My code is quite simple. I only want to add John and Marie to my table.
Works great but my issue is if there is no John and Marie I want to create a row and show a - in my td.
How do I know if there was not added any row when the ng-repeat ends?
<tr class="text-center" ng-if="name == 'John' || name == 'Marie'" ng-repeat="name in vm.names track by $index">
<td>{{name}}</td>
</tr>
Use the ng-switch directive:
<tr class="text-center" ng-switch"name" ng-repeat="name in vm.names track by $index">
<td ng-switch-when="John">{{name}}</td>
<td ng-switch-when="Marie">{{name}}</td>
<td ng-switch-when="Paul">{{name}}</td>
<td ng-switch-default>-</td>
</tr>
You could map your original object in the controller with something like this:
this.names = this.names.map(name => {
name ? name : '-';
})

I'm trying to teach myself AngularJS, and I've been staring at this piece of code for so long, my eyes are starting to cross.
I have a JSON file of cats containing the properties name, sex, color, pattern, and picture for each cat object. (sex in this case is a Boolean; 0 for female and 1 for male. This will come back up soon.)
I use the following code to loop through the JSON file and print out a table of all cat objects, and it works correctly (and even pretties up the formatting a bit):
<table>
<tr>
<th>Name</th>
<th>Sex</th>
<th>Color</th>
<th>Pattern</th>
<th>Picture</th>
</tr>
<tr ng-repeat="kitty in cats">
<td>{{kitty.name|capitalize}}</td>
<td ng-if="kitty.sex == 0">Female</td>
<td ng-if="kitty.sex == 1">Male</td>
<td>{{kitty.color|capitalize}}</td>
<td>{{kitty.pattern|capitalize}}</td>
<td ng-if="kitty.picture"><img ng-src="{{kitty.picture}}" alt="{{kitty.name|capitalize}}"></td>
<td ng-if="!kitty.picture">NO IMAGE</td>
</tr>
</table>
What I would like now is to allow a user to click a checkbox, e.g. "Male", and have the view change to display all cat objects where sex is 1. I can achieve this by replacing:
<tr ng-repeat="kitty in cats">
...with...
<tr ng-repeat="kitty in cats | filter:{'sex': 1}">
...but for obvious reasons, I would much prefer to have this functionality available dynamically, rather than hard-coded.
I've tried various ng-models as well as names, ids, and values on a given checkbox, but I have yet to figure out the correct syntax with which to pass the argument 1 to the repeat function, to have it filter the cats as necessary.
Does anyone have any ideas on how these two should be bound?
you probably want this:
HTML
<table>
<tr>
<th>Name</th>
<th>Sex</th>
<th>Color</th>
<th>Pattern</th>
<th>Picture</th>
</tr>
<tr ng-repeat="kitty in cats | filter : {sex: genderFilter}">
<td>{{ kitty.name }}</td>
<td>{{ kitty.sex ? 'Male' : 'Female' }}</td>
<td>{{ kitty.color }}</td>
<td>{{ kitty.pattern }}</td>
<td ng-if="kitty.picture">
<img ng-src="{{kitty.picture}}" alt="{{kitty.name|capitalize}}">
</td>
<td ng-if="!kitty.picture">NO IMAGE</td>
</tr>
</table>
<label>
<input type="checkbox"
ng-true-value="1"
ng-false-value
ng-model="genderFilter">Male
</label><br>
<label>
<input type="checkbox"
ng-true-value="0"
ng-false-value
ng-model="genderFilter">Female
</label>

You can send filter value dynamically based on selected checkbox value.
<table ng-repeat="cat in cats | filter : { sex: selectedGender }" style="width:300px">

