I have an issue with angular, I want to use two nested ng-repeat in a data table where the first get the data, and the second get the name of field to be retrieved from the data (retrieved in the first ng-repeat)
here is what I tried to do with code :
<table md-table flex-order-gt-sm >
<thead md-head>
<tr md-row >
//1st : get the name of fields, not a problem
<th md-column ng-repeat="field in fields">{{item.name}}</th>
</tr>
</thead>
<tbody md-body>
<tr md-row ng-repeat="item in items">
<td md-cell ng-repeat="field in fields" >
//here is the problem I want to get the item that it's field name is field
{{item.{{field}} }}</td>
</tr>
</tbody>
</table>
for example if fields contain :{'a','b','c'}
and items contains {'a':'1','b':'2','c':'3'};
I want for example for the 1st iteration of {{item.{{field}} }} to return 1
Use toString() to retrieve the scope data in an scope object.
<tr md-row ng-repeat="item in items">
<td md-cell ng-repeat="field in fields" >
{{item[field.toString()]}}
</td>
</tr>
Here is the plunker
As an alternative you could also use a filter:
<td md-cell ng-repeat="field in fields | filter: { name: 'field' }">
</td>
You need to get fields collection according to item of items collection after
getFieldsByItem(item)
Then you can get field from fields collection
{{field}}

I am using vue.js library for front-end development.
I came a cross a scenario where my JavaScript method returns a list, which has objects, object's number of properties can change each time after method execution.
example my list can contain these type of objects in 2 different executions.
var obj = {
Name : "John",
2020-Jan: 1,
2020-Jul: 2
}var obj = {
Name: "John",
2020-Jan: 1,
2020-Jul: 2,
2021-Jan: 3,
2021-Jul: 4
}
Since Property name is dynamically changes is there any way to bind to HTML ?
<div >
<table>
<thead>
<tr>
<th v-for ="row in Result.Headers">
{{row}}
</th>
</tr>
</thead>
<tbody>
<tr v-for="item in Result.Data ">
<td>
{{item.2020-Jan}} // Because don't know the number of properties until run time
</td> // No of <td/>'s can change on no of properties.
<td> // exactly don't know how many <td>'s needed there.
{{item.2020-Jul}}
</td> <td>
{{item.2021-Jan}}
</td>
</tr>
</tbody>
</table>
</div>
Is there way to bind these type of object to fronted in vue.js ?
You need to loop over the item's keys again. This will show all the values in the object
<tbody>
<tr v-for="item in Result.Data ">
<td v-for="(value, key, index) in item">
{{value}}
</td>
</tr>
</tbody>
If you want to filter some of them, for instance check that the keys are valid dates you need to add a v-if and use Date.parse to check for this.
<tbody>
<tr v-for="item in Result.Data ">
<td v-for="(value, key, index) in item" v-if="Date.parse(key) !== NaN">
{{value}}
</td>
</tr>
</tbody>
if u wana show all attr-> u can use this:
<ul v-for="item in Result ">
<li v-for="(value,key,index) in item">{{value}}</li>
</ul>
if u wana show all days u can use v-if and compute to complete youself fillter
<div id="app">
<ul v-for="item in Result" >
<li v-for="(value,key,index) in item" v-if="canShow(key)"> index：{{index}}------ key: {{key}} ------ value：{{value}} </li>
</ul>
</div>
<script>
var vue=new Vue({
el:'#app',
data:{
Result:[{
name: 'SkyManss',
2020-Jan: 1,
2020-Jul: 2
},{
name: 'SkyManss2',
2020-Jan: 1,
2020-Jul: 2,
2021-Jan: 3,
2021-Jul: 4
}]
},
computed:{
canShow(){
return function(skey){
return skey.indexOf('-') > -1;
}
}
}
});
</script>
after some research and some of your suggestions I came up with an answer.
<div>
<table>
<thead>
<tr>
<th v-for ="row in Result.Headers">
{{row}}
</th>
</tr>
</thead>
<tbody>
<tr v-for="item in Result.Data ">
<td v-for="row in Result.Headers">
{{item[row]}}
</td>
</tr>
</tbody>
</table>
</div>
Javascript code
this.Result.Headers = Object.keys(result.data[0]);
this.Result.Data = result.data;
But this code only worked for the first time. second time data didn't get updated. So I updated JavaScript code to following code.
