当使用javascript单击任意按钮时如何设置标签焦点

Question

I have one asp:Textbox and one asp:label control in my aspx page. I want to set focus for label when clicking the button using javascript. Can anyone tell me how to do this?

Many thanks...

Answer 1

You need to access the element via an id or a class an call focus() :

document.getElementById('myTextBox').focus();    

As Pointy pointed out: When you mean by clicking on a label to select the textbox, you just need to set the for attribute on the label to the ID of the textbox.

<label for="myTextBox">Label Text</label>

Answer 2

The for attribute does it for you out of the box

<label for="{the id you want}"> </label>

MDN

Because it's asp.net application you need to use the ClientID :

<label for='<%= myTextBox.ClientID %>'> </label>

Answer 3

use `.focus()` it will do the focus part
