the filter function to be re-run, however it seems odd that the watcher is killed before it can run.
So my question is, how do I achieve this - a list of filtered objects where the filter criteria can be changed, and have that change recognized via a watcher or similar?
You're probably better off using an #input event on the checkbox, and tying that to the api call:
<input type="checkbox" #input="onCheckChange">
...
methods: {
onCheckChange() {
// Perform API call here.
}
}
I have a scrollableView with several views inside and I'd like to add item to some of these view if they meet a certain criteria, like if they have data attached or not. Also I'm using Alloy, here's my markup
<ScrollableView id="scrollableView">
<View id="view" class='coolView'></View>
...
</ScrollableView>
To know if there are data attached I check the currentPage attribute like so:
function updateCurrentView(e) {
currentView = e.currentPage;
}
But I have no idea how to add an item to the current View.
Edit: To add some clarification, I have a label which when clicked allow me to choose two currencies, when chosen these currency pairs are saved in the database and should be displayed instead of the label. So my guess was to check whether the current view has currency pair saved.
There are 2 things to take care of here:
1.Whenever a currency is selected,immediately label on that particular view will change.
2.Whenever the scrollableView is loaded,it must always refer to the database if a currency is selected.
First one can be done as:
1.Get the instance of scrollableView using the getView method of alloy controller.Pass the id of the scrollableView to it.Lets call it myScrollableView.Refer this for more info.
http://docs.appcelerator.com/titanium/latest/#!/api/Alloy.Controller
2.Use var currentView=myScrollableView.getCurrentPage() to the get the current page which will be a number.
3.Now use the scrollableView instance to get all the views.
var viewArray=myScrollableView.getViews();
4.viewArray[currentView] will give you the view of current page.After you have got the view you can change the desired label using:
viewArray[currentView].children[positionOfTheView]
The "positionOfTheView" can be obtained by printing the viewArray[i].children array using Ti.API.info.
Second thing can be accomplished as follows:
1.Get the instance of scrollableView using the getView method of alloy controller.Pass the id of the scrollableView to it.Lets call it myScrollableView.Refer this for more info.
http://docs.appcelerator.com/titanium/latest/#!/api/Alloy.Controller
2.Now use the scrollableView instance to get all the views.
var viewArray=myScrollableView.getViews();
3.This is a JavaScript array of all the views in the scrollableView. Now iterate through this array and according to the data in the database,change the concerned view using:
viewArray[i].children[positionOfTheView]
The "positionOfTheView" can be obtained by printing the viewArray[i].children array using Ti.API.info.
I'm using boostrap library on Yii via yii-booster
I've created a relation table view
The related view is a TbGriView itself
Vhen in a row i click on the link on the 'related' column, the row expands itself, and render a TbGridview inside it.
The problem is that the internal gridview cannot be sorte, paged or filtered, because each action on it causes that the entire container grid will empty
Note
- external grid as a id of 'extenalgrid'
- each internal grid has as id like 'internalgrid-$rowId' , so every internal grid as differnt id on div, table and table row elements.
- the action called from "render related tabel" link is using renderPartial without the postProcess option. If i use potProcess, the row will be empty
So is it not possible to rendere a full working gridview/tbgridview into a related table ?
Use different css classes for the filters, buttons and headers for the different tables. From the jquery.yiigridview.js file events are bound to selectors as $('#table-id .selector-class') so elements in your internal gridView still trigger the events bound to the external gridView. You also have to specify a different url for the internal gridView by setting it's ajaxUrl.
I've scoured the dojo documentation, stack overflow, as well as thoroughly explored the EnhancedGrid object itself with firebug, and I'm not finding answers.
I have an enhanced grid that I populate with values for the user to sort on and basically create a selection set (using indirectSelection plugin). They then have a button to zoom to the selected items on a map.
The problem is, when sorting columns, it doesn't change the order of the items in the store itself, where I'm keeping an object inside each item that tells me how to zoom on the map, so I have no way to reconcile the grid.selection.selected array indices with the store._arrayOfAllItems indices.
edit: Note that I'm stuck using Dojo 1.6 as it's baked into the API I'm using.
Have a look at Dojo Object Store Tutorial.
You can set an idProperty to a Store, e.g.:
var employeeStore = new dojo.store.Memory({data:employees, idProperty: "name"});
Then you can operate the store with that id property using the get method like this:
// add a new employee
employeeStore.add({name:"George", department:"accounting"});
// remove Bill
employeeStore.remove("Bill");
// retrieve object with the name "Jim"
var jim = employeeStore.get("Jim");
Instead of using store._arrayOfAllItems. That way your grid.selection object will contain your id's values instead of array indexes (provided that your grid's store property is your store). This is the part that I'm guessing will work because I know for sure that the new dojo's dgrid does it that way, which I encourage you to use it BTW.
Hope it helps,
