I am currently trying to invert a table consisting of the following code:
<table>
<tr ng-repeat="x in dataStuff.data track by $index">
<td ng-repeat="y in x track by $index">
y: {{y}}
</td>
</tr>
</table>
I cannot figure out if there is a simple way to invert this table, or if I will have to write a function in JavaScript to rearrange the data.
If you only want that one condition displayed simplest is to just reverse the array in controller before passing to view using Array.prototype.reverse()
$scope.dataStuff.data.reverse()

I have an array that looks like the following:
I want to display that using angularJS ng-repeat, showing both count and value for each.
This is currently the HTML and angular I have but nothing displays.
I also don't need to display the 0 index in the array, I want to start from 1 if possible.
<tr ng-class="" ng-repeat="x in vm.data | filter: searchArray">
<td>{{x.value}}</td>
<td>{{x.count}}</td>
</tr>
I went back to the basics and understood that an ng-repeat is just a loop in javascript, and what do you need to do if you want to access data in JavaScript if your array is multi-dimensional? well you do a nested for loop, and thats exactly what I'm doing in this case.
This is the updated html/angularjs that displays the data I need:
<tbody>
<tr ng-repeat="x in vm.data">
<td ng-repeat="y in x">{{y.value}} {{y.count}}</td>
</tr>
</tbody>
Thank you guys again!
I'm just starting to explore with Angular. Now what I'm trying to do is using an mvc handler that returns a jsonobject. However the returned jsonobject is generic, so it can be different types of object, and they all have a different amount of columns. I want to bind all these columns to a table, but that means i can't just create a fixed amount of columns and bind them like so:
<table class="table">
<tr ng-repeat="r in items">
<td>{{r.ID}}</td>
<td>{{r.Name}}</td>
<td>{{r.FirstName}}</td>
<td>{{r.Telephone}}</td>
<td>{{r.Email}}</td>
</tr>
</table>
this is NOT the way i want it, basically i want to have a table that binds to an object and that creates table columns for every property of the object.
thanks for any advice!
You can iterate the properties of the value like
<tr ng-repeat="r in items">
<td ng-repeat="(key, value) in r">
{{ value }}
</td>
</tr>
Sorry if you find this question's solution is simple or silly.
Need suggestions or solution on this angular part.
I have an object containing array("value"), as shown below.
scope.resp.DefaultData.graphRowData = [
{YName:"Mary", value:[1,4], points:1},
{YName:"Tom", value:[2,5], points:1}
];
My Code viewer uses this style to render the array.
<table>
<tbody>
<tr ng-repeat="rowLabels in resp.DefaultData.graphRowData track by $index">
<th>
<input type="text" value="{{rowLabels.YName}}" ng-model="rowLabels.YName"/>
</th>
<td ng-repeat="value in rowLabels.value track by $index">
<input type="text" ng-model="value"/>
</td>
</tr>
</tbody>
</table>
The html viewer would render like below way:
<table>
<tbody>
<th>Mary</th><td>1</td><td>4</td>
<th>Tom</th><td>2</td><td>5</td>
</tbody>
</table>
Now to my question:
The table displays the data as per the model but if i try to update the table with custom or edit the values, doesn't update the model and the value remains same
For example: Mary has two tags of 1 and 4 values, if I try to change the 1 to 2 and 4 to 5, the data inside the model remains same without update.
Is there any way to fix in my code or should I change the array into array of objects like below
value:[{val:1},{val:4}]
and so ... for other objects under resp.DefaultData.graphRowData? Then it would work fine. Just confused why for array not working in angular js in my code! :(
You need to pass a reference of array instead of value in ng-model
<tr ng-repeat="rowLabels in resp.DefaultData.graphRowData track by $index">
<th>
<input type="text" value="{{rowLabels.YName}}" ng-model="rowLabels.YName"/>
</th>
<td ng-repeat="value in rowLabels.value track by $index">
<input type="text" ng-model="rowLabels.value[$index]"/>
</td>
</tr>

I am making a custom directive which will paginate and make my table sortable. I am trying to make it so that multiple data types will work with the sorting with no effort from the user. Here is my problematic html in my templateUrl:
<tr ng-repeat="row in cndPaginatedObject track by $index">
<td ng-repeat="data in row track by $index" ng-if="!isValidDate(row[cndTableHeaders[$index]])">
{{row[cndTableHeaders[$index]]}}
</td>
<td ng-repeat="data in row track by $index" ng-if="isValidDate(row[cndTableHeaders[$index]])">
{{row[cndTableHeaders[$index]] | date: cndDateFormat}}
</td>
</tr>
I would prefer to use ng-if as opposed to ng-show/hide because it would unnecessarily duplicate DOM elements with ng-show/hide and just not show them. I have tried both ways, but I get the same result either way. The content of columns with dates in them don't show up, but the td itself is still there taking up space. So, I end up having three headers for columns and more than three columns. As far as I was aware, ng-if is supposed to remove the entire element from the DOM.
here is my other code of significance:
scope.isValidDate = (data) => {
var timestamp = Date.parse(data);
return !(isNaN(timestamp));
}
As for cndPaginatedObject, it is just an array of objects with multiple strings contained within. Thank you for any help in advance!
UPDATE:
Just thought I would also add that the cndTableHeaders is literally the table headers. cndPaginatedObject uses the table headers as the keys to each of the values. This way they show up in the proper order in the table.
Two ways to do what you're doing better without the need to produce extra doms and looping a ng-repeat twice
A better way to do what you want to do is
<tr ng-repeat="row in cndPaginatedObject track by $index">
<td ng-repeat="data in row track by $index">
{{(!isValidDate(row[cndTableHeaders[$index]])) ? row[cndTableHeaders[$index]] : row[cndTableHeaders[$index]] | date: cndDateFormat}}
</td>
</tr>
Or add a span inside the with the ng-if logic
<tr ng-repeat="row in cndPaginatedObject track by $index">
<td ng-repeat="data in row track by $index"">
<span ng-if="!isValidDate(row[cndTableHeaders[$index]])>
{{row[cndTableHeaders[$index]]}}
</span>
<span ng-if="isValidDate(row[cndTableHeaders[$index]])">
{{row[cndTableHeaders[$index]] | date: cndDateFormat}}
</span>
</td>
</tr>
Alternatively you could create your own filter which checks if date is valid and then using the date filter to filter it.
I have an angularjs application that basically takes JSON and creates a HTML table, with the keys in the <thead> and the values as table rows.
I have a JSFiddle here where I take the JSON and create table rows based on the values. But I can't figure out how to take the keys and align them with the values as table headers.
My angular code:
<tr ng-repeat='row in rows'>
<td ng-repeat="data in row.data">
{{data}}
</td>
</tr>
and:
function TableController($scope){
$scope.rows = data;
}
Take a look here: How can I iterate over the keys, value in ng-repeat in angular
<tr ng-repeat="(key, value) in data">
<td> {{key}} </td> <td> {{ value }} </td>
</tr>
====EDIT==== Since you're doing it all in the same table, you'll need to do it a different way. You need to separate the header values while you're still in the controller so that you have a clean way to iterate over your list. Here the fiddle: http://jsfiddle.net/L93v5/1/
Your revised way looks bad because there are two different tables and the cell sizes are different. This will keep it all in the same table and make things a bit cleaner.
