Below is what I have tried, when I hit enter after adding value in input field, I see just Gardening and Painting but but does not show the new values I enter.
Please help me understand what am I doing wrong here..
template file:
<div formArrayName="hobbies">
<h4>Your Hobbies</h4>
<input type="text" class="form-group" (keyup.enter)="onAddHobby()">
<ul class="list-group">
<li *ngFor="let hobby of signUpForm.get('hobbies')['controls'];let i=index"
class="list-group-item">{{hobby.value}}</li>
</ul>
</div>
typescript file:
ngOnIt{
'hobbies': new FormArray([new FormControl('Gardening'), new FormControl('Painting')])
}
onAddHobby(){
const control= new FormControl('', Validators.required);
(<FormArray>this.signUpForm.get('hobbies')).push(control);
}
Because in onAddHobby() method, you are pushing empty formcontrol in every time when you hit enter. Receive the value from the event and pass it to formControl something looks like,
In Html,
(keyup.enter)="onAddHobby($event.target.value)"
In Ts,
onAddHobby(value){
const control= new FormControl(value, Validators.required);
(<FormArray>this.signUpForm.get('hobbies')).push(control);
}

I make a draft implementation for my reusable input component.
The code below obviously throws an error.
Question is how to pass the $event back to register blade to get or log the value of the input?
register.blade.php
<div>
<x-input onChange="(value) => {console.log('value', value)}"></x-input>
<div/>
input.blade.php
#props(['onChange' => 'null'])
<input x-on:change="{{ $onChange($event) }}">
A few things here.
First off, your markup is wrong. You have a the closing slash at the wrong end of the closing div. Should be </div> not <div/>.
Then you're using x-on without x-data. Alpine only picks up components with the x-data attribute.
Finally, events propagate automatically, so you could just listen on the parent instead:
{{-- register.blade.php --}}
<div x-data>
<x-input x-on:change="console.log('value', $event.target.value)" />
</div>
{{-- input.blade.php --}}
<input {{ $attributes }}>
I learned we could just achieve this through Alpine.Js dispatch. I don't need to pass onClick props via Laravel component. I just simply use dispatch to listen the event (x-on).
What I like in this implementation is that,
aside of event information, passing of extra data is easy
you don't have to use Laravel props and assigned unnecessary props in the tag.
register.blade.php
<div>
<x-input x-on:custom-input="console.log('your values =', $event.target.newValue)"
></x-input>
<div/>
input.blade.php
<input x-on:change="$dispatch('custom-input', { newValue: $event.target.value })">
you can pass "key" prop to distinguish each component.
I want to add an item in cart with a matching text like 'cashews'. I tried below code but .click() function is giving error as "bind and event handler to the click javascript event"
cy.get('.products').find('.product').each(($e1, index, $list) => {
const textveg = $e1.find('h4.product-name').text() {
if (textveg.includes('Cashews')) {
$e1.find('.button').click();
}
}
})
can someone suggest what can be the possible reason that .click() method is not identified by cypress. I am using cypress version 7
How you do this depends on the structure of the HTML.
It looks like you may have this sort of hierarchy
<div class="products">
<div class="product">
<h4 class="product-name">Almonds</h4>
<button>Add to cart</button>
</div>
<div class="product">
<h4 class="product-name">Cashews</h4>
<button>Add to cart</button>
</div>
</div>
Take the product section containing the text you want, and within that find the products <button>.
Your test might be
cy.contains('.product', 'Cashews') // pick the <div class="product"> with required text
.find('button') // inside the product, find it's button
.click()
You can use .filter() to find your element and click it:
cy.get('h4.product-name').filter(':contains("Cashews")').click()
What is the proper way to edit items in a listview when using Kendo UI Mobile & MVVM?
I don't get the expected results when using the following:
HTML
<div id="itemsView"
data-role="view"
data-model="vm">
<ul data-role="listview" data-bind="source: items"
data-template="itemsTemplate">
</ul>
<script id="itemsTemplate" type="text/x-kendo-template">
<li>
#=Name#
</li>
</script>
<input type="text" data-bind="value: newValue" />
<button data-role="button" data-bind="click: update">update</button>
</div>
JavaScript
var vm = kendo.observable({
items: [{
Name: "Item1"}],
newValue: '',
update: function(e) {
var item = this.get("items")[0];
item.set("Name", this.get("newValue"));
//adding the follwoing line makes it work as expected
kendo.bind($('#itemsView'), vm);
}
});
kendoApp = new kendo.mobile.Application(document.body, {
transition: "slide"});
I expect the listview to reflect the change to the Name property of that item. Instead, a new item is added to the listview. Examining the array reveals that there is no additional item, and that the change was made. (re)Binding the view to the view-model updates the list to reflect the change. Re-Binding after a change like this doesn't seem to make any sense.
Here is the jsfiddle:

Not sure if I understand your question properly: but this is how I did something similar with Kendo Web UI, I expect mobile is not so different from Web UI from API perspective.
$element.kendoListView({
dataSource: list,
template: idt,
editTemplate: iet,
autoBind: true
});
The way I bind the listview is different, but I guess you can get similar results with your method as well.
