Implementation steps: 1. Listen to the scroll event of the page; 2. Determine the scroll to the bottom of the page; 3. Load the next page data; 4. Update the page scroll position.
To implement the function of sliding up on the web side to load the next page, you can use the following steps:
1. Listen to the scroll event of the page.
You can use the window.onscroll event in JavaScript to monitor the scrolling event of the page.
2. Scroll to the bottom of the page.
When the scroll event is triggered, you can use the following code to determine whether you have scrolled to the bottom of the page:
if (window.innerHeight + window.scrollY >= document.body.offsetHeight) {
// 滾動到頁面底部
}3. Load the next page of data.
When scrolling to the bottom of the page, the data for the next page can be loaded through an Ajax request and the data is inserted into the page.
4. Update the page scroll position.
After loading the next page of data, you can use the following code to restore the page scroll position to the position before loading:
window.scrollTo(0, window.scrollY - scrollHeight);
Where, scrollHeight is the scroll height of the page before loading.
The entire implementation steps can be represented by the following code example:
window.onscroll = function() {
if (window.innerHeight + window.scrollY >= document.body.offsetHeight) {
// 滾動到頁面底部
loadNextPage();
}
};
function loadNextPage() {
// 發(fā)送Ajax請求加載下一頁數據
// ...
// 恢復頁面滾動位置
window.scrollTo(0, window.scrollY - scrollHeight);
}Requires attention It is important to note that the above code is just a simple example, and the specific implementation may vary due to differences in project requirements and technology stacks.
