I have problem with blade front-end. After I click button-search, component-search auto change component view show text wire:id<####>, instead of component-search view.
Example image:
enter image description here
It should have been <div wire:id="xxx"> that's how Livewire marks it's components. Make sure you don't have javascript doing some DOM manipulation. Check your template for more information
I am new to React TypeScript. I have a problem with the passing state. When I tried to pass the state to a child component and conosle.log(state), I can see the correct object. But, when I tried to do console.log(state.name), I have an error. How can I solve this problem?
App.tsx
export interface Information {
name: string;
age: string;
}
const App: FC = () => {
const [state, setState] = useState<Information | null>({
name: "young",
age: "10",
});
return (
<div className="App">
<div className="header">
<div className="inputContainer">
<input type="text" placeholder="Task.." name="task" />
<input type="number" placeholder="Deadline" name="deadline" />
</div>
<button>Add Task</button>
<div>
<MyForm state={state} />
</div>
</div>
</div>
);
};
Child component
type Props = {
state: ReactNode;
};
const MyForm: FC<Props> = ({ state }: Props) => {
console.log(state.name); // Error
return <div>Hello, {state}</div>;
};
export default MyForm;
Thank you!
The error because you're trying to read the state object inside JSX
return <div>Hello, {state}</div>
Read it like you would with objects instead:
return <div>Hello, {state.name}</div>
Also in your MyForm Component Props, use your Information interface as a type definition instead of ReactNode
export interface Information {
name: string
age: string
}
type Props = {
state: Information
}
I'd like to know what is the best way to avoid using multiple *ngIf in template. For example, in a component's template, depends on the route, i have to generate multiple different elements like that:
<div *ngIf="route == 'page1'">Title for page 1</div>
<div *ngIf="route == 'page2'">Title for page 2</div>
<i *ngIf="route == 'page1'" class="fa fa-message"></i>
<i *ngIf="route == 'page2'" class="fa fa-bell-o"></i>
<div *ngIf="route == 'page1'">
<button>...</button>
</div>
<div *ngIf="route == 'page2'">
<div class="menu"></div>
</div>
It'll become messy soon, so i came up with a solution, in this component's ts file, i defined an array:
arr_1 = [
{ type: "text", content: "Title for page 1" },
{ type: "icon", class: "fa fa-message" },
{ type: "button", content: "..." }
]
arr_2 = [
{ type: "text", content: "Title for page 2" },
{ type: "icon", class: "fa fa-bell-o" },
{ type: "menu", menu_children: [...], class: "menu" }
]
In its template:
<div *ngIf="route == 'page1'">
<generator *ngFor="let ele of arr_1"
[type]="ele.type"
[class]="ele.class"
[content]="ele.content"
[menu_children]="ele.menu_children"
>
</generator>
</div>
<div *ngIf="route == 'page2'">
<generator *ngFor="let ele of arr_2"
[type]="ele.type"
[class]="ele.class"
[content]="ele.content"
[menu_children]="ele.menu_children"
>
</generator>
</div>
And i created a GeneratorComponent that receives the type and generate the corresponding element:
#Component({
selector: 'generator',
...
})
export class GeneratorComponent {
#Input() type: string;
#Input() content: string;
#Input() class: string;
#Input() menu_children: string;
}
GeneratorComponent's template:
<div *ngIf="type == 'text'">{{ content }}</div>
<i *ngIf="type == 'text'">{{ content }}</i>
...
The problem here is the class GeneratorComponent will have multiple properties and they are not used for one reason (for example: content and menu_children have no relation).
Do you have any idea to fix my solution ? Other solutions will be appreciated.
Thanks !
You could use the helper element <ng-container>. It allows to apply structural directives *ngIf, *ngFor, ..., without actually adding an element to the DOM
<ng-container *ngIf="route == 'page1'">
<div>Title for page 1</div>
<i class="fa fa-message"></i>
<div>
<button>...</button>
</div>
</ng-container>
<ng-container *ngIf="route == 'page2'">
<div>Title for page 2</div>
<i class="fa fa-bell-o"></i>
<div>
<div class="menu"></div>
</div>
</ng-container>
<div [ngSwitch]="route">
<generator ngSwitchWhen="page1" *ngFor="let ele of arr_1"
[type]="ele.type"
[class]="ele.class"
[content]="ele.content"
[menu_children]="ele.menu_children">
</generator>
<generator ngSwitchWhen="page2" *ngFor="let ele of arr_2"
[type]="ele.type"
[class]="ele.class"
[content]="ele.content"
[menu_children]="ele.menu_children">
</generator>
</div>
If it depends on route, why not have two components and display the right one based on the current route via router-outlet
i.e. have a Page1Component and Page2Component and configure routes for them in the appropriate routing.ts file
[
..
{
path: 'page1',
component: Page1Component,
},
{
path: 'page2',
component: Page2Component,
},
]
Then each Page component can define exactly what should be displayed.
Im new to Ember and I am trying to create a record by submitting a form. This is the code I've written so far:
App.CharactersNewRoute = Ember.Route.extend({
model: function() {
return this.store.createRecord('character', {name: '', race: ''});
}
});
<form {{action "createCharacter" on="submit"}}>
<div class="form-group">
<label>Name</label>
{{input value=characterName class="form-control"}}
</div>
<div class="form-group">
<label>Race</label>
{{input id=characterRace class="form-control"}}
</div>
{{#link-to 'characters'}}<button class="btn btn-default">Back</button>{{/link-to}}
<button class="btn btn-default" type="submit">Create</button>
</form>
App.CharactersNewController = Ember.ObjectController.extend({
actions: {
createCharacter: function() {
var name = this.get('characterName'),
race = this.get('characterRace');
if (!name || !race) { return false }
// create new character
var character = this.store.createRecord('character', {
name: name,
race: race
});
this.set('characterName', '');
this.set('characterRace', '');
character.save();
}
}
})
Right now, the code stops at the var character = this.store.createRecord line in the controller, but no errors are raised in the console
Thanks

Crashes on the replace method, because the method replace is undefined

So first of all you need to define only need to define the controller. You don't have to create an instance. Ember will do it for you when application initialize.
If you define a property that is observing another in other words its value depends on another, you need this to specify as parameter to property helper.
Thoughts.ComposerController = Ember.Controller.extend({
mode: 2,
visible: false,
messageContent: "",
buttonText: function () {
switch (this.get("mode")) {
case 1: return "Post";
case 2: return "Reply";
}
}.property('mode'),
display: function () {
return 'display:' + this.get('visible') ? 'block' : 'none';
}.property('visible'),
Toggle: function () {
this.toggleProperty('visible');
this.set('mode', this.get('mode') == 2 ? 1 : 2);
}
});
Template itself seems valid.
You can get this working by creating a composer route like this:
this.route('composer');
or by rendering it in another template like this:
{{render 'composer'}}
That should be answer to your question. BUT
Wouldn't be better to use {{if}} helper for showing some content inside of template based on a condition?
i finally found some time to work on this again.
all i did was replace the ember and handlebars js files, and the code is working fine now thanks
