How to get the project name in jquery

In front-end development, we often need to obtain the project name for splicing to generate a complete URL path. When developing with jQuery, we can get the project name in the following way.

1. Use the location object to obtain

In JavaScript, the URL information of the current page can be obtained through the location object, including protocol, host, path, etc. We can obtain the path information of the current page through the location.pathname attribute, and then intercept the project name from it. The sample code is as follows:

var pathName = location.pathname; // 获取当前页面路径
var projectName = pathName.substring(0, pathName.lastIndexOf('/')+1); // 截取项目名
console.log(projectName); // 输出项目名

Through the above method, we can easily obtain the project name and use it in other URL splicing.

2. Use regular expressions to obtain

In addition to using the location object to obtain the project name, we can also obtain it through regular expressions. The following regular expression can match the project name:

var projectName = /^/w+//g.exec(location.pathname)[0];
console.log(projectName); // 输出项目名

The advantage of obtaining the project name through regular expressions is that it can match the project name more accurately and avoid obtaining the wrong project name due to special circumstances.

3. Encapsulated function acquisition

In addition to the above two methods, we can also encapsulate the method of obtaining the project name into a function to facilitate reuse in the project. The sample code is as follows:

function getProjectName() {
    var pathName = location.pathname;
    var projectName = pathName.substring(0, pathName.lastIndexOf('/')+1);
    return projectName;
}
console.log(getProjectName()); // 输出项目名

By encapsulating the function, we can call the function at any time in the project to obtain the project name, without having to write the same code every time.

Summary

The above are several ways to get the project name in jQuery. Different methods can be flexibly selected according to specific project needs. No matter which method is used, the purpose of obtaining the project name is to generate a complete URL path, thereby making page jumps more convenient.
