推荐答案
您必须将按钮的ID更改为与函数名称不同 JSFiddle
You have to change the ID of the button to be different from the function name JSFiddle
var counter = 0;
function moreFields() {
counter++;
var newFields = document.getElementById('readroot').cloneNode(true);
newFields.id = '';
newFields.style.display = 'block';
var newField = newFields.childNodes;
for (var i = 0; i < newField.length; i++) {
var theName = newField[i].name
if (theName) newField[i].name = theName + counter;
}
var insertHere = document.getElementById('writeroot');
insertHere.parentNode.insertBefore(newFields, insertHere);
}
window.onload = moreFields();<div id="readroot" style="display: none">
