I have an API that sends a Json to me. But I don't know how to show it into my html. I know that I have to use Ngfor but it doesn't work. This is my code.
SaveData(){
var dataToSend2 = "Hola";
var dataToSend = {"num_personal":"419","anio_pago":"2022","periodo_pago":"09"};
console.log(dataToSend);
this.proveedor.saveData(dataToSend).subscribe(
(dataReturnFromService)=>{
this.dataFromService = (dataReturnFromService);
let obj = JSON.parse(this.dataFromService);
this.dataFromJson = obj;
console.log(obj);
}
)
}
This part gives me a Json with the data from my API, but I don't know how to use the Json "obj" to show it into the html
you forgot to show your html code. but it should work if it looks like this:
<div *ngFor="let x of dataFromJson">
<span>{{x.label}}</td>
</div>

I am using a query to receive a JSON response. I would like to loop each object (VGF, SSR, BCV, etc..) and output them to premade divs, then the arrays within those objects will loop and create divs within that matching object container.
This is a shortened down version of what I have, and it works mostly. (hopefully, I haven't screwed it up here).
The problem is I have to repeat the searchresult function by copying and pasting the entire function for each object (VGF, SSR, BCV, etc). I would really like to learn how to loop this and not have the same code pasted more than a dozen times.
If I have messed up or left something out of this question, please let me know and I will take care of it.
Here is my ajax request and javascript. I know my problem lies within this loop. I have tried to do a loop inside of a loop, etc. But, when I do that I get no results at all. I am baffled and ready to learn.
$(function getData() {
$("#searchbtn").click(function () {
$.ajax({
url: "action.php",
type: "POST",
data: {},
dataType: "json",
success: function (response) {
console.log(response);
searchresult(response);
}
});
});
});
let searchresult = function(response) {
let container = document.getElementById('VGFresults');
let output = "";
for (let j = 0; j < response.length; j++) {
if (response[j].rcode == "VGF") {
output +=
`<div id="person${response[j].code}">
<p>${response[j].firstname} ${response[j].lastname}</p>
</div>`
}
$(container).html(output);
}
};
Here is my response (Same layout as I am currently receiving but shortened the objects in the arrays).
response =
{"VGF":
[{"code":"TU","rcode":"VGF","firstname":"Tom","lastname":"Riddle"},
{"code":"AZ","rcode":"VGF","firstname":"Harry","lastname":"Potter"},
{"code":"FR","rcode":"VGF","firstname":"Hermoine","lastname":"Granger"}],
"SSR":
[{"code":"HG","rcode":"SSR","firstname":"Walt","lastname":"Disney"},
{"code":"TR","rcode":"SSR","firstname":"H.R.","lastname":"Pickins"},
{"code":"ED","rcode":"SSR","firstname":"Tom","lastname":"Ford"}],
"BCV":
[{"code":"YH","rcode":"BCV","firstname":"Tom","lastname":"Clancy"},
{"code":"RS","rcode":"BCV","firstname":"Robin","lastname":"Williams"},
{"code":"AB","rcode":"BCV","firstname":"Brett","lastname":"Favre"}]}
Here is the HTML that the searchresult function is working with. Currently, it works fine.
To clarify, I would like each object to insert its arrays within the corresponding div. Example:
SSR arrays will go into <div id="SSRresults">
BCV arrays will go into <div id="BCVresults">
From there, each array will create a div within that *results div for each array.
<div id="VGFresults">
<div id="VGFheader">This is the VGF Header</div>
<div id="VGFresults">The Javascript Creates Divs for each array here.</div>
</div>
<div id="SSRresults">
<div id="SSRheader">This is the SSR Header</div>
<div id="SSRresults">The Javascript Creates Divs for each array here.</div>
</div>
<div id="BCVresults">
<div id="BCVheader">This is the BCV Header</div>
<div id="BCVresults">The Javascript Creates Divs for each array here.</div>
</div>
Thanks, any help is much appreciated.
