ngRepeat with Table: Change a cell's display text - angularjs

I have a list of mails which I want to show in a grid (<table>). Some of these mails have attachments. For their corresponding rows, I would like to show an attachment icon in the attachment column. For rest, it should be empty.
JsFiddle: http://jsfiddle.net/6s4Z5/
My template is as follows:
<table id="resultTable">
<thead>
<tr>
<th ng-repeat="columnId in schema.columnOrder">
<img src="icon_attach.png" ng-if="columnId == 'hasAttachments'">
{{schema.columns[columnId].displayText}}
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in results.mails">
<td ng-repeat="columnId in schema.columnOrder">
<img src="icon_attach.png" ng-if="columnId == 'hasAttachments' && row.hasAttachments">
<span ng-if="columnId != 'hasAttachments'" >{{ row[columnId] }}</span>
</td>
</tr>
</tbody>
</table>
where schema.columnOrder is an array of columnIds to be shown in the table.
This template is working but is this the best way to implement this? Moreover, I have to add an extra <span> for ng-if statement. Can that also be removed?

You pretty much can change it to something like:
<span ng-if='your check'><img src=''/>{{row[columnId}}</span>

You could set (in the controller) the value of the column hasAttachments to be the image you want to display there.

ng repeat dynamic with key objet json AngularJS

I have a small problem I would like to set up a ng-repeat dynamic with the values I receive from my JSON object,
First, i made my th from my table with the keys
Secondly, i would like to do my td in dynamic (without putting the name of the key ex: obj.NOM, obj.TYPE ...)
I managed to do something with an Object.keys but logic is not good so I need some help
this is my JSON object ( i show you just the little piece of code that I have a problem )
"HEADER":[
{"NOM":"API-APP","TYPE":"string","DESCRIPTION":"Code application"},
{"NOM":"API-SIGNATURE","TYPE":"string","DESCRIPTION":"Signature de la requete API"},
{"NOM":"API-TIMESTAMP","TYPE":"integer","DESCRIPTION":"Timestamp en microseconde"}]
and this is my ng repeat
<span><b>HEADER</b></span>
<br>
<br>
<table class="table">
<th ng-repeat ="(key, itemHeader) in itemHead.HEADER[0] track by $index">{{key}}</th>
<tr ng-repeat ="(key, itemHeader) in itemHead.HEADER track by $index" >
<td>{{getFirstPropertyValue(itemHeader,$index)}}</td>
</tr>
</table>
I explain i made first a ng-repeat for th with the keys and I would like put my data (3 data per row) in td without put ( .NOM .TYPE .DESCRIPTION)
So I took the function object.key which works very well but that makes me just one element per row but I need 3 elements per row
this is my scope for the function object.key
$scope.getFirstPropertyValue = function(obj,index){
return obj[Object.keys(obj)[index]];
}
and this my result
thanks in advance for your help
<table class="table">
<thead>
<tr>
<th ng-repeat="(key, itemHeader) in itemHead.HEADER[0]">
{{key}}
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in itemHead.HEADER">
<td ng-repeat="column in row">
{{column}}
</td>
</tr>
</tbody>

Can some one help me to resolve this. I have table with different columns (TD). I want to select one cell and change its classname. when i click on other cell, i want to restore the classname in previously cell and change the classname on newly selected cell..
Please note: each cell have different classname. So i have to keep track of pervious class and selected element.
This is Angular 4 application.
my table:
<table class="table package-table stats">
<tbody>
<tr *ngIf="deptStatsModel.length>0">
<th (click)="setStatsActByDept($event,dt2,null)" class="st-th">ORG</th>
<th (click)="setStatsActByDept($event,dt2,'OD')" class="OverDue">Over Due</th>
<th (click)="setStatsActByDept($event,dt2,'NA')" class="NeedAttention">Need Att</th>
<th (click)="setStatsActByDept($event,dt2,'IA')" class="InProgress">In Prog</th>
<th (click)="setStatsActByDept($event,dt2,'CP')" class="Comp">Complete</th>

<tr *ngFor="let model of deptStatsModel">
<td (click)="setActivitiesData($event,model, 'all','DPT')">{{model.deptName}}</td>
<td (click)="setActivitiesData($event,model, 'OD','DPT')">{{model.overDue}}</td>
<td (click)="setActivitiesData($event,model, 'NA','DPT')">{{model.needAtt}}</td>

setStatsActByDept(event,dt,type)
{
var target = event.target || event.srcElement ||
event.currentTarget;
this.prevDeptCss=target.cloneNode();
target.className="selected";
.........
}
I dont know what to do next..help please.
You're thinking about it in the wrong way. The code shouldn't modify the DOM. It should modify the state of the component. The template is the one responsible to apply CSS classes to DOM elements based on the state of the component.
Assuming, as your code seems to imply, that you want to select the header cells. Your code should simply look like the following.
In your component:
public selectedHeader: string;
In your view:
<th (click)="selectedHeader = 'ORG'" [ngClass]="selectedHeader === 'ORG' ? 'selected' : 'st-th'">ORG</th>
<th (click)="selectedHeader = 'OverDue'" [ngClass]="selectedHeader === 'OverDue' ? 'selected' : 'OverDue'">Over Due</th>