Vue.set(self.Result, 'Headers', []);
Vue.set(self.Result, 'Result', []);
this.Result.Headers = Object.keys(result.data[0]);
this.Result.Data = result.data;
Vue does not allow dynamically adding new root-level reactive properties to an already created instance. That I got to know from following post.
vue.js is not updating the DOM after updating the array
Thank You All !!!
I have a table that's generated using ng-repeat with some columns headers. On the column headers, I want to columns to be sorted. I included a font-awesome sort icon next to their text and when it's clicked, I call an ng-click with ng-click="sortColumn()". I'm calling this for every column header.
How do I know which column header got clicked on? Right now it fires for each header column.
How do pass the current column in using ng-click?
I tried to pass in this, but it returns the $scope object.
Here's what I have so far:
HTML:
<table class="table">
<thead>
<tr>
<td><b>Product </b><i class="fa fa-sort" ng-click="vm.sortColumn(this)"></i></td>
<td><b>Code </b><i class="fa fa-sort" ng-click="vm.sortColumn(this)"></i></td>
<td><B>Available </b><i class="fa fa-sort" ng-click="vm.sortColumn(this)"></i></td>
<td><B>Price </b><i class="fa fa-sort" ng-click="vm.sortColumn(this)"></i></td>
</tr>
</thead>
<tbody>
{{ vm.noProducts }}
<tr ng-repeat="product in vm.products">
<td>{{ product.productName}}</td>
<td>{{ product.productCode }}</td>
<td>{{ product.releaseDate | date }}</td>
<td>{{ product.price | currency }}</td>
</tr>
</tbody>
</table>
Javascript:
vm.sortColumn = function (obj) {
console.log(obj);
}
I don't think that you can just pass column as object to sortColumn(). If you need column in that function you can loop trough products and make a new array that will be populated for example with all product names.
Maybe that function could look like this:
function getColumn(val){ // 'productName'
var column = [];
for(var i in $scope.products){
column.push(column.push($scope.products[i][val]))
}
return column
}
If you want to sort table you can use orderBy filter.
To your sortColumn() function pass parameter name and in your ng-repeat use orderBy to order column ascending/descending by one of the parameters.
<table class="table">
<thead>
<tr>
<td ng-click="sortColumn('productName')"><b>Product </b></td>
<td ng-click="sortColumn('productCode')"><b >Code </b></td>
<td ng-click="sortColumn('releaseDate')"><b >Available </b></td>
<td ng-click="sortColumn('price')"><b >Price </b></td>
</tr>
</thead>
<tbody>
<tr ng-repeat="product in products | orderBy: criteria">
<td>{{ product.productName}}</td>
<td>{{ product.productCode }}</td>
<td>{{ product.releaseDate | date }}</td>
<td>{{ product.price | currency }}</td>
</tr>
</tbody>
</table>
In your controller set default value for orderBy criteria. (I used here productName)
$scope.criteria = 'productName';
$scope.sortColumn = function(val){
console.log(val)
if($scope.criteria == val){
$scope.criteria = "-"+val;
} else {
$scope.criteria = val;
}
If user clicks on productCode for example, all rows will be sorted by that criteria ascending ('productCode'), if user click on productCode once again all will be sorted descending by criteria '-productCode'
I created small plunker to demonstrate that. Hope it helps.
Here is what I am trying to do:
<tr ng-repeat = "data in tabularData track by $index" >
<td ng-repeat ="(key,value) in usedAttributes" >{{data[key]}}</td>
</tr>
This DID work when the tabular Data was structured like this:
[3920F0-3434D3-ADF-3SDF:[{CreatedBy: "John Doe", CreatedDate: "10-20-2016"}]
However when I flattened it out, it looks more like this:
[{CreatedBy: "John Doe", CreatedDate: "10-20-2016",PrimaryID:"3920F0-3434D3-ADF-3SDF"}]
This does not work. I feel like I'm missing something very obvious.
usedAttributes is just a simple object array containing attributes (column data). The idea is that the user can choose the attributes they want to get so the data table is very dynamic. For this example, the usedAttributes may look like this:
["CreatedBy": [{Checked:false}],"CreatedDate":[{Checked:true}]]
Thus the user wants to see these two attributes although more exists.