I pass two templates to the list view, one for displaying and one for editing.
Display template contains a button (or any element) with css class k-edit to which kendo will automatically bind the listview edit action.
display template:
<div class="item">
# if (city) { #
#: city #<br />
# } #
# if (postCode) { #
#: postCode #<br />
# } #
<div class="btn">
<span class="k-icon k-edit"></span>Edit
<span class="k-icon k-delete"></span>Delete
</div>
</div>
Edit template
<div class="item editable">
<div>City</div>
<div>
<input type="text" data-bind="value: city" name="city" required="required" validationmessage="*" />
<span data-for="city" class="k-invalid-msg"></span>
</div>
<div>Post Code</div>
<div>
<input type="text" data-bind="value: postCode" name="postCode" required="required" validationmessage="*" />
<span data-for="postCode" class="k-invalid-msg"></span>
</div>
<div class="btn">
<span class="k-icon k-update"></span>Save
<span class="k-icon k-cancel"></span>Cancel
</div>
</div>
Clicking that element will put the current element on edit mode using the editTemplate.
Then on the editTemplate there is another button with k-update class, again to which kendo will automatically bind and call the save method on the data source.
Hopefully this will give you more ideas on how to solve your issue.
The problem was caused by the <li> in the template. The widget already supplies the <li> so the additional <li> messes up the rendering. This question was answered by Petyo in the kendo ui forums
Hi there I have an error when I submit the following form:
<div id="tabs">
<ul>
<li>Project Details</li>
<li>Project Attachments</li>
<li><a href="#Url.Action("Members", "ProjectNetwork", new { IsTab = true })">Project
Network</a></li>
<li>Bulleting Board</li>
<li>Bids Received</li>
</ul>
</div>
<div id="LowerButton">
#Html.Hidden("MainStatus", #Model.Status)
#using (#Html.BeginForm("Dashboard", "Dashboard"))
{
<button type="button" id="MakeComment">
Make a Comment
</button>
<input type="submit" id="GoDashBoard" value="Return to Project List" />
}
</div>
When I press the button "GoDashBoard", The method "Dashboard" in the controller "Dashboard" is not reached. Instead the following error appears:
It tells me that a model property is beign sent to the server. However, there are no model properties inside the dashboard form.. unless I'm sending many forms at the same time. But I dont think thats possible right? Do you guys have any idea of why is trying to set a model property when I'm not actually sending any?
Update:
this is the input of the dashboard action:
public ActionResult Dashboard(int page = 1)
{
var user = (User)Session["User"];
if (user != null)
{...
}}
the input is a default integer. However, I saw the trace of the calls and its submiting another form which is not related to the one im using:
That form is inside of one of the ajax tabs. I dont understand how one form submits another form and they are not nested. Anyone knows a good workaround? because im thinking of receiving both forms in both actions and make some validations.
I solved it by removing the form "Dashboard" and instead adding an invisible link. The button would reference the invisible link:
#*#using (#Html.BeginForm("Dashboard", "Dashboard"))
{ *#
<button type="button" id="MakeComment">
Make a Comment
</button>
<button name="button" type="button" onclick="document.location.href=$('#GoDashBoard').attr('href')">Return to Project List</button>
<a id="GoDashBoard" href="#Url.Action("Dashboard", "Dashboard")" style="display:none;"></a>
#*<input type="submit" id="GoDashBoard" value="Return to Project List" />*#
#* }*#
I have the form and some code below.
#using (Html.BeginForm("Insert", "Question", "POST"))
{
<div id="add_tag">
<div id="list_tag">
<span class="post-tag" id="2">Phi kim<span class="delete-tag" title="Xóa Tag này"></span></span>
<span class="post-tag" id="22">Hóa Vô Cơ<span class="delete-tag" title="Xóa Tag này"></span></span>
<span class="post-tag" id="1">Lý<span class="delete-tag" title="Xóa Tag này"></span></span>
</div>
<div class="tag-suggestions hidden">
</div>
</div>
<div class="form-sumit clear">
<input type="submit" id="submit-button" value="Post your question" />
</div>
}
And my Insert action in QuestionController like this
[HttpPost]
[ValidateInput(false)]
public ActionResult Insert(FormCollection _form)
{
//my code here
}
I want to get id of span tag nested in by using Html.BeginForm and FormCollection. How can I do that? Plz someone help me. Thanks a lot.
When you click on submit button, form collects all input values inside this form and send to the server with the following format: inputId=inputValue. Span isn't the input control inside the form and form does not collect its value or another information to send to the server. You can generate hidden input control and set the id value to it. And then at the server side in the action you can get it from FormCollection.
[HttpPost]
[ValidateInput(false)]
public ActionResult Insert(FormCollection formCollection)
{
//for example all hidden input controls start with "hidden_tag" id
//and end with your number of tag:
var allNeededKeys = formCollection.AllKeys.Where(x => x.StartsWith("hidden_tag"));
var listOfId = allNeededKeys.Select(formCollection.Get).ToList();
}
Good luck.
I'm pretty sure you can't. You can use fiddler to see if they're posted back to the server but I don't think they are.
You should use hidden fields to post the span's id to the server.
Is the view strongly typed?
