I need to dynamically add templates to kendo ui grid columns based off of user input.
Can I add a template to a grid column after the grid has been created?
Yes, but you must either wait to render the grid after user input or destroy and rebuild it each time the user input changes. Here is a working example. Input a string like <i>#=name#</i> in the Name Template textbox and you'll see how the template can be affected. Come up with more complex templates as you see fit.
Html
<body>
<div id="choices">
<label>Name Template</label>
<input type="text" data-bind="value: nameTemplate"/>
<label>Age Template</label>
<input type="text" data-bind="value: ageTemplate"/>
<button type="button" data-bind="click: buildGrid">Build Grid</button>
</div>
<hr/>
<div id="grid"></div>
</body>
Script
$(function() {
var grid = {};
var columns = [
{ field: 'name' },
{ field: 'age' }
];
var vm = kendo.observable({
nameTemplate: '',
ageTemplate: '',
buildGrid: buildGrid
});
function buildGrid() {
if (vm.nameTemplate !== '') {
columns[0].template = vm.nameTemplate;
}
if (vm.ageTemplate !== '') {
columns[1].template = vm.ageTemplate;
}
grid = $('#grid').kendoGrid({
columns: columns,
dataSource: [
{ name: 'Jacob', age: 42 },
{ name: 'Cindy', age: 28 }
]
}).data('kendoGrid');
}
kendo.bind('#choices', vm);
});

