我正在尝试向使用Google Apps脚本网络应用创建的自定义表单中动态添加额外的Materialize“选择”。尽管最初的显示为OK,但是在添加其他内容(通过“添加行”按钮)时,新选择具有两组选项。
谁能看到我在做什么错吗?
Code.gs
function doGet(e){
return HtmlService.createTemplateFromFile("Page").evaluate();
}
function include(filename){
return HtmlService.createHtmlOutputFromFile(filename).getContent();
}

Page.js.html
<script>
var selectorCount = 0
function onLoad() {
addRow()
document.getElementById("add-row-btn").addEventListener("click", addRow);
}
function addRow() {
var documentFragment = document.createDocumentFragment();
var temporaryNode = document.getElementById('row-template').cloneNode(true); //true for deep clone
documentFragment.appendChild(temporaryNode)
document.getElementById('invoice-form').appendChild(documentFragment)
var elements = document.querySelectorAll('select');
var element = elements[selectorCount++]
selector = M.FormSelect.init(element);
temporaryNode.style.display = "block"
delete documentFragment
}
</script>
关于Although the initial one displays OK, on adding extra (via the "Add Row" button) the new select has two sets of options.
的问题。我认为原因可能是id
附加在invoice-form
中使用了相同的appendChild(documentFragment)
。那么下面的修改如何?
function addRow() {
var documentFragment = document.createDocumentFragment();
var temporaryNode = document.getElementById('row-template').cloneNode(true); //true for deep clone
documentFragment.appendChild(temporaryNode)
function addRow() {
var documentFragment = document.createDocumentFragment();
var temporaryNode = document.getElementById('row-template').cloneNode(true); //true for deep clone
temporaryNode.id = temporaryNode.id + selectorCount; // Added
documentFragment.appendChild(temporaryNode)
