I am trying to pass the value from table to text box in angularjs. value should be pass when i click 'pass the value' button. can anyone help me with this?
my code is shared below:
angular.module('app', [])
.controller('controller', function($scope) {
$scope.array = [{
id:1,
name: 'name1',
address: 'address1'
}, {
id:2,
name: 'name2',
address: 'address2'
}, {
id:3,
name: 'name3',
address: 'address3'
}];
$scope.edit=function(id){
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.9/angular.min.js"></script>
<body ng-app="app" ng-controller="controller" class="container">
<table class="table table-condensed">
<tr>
<th>id</th>
<th>name</th>
<th>address</th>
</tr>
<tr ng-repeat="item in array" >
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.address}}</td>
<td><button ng-click="edit(item.id)">pass the value</button></td>
</tr>
</table>
<form>
name <input type="text" ng-model="item.name" />
address <input type="text" ng-model="item.address"/>
</form>
</body>
Instead of just passing the id, pass the whole item to the edit function:
<button ng-click="edit(item)">
Then you can set the item on scope to the passed item:
$scope.edit=function(item){
$scope.item = item;
};
Plunkr
You should assign your index in a variable in click function. Like
<button ng-click=" newIndex = $index; ">pass the value</button>
And fetch this indexed value from array. Like
name <input type="text" ng-value="array[newIndex].name" />
address <input type="text" ng-value="array[newIndex].address"/>
Make sure to declare newIndex in your controller first. Like
$scope.newIndex = null;

Consider the snippet:
JS
var mod = angular.module('module', []);
mod.controller('controller', function($scope) {
$scope.items = [{
id: 1,
label: 'aLabel',
subItem: {
name: 'aSubItem'
}
}, {
id: 2,
label: 'bLabel',
subItem: {
name: 'bSubItem'
}
}]
$scope.getValue = function(ngmodel) {
// some code goes here...
}
});
HTML
<body ng-controller='controller'>
<div>
<table>
<tr ng-repeat='count in counter'> // 5 times
<td>
<select ng-options="item.id as item.label for item in items"
ng-model="selected[$index]">
</select>
</td>
<td>
{{getValue(1)}}
</td>
<td>
</td>
</tr>
</table>
</div>
</body>
As soon as I select some value from the dropdown (select tag) in the first column, I notice that the function in the second column is triggered? What is the reason for this? What exactly is happening behind the scenes?
The reason is you are doing it inside ng-repeat
<tr ng-repeat = 'count in counter'>
You need to pass the object on the controller, in order to do some action on the same.
{{getValue(obj)}}

And I want to save object of sport and punctuation in an array, if there are one or more sports selected save it in the array like this:
likes[
{sport: 'futball', points: 1}, {sport: 'tennis', points: 1}
]
thanks!
You have to keep practicing your English a little bit more (you can ask me on the comment section in spanish if you are strugling)
I think what you are trying to do is to have a single select to be able to choose the sport and score,
Html:
<body ng-app="myapp">
<div class="main-container" ng-controller="main" ng-init="darr.dept=dept2">
<div class="client-area">
<label fo.table-container tabler="txt">Score</label>
<input type="text" id="name-txt" placeholder="Assign the score" ng-model="name">
<br />
Sport
<select ng-model="dept" ng-options="deptOpt.value as deptOpt.name for deptOpt in deptList"></select>
<br />
<button ng-click="add()">Add Item</button>
<table id="tab">
<thead>
<tr id="trow">
<th>Score</th>
<th>Sport</th>
<th>Options</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="ar in arr">
<td>{{ar.name}}</td>
<td>{{ar.dept}}</td>
<td>
<button ng-click="del($index)">Delete</button>
</td>
</tr>
</tbody>
</table>
</div>
</div>
</body>
js:
var app = angular.module("myapp", []);
app.controller('main', function ($scope) {
$scope.arr = [];
$scope.deptList = [{
name: 'Football',
value: 'football'
}, {
name: 'Tennis',
value: 'Tennis'
}, {
name: 'Baseball',
value: 'baseball'
}];
$scope.dept = "football";
$scope.name = "";
$scope.add = function () {
this.arr.push({
name: this.name,
dept: this.dept
});
};
$scope.del = function (ind) {
this.arr = this.arr.splice(ind, 1);
};
$scope.editStudent = function(student) {
console.log(student);
};
});

I am using Checklist model directive with my App. I have issue, if -
I click select all button though it write up the array but its not
selecting checkbox. Same issue with Uncheck All though it empty the
model but it doesn't uncheck checkboxes.
If I select 2 or 3 randomly checkbox and click Select All Button it doesn't select All check-boxes.
Though its writing values to pushArray. But issues are checking and unchecking checkboxes.
$scope.items = [{id:1, name:"abc"},{id:2, name:"def"},{id:3, name:"ghi"}];
$scope.pushArray = [];
<table>
<tr ng-repeat="e in items">
<td class="text-right">
{{e.id}}
<input type="checkbox" checklist-change="imChanged()" checklist-model="pushArray" checklist-value="e.id" >
</td>
</tr>
</table>
I think you are pushing the complete list of object which is wrong. You just need to map the list and pass the id to the $scope
Edit: Works fine when you use $scope.pushArray as an object instead of array.

