I have a use case where I have a table, the row data has one way bindings applied, but I have a ng-show/hide conditional based on the same model. I also have a form that changes the model the ng-show/hide is bound to. The problem is, the form is triggering the show/hide when I only want the hide/show attributes to be parsed on load.
Markup:
<td>{{ item.print_id }}</td>
<td>{{ item.customer }}</td>
<td>{{ item.valet }}</td>
<td><span class="{{ ::item.status | lowercase }}">{{ ::item.status }}</span></td>
<td>{{ item.requested_at | date:'MM-dd-yyyy HH:mm' }}</td>
<td>${{ item.price }}</td>
<td><i data-ng-click="openEditForm( item )" class="glyphicon glyphicon-edit"></i></td>
<td><i data-ng-hide="item.status === 'Refunded' || item.status === 'Unused'" data-ng-click="openRefundModal( item )" class="glyphicon glyphicon-retweet"></i></td>
I have a modal with a form in it that changes the value of item.status. The one-way binding in the normal td works as expected but my conditional updates.
I know I could just assign the item.status as a class and hide it that way, but I'd rather see if there's an angular construct first.
Add other bool variable that will change when form is triggered, something like:
<td>{{ item.print_id }}</td>
<td>{{ item.customer }}</td>
<td>{{ item.valet }}</td>
<td><span class="{{ ::item.status | lowercase }}">{{ ::item.status }}</span></td>
<td>{{ item.requested_at | date:'MM-dd-yyyy HH:mm' }}</td>
<td>${{ item.price }}</td>
<td><i data-ng-click="openEditForm( item )" class="glyphicon glyphicon-edit"></i></td>
<td><i data-ng-hide="firstTime && (item.status === 'Refunded' || item.status === 'Unused')" data-ng-click="openRefundModal( item )" class="glyphicon glyphicon-retweet"></i></td>
In the controller inicialization set firstTime = true then in form event code set to false before anything. It's a bit tricky but simple.

I am creating a transaction tracker as a MEAN project and is stuck in here. I need to show all the transactions using ngFor. I want to show the Difference of credit and debit amount with the previous balance added to it after each transaction. Any idea how to do it?
This is my ngFor Code.
<tbody>
<tr *ngFor="let trans of transactions; index as i;">
<td>{{ trans.date | date:'dd-MM-yyyy'}}</td>
<td>{{ trans.billNo }}</td>
<td>{{ trans.description }}</td>
<td>{{ trans.creditAmt }}</td>
<td>{{ trans.debitAmt }}</td>
<td>{{ trans.debitAmt + trans.creditAmt + (DONT KNOW HOW TO ADD THE PREVIOUS BALANCE)}} </td>
</tr>
</tbody>
In my table now you can see, the balance is not being calculated properly.
How can I do this? How to store balance after each ngFor iteration and display it? None of my logic seems to be working.
<tbody>
<tr *ngFor="let trans of transactions; index as i;">
<td>{{ trans.date | date:'dd-MM-yyyy'}}</td>
<td>{{ trans.billNo }}</td>
<td>{{ trans.description }}</td>
<td>{{ trans.creditAmt }}</td>
<td>{{ trans.debitAmt }}</td>
<td>{{ trans.debitAmt + + (DONT KNOW HOW TO ADD THE PREVIOUS BALANCE)}} </td>
</tr>
</tbody>
Well, you have the index. If i != 0..
(trans.creditAmt - trans.debitAmt) + (transactions[i - 1].debitAmt + trasnactions[i - 1].creditAmt)
You should do this in the component, though. As you'll need to create a variable to keep track of the previous balance, as it's also a calculation.
I'm developping web appliccation using AngularJS.
Applicattion show a list of items in a table.
This is the code which prints the table:
<table>
<tr ng-repeat="x in content.listaOperaciones>
<td>{{ x.idOperacion }} </td>
<td>{{ x.idGan }}</td>
<td>{{ x.idEm}}</td>
<td>{{ x.idGate}}</td>
<td>{{ x.idRf }}</td>
<td>{{ x.peso }}</td>
<td>{{ x.duracion }}</td>
<td>{{ x.timestampInicioOperacion | date:'dd-MM-yy HH:mm'}}</td>
</tr>
</table>
This is how the table looks like once is printed in html.
