How to limit the number of “FileUploadBox()” button?
I was developing up my new web form and I'm putting some files upload boxes.
I already got it and make it work, but I'm struggling with how limit the upload files buttons.
I want to limit to a maximum of five buttons.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<script>
function addFileUploadBox() {
if (!document.getElementById || !document.createElement)
return false;
var uploadArea = document.getElementById("upload-area");
if (!uploadArea)
return;
var newLine = document.createElement("br");
uploadArea.appendChild(newLine);
var newUploadBox = document.createElement("input");
newUploadBox.type = "file";
newUploadBox.size = "30";
if (!addFileUploadBox.lastAssignedId)
addFileUploadBox.lastAssignedId = 100;
newUploadBox.setAttribute("id", "FileField" +
addFileUploadBox.lastAssignedId);
newUploadBox.setAttribute("name", "FileField" +
addFileUploadBox.lastAssignedId);
uploadArea.appendChild(newUploadBox);
addFileUploadBox.lastAssignedId++;
}
</script>
<p id="upload-area">
<input type="file" name="file" id="file" size="30">
</p>
<input type="button" value="Attach more files" id="btAdd" class="button1"
onclick="addFileUploadBox()">
</body>
</html>
Please guys, give me a light of how may I could solve it.

Inside your addFileUploadBox function, you can check to see if there are already 5 boxes on the page, and prevent it from creating more.
if(document.querySelectorAll('#upload-area input[type="file"]').length >= 5) return false;
