Nice to meet you.Let me ask you a question.Currently, we have created and implemented textarea as follows for projects using angular.Unlike the basic textarea, I would like to submit the form by entering a value and pressing Enter.I've tried and tried, but I'm in trouble because I can't solveThe text sticks out a lot with input, so I really want to submit it with textarea.Thank you for your cooperation

mod.directive 'resizeTextarea', ->

restrict: 'A'
require: '?ngModel'
link:(scope, element, attrs, ngModel) ->
HEIGHT=25
el=angular.element(element[0])
el.css 'lineHeight', HEIGHT+'px'
el.css 'height', HEIGHT + 'px'
resize=(e)->
textHeight=e.target.scrollHeight
height=~(textHeight/HEIGHT)*HEIGHT
el.css 'height', height+'px'
return
el.on 'input', resize
scope.$watchattrs.ngModel, (value)->
if value == undefined
return
textHeight=el[0].scrollHeight
height=~(textHeight/HEIGHT)*HEIGHT
el.css 'height', height+'px'
return
ngModel.$parsers.unshift(viewValue)->
viewValue
return

I think you can check if Enter is pressed on the keypress and submit the form.
I have made a sample for writing in angular, so please refer to it.
var app=angular.module('app',[]);
app.controller("ctrl", function($scope){
$scope.text="init";
});
app.directive('enterSubmitForm', function(){
US>return{
controller:function($scope,$element){
This.submit=function(){
$element[0].submit();
}
}
}
});
app.directive('enterSubmit', function($rootScope){
US>return{
require: '^enterSubmitForm',
link:function($scope,$element,attrs,ctrl){
$element.on('keypress', function(e){
if(e.keyCode==13){
$rootScope.$apply(function(){
ctrl.submit();
});
}
});
}
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app"ng-controller="ctrl">
<form enter-submit-form>
<textarea-model="text"enter-submit></textarea>
</form>
</div>
