This article mainly introduces the usage of html5 progress tag, as well as the usage of attributes of html5 progress tag. Next, let us read this article together

First we introduce the usage of the html5 progress tag:

The tag defines the progress of the operation (process).

You can use the tag to display the progress of time-consuming functions in javascript.

Indicates the progress of the task, the background is gray, and the completed part is filled with a pulsating green bar (but the styles are still different in different browsers).

Tip: Please use the tag to display the progress of the download.

Let us look at an example of using the html5 progress tag:

Mark "download progress":

对象的下载进度：
<progress value=&#39;70&#39; max=&#39;100&#39;></progress>

Copy after login

The effect is as shown:

The picture is obvious, so I won’t say more.

Now let’s talk about the attributes of the html5 progress tag:

1. You can set the percentage (0~1 decimal) through the value attribute

Usually we can also place the progress value inside the element, so that when the browser (www.php.cn) does not support it, the text can be displayed as a backup solution.

<progress value="0.25">25%</progress>

Copy after login

2. You can use the max attribute to set the maximum value. At this time, the range of value is 0~maximum value.

<progress value="25" max="100">25%</progress>

Copy after login

3. The value attribute indicates that the progress bar is completed. For progress, the value range is between 0 and max. If the max attribute is not set, the value attribute should range from 0 to 1.

If there is no value, then the completion progress is uncertain. At this time, it means that the task is in progress, but it is not known how long it will take to complete. At this time, progress can be used as loading in webkit browsers, indicating that the page is being loaded, or that Ajax is requesting background data.

If the value is not set, it will represent an uncertain progress bar (the progress will continue to slide in a loop)

<progress></progress>

Copy after login
