javascript - Internet Explorer 8 不允许动态创建按钮

Question

当我尝试动态创建按钮时，Internet Explorer 显示错误。虽然它在 Firefox 中运行良好

var deleteButton = document.createElement('input');
 ratingSliderContainer.appendChild(deleteButton);
 deleteButton.setAttribute('type','button');
 deleteButton.setAttribute('value','delete');

它在第三行显示错误

Answer 1

type将输入添加到 DOM 后，您将无法修改它。尝试重新排序您的语句，如下所示：

var deleteButton = document.createElement('input');
deleteButton.setAttribute('type','button');
deleteButton.setAttribute('value','delete');
ratingSliderContainer.appendChild(deleteButton);