I would like to implement multiple filters in each element in table by using some variables that can be accessed by user.
My idea is to filter each elements inside "ng-repeat" statement by using "ng-show" or "ng-if" statement.
This is the html code where user can modify variables:
<input ng-model="tiempoMinimo">
<input ng-model="$ctrl.PesoMinimo">
<input ng-model="$ctrl.PesoMaximo">
And this is how I'm modifying the table constructor:
<tr ng-repeat="x in content.listaOperaciones | orderBy : $ctrl.orderProp | filter:$ctrl.Busc" ng-if="x.peso > $ctrl.PesoMinimo && x.peso < $ctrl.PesoMaximo">
<div ng-show="x.duracion < $parent.tiempoMinimo">
<td>{{ x.idOperacion }} </td>
<td>{{ x.idGan }}</td>
<td>{{ x.idEm}}</td>
<td>{{ x.idGate}}</td>
<td>{{ x.idRf }}</td>
<td>{{ x.peso }}</td>
<td>{{ x.duracion }}</td>
<td>{{ x.timestampInicioOperacion | date:'dd-MM-yy HH:mm'}}</td>
</tr>
Filtering by using "ng-if" inside "ng-repeat" clausule is working.
Filtering by using "ng show" nested in "ng-repeat" loop is not working...
Since I want to use multiple filters (maybe 10 or 20) I would prefer using "ng-show" directive nested inside "ng-repeat" loop, so code would like easier to understand...
Here you have fiddle with source code working:
https://jsfiddle.net/DSG00/f94sjtty/
Thank you in advance.

Your fiddle isn't working because you can't use div inside tr. Move your ng-show to the tr element where your ng-repeat is. Also change the condition like that !$parent.tiempoMinimo || x.peso > $parent.tiempoMinimo so when your input is empty it won't hide the whole table.
I wanted to display a value in a row in ng-repeat based on the value from the database. i wanted to do some thing like this displayed below
I wanted to display if value T for TRAINER and M for MANAGER. could you give me a simple and efficient way to do it.
I think it is easy if you are used ng-if
<tr ng-repeat="item in list">
<td>{{ item.number }}</td>
<td ng-if="{{item.Role}} == 'TRAINER'">T</td>
<td ng-if="{{item.Role}} == 'MANAGER'">M</td>
</tr>
code not tested. just scratch to get an idea...
You can use ternaries in {{ }}
<tr ng-repeat="data in datas">
<td>{{ data.number }}</td>
<td>{{ data.value == 'T' ? 'TRAINER' : (data.value == 'M' ? 'MANAGER' : data.value) }}</td>
</tr>
I'm trying to transclude a table row (a) in a ng-repeat loop so that another table row (b) can be shown/hidden when a user clicks (a). Both table rows are rendering, however, the <ng-transclude> element - needed to include (a) before (b), in the directive template, is breaking the layout. How can I use a directive to render two table rows without breaking the layout?
// main template
<tr id="a" campaign-item ng-if="vm.campaignData.length > 0" ng-repeat="campaign in vm.campaignData | orderBy:vm.sortBy:vm.sortReverse | filter:searchCampaigns track by $index" ng-click="vm.showCampaignPreview(campaign)">
<td>{{ campaign.name }}</td>
<td>{{ campaign.priority }}</td>
<td>{{ campaign.status }}</td>
<td>{{ campaign.creator }}</td>
<td>{{ campaign.approver }}</td>
<td>{{ campaign.release_date }}</td>
<td>{{ campaign.expiration_date }}</td>
<td><select ng-init="campaignOptions = vm.campaignOptions[0]" name="campaignOption" class="form-control" ng-model="campaignOptions" ng-options="campaign.name for campaign in vm.campaignOptions track by campaign.value"></select></td>
</tr>
// directive
(function(){
'use strict';
angular.module('vsmsCampaignModule')
.directive('campaignItem', campaign)
function campaign(){
var directive = {
link: link,
restrict: 'EA',
transclude: true,
templateUrl: 'app/vsms/admin/campaign/campaign.tpl.html'
};
return directive;
function link(scope, el, attr, ctrl, transclude) {
// do something with clone compiled and linked
// in child scope of directive's scope:
}