{{pushArray.ids | json}}

<button ng-click="select_all();">Select All</button>
<button ng-click="unselect_all();">Unselect All</button>

var app = angular.module('app', ["checklist-model"]);
app.controller('selection', ['$scope', function($scope) {
$scope.items = [{
id: 1,
name: "abc"
}, {
id: 2,
name: "def"
}, {
id: 3,
name: "ghi"
}];
$scope.pushArray = { ids: []}; // Works fine when using it as an object
//$scope.pushArray = [];
$scope.select_all = function() {
$scope.pushArray.ids = $scope.items.map(function(item) { return item.id; });
};
$scope.unselect_all = function() {

Hope it works for you!
I updated the examples on checklist-model and fix this issue. Check them out http://vitalets.github.io/checklist-model/
Someone help me please!
Lets say I have an a list of a checkboxes, each checkbox have an ID.
I would like to $scope an array with checked checkboxes IDs.
<div ng-app="myapp">
<div ng-controller="ctrlParent">
<table>
<tr ng-repeat="(key, value) in providers">
<td><input type="checkbox" ng-model="ids[value.Id]"> {{value}} </td>
</tr>
</table>
{{ids}}
</div>
And my controller:
var app = angular.module('myapp',[]);
app.controller('ctrlParent',function($scope){
$scope.providers = [{Id:5},{Id:6},{Id:8},{Id:10}];
$scope.ids = {};
});
Now my array output (if all check boxes are checked) is: {"5":true,"6":true,"8":true,"10":true}
And I would like: [{Id:5},{Id:6},{Id:8},{Id:10}]
this is a possible solution:
<input type="checkbox" ng-model="ids[$index]" ng-true-value="
{{value}}" ng-false-value="{{undefined}}"/>{{value}}
In this way, you will have an array of objects, because you are assigning ids[$index] = value.
There is a cons however: when you double check a checkbox, you will have an empty element in the array.
var app = angular.module('myapp', []);
app.controller('ctrlParent', function($scope) {
$scope.providers = [{
Id: 5
}, {
Id: 6
}, {
Id: 8
}, {
Id: 10
}];
$scope.ids = [];
$scope.$watchCollection('ids', function(newVal) {
for (var i = 0; i < newVal.length; ++i) {
console.log(newVal[i]);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<div ng-controller="ctrlParent">
<table>
<tr ng-repeat="(key,value) in providers">
<td>
<input type="checkbox" ng-model="ids[$index]" ng-true-value="{{value}}" ng-false-value="{{undefined}}" />{{value}}
</td>
</tr>
</table>{{ids}}</div>
</div>
http://jsfiddle.net/b9jj0re2/3/
<input type="checkbox" ng-model="ids[$index]" ng-true-value="{{value}}" >
Addign the ng-true-value directive will solve the problem
and in controller change the ids from object to array

I come from China,my English very poor,so I do a demo.how can I update array inside ng-repeat?
The HTML:
<body ng-app="main" ng-controller="DemoCtrl">
<table ng-table class="table">
<tr ng-repeat="user in users">
<td data-title="'Name'">{{user.name}}</td>
<td data-title="'Age'">{{user.age}}</td>
<td>
{{user.spms|json}}
<div ng-repeat="u in user.spms">
<span ng-bind="u"></span>
<input type="text" ng-model="u" ng-change='updateArray($parent.$index, $index, u)'>
</div>
</td>
</tr>
</table>
</body>
The JS:
var app = angular.module('main', []).
controller('DemoCtrl', function($scope) {
$scope.users = [{
name: "Moroni",
age: 50,
spms: [
6135.7678,
504.4589,
2879.164,
669.7447
]
},
{
name: "seven",
age: 30,
spms: [
34135.7678,
5034.42589,
22879.1264,
63469.72447
]
}
];
$scope.updateArray = function(parent, index, u) {
$scope.users[parent].spms[index] = u * 1; // multiply by one to keep the value a Number
}
})
There are issues here are every update is changing the scope, so you can only change one time them click then change - so I would recommend add a update values button and implementing more or less the same logic to update the array values.
