HTML <input> alt 属性

HTML <input> 标籤

定义和用法

alt 属性为用户提供替代文本，如果他/她由于某种原因无法查看图像（因为连接速度慢、src 属性中的错误，或者如果用户使用屏幕阅读器）。

Note:alt 属性只能与 <input type="image"> together use.

Note:even alt Ang attribute ay hindi kinakailangan na attribute, ngunit kung ang uri ng input ay image, dapat pa ring itakda ang attribute. Kung hindi itakda ang attribute, maaaring magbigay ng sagabal sa mga text browser o non-visual browser.

Example

HTML form with an image button for submission:

<form action="/action_page.php">
  <label for="fname">Name:</label>
  <input type="text" id="fname" name="fname">
  <input type="image" src="submit.gif" alt="Submit" width="48" height="48">
</form>