Expand/collapse odd row in AngularJs

I want to expand/collapse a row, I want to hide all odd rows and on clicking '+' button those hidden row should get visible, my current code is allowing me hide all the odd rows but on clicking '+' button all row are getting visible, my use case is to show only the odd row which is next to clicked even row.
<table class="table table-bordered">
<thead>
<tr>
<th></th>
<th>Name</th>
<th>Type</th>
</tr>
</thead>
<tbody ng-repeat="test in ctrl.SearchResults">
<tr ng-if="$even">
<td>
<button ng-click="ctrl.expanded = !ctrl.expanded" expand>
<span ng-bind="ctrl.expanded ? '-' : '+'"></span>
</button></td>
<td>{{test.apName}}</td>
<td>{{test.type}}</td>
</tr>
<tr ng-show="ctrl.expanded" ng-if="$odd">
<td></td>
<td>{{test.apName}}</td>
<td>{{test.type}}</td>
</tr>
</tbody>
</table>
The reason all the rows expand when you hit the plus, is that the variable expanded is on the controller. So all the rows are 'listening' to the same variable.
As atfornes pointed out in his answer, you could use the $index to identify each row. Another solution is to keep track of the current index on the controller and check for per row if he must be showed:
<tr ng-show="ctrl.expanded == $index" ng-if="$odd">
And on the click event of the plus sign you could have
ctrl.expanded = $index
Or you could handle this in the controller. In this case you can create a method on the controller which accepts the index and then set this index value to the controller's variable expanded.
At the button ng-click code, you could store the current $index with a code like:
<button ng-click="ctrl.expanded = !ctrl.expanded; ctrl.index = $index" expand>
then, you can change the ng-show condition to only display the item if ctrl.expanded and $index === ctrl.index + 1:
<tr ng-show="ctrl.expanded && $index === ctrl.index +1" ng-if="$odd">

table with ng-repeat not displaying correctly

Folks I am using a simple ng-repeat directive to display data in table.
However when the directive renders, the first column takes up all the space and dis-figures the table.
Take a look at the plnkr here :
http://plnkr.co/edit/Hahh4uyQ130zOS8noC3D
please focus on the file layout.html
<table>
<thead>
<tr ng-repeat="element in header" class="header-cells" style="width:{{element.width}}px">
<th drop-down-sort-menu>{{element.column}}</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="element in body">
<td ng-repeat="h in header" row="{{$parent.$index}}" col="{{$index}}" style="width:{{element.width}}px">{{element[h.column]}}
</td>
</tr>
</tbody>
</table>
I am sure it's something minor. any clues
I believe you problem is that for the headers, you have 4 TRs with only one TH, as opposed to one TR with 4 THs. For this reason, the cells on your headers are not matching the cells on your body.
Do the first ng-repeat at the TH level.
Give it a try and let me know.

angularJS - Repeating tr's in a table, but dynamically adding more rows while looping

Since examples always tell more then just words here is what I would like to do in another language
<tr>
<c:forEach items="${items}" var="item">
<td>...</td>
<td>...</td>
<td>...</td>
<c:if test="${item.showWarning}">
</tr><tr><td colspan="3">${item.warning}</td>
</c:if>
</tr>
So this will loop over a set of items and show some properties of these items. If there is a warning, a new row will be added underneath the current row in which the warning will be shown. However, how can I do this in angularJs? If I put a ng-repeat on the tr, it will stop at the first end tag of tr. I have read on some other threads that this is not very easily done, but how can it be done? And yes, I really do want to use a table. Here is my contrived example with angularjs which is obviously not working as I would like it to. Any pointers how this can be done?
JSBin example with tr-ng-repeat
Currently (1.0.7/1.1.5) you can't output data outside the ng-repeat, but version 1.2(see youtube video AngularJS 1.2 and Beyond at 17:30) will bring the following syntax(adapted to your example):
<tr ng-repeat-start="item in items">
<td>...</td>
<td>...</td>
<td>...</td>
</tr>
<tr ng-repeat-end ng-show="item.showWarning">
<td colspan="3">{{item.warning}}</td>
</tr>
The idea is that whatever is between -start and -end will be repeated including the -end element.
One solution that I can think of is having multiple tbody tags within the same table. Here is a discussion on the use of multiple tbody tags within the same table.
So, for your issue, you could have the following setup:
<table ng-controller="ItemController">
<thead>
<th>Name</th>
<th>Description</th>
<th>warning?</th>
</thead>
<tbody ng-repeat="item in items">
<tr>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.warning}}</td>
</tr>
<tr ng-show="item.warning">
<td colspan="3" style="text-align: center">Warning !!!</td>
</tr>
</tbody>
</table>
Repeat the table body as many times as there are entries for the table and within it have two rows - one to actually display the row entry and one to be displayed conditionally.
You can repeat over the tbody
<tbody ng-repeat="item in items">
<tr>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.warning}}</td>
</tr>
<tr ng-show="item.warning">
<td colspan="3">Warning !!!</td>
</tr>
</tbody>
Also you do not need to wrap the ng-show expression in {{}}, you can just use item.warning
