Angular - Switching Displayed Information

I am currently working with Angular 4 and I am attempting to switch between contenteditable="true" and contenteditable="false"

Here is what I have so far:

<h1 (dblclick)="edit($event)" contentEditable="true">Double-click Here to edit</h1>

Alternatively, I could use a checkbox for toggling the edit mode if that would be simpler?

<input type="checkbox" name="" value="" (onchange)="edit($event)">Toggle Edit mode

and in the corresponding TypeScript file:

edit(event) {
    // additional code required here
}
javascriptangulartypescript

Answer №1

Implement a one-way binding linking the contentEditable feature to a field within your Component, then incorporate an event binding for the click action on the header.

Within your component, establish a boolean variable:

private isContentEditable = false;

Next, in your HTML code, toggle the value of this boolean using a click event, and connect the contentEditable attribute to this boolean as well:

<h1 (dblclick)="isContentEditable = !isContentEditable" [contentEditable]="isContentEditable">

If preferred, you can also encapsulate the code within the (dblclick) binding into a method within your component, such as toggleContentEditability(), allowing for additional functionalities.

Answer №2

Here are the necessary steps.

HTML

<h4 (dblclick)="contentEditable=true; toto.focus()"
    *ngIf="!contentEditable">
  {{myText}}
</h4>
<input #toto
       autofocus
       *ngIf="contentEditable"
       [value]="myText"
       (keyup.enter)="contentEditable=false; save(toto.value)"
       (blur)="contentEditable=false; save(toto.value)"
       type="text">

TypeScript

myText = "Double-click Here to edit";

By applying some css, you can switch one for the other seamlessly.
