Is there a way to use 1 instead of 0 for $index in ng-repeat as the initial item? Im not trying to filter out the first item in the array. It is for paypal they want the first to be item_num_1... using 0 doesnt work
as in
<div ng-repeat = "item in items">
<input type ="hidden" name ="item_num_{{$index}}" value ="item_num_{{item.id}}">
//the rest like this
</div>
Maybe you can try this. I am not sure if it works though. Good luck
<div ng-repeat = "item in items track by $index">
<input type ="hidden" name ="item_num_{{$index + 1}}" value ="item_num_{{item.id}}">
//the rest like this
</div>
Why not to do just
{{$index+1}}

I have a for loop in my MVC application like this
for(var i = 0; i < data.length; i +=2){
<div class='#(i== 0? "item active": "item")'>
<div>
#Html.Raw(data[i].Description)
</div>
<div>
#Html.Raw(data[i + 1].Description)
</div>
</div>
}
I want to convert the above code in angularjs.
Means every loop render the record from current and next array index, say i = 0 then render first and second record detail.
Actually it is big object, for clarity I reduce the code, I want to write the same code in ng-repeat
See the fiddle
I end up with a dirty trick:
<div ng-repeat="item in data"
ng-class="{active: $first}" class="item row"
ng-if='$index % 2 == 0'>
<div class='col-lg-6'>{{ item.a }}</div>
<div class='col-lg-6'>{{ data[$index + 1].a }}</div>
</div>
If $index % 2 == 0 only then render, means 0, 2, 4 .. it work as I want.
See to codepen.
You essentially want something like this:
<div ng-repeat="dataEntry in data" ng-class="{active: $first}" class="item">
<div>{{ dataEntry.Description }}</div>
<div ng-if="!$last">{{ data[$index + 1].Description }}</div>
</div>
Use ng-repeat to loop over your data entries
Use ng-class to only apply 'active' class to the first entry (you have access to $first, $last, $even, and $odd, (which are booleans) inside of an ng-repeat scope)
dataEntry represents each entry for each iteration of your data. Use {{ }} to access and render it's contents
You can use $index + 1 to grab the next entry in the array of entries.
I would assume you know that data in this scenario has to be attached / accessible from your $scope.
I wanna show json data in the client . If server sends an array, it can be handled by *ngfor="item of items", but server can send one row json that can not be implemented with *ngfor, because with *ngfor we can just have an array.
How can implement conditional *ngfor:
<div *ngFor="let item of (Array.isArray(items) ? items : [items])
I want to check items variable , if it is array type, items should be used as an array , otherwise one row jason
Thanks in advance
I would suggest you to create two divs with *ngIf statement, and use ngFor in case server returns an array.
<div *ngIf="Array.isArray(items)" *ngFor="let item of items">{{item}}</div>
<div *ngIf="!Array.isArray(items)">{{items | json}}</div>
It gives better understanding from first sight what is going on in code. Hope it will help
Thanks for your help.
As you recommend I tried following code and it works
<div [ngSwitch]="items.length > 0">
<div *ngSwitchCase="true">
<div *ngFor="let item of items">
<md-checkbox
[checked]= "item[valueKey] == trueValue"
[disabled]="disabled"
align="start"
(change)="onChange($event,item,valueKey)"
(onInputFocus)="onFocus()">
{{item[labelKey]}}
</md-checkbox>
</div>
<md-checkbox
[checked]= "items[valueKey] == trueValue"
[disabled]="disabled"
align="start"
(change)="onChange($event,items,valueKey)"
(onInputFocus)="onFocus()">
{{items[labelKey]}}
</md-checkbox>
</div>
I want to show for every item different description.
This is the controller:
todoApp.controller('todos',function($scope,todoFactory){
todoFactory.getTodos().success(function (data) {
courses = x2js.xml_str2json(data);
$scope.todos = courses.rss.channel.item;
for(var i = 0 ; i < $scope.todos.length ; i++){
item = $scope.todos[i];
console.log(item.description);
$scope.message = item.description;
}
});
this is the html:
<div ng-controller="todos" class="list" style="padding-top: 8%">
<div class="list card" ng-repeat="todo in todos | filter:search" >
<div class="item item-avatar" ng-click="openLink(todo.link)" >
<img src="Bla-Bla-Logo-1.png">
<h2>{{todo.title}}</h2>
<p>{{todo.pubDate | limitTo:25 }}</p>
</div>
<div class="item item-body">
<p ng-bind-html="message"></p>
<p>

<!--end list card-->
</div>
<!--end todos-->
Just to explain the code I get xml and convert into json so todos is array of objects.