I have inputs that build from objects in array.
Everything got right but when input.type = 'file', Angular change it to text type and i cant figure it out.
Did anything notice this?
My template:
<span ng-repeat="input in formInputs">
<label for="{{input.id}}">{{input.label}}</label>
<input type="{{input.type}}" id="{{input.id}}" name="{{input.name}}" ng-model="input.insert" ng-required="input.must">
</span>
My array:
var formInputs = [
{
label : 'first name',
id : 'id1',
type : 'text',
name : 'name1',
must : true,
insert : ''
},
{
label : 'upload file',
id : 'id2',
type : 'file',
name : 'name2',
must : true,
insert : ''
}
]
My result:
<span ng-repeat="input in formInputs">
<label for="id1">first name</label>
<input type="text" id="id1" name="name1" ng-model="input.insert" ng-required="input.must">
<label for="id2">upload file</label>
<input type="text" id="id2" name="name2" ng-model="input.insert" ng-required="input.must">
</span>
EDIT:
I have this flowing:
<input type="{{childInput.type}}" id="{{childInput.id}}" name="{{childInput.name}}">
And this array:
var formInputs = [
{
id : 'id',
type : 'file',
name : 'name',
}
]
The resolute [only in Safari]:
<input type="text" id="id" name="name">
Why its happening?
Thanks for your help!
From the AngularJS Documentation for input:
Note: Not every feature offered is available for all input types. Specifically, data binding and event handling via ng-model is unsupported for input[file].
So it looks like Angular falls back to type="text". There are a lot of answers which bring solutions to this, check out:
ng-model for <input type=“file”/>
From that answer, here's a way to deal with a file input.
.directive("fileread", [function () {
return {
scope: {
fileread: "="
},
link: function (scope, element, attributes) {
element.bind("change", function (changeEvent) {
var reader = new FileReader();
reader.onload = function (loadEvent) {
scope.$apply(function () {
scope.fileread = loadEvent.target.result;
});
}
reader.readAsDataURL(changeEvent.target.files[0]);
});
}
}
}]);
As mentionned by Hackerman, his jsfiddle seem to work (with Angular 1.0.1) at first sight, but it doesn't seem to populate the model correctly.
My application has to dynamically list file items using a Radio button, Checkbox and AngularJS custom filter (code given below).
I have tried few options, but could not get the working code.
I have created the fiddle link and find the same below:
https://jsfiddle.net/38m1510d/6/
Could you please help me to complete the below code to list the file items dynamically ?
Thank you.
<div ng-app="myApp" ng-controller="myCtrl">
<label>
<input type="radio" ng-model="inputCreatedBy" value="byX"
ng-click="myFilter(?, ?)"> by X
<input type="radio" ng-model="inputCreatedBy" value="byAll"
ng-click="myFilter(?, ?)"> by All
</label> <br/><br/>
<label>
<input type='checkbox' ng-model='Type1Files' ng-change='myFilter(?, ?)'>Type1 files
<input type='checkbox' ng-model='Type2Files' ng-change='myFilter(?, ?)'>Type2 files
</label>
<br/><br/>
<label ng-repeat="file in displayFiles | filter: myFilter(createdBy, fileType)">
{{ file.name }}
</label>
</div>
</body>
<script>
var app = angular.module("myApp",[]);
app.controller('myCtrl', function ($scope) {
$scope.files = [
{ name: 'file1', type:'Type1', createdBy: 'X' },
{ name: 'file2', type:'Type2', createdBy: 'X' },
{ name: 'file3', type:'Type2', createdBy: 'Y' },
{ name: 'file4', type:'Type1', createdBy: 'Y' }
];
$scope.displayFiles = [];
$scope.myFilter = function() {
return new function(createdBy, fileType) {
var displayFilesTemp = [];
for(i=0;i<$scope.files.length;i++) {
if($scope.files[i].type ==fileType && $scope.files[i].createdBy == createdBy && !checkArrayContainsObject(displayFilesTemp, displayFiles[i])) {
displayFilesTemp.push(displayFiles[i]);
}
}
return displayFilesTemp;
};
};
});
function checkArrayContainsObject(a, obj) {
for (var i = 0; i < a.length; i++) {
if (JSON.stringify(a[i]) == JSON.stringify(obj)) {
return true;
}
}
return false;
}
</script>
Here's a working fiddle - http://jsfiddle.net/1gfaocLb/
Radio is a unique value, so it's easy to filter by.
Selected types are array of values so it's needs a little more attention.
myApp.filter('typesFilter', function() {
return function(files, types) {
return files.filter(function(file) {
if(types.indexOf(file.type) > -1){
return true;
}else{
return false;
}
});
};
});
According the shared code / fiddle, I've simplified the code for a possible solution. The file filtering logic is not foreseen since it was not clear what needed to be done exact.
<body ng-app="myapp">
<div ng-controller="myctrl">
<label>
<input type="radio" ng-model="inputCreatedBy" value="byX"
ng-click="filterFiles()"> by X
<input type="radio" ng-model="inputCreatedBy" value="byAll"
ng-click="filterFiles()"> by All
</label> <br/><br/>
<label>
<input type='checkbox' ng-model='Type1Files' ng-change='filterFiles()'>Type1 files
<input type='checkbox' ng-model='Type2Files' ng-change='filterFiles()'>Type2 files
</label>
<br/><br/>
<label ng-repeat="file in filteredFiles">
{{ file.name }} <br/>
</label>
</div>
</body>
var app = angular.module("myapp",[])
app.controller('myctrl', function ($scope) {
$scope.files = [
{ name: 'file1', type:'Type1', createdBy: 'X' },
{ name: 'file2', type:'Type2', createdBy: 'X' },
{ name: 'file3', type:'Type2', createdBy: 'Y' },
{ name: 'file4', type:'Type1', createdBy: 'Y' }
];
$scope.filterFiles = function(){
// init dict
var files = [];
// loop & check files
angular.forEach($scope.files, function(value, key) {
// do file check and push to files.push when matching with criteria
files.push(value);
});
// set scope files
$scope.filteredFiles = files;
}
// init filter on ctrl load
$scope.filterFiles();
});
First, you don't have to use any directive as ng-if/ng-click to achieve what you want. Just changing how the values are binding into the radio button and checkbox can do the trick. Also you just need to do a custom filter to handle the checkbox selections, since radio button is unique. Take a look on my solution:
angular.module("myApp", [])
.controller('myCtrl', function($scope) {
$scope.files = [
{
"name":"file1",
"type":"Type1",
"createdBy":"X"
},
{
"name":"file2",
"type":"Type2",
"createdBy":"X"
},
{
"name":"file3",
"type":"Type2",
"createdBy":"Y"
},
{
"name":"file4",
"type":"Type1",
"createdBy":"Y"
}
];
})
.filter('typesFilter', function() {
return function(files, types) {
if (!types || (!types['Type1'] && !types['Type2'])) {
return files;
}
return files.filter(function(file) {
return types['Type1'] && file.type == 'Type1' || types['Type2'] && file.type == 'Type2';
});
};
});

SUMMARYI have a list of brands and a list of products. I am using an ng-repeat to show the list of brands, and an ng-repeat with a filter to show the list of products within their respective brands. I want each brand and each product to have a button that shows more about that brand/product. All of these buttons should use the same function on the controller.
PROBLEMThe button that shows more about the brand also shows more about each of that brand's products, UNLESS (this is the weird part to me) I click the button of a product within that brand first, in which case it will work correctly.
CODEPlease see the Plunker here, and note that when you click on 'show type' on a brand, it also shows all the types of the products within that brand: http://plnkr.co/edit/gFnq3O3f0YYmBAB6dcwe?p=preview

JAVASCRIPT
var app = angular.module('myApp', []);
app.controller('MyController', function($scope) {
$scope.brands = [{
name: 'Kewl',
type: 'Cereal'
}, {
name: 'Joku',
type: 'Toy'
}, {
name: 'Loko',
type: 'Couch'
}]
$scope.products = [{
name: 'Kewlio',
type: 'Sugar Cereal',
brand: 'Kewl'
}, {
name: 'Kewliano',
type: 'Healthy Cereal',
brand: 'Kewl'
}, {
name: 'Jokurino',
type: 'Rattle',
brand: 'Joku'
}, {
name: 'Lokonoko',
type: 'Recliner',
brand: 'Loko'
}, {

