I would like to change the page showing in Vuetify (version 2) data-table to one (first page) when new data arrives from server. My understanding is that :pagesync could be used but I have not been able to figure out how to do this.
Can someone help?
Solved by watching incoming data, binding :options to v-data-table and changing the options object from watcher to include the desired page (in my case page:1) when data changed.

Go here (Chrome seems to work best for this example):
https://jsfiddle.net/gongzza/m67d8f4x/2/
Type a#b.com into the input. Notice how the error goes away. Now clear the input.
In the console, programmatically set the value of the email with:
$('[name=email]').value = 'a#b.com'
Notice how the input changes but the validation does not get refreshed.
My recommendation is that you should use Vue to manipulate the values of these things. The only reason I can imagine you're trying to use jQuery here is because you're doing it from outside the Vue app. Given that, you would be better served to do this:
$('#app').__vue__.email = 'a#b.com'
That way Vue will notice the change and do it's own event handling. I'm not sure there's a more "official" way to access the Vue data, but this is the way I've done it before.
I am building an application using React-Redux + React Router.
So, if user enters https://my-website.com/teams, I want to present him Teams page.
Lets suppose that my app consists of 2 components: Header and TeamsScreen.
I need to load user data to display Header.
I need to load user data & teams data to display TeamsScreen.
What is the right way to achieve it according to Best Practices?
What I have done so far:
1) Introduced a new component, lets name it AuthenticatedUser
render() {
if(!this.props.userData)
return (
<Loader/>
);
return (
<div>
<Header userData={this.props.userData}/>
<TeamsScreen userData={this.props.userData}/>
</div>
);
}
Which loads user data on componentDidMount.
If user data is null, it displays loader. If it's not null, it renders Header and TeamsScreen.
2) I give user data as property to Header. I give user data as property to TeamsScreen.
3) On componentDidMount in TeamsScreen I load teams data.
If teams data is null, I display loader for TeamsScreen. Otherwise I display TeamsScreen.
It seems working, but...In case of slow internet and/or slow database here is how it looks like:
1) There is a big loader for whole page while user data gets loaded.
2) As soon as it gets loaded, I display a header and loader gets moved a bit down till teams data is loaded and I can display TeamsScreen.
I have an uncomfortable feeling that I am doing something wrong.
Please correct me.
Thank you in advance!
Any hints / links to articles will be appreciated.
In this case you should use redux. All code related to fetch data from server will be in actions which which can first start spinner and in turn dispatch another action which will hide spinner and set your data once data returned from server.
I have a very big handsontable. I have dropdown columns defined, but, the values for the sources are retrieved with AJAX.
How can I set the "source" property of a "column" of type "dropdown" dynamically?
Regards!
You can, and should, use:
hotInstance.updateSettings({
columns: getNewColumns()
})
Where getNewColumns() would return an array of columns with the data and new source (or make the AJAX call from in here). That should do it!
Thank you for the answer ZekeDroid.
I was able to solve my issue.
First lets talk about a problem in the angular directive:
I am using the handsontable's angular directive. Two things happen: 1. If I associated the datarows attribute to a nested variale in the model, for example $scope.hot.data, then when I change the value of the model ( $scope.hot.data ) the grid ui is not refreshed. I am pretty sure this is an issue with the directive. Now: 2. Assume I use $scope.data and I update its value (this is the model right), then the grid ui is not refreshed either. I have to do something like hotInstance.updateSettings({data: newData}) as well.
I have to do both things; that is, update the model and call the update settings method. This is the only way I could get it work properly.
Note: if I do $scope.$apply() instead the updateSettings, I get an error in the console.
I am working on a Drupal project which is using the Editable fields module.
Using that module I'm exposing a dropdown list of text options. It works just great. You click on the list, select an option and the option is updated via Ajax.
My challenge is I'm trying to change the options programmatically via jQuery. Using the following code:
jQuery('select#edit-field-status-0-field-status-und').val(1);
... my browser console area is happy with the code but the Ajax update does not take place.
I tried:
jQuery('select#edit-field-status-0-field-status-und').val(1).change();
Again no errors but the Ajax event still did not execute.
$('#edit-field-status-0-field-status-und').val("1");
will do the trick, as the only reason it wouldn't work would be that you have your select values as strings instead of numbers.
Alternatively the following is more detailed:
$('#edit-field-status-0-field-status-und option').eq(1).prop('selected', true);
Also this is not an 'AJAX' function, it's simply Jquery updating the DOM for the particular element.
The code I was using as recreated below was correct:
jQuery('select#edit-field-status-0-field-status-und').val(1).change();
I found out the reason why it wasn't working was because the ID of the target element changed dynamically.
So when I first inspected and found edit-field-status-0-field-status-und, the same element would change IDs to something like edit-field-status-0-field-status-und--1.
That was throwing things off and gave the impression my code wasn't working.
Thanks to #gts for your input.
I am using Sencha ExtJs grid 4.2 . I am using a Expander plugins for my grid and try to load data under expanded region from Ajax. Right now I am using this code to show data on expanding.
plugins: [{
ptype: 'rowexpander',
rowBodyTpl: new Ext.XTemplate(
'<br><img height="31" width="32" src="../upload/patient/thumb/{patient_image}">',
' <p><b>{fname}, {lname}</b></p>',
'<br> {accordian_view}'
)
}],
Here you can see that data is pre populated, but my requirement is to load data on expanding. I am trying hard to find the event or process to do it. But still no luck. If anyone have any idea please share.
Thanks in Advance
You might check out the expandbody event on the RowExpander plugin: http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.grid.plugin.RowExpander-event-expandbody
This event passes not only the row's bound record, but also the expanded element, so you could:
Request data via Ext.Ajax.request({...})
Handle response
Add content to expanded row
One thing to keep in mind, however, is the async nature of this approach. That is, the row is going to expand immediately, regardless of how long the subsequent request takes to come back. So it would probably be a good idea to do something like this instead when handling the expandbody event:
Add "loading" text/icon/whatever into expanded row area
Make Ajax request
Handle response
Replace loading text/icon/whatever with the data returned from the Ajax request
It's likely someone has already done so, but you could also (and I would highly suggest it) wrap this process into a custom plugin of your own that extends the RowPlugin. That way you could use it elsewhere in your app for any grid. If you end up creating a custom plugin, please share it with the community!
EDIT: A quick Google revealed a number of custom plugins that do precisely this. For example: https://github.com/nickbretz/Ext.ux.AsyncRowExpander/blob/master/AsyncRowExpander.js