What is the best way to compare two different objects for equality inside of ng-repeat, why doesn't angular.equals work for me here:
<tr ng-repeat="row in ctrl.filteredItems" ng-class="{'active':angular.equals(row,ctrl.ngModel), 'focus': angular.equals(row,ctrl.focusedRow)}">
<td ng-repeat="value in ctrl.sort(row) track by $index" class="text-center">
{{value}}
</td>
</tr>
I want to add the active class if the current row and the pre-selected row coming from the controller match.
Write a function in JS which will do angular.equals(obj1, obj2) and use this function to check is it active or not?
HTML
<tr ng-repeat="row in ctrl.filteredItems" ng-class="{'active': checkEqualiy(row, ctrl.ngModel), 'focus': checkEquality(row,ctrl.focusedRow)}">
<td ng-repeat="value in ctrl.sort(row) track by $index" class="text-center">
{{value}}
</td>
</tr>
JS
$scope.checkEquality= function(param1, param2){
return angular.equals(param1, param2)
}
So I'm calling a JSON string, and I want to split it in two at the ":" and use the two values to show in two separate td tags.
function testCtrl($scope) {
$scope.response = {"name":["The name field is required."],"param":["Hobby: Coding", "Country: USA"]};}
to visualize a little more at what I'm trying to do http://jsfiddle.net/8mnxLzc1/5/
You could try this:
<table>
<tr ng-repeat="resp in response.param">
<td ng-repeat="val in resp.split(':')">{{ val }}</td>
</tr>
</table>
Fiddle
This is a entirely angular solution, no need to call the function split in the ng-repeat.
https://jsfiddle.net/kLjzh565/
<table>
<tr ng-repeat="resp in response.param track by $index">
<td ng-repeat="i in [$index]">
{{response.param[i]}}
</td>
</tr>
</table>
I have the following array in my module in Angular.js:
$scope.hsbody = []; //Data array
$scope.hsresult = []; //Data array
$scope.hsProcess = []; //Boolean array
$scope.hssuccess = []; //Boolean array
$scope.hsfailure = []; //Boolean array
$scope.hsExpand = []; //Boolean array
$scope.hsExpandUser = []; //Boolean array
I want to show the array items in my Html page:
hsresult
hsbody
hsresult
hsbody
and so on..
So I do the following:
<div>
<pre>
<table class="table table-condensed">
<tr ng-repeat="hs in hsbody track by $i" ng-show="hsProcess[i] && !hssuccess[i] && !hsfailure[i]" class="warning"><td><div class="glyphicon"></div>{{hsbody}}</td></tr>
<tr ng-show="hssuccess" ng-repeat="highstate in hsbody track by $i" class="success"><td><div class="glyphicon" ng-show="!hsExpand[i]"></div><div class="glyphicon" ng-show="hsExpand[i]"></div>{{ hsresult[i] }} </td></tr>
<tr ng-show="hsfailure" ng-repeat="hs in hsbody track by $i" class="danger"><td><div class="glyphicon" ng-show="!hsExpand"></div><div class="glyphicon" ng-show="hsExpand[i]"></div>{{ hsresult[i] }}</td></tr>
<tr ng-repeat="hs in hsbody track by $i" ng-show="(hsProcess[i] && hsExpand[i]) || (hsExpand[i] && hsfailure[i])" class="active"><td><pre>{{ hsbody[i] }}</pre></td></tr>
</table>
</pre>
</div>
The problem is that nothing is shown in my HTML. but when I get rid of the ng-repeat and use i=0, then I can see the values.
It seems that I don't use the ng-repeat correctly, but I don't know where I wrong.
Inside anything with 'ng-repeat' you'll have to reference everything through whatever you specified in the ng-repeat.
e.g. say you had an array, 'main', in the controller 'data'.
You have usernames in objects within data.main
$scope.main = [
{username: 'jeff'},
{username: 'brad'},
]
or
this.main = [
{username: 'jeff'},
{username: 'brad'},
]
If you wrote
<div ng-repeat="theData in data.main track by $i">
{{ data.main.username }}
</div>
an error would come up, because it's undefined.
If you wrote
<div ng-repeat="theData in data.main track by $i">
{{ theData.username }}
</div>
you would get what you wanted.
The reason is that you are specifying theData as the source of everything inside the ng-repeat.
theData is equivalent to data.main, for inside the ng-repeat
You can't access anything outside the object data.main inside the div.
If you need anything from outside, think again. Do you really want that data printed however many times?
if you want to use the "track by" with index, you should write there: "track by $index".
good luck!
this works for you?
<div>
<pre>
<table class="table table-condensed">
<tr ng-repeat="hs in hsbody track by $index" ng-show="hsProcess[$index] && !hssuccess[$index] && !hsfailure[$index]" class="warning">
<td>
<div class="glyphicon"></div>{{hs}}
</td>
</tr>
<tr ng-show="hssuccess" ng-repeat="highstate in hsbody track by $index" class="success">
<td>
<div class="glyphicon" ng-show="!hsExpand[i]"></div>
<div class="glyphicon" ng-show="hsExpand[$index]"></div>{{ hsresult[$index] }}
</td>
</tr>
<tr ng-show="hsfailure" ng-repeat="hs in hsbody track by $index" class="danger">
<td>
<div class="glyphicon" ng-show="!hsExpand"></div>
<div class="glyphicon" ng-show="hsExpand[i]"></div>{{ hsresult[$index] }}
</td>
</tr>
<tr ng-repeat="hs in hsbody track by $index" ng-show="(hsProcess[$index] && hsExpand[$index]) || (hsExpand[$index] && hsfailure[$index])" class="active">
<td>
<pre>{{ hsbody[$index] }}</pre>

I have a list of items of different types and I would like to display them in a table.
The items of one type will have two columns and items of another type just one. Any suggestions how to change conditionally the colspan on the <> tag on fly?
<div ng-init="items = [
{name:'item1', old:1, new:2},
{name:'item2', old:2, new:2},
{name:'item3', msg: 'message'},
{name:'item4', old:0, new:2}
]">
<table border=1>
<tr ng-repeat="item in items" >
<th>{{item.name}}</th>
<td>{{item.old}}</td>
<td colspan='2'>{{item.msg}}</td>
<td>{{item.new}}</td>
</tr>
</table>
Here is the example to play in jsfiddle: http://jsfiddle.net/38LXt/1/
Thanks!
You can use conditional directives, such as ng-show, to do something like this:
<table border=1>
<tr ng-repeat="item in items" >
<th>{{item.name}}</th>
<td>{{item.old}}</td>
<td colspan="2" ng-show="item.type == 'typeA'">{{item.msg}}</td>
<td ng-show="item.type == 'typeB'">{{item.msgB1}}</td>
<td ng-show="item.type == 'typeB'">{{item.msgB2}}</td>
<td>{{item.new}}</td>
</tr>
</table>
