In web development, jQuery is often used to interact with front-end pages. In some special cases, it is necessary to modify some data in the page through JavaScript, and then let the page reload to display the modified content. Here are some simple methods you can use to achieve this functionality.
This is one of the simplest methods: when you need to reload the page, just call window.location. Just reload() method. However, using this method will reload the entire page, including all external scripts and resources, which will cause great performance consumption.
You can use the jQuery.ajax() method to get certain content in the page and then reload the content. For example:
$(document).ready(function() {
$('#submit-form').on('click', function(event) {
// 防止表单默认提交 event.preventDefault(); // 获取表单中的数据 var formData = $('#form').serialize(); // 发送 jQuery Ajax 请求 $.ajax({ url: '/update', type: 'POST', data: formData, success: function(data) { // 重新加载内容 $('#result').html(data); } });
});
});
When the user clicks the "submit-form" element, it will prevent the form from being submitted by default, and use the jQuery Ajax method to get the form data and send it to the server"/ update" address.
Once the data is successfully updated, the code in the jQuery success function will reload the data element on the page.
Another method is to use JavaScript localStorage. You can save the data you want to reload in localStorage and when the page loads check if localStorage contains the data. If so, reload the data.
The following are the implementation steps:
// Save data to localStorage
localStorage.setItem('myData', JSON.stringify(someData));
/ / Check if there is data and reload
window.onload = function() {
var myData = localStorage.getItem('myData');
if (myData) {
// 重新加载数据 $('#data-container').html(JSON.parse(myData));
}
}
When the page loads, we check localStorage to see if there is any stored data. If so, reload the data.
Summary
It is easy to reload and display the modified data in the page using one of the above methods. You can choose the method that suits your application requirements. If you just need to reload the entire page, use window.location.reload. If you need to load part of the page then use jQuery.ajax() or localStorage.
