I have following span that I am using as a text input.
<span ng-model="sampleText" style="width:100px; padding:20px, 100px;" class="TextBox"></span>
Reason why I am using span instead of "input" or "textarea" is so that I have one box which can keep adding rows as I hit enter. This is more elegant way than showing a big box of textarea.
But problem I am facing is how do i bind the text that has been entered to the ng-model.
Maybe using ng-init?
Please let me know how to bind the text that has been entered to the "sampleText"
Thanks
The ngModel directive itself doesn't do much. It provides a controller that is used by other directives, like input (yes, input is a directive). That means you have to write your own one.
But you are lucky, because the documentation for the ngModelController has an example that's almost identical to yours.

In my file make-tweet.component.html, I have the next html tag:, which, I use it to be able to use a div as if it were an input because I add dynamic content with classes, that's why I don't use input.
<div (input)="handleText($event);" contenteditable="true" style="width:300px;"#textarea> </div>
With the (input) event, I can see the content of the label.
But what I need is to validate while the user is typing if he meets a requirement. If it doesn't, don't display anything in the "editablecontent" div, something like a "return false". I am using Angular 11.
I am going to design a textarea for writing some formula. Since typing entire formula may cause mistake in formula, I think its is better that users drag and drop variables from another panel. I believe that stackoverflow's tag option could be usefull for this purpose.
How it is possible to design a text area like this?
You cannot directly convert the text box into tag. But you can make it look like a text box by giving a container to have the tag inside and a text box.
<div id="container"><span id="tagContainer"></span>
<input type="text" id="inputText" placeholder="input here.." />
</div>
Using keypress event, you can grab the value of textbox and append it into tagContainer. You can see the implementation here: JSFiddle
You can't.
However you can put another text block with highlight content at same position with that textarea or input.

I have several polymer paper-input elements on a polymer app. When one of these elements is focused, I'd like the text input of the input be highlighted (like this) so that if a user just starts typing, the existing value of the input is overwritten.
Is there a way to highlight the text programmatically on focus?
I figured it out.
inputElement.$.input.select()
Would be nice if this were documented somewhere.
According to this documentation, inputElement will return a reference to the actual HTML input element implemented in <paper-input>. You need to access the native element as select() is not implemented directly in <paper-input>.
HTML:
<paper-input id="my-input" value="[[myInputText]]></paper-input>
JavaScript:
querySelector('#my-input').inputElement.select();
I use angularjs and xeditable in my application. I would like to change the behaviour of editable textarea and editable text to allow the validation when the user click outside.
It will be better with an example :
<span editable-textarea="item.label.text" e-rows="2" e-cols="80" buttons="no" onshow="onShow()" onhide="onClose()">{{item.label.text}}</span>
With this code, we can't see the buttons to validate and to cancel our choice. Moroever the enter key doesn't validate, so it's impossible for the user to validate his choice.
What I want to do is changing the behaviour of the enter key to validate the new text. And I want to add the possibility for the user to change text and when he click outsite the textarea, the new text will be save.
The problem is I have no idea of how to do that even after reading all the documentation of xeditable and I didn't find the solution on any forum.
Do you have an idea of how can I do that ?
Thank you in advance
You can add the blur attribute with submit value and couple it with onbeforesave attribute:
<span editable-textarea="item.label.text" e-rows="2" e-cols="80" buttons="no" onshow="onShow()" onhide="onClose()" blur="submit" onbeforesave="validate($data)">{{item.label.text}}</span>

I need to display some text but the text is going to change a lot and I need for it to be editable. I know I can use from input but is there any other way?
MDN has a nice example and MSDN - here for contenteditable
<div id="toEdit" contenteditable="true" onkeyup="doSomething(this.id);"></div>
doSomething function can manipulate the data (store/send whatever).
You can use ajax query and change the value of the text area.. using that.. hope this help
you can put a little button (or use even the text itself as a handler) so that when a user clicks, you add the input to change the text using ajax.