}
})();
// directive template
<ng-transclude></ng-transclude>
<tr id="b">
<td colspan="8">{{ campaign.description }}</td>
<td colspan="8">
<div class="row">
<div class="col-lg-1">
<ul>
<li ng-repeat="package in campaign.packages">
{{ package.name }}
</li>
</ul>
</div>
<div class="col-lg-1">{{ campaign.policy }}</div>
<div class="col-lg-1">{{ campaign.region }}</div>
<div class="col-lg-1">
<ul>
<li ng-repeat="vehicle in campaign.vehicles">
{{ vehicle.name }}
</li>
</ul>
</div>
</div>
</td>
</tr>
// update, I solved the issue by simply using ng-repeat-start/end
<tr ng-class-odd="'odd'" ng-class-even="'even'" ng-if="vm.campaignData.length > 0" ng-repeat-start="campaign in vm.campaignData | orderBy:vm.sortBy:vm.sortReverse | filter:searchCampaigns track by campaign.id" ng-click="vm.showCampaignPreview(campaign)">
<td>{{ campaign.name }}</td>
<td>{{ campaign.priority }}</td>
<td>{{ campaign.status }}</td>
<td>{{ campaign.creator }}</td>
<td>{{ campaign.approver }}</td>
<td>{{ campaign.release_date }}</td>
<td>{{ campaign.expiration_date }}</td>
<td>
<select ng-init="campaignOptions = vm.campaignOptions[0]" name="campaignOption" class="form-control" ng-model="campaignOptions" ng-options="campaign.name for campaign in vm.campaignOptions track by campaign.value">
</select>
</td>
</tr>
<tr class="campaign-preview" ng-class-odd="'odd'" ng-class-even="'even'" ng-repeat-end ng-show="vm.selectedCampaign == campaign.id">
<td colspan="8">{{ campaign.description }}</td>
</tr>
I fixed the issue by simply using ng-repeat-start/end (see update above) instead of a directive.
It will require you to rethink your directives a bit but you can use ng-repeat-start and ng-repeat-end to render several TRs per each ng-repeat iteration, like that:
<tr ng-repeat="vehicle in campaign.vehicles"
ng-click='vehicle.showDetails = !!!vehicle.showDetails'>
<td> {{ vehicle.name }} </td>
</tr>
<tr ng-repeat-end ng-show='vehicle.showDetails'>
<td> {{ vehicle.details }}
</td>
</tr>
I'm tring to figure out how I could us the ngSwitch with ngRepeatStart and End on two table rows, where second row is only shown when you click on the top one.
Here's what I've got and want to make work (doesn't work):
<tr
data-ng-repeat-start="user in users | filter : { name: search, active: searchActive }"
data-ng-click="selectUser(user)"
data-ng-switch on="isSelected(user)">
<td>{{ user.name }}</td>
<td>{{ user.email }}</td>
<td>{{ user.active }}</td>
<td>{{ user.dob | date: 'EEEE, dd MMMM yyyy' }}</td>
</tr>
<tr data-ng-repeat-end data-ng-switch-when="true">
<td colspan="4">
{{ user.description }}
</td>
</tr>
and here's what works:
<tbody
data-ng-repeat="user in users | filter : { name: search, active: searchActive }"
data-ng-click="selectUser(user)"
data-ng-switch on="isSelected(user)">
<tr>
<td>{{ user.name }}</td>
<td>{{ user.email }}</td>
<td>{{ user.active }}</td>
<td>{{ user.dob | date: 'EEEE, dd MMMM yyyy' }}</td>
</tr>
<tr data-ng-switch-when="true">
<td colspan="4">
{{ user.description }}
</td>
</tr>
</tbody>
I would like to avoid the wrapping tbody tag and instead use ngRepeatStart / End.
Is there a way of modifying my first example to make it work?
Don't use ng-switch, just use ng-show or ng-if. Here's a plunker
Edit
Okay, I guess if you really want you can use ng-switch, though I would suggest not doing it if all you're doing is checking true/false. Here's the updated plunker. The trick is that the switch needs to be on the second <tr>, and the ng-switch-when needed to be on the <td>.
Now if you need each switch to be a table row, then you're just going to have to use ng-if. The ng-switch attribute needs to be on the parent of all the ng-switch-when's. That's why the switch only works when you put it on <tbody>, or when you switch over <td>'s.
