Hallo Siechfred.
function test_me() {
var url = document.Formular.bild.value;
var img = new Image();
img.onload = function() { alert(this.width+" x "+this.height); };
img.onerror = function() { alert(this.src + " ist keine Grafikdatei!"); };
img.src = url;
}
Bist du sicher, dass es nicht so aussehen müsste?
~~~javascript
function test_me() {
var url = document.Formular.bild.value;
var img = new Image();
img.src = url;
img.onload = function() { alert(this.width+" x "+this.height); };
img.onerror = function() { alert(this.src + " ist keine Grafikdatei!"); };
}
Auf wessen src, width und height sollte sonst zugegriffen werden?
Einen schönen Montag noch.
Gruß, Ashura
