When i run my application it gives me several errors:
the first one is:
SyntaxError: class is a reserved identifier in the class thumbnail
code:
const MAXHEIGHT = 170;
const MAXWIDTH = 320;
import {Subcategory} from './subcategory'
//import {Category} from './category'
import {bootstrap} from 'angular2/platform/browser'
class Thumbnail {
width: number;
height: number;
constructor(element: HTMLImageElement) {
this.height = element.height;
this.width = element.width;
}
resize(oImage: HTMLImageElement) {
var maxWidth = 100; // Max width for the image
var maxHeight = 100; // Max height for the image
var ratio = 0; // Used for aspect ratio
var width = oImage.width; // Current image width
var height = oImage.height; // Current image height
// Check if the current width is larger than the max
if (oImage.width > MAXWIDTH) {
ratio = MAXWIDTH / width; // get ratio for scaling image
oImage.width=MAXWIDTH; // Set new width
oImage.height=height * ratio; // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
width = width * ratio; // Reset width to match scaled image
}
// Check if current height is larger than max
if (height > MAXHEIGHT) {
ratio = MAXHEIGHT / height; // get ratio for scaling image
oImage.height= MAXHEIGHT; // Set new height
oImage.width= width * ratio; // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
height = height * ratio; // Reset height to match scaled image
}
// Check if current height is smaller than max
if (height < MAXHEIGHT) {
ratio = MAXHEIGHT / height; // get ratio for scaling image
oImage.height = MAXHEIGHT; // Set new height
oImage.width = width * ratio; // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
height = height * ratio; // Reset height to match scaled image
}
// Check if the current width is smaller than the max
if (oImage.width < MAXWIDTH) {
ratio = MAXWIDTH / width; // get ratio for scaling image
oImage.width = MAXWIDTH; // Set new width
oImage.height = height * ratio; // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
width = width * ratio; // Reset width to match scaled image
}
document.body.appendChild(oImage);
console.log(oImage.height);
console.log(oImage.width);
}
};
window.onload = () => {
var oImage = new Image();
var oImage2 = new Image();
// var category = new Category(1, "string");
var subcategory = new Subcategory("teste",1,2);
oImage.src = 'AngularJS.png';
oImage.setAttribute('class','img-responsive');
oImage2.src = 'ts.jpg';
var thumbnail = new Thumbnail(oImage);
var thumbnail2 = new Thumbnail(oImage2);
thumbnail.resize(oImage);
thumbnail2.resize(oImage2);
console.log(oImage.height);
console.log(oImage.width);
};
The second error is:
GET http://localhost:51580/app
301 Moved Permanently
The configuration of angular is:
<script>
System.config({
packages: {
TypeScriptHTMLApp1: {
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('app')
.then(null, console.error.bind(console));
</script>
I already tried to create a folder named app and moved the file for that folder but the error persists. I need help with this, I lost several hours and can't resolve anything. I attach one image with the file structure and another one with the firebug errors. Thanks in advance.
