jquery remove overflowx

In web design and development, CSS properties are a common markup language we are familiar with. Among them, the overflow attribute is often used to specify how the overflow content of an element is handled. By default, if the element content exceeds its specified size range, it will be processed according to the value of the overflow attribute.

When the value of the overflow attribute is hidden, the overflow content will be cropped and hidden. When its value is scroll, the page will automatically add scroll bars to facilitate users to view all content. When its value is auto, it will dynamically determine whether a scroll bar needs to be added based on the size of the browser window.

However, these methods become more cumbersome when we need to process the overflow attribute of all elements in the entire page at once. At this point, we can use jQuery to achieve this goal.

First, before using jQuery to modify the overflow attribute, we need to introduce the jQuery library. Depending on the situation, it can be introduced in the following ways:

<script src='https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js'></script>

Next, we can use jquery’s $ symbol to select all elements in the page, and use the css() function to directly modify its overflow attribute:

// 移除所有元素的overflow-x属性
$(document).find('*').css('overflow-x','inherit');

In this example, we use the find() function and the '*' wildcard to select all elements in the entire page. The effect of setting the overflow-x attribute to inherit is that it will inherit the overflow-x attribute of the parent element, thereby removing the original overflow-x attribute.

If we only need to remove the scroll bar rather than hide the overflow content, we can also use the css() function to modify the properties. The specific code is as follows:

// 移除所有元素的overflow属性
$(document).find('*').css('overflow', 'unset');

In this example, we set the overflow attribute to unset. The value of this attribute is somewhat similar to inherit, which causes the element to inherit the attribute value from its parent element. But unlike inherit, if the element itself has defined the overflow attribute, then the attribute value will be replaced by unset instead of being inherited.

In daily work, using jQuery to remove the overflow attribute from the page is a very useful technique. It should be noted that when using it, you must pay attention to the range of selected elements to avoid accidentally deleting or interfering with the normal display of other components.

In short, jQuery shows high efficiency and excellent performance when dealing with web design. Knowing some jQuery usage skills will be very helpful for web front-end developers.
