css setting is not clickable

In web development, we often encounter a situation where we need to block the click event of a certain element so that it has no reaction when the user clicks it. At this time, we can use CSS to set the element to be non-clickable to achieve this function.

1. CSS pointer-events attribute

The pointer-events attribute of CSS can be used to control whether an element is clickable. The values ​​of this attribute are as follows:

• auto: default value, the element can be clicked;
• none: the element cannot be clicked, but the child elements can be clicked;
• visiblePainted: The element cannot be clicked, but the cursor can be seen;
• visibleFill: The element cannot be clicked, but the cursor can be seen and the element will be filled;
• visibleStroke: The element cannot be clicked Click, but the cursor is visible and the element's outline appears.

2. How to use the pointer-events attribute

We can add a class to the element that needs to block click events, and then style the class in the CSS file so that Its pointer-events attribute can be none.

For example, if we have a button and want it to be unclickable under certain circumstances:

HTML code:

<button class="disable-btn">点击我</button>

CSS code:

.disable-btn {
    pointer-events: none;
}

When the disable-btn class is added to the button, an effect will appear, that is, when we try to click the button, it will not react in any way.

3. Issues that need attention

It should be noted that when the pointer-events attribute is applied to an element, it will not only affect the mouse click event, but also affect all the events on the element. Mouse events. Therefore, if we need to use mouse events in certain scenarios and set pointer-events, these mouse events will also be blocked.

In addition, it should be noted that the pointer-events attribute is not supported by all browsers. For example, in IE browser, the pointer-events attribute can only be applied to SVG elements, but ordinary elements are not supported.

4. Summary

The pointer-events attribute of CSS is a relatively simple method to make the element non-clickable. You can block the element by setting the pointer-events attribute of the element to none. click event. However, it should be noted that this method will affect all mouse events on the element, and not all browsers support the pointer-events attribute. In actual development, we need to choose whether to use this method based on the actual situation.
