I am creating the row dynamically with multiple select box as one of the form field in Angularjs 1.7.5.
Each row has two Multiple select box [Input & Selected]
View:
<select name="inoutvaluedy" class="custom-select" multiple ng-model="available" ng-options="client as client for client in availableclients"></select>
<button id="moveright" class="btn_arrow_style" type="button" value="Add Client" ng-click="additem(available)"></button>
<button id="moveleft" class="btn_arrow_style" type="button" value="Remove Client" ng-click="removeitem(input)"></button>
<select name="selectedclients" class="custom-select" multiple ng-model="input" ng-options="client as client for client in selectedclients"></select>
Controller:
$scope.availableclients = ["fromEmail", "toEmail", "Content"];
$scope.selectedclients = [];
$scope.columns = [{id: 1, input:$scope.selectedclients}];
$scope.addNewColumn = function() {
var newItemNo = $scope.columns.length + 1;
$scope.columns.push({
id: newItemNo,
input: $scope.selectedclients
}); };
//Add item to selected
$scope.additem = function(items) {
items.forEach(function(item) {
$scope.selectedclients.push(item);
$scope.availableclients.splice(items, 1);
});}
//Remove item from selected
$scope.removeitem = function(items) {
items.forEach(function(item) {
$scope.selectedclients.push(item);
$scope.availableclients.splice(item, 1);
});}
Issue:
When adding row. The multiple Select box repeated with same item.I need to have a unique selected item on each row.
May be my approach would be wrong. Please take a look on my plunker and correct me. Thanks in Advance

I'm building a little Js project in which you can select 2 types of motorcycles, and 3 types of weather, and based on you're choices you will get street and snow tires. But right now im trying to connect an image to the option with an imgArray, but can't figure out how to do it. Right now im using onchange in html, I have to do it with eventlisterner but I didn't get that to work. Here's my code
HTML:
<select id="motor" onchange="selectBike()">
<option value="Allroad">Allroad</option>
<option value="Street">Street</option>
</select>
Js
var imgArray2 = ['KTM790', "KTM790D"];
document.querySelector("img").src = 'Bike/' + imgArray2
function selectBike() {
var x = document.getElementById('motor').value;
document.getElementById("demo").innerHTML =
"you selected " + x;
}
function selectWeather() {
var c = document.getElementById('weather').value;
document.getElementById("demo2").innerHTML = "it's " + c;
}
You need yo have an imgObjects which has the values and the images name
then you can use that code which will create image element and add it
var imgObjects = {
Allroad : "KTM790D",
Street : "KTM790"
}
function selectBike() {
var x = document.getElementById('motor').value;
document.getElementById("demo").innerHTML =
"you selected " + x;
var imgElm = document.createElement("img");
imgElm.src = window.location.hostname + "/Bikes/" + imgObjects[x]+".jpg";
console.log(imgElm)
document.getElementById("demo").appendChild(imgElm);
}
<select id="motor" onchange="selectBike()">
<option value="Allroad">Allroad</option>
<option value="Street">Street</option>
</select>
<p id="demo"></p>
In my case, You can create a JSON object and store image data into the Array object. When you adding image data, you should convert image to the base64 format. here is the link. Here is my solution
<html>
<head><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script></head>
<body>
<select id="bikes" onchange="selBike()">
<option >Allroad</option>
<option >Street</option>
</select>
<div id="demo"></div>
<div id="demo1"></div>
<script>
var imgBikes = [{"imgURL" : "data:image/jpeg;base64,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"},{"imgURL":"data:image/jpeg;base64,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"}];

