Applying ng-click to a table column - html

Is it possible to apply ng-click in AngularJS to a table column? I tried the following, which doesn't seem to do the trick.
<table>
<colgroup>
<col ng-repeat="item in items" ng-click="myFunction(item)"> </col>
</colgroup>
<thead>
<tr>
<th ng-repeat="item in items"> {{item.title}} </th>
</tr>
</thead>
<tbody>
<tr>
<td ng-repeat="item in items"> {{item.info}} </td>
</tr>
</tbody>
</table>

It is not possible do it in the way you have tried. You may register the ng-click on every td element. Another possibility may be registering the ng-click at the table element and use the original dom event to determin wich column was clicked. You can access the event in this way: ng-click="myFunction($event)" then in the controler:
$scope.myFunction = function(e){
console.log(e);
}

How to pass the id of one div element to another provided second being executed in loop?

I have two div elements and my requirement is how do I pass the id of present in second div element and is getting executed in the loop to the first div element button. Here is the sample code :
<div style="float: right;">
<button type="button" (click)="delete(skillGroupAndTypeRow.id);"></button>
</div>
<table class="table table-bordered">
<thead>
<tr>
<th>Select</th>
<th>Skill Group Names</th>
<th>Skill Type</th>
</tr>
</thead>
<tbody>
<tr #skillGroupAndTypeRow *ngFor="let group of groups; let i=index;" id="skillRow-{{i}}">
<td>
<input type="checkbox" id="group-{{i}}" >
</td>
<td>{{group.name}}</td>
<td>{{group.type}}</td>
</tr>
</tbody>
</table>
So how do I pass the Id of tag into the delete button present in above div.
With this approach there is a error saying cannot read id of undefined.

How to dynamically add HTML element/content - Angular

What would be the best way to dynamically add an HTML element, such as another column onto a basic HTML table?
I want to have a button below the table, and if the user were to click the button, the event would add the same amount of rows already in the table and add another column. I would want to support about 5 extra columns being added to the table.
Here's my HTML table as of right now:
<table>
<thead>
<tr>
<th id="row-tag"></th>
<th id="option-column">Option 1</th>
</tr>
</thead>
<tbody>
<tr>
<td id="row-tag">P</td>
<td id="option-column">{{ p }}</td>
</tr>
<tr id="row-tag">
<td>
<app-a-p (saveButtonClick)="toggleAP($event)"
[modModalValues]="modModalValues">
</app-a-p>
</td>
<td id="option-column">
<div class="input-group input-group-sm">
$<input
*ngIf="toggleAP==true"
type="text"
name="aP"
size="10"
disabled
value=""
/>
<input
*ngIf="toggleAP==false"
type="text"
name="aP"
size="10"
[ngModel]="con.pA"
(ngModelChange)="con.pA = $event" appFormatP
(blur)="checkAP($event.target.value);
inputTracker.addModifiedValue('Option 1', $event.target.value)"
/>
</div>
</td>
</tr>
<tr>
<td id="row-tag">L</td>
<td id="option-column">${{l}}</td>
</tr>
<tr>
<td id="row-tag">R</td>
<td id="option-column">${{r}}</td>
</tr>
</tbody>
</table>
I think in Angular, you define table based on your data. for example, you have fields array defining columns, and data array defines the what's actually in the table.
<table >
<thead>
<tr>
<th *ngFor='let key of this.fields'>{{key}}</th>
</tr>
</thead>
<tbody>
<tr *ngFor='let row of this.data ' >
<td scope="row" *ngFor='let key of this.fields'> {{row[key]}} </td>
</tr>
</tbody>
</table>
when you need a new column, just push a new field into fields. like
fields.push('newcolumn');
when you need a new row, just do:
data.push({col1: '', col2:'', newcolumn: ''});
Look into the insertRow() and insertCell() functions in JavaScript. This alongside an onClick function that you write will let you edit the table.
A good way of generating a table on UI when using angular would be to use 2D-array (row*column) use can have a button using which you can dynamically add values to this array and have another row/column to the table.