You can do this,
<div ng-controller="listController">
<table class="table table-striped">
<thead>
<tr>
<th ng-repeat="(key, value) in tabularData[0]">{{key | uppercase }}
</th>
</tr>
<tbody>
<tr ng-repeat="val in tabularData">
<td ng-repeat="cell in val">
<input type="text" ng-model="cell">
</td>
</tr>
</tbody>
</table>
</div>
DEMO
The Array I use is [{"cell":["jobcode","resume_number","score"]},{"cell":["jc100","rc1",80]},{"cell":["jc100","rc123",70]}]
And I came up with javascript code as
var cell=response;
for (var i in cell) {
for(var j in cell[i])
{
console.log(cell[i][j]);
profiles.push(cell[i][j]);
$scope.profiles=profiles;
for(k in cell[i][j])
{
resumes.push(cell[i][j]);
console.log("resume length"+resumes.length);
$scope.columns=resumes;
console.log(JSON.stringify($scope.columns));
}
}
}
And html is
<tr ng-repeat="profile in profiles track by $index" >
<td ng-repeat="col in columns track by $index">
<label >{{col.cell}}</label>
</td>
</tr>
And ended up enter image description here
I have no idea to proceed further. I need to organize those data as a table. Please help.
Your data contains an array of objects which contains another array. Therefore, you need to extract each object from outer array and then go down to inner one.
If you need this data only to organise them in a table, then you can simply use the following code:
Your Controller code:
$scope.cell = response;
Your HTML :
<tr ng-repeat="profile in cell track by $index" >
<td ng-repeat="col in profile.cell track by $index">
<label >{{col}}</label>
</td>
</tr>
In case you need to store each array object, then you can use forEach loop:
Your controller code:
var cell=[{"cell":["jobcode","resume_number","score"]}, {"cell":["jc100","rc1",80]}, {"cell":["jc100","rc123",70]}];
angular.forEach(cell, function(data){
$scope.profiles.push(data);
});
Your HTML :
<table>
<tr ng-repeat="profile in profiles track by $index" >
<td ng-repeat="col in profile.cell track by $index">
<label >{{col}}</label>
</td>
</tr>
</table>
Try the following code. Take header as separate part from json and display header first then start ng-repeat from index first
<table border="1">
<tr>
<td>
{{columns[0].cell[0]}}
</td>
<td>
{{columns[0].cell[1]}}
</td>
<td>
{{columns[0].cell[2]}}
</td>
</tr>
<tr ng-repeat="col in columns" ng-if="$index>0">
<td>
{{columns[$index].cell[0]}}
</td>
<td>
{{columns[$index].cell[1]}}
</td>
<td>
{{columns[$index].cell[2]}}
</td>
</tr>
</table>
I have a directive that creates a list, I'm trying to get the column sorting to work, so I created another directive for sorting the columns.
I get this error in the console while I'm trying to set up an orderby filter on that list:
http://errors.angularjs.org/1.2.0rc1/$injector/unpr?p0=orderbyFilterProvider
here's my plunker: http://plnkr.co/edit/SiBDuylEv1LUCuWCv5Ep?p=preview
here's where the orderby is:
<table>
<tr>
<th ng-repeat="column in columns">
<sort-by onsort="onSort" sortdir=filterCriteria.sortDir sortedby=filterCriteria.sortedBy sortvalue="{{column.value}}">{{column.title}}</sort-by>
</th>
</tr>
<tr ng-repeat="item in set | orderby:sortBy:reverse" ng-class="getClass(item)" ng-click="selectItem(item,$event,$index)" ng-dblclick="details(item)">
<td ng-repeat="column in columns">{{item[column.value]}}</td>
</tr>
</table>