Thus, you don't need store images your directory. Because image data is now encoded.
So, Don't care about my images...
Thank you!!!
I have modified bit of your code in order to make it as you expected.
HTML:
added 'this' reference to the 'selectBike' event call to access select control in event callback function.
JS:
by default image src is map to first index of given image reference array imgArray2.
using 'this' reference which is passed as an argument we can access the selectedIndex and can change the src of the image accordingly.
var imgArray2 = ['KTM790', "KTM790D"];
//by default
document.querySelector("img").src = 'Bike/' + imgArray2[0];
function selectBike(selectRef) { var x = document.getElementById('motor').value;
document.getElementById("demo").innerHTML = "you selected " + x;
document.querySelector("img").src = 'Bike/' + imgArray2[selectRef.selectedIndex];
}
function selectWeather() { var c = document.getElementById('weather').value;
document.getElementById("demo2").innerHTML = "it's " + c;
}
<select id="motor" onchange="selectBike(this)">
<option value="Allroad">Allroad</option>
<option value="Street">Street</option>
</select>
<div id="demo"></div>
<img src="" alt="">
I've got a simple page selector I'm using in an Angular 1.5 page. The select works for the most part, but the ng-selected part does not.
If I'm on page 3, (which is ironically the last page, not sure if that matters) 3 is selected by default. If I'm on page 1 or 2, the first item (blank) is selected. I'm not super versed in Javascript, but figured it might be a type issue. Tried settings $scope.thisPage with parseInt(page) and page.toString() just in case it did something under the sheets I wasn't aware of, but it all turned out the same.
app.controller('myCtrl', ['$scope','$route','$routeParams', function($scope,$route,$routeParams) {
$scope.pages = [];
var page = $routeParams.p ? $routeParams.p : 1
$scope.thisPage = page;
for (var i = 0; i < 5; i++) {
$scope.pages.push(i);
}
}]);
<form name="myForm">
<select ng-model="selectedPage" ng-change="switchPage(selectedPage)">
<option ng-repeat="p in pages" ng-value="{{p}}" ng-selected="{{p == thisPage}}">{{p}}</option>
</select>
</form>
You need no set selected property
<form name="myForm">
<select ng-model="selectedPage" ng-change="switchPage(selectedPage)">
<option ng-repeat="p in pages" ng-value="{{p}}">{{p}}</option>
</select>
</form>
Instead bind the selectedPage value with thisPage
app.controller('myCtrl', ['$scope','$route','$routeParams', function($scope,$route,$routeParams) {
$scope.pages = [];
var page = $routeParams.p ? $routeParams.p : 1
$scope.selectedPage= page; ////////////////////////////////
for (var i = 0; i < 5; i++) {
$scope.pages.push(i);
}
}]);
ngSelected require an expression as following p == thisPage and not {{p == thisPage}}

I have two select boxes. The second select box populates from first select box.
I have applied a filter for the second select box to populate as per the options selected in first select box. The second select box populates from an array var outputformats = [];
This is my code
HTML
<select name="reporttype"id="reporttype"
ng-init="reporttype='1115'"
ng-model="reporttype">
<option value="1115">Previous Day Composite Report</option>
<option value="1114">ACH Receive</option>
</select>
<select name="outputformat" id="outputformat"
ng-model="outputformat"
ng-options="format for format in outputformats | outputformatfilter: reporttype:this">
</select> Value : {{outputformat}}
Filter
angular.module('myApp.outputformatfilter',[])
.filter('outputformatfilter', function () {
return function (input,selectedreport,scope) {
var outputFormatReport = {"1115":"HTML,PDF","1114":"CSV,EXCEL"};
var outputformats = outputFormatReport[selectedreport].split(',');
return outputformats;
};
});
Now what I want is whenever the options in second select box changes, its first option should be selected by default, that is the first option from the array should be selected by default.
UPDATE:
Updated fiddle, added ng-if= reporttype !== '' to second select box
FIDDLE
On your controller, watch the filtered options and act on that:
function myController ($scope) {
// watch the filtered output formats
$scope.$watchCollection("filteredOutputFormats", function(val) {
// select the first one when it changes
$scope.outputformat = val[0];
});
}
Make sure you assign the filtered results to a $scope variable:
<select name="outputformat" id="outputformat"
ng-model="outputformat"
ng-options="format for format in filteredOutputFormats = (outputformats | outputformatfilter: reporttype:this)">
</select>
JSFIDDLE
Try this:-
var myApp = angular.module('myApp',['myApp.outputformatfilter']);
myApp.controller('mainController',function($scope,$filter){
var outputformats = [];
$scope.outputFormatReport = {"1115":"HTML,PDF,CSV,EXCEL","1114":"PHP,HTML,PDF","default":"CSV,HTML"};
$scope.$watch('reporttype', function (newValue, oldValue, scope) {
outputformats = $scope.outputFormatReport[newValue].split(',');
$scope.outputformat=outputformats[0]
});
});
angular.module('myApp.outputformatfilter',[]).filter('outputformatfilter', function () {
return function (input,selectedreport,scope) {
console.log('input is '+input+' \nReport is '+selectedreport);
console.log(scope.outputFormatReport);
if(selectedreport!= undefined){
var outputformats =
console.log( scope.outputFormatReport[selectedreport]);
outputformats = scope.outputFormatReport[selectedreport].split(',');
console.log(outputformats);
}else{
return {};
}
return outputformats;
};
});

