Is there a way to have AngularJS evaluate an expression within model data?
HTML:
<p>
{{Txt}}
</p>
Model:
{
Txt: "Can AngularJS process an expression in the model data? {{Rest}}"
}
{
Rest: "including this additional text."
}
The desired output should be:
Can AngularJS process an expression in the model data? including this additional text.You have the option to utilize the $interpolate service in order to perform string interpolation...
function modifyText ($scope, $interpolate) {
$scope.Text = "Here is a sample text {{Remaining}}";
$scope.Remaining = "and this part comes next.";
$scope.performInterpolation = function (value) {
return $interpolate(value)($scope);
};
}
<div ng-app ng-controller="modifyText">
<input ng-model="Text" size="60" />
<p>{{ Text }}</p>
<p>{{ performInterpolation(Text) }}</p>
</div>
You have the ability to run JavaScript code within the curly brackets:
<p>{{Text + ' ' + MoreText}}</p>
Alternatively, you can define a function that will output the desired text:
$scope.generateText = function() {
return $scope.Text + ' ' + $scope.MoreText;
}
<p>{{generateText()}}</p>
If you're working with javascript in your model, a straightforward approach would be:
let additionalInfo = 'and here is the extra information';
$scope.text = 'This is some content ' + additionalInfo;
Then, in your view, include <p>{{text}}</p>
Another option is to combine the variables like so:
<p>{{text}} {{additionalInfo}}</p>Currently, I am attempting to capture an HTMLCanvasElement and showcase the result on a different webpage without the need for uploading the image to a server. Initially, my plan was to store the image in local storage as a base64 data URI, but upon inspec ...