I would do like this:
I declare the response as variable (but sure it will work with your ajax response.
var response =
{"VGF":
[{"code":"TU","rcode":"VGF","firstname":"Tom","lastname":"Riddle"},
{"code":"AZ","rcode":"VGF","firstname":"Harry","lastname":"Potter"},
{"code":"FR","rcode":"VGF","firstname":"Hermoine","lastname":"Granger"}],
"SSR":
[{"code":"HG","rcode":"SSR","firstname":"Walt","lastname":"Disney"},
{"code":"TR","rcode":"SSR","firstname":"H.R.","lastname":"Pickins"},
{"code":"ED","rcode":"SSR","firstname":"Tom","lastname":"Ford"}],
"BCV":
[{"code":"YH","rcode":"BCV","firstname":"Tom","lastname":"Clancy"},
{"code":"RS","rcode":"BCV","firstname":"Robin","lastname":"Williams"},
{"code":"AB","rcode":"BCV","firstname":"Brett","lastname":"Favre"}]}
let searchresult = function(response) {
// let container = document.getElementById('VGFresults');
let output = "";
for (var key in response) {
// skip loop if the property is from prototype
if (!response.hasOwnProperty(key)) continue;
var obj = response[key];
let container = document.getElementById(key+'results');
for (var prop in obj) {
// skip loop if the property is from prototype
if (!obj.hasOwnProperty(prop)) continue;
// your code
//alert(prop + " = " + obj[prop]);
console.log(obj[prop])
output += "<div id="+prop+"><p>"+obj[prop].firstname+" "+ obj[prop].lastname+"</p></div>"
}
}
container.innerText = output;
console.log(output);
};
<div id="VGFresults"></div>
each property VGF, SSR, BCV and so on can be handled now.
EDIT: based on users request, I guess you can edit the selector like this:
let container = document.getElementById(key+'results');
I am completely new to angular js and am trying to build a google map widget in Service Portal within ServiceNow that dynamically shows the user's job location. I have a server script that pulls and formats the location:
var gr = new GlideRecord('cmn_location');
gr.addQuery('sys_id', gs.getUser().getLocation());
gr.query();
if(gr.next())
{
var loc = gr.street.getHTMLValue();
}
loc1 = loc.replace(/,/g, "");
loc2 = loc1.replace(/ /g, "+");
data.src = loc2;
And my HTML looks like this:
<div class = "map-container">
<iframe ng-src='https://www.google.com/maps/embed/v1/place?key=AIzaSyCmoLpiJFrdXLLUYsM3PRfPD0zQ0uATAUw&q={{data.src}}'></iframe>
</div>
The iframe and {{data.src}} do not work together. If I take away the iframe portion of the code and replace it with {{data.src}}, the address loads correctly. Also, if I replace {{data.src}} with a real address (i.e. washington+dc), the map shows Washington DC correctly.
Can someone help me troubleshoot this issue?
Thanks!
You can have a function defined in the controller and pass the url to it,
routerApp.controller('AppCtrl', ['$scope','$sce', function($scope,$sce) {
$scope.trustSrc = function(src) {
return $sce.trustAsResourceUrl(src);
}
HTML
<iframe ng-src="{{trustSrc(https://www.google.com/maps/embed/v1/place?key=AIzaSyCmoLpiJFrdXLLUYsM3PRfPD0zQ0uATAUw&q={{data.src}})}}'></iframe>

I am trying to create a simple bar chart, but when appending the bars to the DOM I get this error
Object [object Object] has no method 'appendChild'
$rootScope.drawChart = function (data,selector,padding){
var max = Math.max.apply(Math, data);
var chart = angular.element(document.getElementById("chartxx"));
var barwidth = ((chart.offsetWidth-(data.length-1)*padding-(data.length)*10)/data.length);
var sum = data.reduce(function(pv, cv) { return pv + cv; }, 0);
var left = 0;
for (var i in data){
var newbar = document.createElement('div');
newbar.setAttribute("class", "bar");
newbar.style.width=barwidth+"px";
newbar.style.height=((data[i]/max)*100)+"%";
newbar.style.left=left+"px";
console.log(chart);
angular.element(document.getElementById("chartxx")).appendChild(newbar);
left += (barwidth+padding+10);
}
}
var values = [85,95,120,100,200,200,230,230,60,320,23,3433,434,45,23,23];
$rootScope.drawChart(values,"#chartxx2",5);
<div class="wrapperx2">
<div id="chartxx"></div>
</div>
appendChild() is a method inherent to native HTML objects, aka the result of document.getElementById. When you give that HTML object to angular.element it becomes a jQuery Object. jQuery objects have a similar method called append()
So you can do document.getElementById("chartxx").appendChild(newbar) or angular.element(document.getElementById("chartxxx")).append(newbar).
