To get the active element you can use 要获得活动元素,您可以使用
var input = document.activeElement;
if (input.tagName == "INPUT" || input.tagName == "TEXTAREA")
{
input.value = "today's date";
}
You can use 您可以使用
document.activeElement
To get the current active element. 获取当前活动元素。
Then you can use it to input the data, like so 然后您可以使用它来输入数据,就像这样
if (document.activeElement.nodeName === 'INPUT') {
document.activeElement.value = new Date().getTime();
}
But your better off adding a focus
event to the element 但是最好将
focus
事件添加到元素