Message is entering every object and get the description (but in the description has tags so i use ng-bind-html directive to show it properly).
I understand that $scope.message will hold just the last description. How to make it to belong in the ng-repeat so I can get different description for different item?
Thanks.
replace
<p ng-bind-html="message"></p>
with
<p ng-bind-html="todo.description"></p>
please provide the data which is you want to displayed repeatedly.
How data is represented.You are getting last one because it is overriding.
The "ngBind" attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.
Typically, you don't use "ngBind" directly, but instead you use the double curly markup like {{ expression }} which is similar but less verbose.
So, I'm actually new to angularJS and I've been searching for a while and trying different ways to achieve something, but it seems impossible, to me.
I have this ng-repeat that should show only one of my 6 position array. When I click in "Change", than I should load the second and then the third and so on, until all my data have been accessed and changed by the user, that's why I limited it to 1.
The Professor's select should load according to a parameter from the current ng-repeat class. I have no idea how to solve this problem. I'm trying right now to use a service to load the professor's dropdown, but with no success.
<div class="row" **ng-repeat="class in classes | offset:currentPage | limitTo: 1"** on-finish-render="ngRepeatFinished">
<div style="display: block;">
<div>
<p><label for="">Change:</label> {{ class.professorName }}</p>
</div>
<div>
<p><label for="">By:</label>
<select id="professor" name="professor" class="form-control">
<option ng-repeat="professor in professors" value="{{professor.id}}">{{ professor.name }}</option>
</select>
</p>
</div>
</div>
</div>
<hr>
<center><button type="button" ng-click="change(class.classId)" class="btn btn-primary">Change</button></center>
</div>
What's the best way to achieve something like this (Show only one item each time and after user submits the form, go to the next position... and for each ng-repeat item, I have to reload the professors dropdown)?
Thank you!
Am I understanding you correctly, you want
ng-repeat class in classes //limit 1 //index i.e. [0] +1 change index after button click so you move to the next class index location?
If your setting a value of professor.id in the class or a property that isn't set or is null/undefined before the button, then just add this to your parent div with the loop of class in classes.
ng-if="!class.propName" //if property/dropdown not set
If this isn't what your looking for please expand on your question.
I'm trying to create some functionality where the user would have an input box and all the data (li's) below are hidden.
Then when a user types into the input box, those li's that match that text are show.
What would the best way to do this using angular? I've set up plunker below:
http://plnkr.co/edit/T6JOBJE4LrAtshbmaoPk?p=preview
I was thinking of setting the li's to:
li {
display: none;
}
and then was going to try an ng-if with the ng-model as the value. Something like this:
<div class="input-group">
<span class="input-group-addon" id="basic-addon1">Search</span>
<input type="text" class="form-control" ng-model="search">
</div>
<ul>
<li ng-repeat="x in data | filter:search " ng-if="!search">{{x.name}}</li>
</ul>
Can someone help point me in the right direction? Even if its just explaining the logic.
You can just set ng-show attribute to your <ul> tag, where you will watch on length of search variable and if it's greater that zero, your list with filtered results will be shown. So, you don't need any css.
<ul ng-show="search.length">
<li ng-repeat="x in data | filter:search ">{{x.name}}</li>
</ul>
Demo on plunker.
Part of your problem is the filter matches on the empty search string. You could create a custom filter to handle this, something like this http://plnkr.co/edit/i4lsuVUmOLO3pbISu7FR?p=preview
$scope.filterName = function(datum) {
console.log($scope.search, datum);
return $scope.search !== '' && datum.name.indexOf($scope.search) !== -1;
};
Used in the template like:
<ul>
<li ng-repeat="x in data | filter:filterName">{{x.name}}</li>
</ul>
Then you would have greater control over the filter if you want to tweak it in future.