So that should answer your question but I can't help but ask myself : why would you do something like that when you're using AngularJS ?
Edit
Ok so here's a very poorly achieved version of what I would have done in your place (if I was ABSOLUTELY unable to use an external library, because using an external library for charts is what I would normally do). I suggest you see and try to understand how the ng-repeat works here and try to apply it to your case.
angular.element doesn't contain method appendChild
angular.element doc
You can try:
chart.append(newbar);
I am an angular newbie and I study the book "Angular JS by example" and I try to create my own filter. (pp. 93-94).
In my controller this is the string I want to manipulate
procedure: "Assume a position, with feet together .\Slightly bend your knees, .\While in air, bring your legs out .\ As you are moving your legs outward"
and then I sanitise it
$scope.trustedHtml = $sce.trustAsHtml($scope.currentExercise.details.procedure);
Since this is an SPA , the filter is in the description-panel.ejs file, that is inside workout.ejs, that is inside index.ejs
description-panel.ejs has
<div class="panel-body" ng-bind-html ="trustedHtml | myLineBreakFilter"> </div>
workout.ejs has
<div id="video-panel" class="col-sm-3" ng-include="'description-panel.ejs'">
and index.ejs has
<script src="/javascripts/7MinWorkout/filters.js"></script>
filter.js has the filter
angular.module('7minWorkout').filter('myLineBreakFilter', function () {
return function (input) {
var str = input;
var br = "</br></br>";
var position = str.indexOf(".");
var output = [str.slice(0, position), br, str.slice(position)].join('');
return output ;
}
});
The filter should replace all the . with </br></br>.
This does not work and I get no text at all in my front-end. I get this error in the console
TypeError: str.slice is not a function at filters.js:22
Shouldn't basic js stuff like str.slice be supported out of the box? What am I missing?
Thanks
$sce.trustAsHtml() return you an object so slice will not work on it.You can pass that object to $sce.getTrustedHtml(object) to obtain the original value and then can apply slice on it.
angular.module('7minWorkout').filter('myLineBreakFilter', function ($sce) {
return function (input) {
var str = $sce.getTrustedHtml(input);
var br = "</br></br>";
var position = str.indexOf(".");
var output = [str.slice(0, position), br, str.slice(position)].join('');
return $sce.trustAsHtml(output) ;
}
});
Try this add this before the splice
str.toString();
str.splice(//pass parameters);
In my data object I have a full YouTube URL (http://www.youtube.com/watch?v=kJ9g_-p3dLA).
In my partial I need to extract the video ID from this string (kJ9g_-p3dLA). I'm trying not to resort to running through all my data when the app starts and extracting the video ID through that way.
I'm looking for a filter or a directive that I can feed the full YouTube ID to which will return the video ID. Anyone?
Ended up writing my own filter for this:
app.filter("GetYouTubeID", function ($sce) {
return function (text) {
var video_id = text.split('v=')[1].split('&')[0];
return video_id;
}
})
Can be used in a partial like so:
{{content.complete_youtube_url | GetYouTubeID}}
<button onclick="myFunction()">Try it</button>
<p id = "demo" />
<script>
function myFunction() {
var url= "http://www.youtube.com/watch?v=kJ9g_-p3dLA"; //sample url
var res = str.split("http://www.youtube.com/watch?").splice("1");
document.getElementById("demo").innerHTML = url;
}
</script>
You could use regular expressions, which have no dependencies on Angular.
Note that I'm not a regex expert so my expression may not be perfect.
var regex = new RegExp(/(?:\?v=)([^&]+)(?:\&)*/);
var url = "http://www.youtube.com/watch?v=kJ9g_-p3dLA";
var matches = regex.exec(url);
var videoId = matches[1]; // kJ9g_-p3dLA
That regex will capture a group between ?v= and & (the & is optional).
Test with explode function of PHP
$youtubre_url = "http://www.youtube.com/watch?v=kJ9g_-p3dLA";
$array_id = explode("=",$youtubre_url);
$id = $array_id[1];
