我想通过按钮单击事件通过具有相同标签id的标签的id获取元素.但是它只读取第一个元素的值.如果可以的话，请给我一种方法，让我可以读取标签的所有值.如果可以的话请帮助我.谢谢.

I want to get element by its id of a label with same tag id by a button click event. But it only read the first elements value. If you can please give me a method how I can read all the values of labels. If you can please help me. Thank You.

推荐答案

假设您的标签ID为="label1"

因此要在onclick上获得其价值，只需将代码放入onclick函数中，例如

suppose u have label with id ="label1"

so to get its value on onclick just put that code into onclick function like

function getvalue()
{
var value=

(" ).text(); }

("#label1").text(); }
