I have an array of JSON data like :
loggers = [{
"allAvailableLevel": ['WARN', 'DEBUG', 'INFO'],
"level": "WARN",
"logger": "com.test1",
"status": "success"
},
{
"allAvailableLevel": ['WARN', 'DEBUG', 'INFO'],
"level": "WARN",
"logger": "com.test2",
"status": "success"
}
]
I am using dropdown inside a table column and for that using below code, and basically traversing Loggers array but not able to extract allAvailableLevel data.
<table class="table table-bordered">
<thead>
<tr>
<th>#</th>
<th>Class</th>
<th>Current Level</th>
<th>All Available Levels</th>
<!-- Only display "Action" header if level is changed-->
<th>
Action
</th>
</tr>
</thead>
<tbody>
<tr v-for="(logger, index) in loggers" :key="logger">
<td>{{ index + 1 }}</td>
<td>{{ logger.logger }}</td>
<td>{{ logger.level }}</td>
<td>
<b-dropdown
boundary="viewport"
id="dropdown-dropup"
size="sm"
:text="selectedLevelText"
split
class="m-2"
>
<b-dropdown-item-button
v-for="logger in loggers[0].allLevel"
:key="logger"
#click.prevent="changeLevel(level)"
>{{ logger }}</b-dropdown-item-button
>
</b-dropdown>
</td>
<td v-if="levelChanged">
<b-button
size="sm"
variant="secondary "
#click.prevent="updateLevel(selectedLevelText)"
>Update</b-button
>
</td>
</tr>
</tbody>
</table>
with above code my dropdown looks like :
I want to display it like this :
How do I traverse my data inside the vue template to get only the data of "allAvailableLevel"?
You should iterate over that nested array as follows :
<b-dropdown-item-button
v-for="level in logger.allAvailableLevel"
:key="level"
#click.prevent="changeLevel(level)"
>{{ level }}</b-dropdown-item-button
>
Do this:
<tr v-for="(logger, index) in loggers" :key="logger">
<td>{{ index + 1 }}</td>
...
<td>
<b-dropdown
boundary="viewport"
id="dropdown-dropup"
size="sm"
:text="selectedLevelText"
split
class="m-2"
>
<b-dropdown-item-button
v-for="level in logger.allAvailableLevel"
:key="level"
#click.stop="changeLevel(level)"
>{{ logger }}</b-dropdown-item-button
>
</b-dropdown>
</td>
</tr>

Currently, I am developing a site that guides coin market arbitrage information.
I wonder if the way below is possible in JavaScript.(not React)
backend - django
def index(request):
data = [{"name": "BTC", "binance": "price1", "gecko": "price2", "ftx": "price3"},
{"name": "ETH", "binance": "price1", "gecko": "price2", "ftx": "price3"}]
return render(request, 'index.html', context={'data': data})
html -
<table class="table table-striped mb-0 fixed">
<thead>
<tr>
<th>name</th>
<th>binance</th>
<th>gecko</th>
<th>ftx</th>
</tr>
</thead>
<tbody>
{% for d in data %}
<tr>
<td>{{ d.name }}</td>
<td>{{ d.binance }}</td>
<td>{{ d.ftx }}</td>
<td>{{ d.okx }}</td>
</tr>
{% endfor %}
</tbody>
</table>
JS -
var socket = new WebSocket(
'ws://' + window.location.host +
'/ws?session_key=${sessionKey}')
socket.onmessage = function (e) {
let positions_data = JSON.parse(e.data)
//if positions_data {"site": "binance", "price": "27000", "name": "BTC"}
//update data ->
data = [{"name": "BTC", "binance": "27000", "gecko": "price2", "ftx": "price3"},
{"name": "ETH", "binance": "price1", "gecko": "price2", "ftx": "price3"}]
//do something?
//then change html value
}
Is it possible to change the html value just by changing the variable in JS
Or is it possible to take additional code? Or is there another way?
Change your HTML so that the rows have a unique ID based on the coin name, and the columns have classes that indicate their roles.