$scope.showType = function(item) {

}
$scope.filterProducts = function(brand) {
return function(value) {
if(brand) {
return value.brand === brand;
} else {
return true;
}
}
}
});
IMPORTANT NOTE: I realize I could add an attribute to the object (brand.show) and pass the object into the function, then change that attribute to true/false, but I don't want to do this because in my actual application, the button will show a form that edits the brand/product and submits the info to Firebase, and I don't want the object to have a 'show' attribute on it. I would rather not have to delete the 'show' attribute every time I want to edit the info in Firebase.
ng-repeat directive create own scope, when you do
this.show = !this.show
you create/change show property in current scope, if click brand button - for brand scope, that global for product, and when click in product button - for scope concrete product.
To avoid this, you should create this property before clicking button, for example with ng-init, like
ng-init="show=false;"
on element with `ng-repeat" directive
Sample
var app = angular.module('myApp', []);
app.controller('MyController', function($scope) {
$scope.brands = [{
name: 'Kewl',
type: 'Cereal'
}, {
name: 'Joku',
type: 'Toy'

brand: 'Loko'
}, {
name: 'Lokoboko',
type: 'Love Seat',
brand: 'Loko'
}]
$scope.showType = function(item) {
this.show = !this.show;
}
$scope.filterProducts = function(brand) {
return function(value) {

<div ng-app="myApp">
<div ng-controller="MyController as vm">
<div ng-repeat="brand in brands" ng-init="show=false">
<h1>

<div ng-show="show">
{{product.type}}
</div>
</div>
</div>
</div>
</div>
The easiest fix for this, if you don't mind putting temporary properties in your data is the following changes:
<div ng-show="product.show">
{{product.type}}
</div>
and
<div ng-show="brand.show">
{{brand.type}}
</div>
and then in your controller
$scope.showType = function(item) {
item.show = !item.show;
}
Alternatively, if you don't want to touch the object properties, you can create an $scope.shownTypes array and have your click either push the object into or remove the object from the shown array. THen you can check for the object's existence in the array and show or not show the type appropriately. Let me know if you need a sample of that.
Your show boolean attribute same for whole tree (is in same scope). Using angular directive with child scope scope:true in ng-repeat helps to isolate each show property. I have forked your plunker code:
http://plnkr.co/edit/cMSvyfeCQOnTKG8F4l55?p=preview
I have these objects right here that I will use to save data from a form, and later send it to an api as JSON :
$scope.price = {}
$scope.item = {"price":$scope.price, };
I also have these field which will be used to dynamically generate inputs on a html page:
$scope.fields = [
{
name: $scope.item.title,
title: 'Title',
type: {
view: 'input'
}
},
{
name: $scope.price.regular,
title: 'Regualar Price',
type: {
view: 'input'
}
}
];
Now in order to generate the form I use this code:
<div class="form-group" ng-repeat="field in fields">
<label>{{ field.title }}:</label>
<span ng-switch on="field.type.view">
<span ng-switch-when="input">
<input
ng-model=field.name
type="text"
/>
</span>
</span>
</div>
And with this code, it is not assigning the values in the input to the objects. Is there a way to do it? I know I can do it this way:
ng-model="item[field.name]"
But that limits me to only one level of the object. I want to be able to bind nested objects. And I just can't seem to figure it out. Thank You!
I have a data model persons which takes the following form:
personsInfo = {
name: Adam
dob: 31-FEB-1985
docs: [
{
docType: Drivers License,
number: 121212,
selected: false
id: 1
},
{
selected: true,
docType: None
},
{
docType: State ID,
number: 132345,
selected: false,
id: 2
}
]
}
In my markup I have defined the following to dynamically generate radio buttons.
<div ng-repeat="personDoc in personsInfo.docs">
<input type="radio" name="personDocs" ng-model="personDoc.selected" value=""/>
{{personDoc.docType}} <span ng-hide="personDoc.docType === 'None'">Number: {{personDoc.number}}</span>
</div>
I want to be able to check the documents which have selected as true on page load, and then depending on what the user selects save the selected flag in my personsInfo model.
My intent here is to send the personsInfo model back to another page.
If somebody could point me to a working fiddle it would be greatly appreciated!
Thanks!
You're almost there just missing the binding to show which document is selected. We'll add an object to the scope to represent the selected item, then bind the forms to that model.
JS
app.controller('...', function($scope) {
$scope.personInfo = { ... };
$scope.selectedDoc = {};
$scope.$watch('personInfo',function() {
$scope.selectedDoc = $scope.personInfo.docs[0];
});
});
HTML
<div ng-repeat='doc in personInfo.docs'>
<input type='radio' ng-model='selectedDoc' value='doc' /> {{doc.docType}}
</div>
<form>
<input type='text' ng-model='selectedDoc.number' />
...
</form>