Filling all input fields

There is a markup:
<div class="scroll">
<table class="table table-striped">
<thead>
<tr>
<th>Image</th>
<th>Name</th>
<th>Author</th>
<th>Year</th>
<th>ISBN</th>
<th>Price</th>
<th>Count</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let book of bookService.bookList">
<td><img src="../../{{book.ImagePath}}" width="100" height="150"></td>
<td>{{book.Name}}</td>
<td>{{book.Author}}</td>
<td>{{book.Year}}</td>
<td>{{book.ISBN}}</td>
<td>{{book.Price}}</td>
<td>{{book.Count}}</td>
<td>
<input type="text" name="Count" [(ngModel)]="Count">
<button class="btn btn-block btn-outline-success" (click)="onAdd(book, Count)"><i class="fa fa-plus"></i></button>
</td>
</tr>
</tbody>
The last column looks like this:
The problem is the following: when filling one TextBox, all the TextBoxes in the column are filled.
How can I solve this problem? Tried to give unique names to text fields and to thrust this cell in form, but all the same did not work.
You need to give unique name to the input field using angular template
<input [name]="'count' + i" >
Where i is the index from the *ngFor
But I think the major issue you have is that you need to bind book.Count instead of just Count
In latter case you'll have one variable called Count and you bind the same variable to all of the input fields. You need to attach the variable to the book itself so it is unique.
All your inputs have the same [(ngModel)]="Count" and the same name so if you update one, all of them will be updated
You can fix that if you have an array of count instead. So it will be something like
<tr *ngFor="let book of bookService.bookList; let i = index">
...
<input type="text" [name]="'count' + i" [(ngModel)]="count[i]">
People are giving you the HTML way, I'm giving you the Angular way : trackBy functions.
*ngFor="let book of bookService.bookList; trackBy: book.Name"
This one should work but I've never tested it.
The one should work in any case :
*ngFor="let book of bookService.bookList; trackBy: customTB"
customTB(item, index) {
return `${index}-${item.Name}`;
}
You can't use the same name for your inputs.
To fix this, you can add an id populate by the index of the loop *ngFor
Try this :
<tr *ngFor="let book of bookService.bookList; let i = index">
<input type="text" name="Count_${i}" [(ngModel)]="count">

Zebra-strip for tables using ng-repeat

I am display large set of data content in table using ng-repeat and it contains only one <tr> element. I am trying to display odd row in one color and even row in another color. I am not getting how to display the striped color for single row by making use of ng-repeat. Please let me know where I am going wrong.
HTML:
<thead class="rowhead">
<tr>
<th class="mid">Sl.</th>
<th id="tnm">Name</th>
<th class="mid">Age</th>
<th class="mid">Members</th>
<th class="mid">View-content</th>
<th class="mid">on-going-Process</th>
</tr>
</thead>
<tbody ng-repeat="info in cspinfo">
<tr class="clr">
<td>{{$index+1}}</td>
<td id="bnm">{{info.name}}</td>
<td>{{info.age}}</td>
<td>{{info.member}}</td>
<td>{{info.View-content}}</td>
<td>{{on-going-Process}}</td>
</tr>
</tbody>
You can directly select the odd and even rows of table using the selector in css and apply style you need. You don't have to worry about the applying class to each row you create using ng-repeat.
tr:nth-child(odd){
background-color: #yourcolor
}
tr:nth-child(even){
background-color: #yourcolor
}
Here you can read more about css selectors https://developer.mozilla.org/en-US/docs/Web/CSS/%3Anth-child
In your css define a rule for the style. Then in your html:
<tbody>
<tr class="clr" ng-class="{style-created: $index % 2 === 0}" ng-repeat="info in cspinfo">
<td>{{$index+1}}</td>
<td id="bnm">{{info.name}}</td>
<td>{{info.age}}</td>
<td>{{info.member}}</td>
<td>{{info.View-content}}</td>
<td>{{on-going-Process}}</td>
</tr>
</tbody>

Vertical table with dynamic data

Seems to be the same requirement like AngularJS "Vertical" ng-repeat but solution doesn't work for *ngFor
I have this object array that I am trying to bind to an HTML table. Its format is something like below:
[
{
"Animal":"Dog",
"Country":"France",
"Food":"Tofu",
"Car":"Nano",
"Language":"TypeScript"
}
]
Now this can simply be formatted in the default HTML horizontal table way like this:
<table>
<tr>
<th>Animal</th>
<th>Country</th>
<th>Food</th>
<th>Car</th>
<th>Language</th>
</tr>
<tr *ngFor="let data of datas">
<td>{{data.Animal}}</td>
<td>{{data.Country}}</td>
<td>{{data.Food}}</td>
<td>{{data.Car}}</td>
<td>{{data.Language}}</td>
</tr>
</table>
This would create table like below(Please ignore the data in the table;its just to give an idea.):
But how would I create a structure like this with dynamic data(kind of a vertical table):
In Component:
this.arrayOfKeys = Object.keys(this.datas[0]);
html:
<table>
<tr *ngFor="let key of arrayOfKeys">
<th>{{key}}</th>
<td *ngFor="let data of datas">
{{data[key]}}
</td>
</tr>
</table>
Use ng-container if You have data structure similar to groups[].items[].name
So, if You want to add row
<table>
<ng-container *ngFor="let group of groups">
<tr>
<td>{{group.name}}</td>
</tr>
<tr *ngFor="let item of group.items">
<td>{{item.name}}</td>
</tr>
</ng-container>
</table>