<table class="table table-striped mb-0 fixed">
<thead>
<tr>
<th>name</th>
<th>binance</th>
<th>gecko</th>
<th>ftx</th>
</tr>
</thead>
<tbody>
{% for d in data %}
<tr id="row-{{d.name}}">
<td class="name">{{ d.name }}</td>
<td class="binance">{{ d.binance }}</td>
<td class="ftx">{{ d.ftx }}</td>
<td class="okx">{{ d.okx }}</td>
</tr>
{% endfor %}
</tbody>
</table>
Then you can find the row that corresponds to positions_data and update it:
let row = document.querySelector(`#row-${positions_data.name}`);
let site = positions_data.site;
row.querySelector(`.${site}`).innerText = positions_data.price;
I have a list of values [1, paracetamol,[{1, location, quantity}, {2, location2, quantity}]
so I have to print in two rows
1. [1, paracetamol, location, quantity]
2. [2. paracetamol, location1, quantity2]
I have maintained head
headElements = ['Drug ID', 'Drug Name', 'Location', 'Quantity']
<table class="table table-striped" >
<thead>
<tr>
<th *ngFor="let head of headElements" scope="col">{{ head }}</th>
</tr>
</thead>
<tbody>
<div *ngFor = "let drugDetail of drugList">
<tr *ngFor="let loc of drugDetail.drugLocationList">
<th scope="row">{{ drugDetail.drugId }}</th>
<td>{{ drugDetail.drugName }}</td>
<td>{{loc.location}}</td>
<td>{{ loc.quantity}}</td>
</tr>
</div>
</table>
output:
['Drug ID', 'Drug Name', 'Location', 'Quantity']
[1, paracetamol, location, quantity]
[2. paracetamol, location1, quantity2]
Maybe it could be easier if you do first a map to your array data, something like this:
copyDrugList = drugList.map(drugDetail => [
{ drugId : drugDetail.drugLocationList[0].drugId ,
drugName : drugDetail.drugName ,
location : drugDetail.drugLocationList[0].location ,
quantity : drugDetail.drugLocationList[0].quantity ,
},
{ drugId : drugDetail.drugLocationList[0].drugId ,
drugName : drugDetail.drugName ,
location : drugDetail.drugLocationList[1].location ,
quantity : drugDetail.drugLocationList[1].quantity ,
},
]);
Then, you only need to do a classic Angular HTML ngFor:
<tr *ngFor = "let drugDetail of copyDrugList ">
<td>{{ drugDetail.drugId }}</td>
<td>{{ drugDetail.drugName }}</td>
<td>{{ drugDetail.location }}</td>
<td>{{ drugDetail.quantity }}</td>
</tr>
We have Vue.js project with custom table bound to array. It looks as following:
The key part of HTML code looks as following:
<InfiniteScroll ref="scroller" :disable="finished" #load="onLoad">
<swipeable-table
v-if="waitingList.length"
:headers="headers"
:items="waitingList"
:loading="loading"
custom-width
outerBorder
>
<template slot="rows" slot-scope="{ item: booking }">
<tr>
<td>{{ 0 }}</td>
<td></td>
<td></td>
<td>{{ fullName(booking.user) }}</td>
<td>{{ unitName(booking.search_by) }}</td>
...
</tr>
</template>
</swipeable-table>
...
</InfiniteScroll>
The waitingList is an array of objects.
The part of JavaScript code looks as following:
methods: {
fullName(user) {
return fullName.by(user, null, true)
},
unitName(unit) {
return unit?.name ?? ''
},
...
The table is scrollable that is it shows 30 items at the beginning and after you scroll next 30 items (30+30=60) and so on.
The array of objects looks as following:
Is there any way to use some JavaScript method to achieve it? If not how can I do it?
you can add index in the same way as item in template.
<template slot="rows" slot-scope="{ item: booking,index:index }">
<tr>
<td>{{ index }}</td>
<td></td>
<td></td>
<td>{{ fullName(booking.user) }}</td>
<td>{{ unitName(booking.search_by) }}</td>
...
</tr>
</template>
I have a table like this that displays data including several navigation properties :
<table class="table afcstandings">
<thead>
<tr>
<th>team</th>
<th>coach</th>
<th>w</th>
<th>l</th>
<th>t</th>
<th>fa</th>
<th>agst</th>
<th>diff</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let standing of standingsAFCEast">
<!-- property binding rather than interpolation-->
<td>{{ standing.team.teamName }}</td>
<td>{{ standing.team.coach.coachName }}</td>
<td>{{ standing.won }}</td>
<td>{{ standing.lost }}</td>
<td>{{ standing.tied }}</td>
<td>{{ standing.pointsFor }}</td>
<td>{{ standing.pointsAgainst }}</td>
<td>{{ standing.pointsDifference }}</td>
</tr>
</tbody>
</table>
Here is the data structure that is being read :
[{"team":{"teamId":22,"teamName":"Carolina Panthers","coach":{"coachId":61,"coachName":"J Smith"},"division":{"divisionId":2,"divisionName":"NFC West"},"headerImage":"","logoImage":"","hex":"","r":null,"g":null,"b":null},"won":2,"lost":1,"tied":0,"pointsFor":82,"pointsAgainst":62,"pointsDifference":20}]
My question is, how do I display this data using ngx-datatable? I have tested with 3 fields, teamName, coachName and won, and am able to display the won field, but not the others, as I am not sure how to drill down into the team object or the coach object.
