Fill html-table data with jquery fails Uncaught ReferenceError
2
I would like to use jquery in Angular to create a table based on my data input. I am new to jquery, so this might be some dumb thing I forgot, but I cannot say what it is.
Sadly when I execute ng serve what happens is nothing, just a blank page.
I got the following code:
HTML
<body onLoad="createHeaders('#dataTable')">
<table #dataTable >
</table>
</body>
TS
import { Component, OnInit } from '@angular/core';
import { MOCKUP } from '../Table';
import * as $ from "jquery";
@Component({
selector: 'app-tabular',
templateUrl: './tabular.component.html',
styleUrls: ['./tabular.component.css']
})
export class TabularComponent implements OnInit {
constructor() { }
ngOnInit() {
}
//this is where i want to work in the future, lets just forget about that for the moment
buildHTMLTableCodeFromTree(selector) {
//var header = this.createHeaders(selector, MOCKUP.Head);
$(selector).append("<td>test</td>");
}
createHeaders(selector) {
var headObject = MOCKUP.Head;
console.log("Er ist in der Methode!");
var value;
var colspan;
var entry = "";
for (var j = 0; j < headObject.length; j++) {
entry = entry + "<tr>";
for (var i = 0; i < headObject[j].length; i++) {
value = headObject[j][i].value;
colspan = headObject[j][i].colspan;
entry = entry + "<th colSpan='" + colspan + "'>" + value + "</th>";
}
entry = entry + "</tr>";
}
$("dataTable").append(entry);
}
}
The table Head Mockup:
export const MOCKUP = {
"Table": "tab1",
"Head": [
[
{
"value": "",
"colspan": 1,
},
{
"value": "2018",

{

},
{
"value": "Boo",

}
]
],
"Body": [
[
{
"value": "Total",
"entryID": -1
},
{
"value": "10",
"entryID": 33
},
{
"value": "24",

{

"entryID": 38
},
{
"value": "21",
"entryID": 39
},
{

}
],
[

{

{

}
]
]
}
I wanted it to be a three-rowed header (Year, Month and the last row out of the last values of my HEAD-array). I've tried to do it according to
I also tried to do it like described here (so with $("#dataTable").append(entry); but that does not change the outcome.
Edit: Indeed there is an error, not in the command prompt where ng serve is executed, but in the Chrome-console:
Uncaught ReferenceError: createHeaders is not defined
at onload (localhost/:13)
Obviously he did not instantiate the method when executing the HTML-Code.
Edit: Why am I trying with jquery?
Note: This might not be necessary for the question itself, it is meant as an explanation
Here's an example of my data:
and the desired output:
Now the output has to be editable and these edits should be saved in my database (on button click, that's why I saved the entryID in my mockup).
For the communication from Backend->Frontend I thought about the above format of the raw data (that's why I save an entryID):

why do you want to use jquery to manipulate the DOM in angular?

@L.A I edited my question and tried to explain what and why I am trying to do it that way. If you have another possibility feel free to tell me :) (I know you shouldn't ask for these things in a question, still I am open for other ideas)

If you want something really fast, however, it's best to do without jQuery and reuse as much of the objects you generate as possible.

If you want something really fast, however, it's best to do without jQuery and reuse as much of the objects you generate as possible.
<table id="dataTable"></table>

function render(target, data) {

@L.A I edited my question and tried to explain what and why I am trying to do it that way. If you have another possibility feel free to tell me :) (I know you shouldn't ask for these things in a question, still I am open for other ideas)
