I have the following code in my html document:
<div *ngFor="let search of this.mySearches; let i = index" class="col-sm-6 col-xs-12">
<div class="box">
<div class="image img-search-rounded">
<img [src]="search.postPath | imagenpost: search.generic_category: search.postImg[0]" alt="image" title="image" id="img-rounded" class="img-responsive img-rounded">
</div>
<div class="pull-left">
<h4>{{search.generic_category}}<i class="la la-angle-double-right"></i>{{search.generic_type}}</h4>
<p><i class="la la-map-marker"></i>{{search.generic_city}}</p>
<p><i class="la la-clock-o"></i> {{search.date | date:'medium'}}</p>
<p><i class="la la-circle"></i> Get email notifications</p>
</div>
<div class="pull-right">
<button type="button" [routerLink]="search.url">View</button>
<button type="button" (click)="removeMySearch(search._id)">Delete</button>
</div>
</div>
</div>
but I get this and not the image:
How could I render the image?
It's not quite clear what you're trying to do. It seems like you are trying to do an OR using a ternary operator, but you are missing the else part.
The condition should be something like
<div [ngStyle]="{'background-color':person.country === 'UK' ? 'green'
> : 'red' }"></<div>

i want use custom js variable to get card-title a shop-item-title-link's text for the event label = "product x".
Clicking the click class fa-cart-plus to get the label product x;
Click the image to get the label product x
I've tried this js below, but it gets [object] [object] as the result.
function() {
var el = {{Click Element}};
return $(el).closest('card-title').text('a.shop-item-title-link');
}
HTML
<div class="card card-product">
<div class="card-image">
<a href="#" title="product x">
<img width="230" height="230" src="#" class="attachment-_thumbnail" alt="product x">
</a>
<div class="ripple-container"></div>
</div>
<div class="content">
<h6 class="category">Items</h6>
<h4 class="card-title">
<a class="shop-item-title-link" href="#" title="product x">product x</a>
</h4>
<div class="card-description">
<p><span>product descirption</span></p>
</div>
<div class="footer">
<div class="price">
<h4><span class="Price"><span class="Price-currencySymbol">£</span>45.00</span></h4>
</div>
<div class="stats">
<a rel="nofollow" href="#" title="Add to cart">
<i rel="tooltip" data-original-title="Add to cart" class="fa fa-cart-plus"></i>
</a>
</div>
</div>
</div>
</div>
That is a very specific target, what you want to do is use parent and sibling together.
Try something like this:
return $(el).parents().siblings('.card-title').text();

After deleting the item from array, I am trying to update the object like this:
this.products = (this.products.filter(e => e != (data['products'].id)))
It seems so that your view does not check the changes of your products array.
So I would say trigger it manually:
InjectChangeDetectorRef to trigger change detection manually.
constructor(private cd: ChangeDetectorRef){....}
And in your method call this.cd.detectChanges():
async deleteProduct(e) {
...
data['success'] ? this.products = (this.products.filter(e => e != (data['products'].id))) : this.data.error(data['message']);
this.cd.detectChanges();
...
}
you are comparing e to != e['products'].id ..
it is not true.
i think you should be checking the variable which holds the id in your "e"
which means
e.id != ...or something like so.
I Hope it is working.
I am building a web App using Angular 2 and want to loop the button with the list items but outside of list items, how can I get the functionality using *ngFor, please help.
My HTML code:
<div class="col-xs-6">
<a class="list-group-item clearfix" style="background-color:rgb(3, 0, 48)" *ngFor="let buying of buy">
<div class="pull-left" style="max-width:350px">
<h5 style="color:white">{{buying.names}}</h5>
<p style="color:white">{{buying.desc}}</p>
</div>
<div>
<span class="pull-right" >
<img [src]="buying.getImg" alt="image not loaded" class="img-responsive" style="max-height:100px">
</span>
</div>
</a>
</div>
<div class="col-xs-6"> <-----I WANT TO LOOP THIS BUTTON
<button class="btn btn-primary ; pull-right">Add To Cart</button>
</div>
Try this code snippet. I have created a div tag above linking both content and then added the loop inside that, so it will refer to both elements (item and button).
<div *ngFor="let buying of buy">
<div class="col-xs-6">
<a class="list-group-item clearfix" style="background-color:rgb(3, 0, 48)">
<div class="pull-left" style="max-width:350px">
<h5 style="color:white">{{buying.names}}</h5>
<p style="color:white">{{buying.desc}}</p>
</div>
<div>
<span class="pull-right">
<img [src]="buying.getImg" alt="image not loaded" class="img-responsive" style="max-height:100px">
</span>
</div>
</a>
</div>
<div class="col-xs-6">
<button class="btn btn-primary ; pull-right">Add To Cart</button>
</div>
</div>
repeat in my code
<div class="feed-element"ng-repeat="message in messages">
<a href="" class="pull-left">
<img alt="image" class="img-circle" src="{{message.src}}"onerror="this.src='https://cdn2.iconfinder.com/data/icons/transparent-round-icons/512/user.png';">
</a>
<div class="media-body ">
<small class="pull-right"></small>
<strong> {{message.User}} <br>
<small class="text-muted">{{message.Date}}</small>
<div class="well">
{{message.Question}}
</div>
<div class="pull-right">
<div class="well"style="display:{{message.isAnswered}}">{{message.Answer}}</div>
<div class="social-comment"style="display:{{message.isAnswered2}}">
<div class="media-body">
<textarea class="form-control" placeholder="Cevap Yazın..."></textarea>
</div>
</div><br>
<a class="btn btn-xs btn-primary"style="display:{{message.isAnswered2}};width:150px;" ng-click="answer(message.Id)"><i class="fa fa-pencil"></i> Mesaj Gönder</a>
</div>
</div>
</div>
In This code , every message has textarea and a button and every message is unique to any user so when I click one button I want to get text of that's item textarea only, But I couldn't do it how can I do it?
Thanks
Replace your textarea as below ,
yourtextareavalue should be your key name to bind values
<textarea class="form-control" ng-model="message.yourTextAreaValue"
placeholder="Cevap Yazın..."></textarea>
I am trying to find clicked button value.here is my htmlcode,I am not able to get but always getting first one.

I tried following code in jquery
$(".dialogs .itemdiv .tools").live("click",function(e){
e.preventDefault();
alert('clicked on edit');
var n = $('.dialogs .itemdiv .tools a').attr('id');
alert(n);
});
I use live here because I am getting above html by using append method in jquery.
live is deprecated in later versions of jQuery - but to solve your issue you need to use an instance of this
$("#addSentiment").on("click", ".dialogs .itemdiv .tools", function(e){
e.preventDefault();
alert('clicked on edit');
var n = $("a", this).attr('id');
alert(n);
});
jQuery selectors catch the first match of their content.
To catch the n-th match, you need to use the n-th child selector, like this:
$(".dialogs .itemdiv .tools:nth-child(2)")
I am not familiar with the live method, but you should be able to do something like the following:
function addHandlers() {
$(".dialogs .itemdiv .tools a").each(function() {
$(this).click(function() {
alert('clicked on edit');
);
});
}
function yourAppendFunction() {
//your append code
//add call to a function that will create your event handlers
addHandlers();
}
The .each method runs through each and every item that fits the selection criteria, and then we use the this keyword within the function to reference what we are working on. Putting it in a function that we don't call until after you append the items ensures the html exists when you try to add the handlers you need.