I have created a select tag with multiple to show it as a listbox and not dropdown.
I have a property which should hold the selected schoolclass which consists of multiple properties like: id, schoolclass , subject, schoolclassIdentifier and color.
When I select now an item in the listbox and press the delete button the $scope.activeStep.selectedSchoolclassCodes array contains one string like "Math10b" actually the selectedSchoolclassCodes array should contain an object created from the above properties.
Why is my selected object wrong?
HTML
<div class="col-md-6">
<select size="10" class="form-control col-md-6" multiple ng-model="activeStep.selectedSchoolclassCodes">
<option class="co-md-6" ng-repeat="item in activeStep.schoolclasses" style="background: rgb({{item.color}})" value="{{item.schoolclassCode}}">{{item.schoolclassCode}}</option>
</select>
</div>
CONTROLLER
'use strict';
angular.module('iplanmylessons').controller('EditSchoolclassCodeWizardStepController', function ($scope, wizardDataFactory, SchoolclassCodeViewModel) {
$scope.activeStep.schoolclassCodeColors = [
'255,165,0',
'255,255,0',

];
$scope.activeStep.selectedSchoolclassCodes = wizardDataFactory.schoolclassCodesAdded[0];
$scope.activeStep.newSchoolclass = "";
$scope.activeStep.newSubject = "";
$scope.activeStep.newSchoolclassIdentifier = "";
$scope.activeStep.schoolclasses = wizardDataFactory.schoolclassCodesAdded;
$scope.activeStep.schoolclassCodeColorsIsOpen = false;
$scope.activeStep.selectedSchoolclassCodeColor = null;
$scope.activeStep.deleteSchoolclassCode = function () {
for (var i = 0; i < $scope.activeStep.selectedSchoolclassCodes.length; i++) {
var index = Enumerable.from( wizardDataFactory.schoolclassCodesAdded).indexOf(function (s) {
return s.schoolclassCode === $scope.activeStep.selectedSchoolclassCodes[i].schoolclassCode;
});
wizardDataFactory.schoolclassCodesAdded.splice(index, 1);
}
$scope.activeStep.selectedSchoolclassCodes = null;
};
$scope.activeStep.schoolclassCode = function () {
return $scope.activeStep.newSubject + $scope.activeStep.newSchoolclass + $scope.activeStep.newSchoolclassIdentifier;
};
$scope.activeStep.setSchoolclassCodeColor = function (item) {
$scope.activeStep.selectedSchoolclassCodeColor = item;
$scope.activeStep.schoolclassCodeColorsIsOpen = false;
};
});
Have you try ng-options? This post has a good explanation of select/ ng-options with array of objects.
Hope it can help.
