Hinzufügen eines HTML-Elements mit Javascript macht andere js wonky

Question

Ich habe den folgenden JavaScript-Code, der von der SimpleUpload-Demo in SWFUpload geändert wird. Es wird verwendet, um einen temporären Upload-Fortschrittsbalken zu generieren. Es funktioniert gut, es sei denn, ich füge den Code, der auskommentiert wurde, hinzu. Diese Zeile unterbricht im Grunde die Präsentation:

this.fileProgressElement.appendChild (document.createTextNode ("Upload Status"));

Demos: Versuchen Sie den Upload. Die Upload-Funktion funktioniert nicht.

Der Code ist:

function FileProgress(file, targetID) { 
    this.fileProgressID = file.id; 

    this.opacity = 100; 
    this.height = 0; 


    this.fileProgressWrapper = document.getElementById(this.fileProgressID); 
    if (!this.fileProgressWrapper) { 
     this.fileProgressWrapper = document.createElement("div"); 
     this.fileProgressWrapper.className = "progressWrapper"; 
     this.fileProgressWrapper.id = this.fileProgressID; 

     this.fileProgressElement = document.createElement("div"); 
     this.fileProgressElement.className = "progressContainer"; 
     //this.fileProgressElement.appendChild(document.createTextNode("Upload Status")); 

     var progressCancel = document.createElement("a"); 
     progressCancel.className = "progressCancel"; 
     progressCancel.href = "#"; 
     progressCancel.style.visibility = "hidden"; 
     progressCancel.appendChild(document.createTextNode(" ")); 

     var progressText = document.createElement("div"); 
     progressText.className = "progressName"; 
     progressText.appendChild(document.createTextNode(file.name)); 

     var progressBar = document.createElement("div"); 
     progressBar.className = "progressBarInProgress"; 

     var progressStatus = document.createElement("div"); 
     progressStatus.className = "progressBarStatus"; 
     progressStatus.innerHTML = " "; 

     var progressFull = document.createElement("div"); 
     progressFull.className = "progressBarFull"; 
     progressFull.innerHTML = " "; 

     this.fileProgressElement.appendChild(progressCancel); 
     this.fileProgressElement.appendChild(progressText); 
     this.fileProgressElement.appendChild(progressStatus); 
     this.fileProgressElement.appendChild(progressBar); 
     this.fileProgressElement.appendChild(progressFull); 
     this.fileProgressWrapper.appendChild(this.fileProgressElement); 

     document.getElementById(targetID).appendChild(this.fileProgressWrapper); 
    } else { 
     this.fileProgressElement = this.fileProgressWrapper.firstChild; 
     this.reset(); 
    } 

    this.height = this.fileProgressWrapper.offsetHeight; 
    this.setTimer(null); 


}
