Submit-area unui FORM intr-un IFRAME generat dinamic (DOM)
In cazul in care un FORM, contine elemente de tip file, acest FORM nu poate fi submit-at prin AJAX ci intr-un IFRAME, generat dinamic, ascuns. Toate bune si frumoase in FireFox si Opera dar in Internet Explorer, rezultatul submit-arii formului era deschis intr-o noua fereastra!Pentru a face ca sin in IE, submit-area sa se produca in acest IFRAME generat dinamic, solutia e data in urmatoarea bucata de cod:
| Cod: |
| var iFrameID = 'ID1'; var myIFrame = document.createElement('iframe'); myIFrame.setAttribute('src', 'about:blank'); myIFrame.setAttribute('id', iFrameID); myIFrame.setAttribute('NAME', iFrameID); myIFrame.style.display = 'none'; document.body.appendChild(myIFrame); if((onReadyFunction) && (typeof(onReadyFunction) == 'function')) captureEvent('load', function(){ var iFrame = document.getElementById(iFrameID); var doc = (iFrame.contentDocument)?(iFrame.contentDocument):((iFrame.contentWindow)?(iFrame.contentWindow.document):(self.frames[iFrameID].document)); if (doc.location.href == 'about:blank') { return; } else { onReadyFunction(doc.body.innerHTML); } }, myIFrame); if(self.frames[iFrameID].name != iFrameID) { /* *** IMPORTANT: This is a BUG FIX for Internet Explorer *** */ self.frames[iFrameID].name = iFrameID; } |
Dupa ce IFRAME-ul este creeat, trebuie verificat daca self.frames[iFrameID].name este egal cu iFrameID