<ngx-datatable class="ngx-datatable" [rows]="standingsAFCEast">
<ngx-datatable-column name="team.teamName" [width]="300"></ngx-datatable-column>
<ngx-datatable-column name="team.coach.coachName"></ngx-datatable-column>
<ngx-datatable-column name="won"></ngx-datatable-column>
</ngx-datatable>
Any advice would be really appreciated!
After looking at the basic examples, I made this work (Plunker here):
#Component({
selector: 'my-app',
template: `
<div>
<ngx-datatable
[rows]="rows"
[columns]="columns"
[columnMode]="'force'"
[headerHeight]="50"
[footerHeight]="50"
[rowHeight]="'auto'"
[reorderable]="reorderable">
</ngx-datatable>
</div>
`
})
export class AppComponent {
standingsAFCEast = [{
"team":{
"teamId":22,
"teamName":"Carolina Panthers",
"coach":{
"coachId":61,
"coachName":"J Smith"
},
"division":{
"divisionId":2,
"divisionName":"NFC West"
},
"headerImage":"",
"logoImage":"",
"hex":"",
"r":null,
"g":null,
"b":null
},
"won":2,
"lost":1,
"tied":0,
"pointsFor":82,
"pointsAgainst":62,
"pointsDifference":20
}]
get rows () {
return this.standingsAFCEast.map(standing => ({
team: standing.team.teamName,
coach: standing.team.coach.coachName,
w: standing.won,
l: standing.lost,
t: standing.tied,
fa: standing.pointsFor,
agst: standing.pointsAgainst,
diff: standing.pointsDifference
}))
}
// columns = [{name:'team'}, {name:'coach'}, {name:'w'}, {name:'l'}, {name:'t'}, {name:'fa'}, {name:'agst'}, {name:'diff'}]
columns = Object.keys(this.rows[0]).map(val => ({name: val}))
}
Let me know if this helps!
I have two JSON objects defined in a controller (NotificationsController). One with all the notifications and another one with only the ID of the newest notifications (last 3 days).
Format of object "notifications": (t_notifications)
[{"0":"1","1":"4","2":"14-APR-16","3":"ALERT 1","ID":"1","ID_USER":"4","DATE":"14-APR-16","NOTIFICATION":"ALERT 1!"},{"0":"2","1":"1","2":"07-APR-16","3":"ALERT 2!","ID":"2","ID_USER":"1","DATE":"07-APR-16","NOTIFICATION":"ALERT 2!"},{"0":"3","1":"1","2":"13-APR-16","3":"ALERT 3!","ID":"3","ID_USER":"1","DATE":"13-APR-16","NOTIFICATION":"ALERT 3!"}]
Format of object "newest notifications": (newest_notifications)
[{"0":"1","ID_NEWNOTIF":"1"},{"0":"3","ID_NEWNOTIF":"3"}]
I'm displaying all the notifications in a view like this:
<div class="panel-body" ng-controller="NotificationsCtrl">
<table datatable="ng" class="row-border hover">
<thead>
<tr>
<th><b>ID</b> </th>
<th><b>ID_USER</b> </th>
<th><b>DATE</b> </th>
<th><b>NOTIFICATION</b> </th>
</tr>
</thead>
<tbody>
<tr ng-repeat="data in t_notifications" ng-class="{selected: data.ID == **TO COMPLETE**>
<td>{{ data.ID }}</td>
<td>{{ data.ID_USER }}</td>
<td>{{ data.DATE }}</td>
<td>{{ data.NOTIFICATION }}</td>
</tr>
</tbody>
</table>
</div>
I would like to know how it is possible to select in my table only the newest notifications - searching through the JSON object newest_notifications - with ng-class?
PS: "selected" is already defined with a blue background color.
Just use a strict filter
... ng-class="{'selected': (newest_notifications | filter : { ID_NEWNOTIF: data.ID } : true).length !== 0 }"
Fiddle - https://jsfiddle.net/dyxf5xqj/
You can use a expression against data.DATE. For example
<tr ng-repeat="data in t_notifications" ng-class="{selected: data.DATE > someDateInThePast}">
