Ajax request parameters, get and post

When Ajax is used to send request parameters to the server, different information can be requested from the server. The same as submitting a common table, the Ajax-based request can also be divided into get and post.

Use the get Method

You can use the get method to directly obtain the server bed parameters by adding the constructed request string to the end of the URL. The following sample code is used:

var name = document.getElementById('username').value;var gender = document.getElementById('gender').value;url = 'process.php';query = '?name=' + name + '&gender=' + gender;url+=query;

The final string is like process. php? Name = xxx & Gender = yyy.

POST method

When the POST method is used for submission, the URL does not need to be changed, and the request parameter must be used as the send parameter.

VaR name = document. getelementbyid ('username '). value; var gender = document. getelementbyid ('gender '). value; query = 'name = '+ name +' & Gender = '+ gender ;//...... Construct the code of the XMLHttpRequest request ...... Request. Send (query );

There is no difference between query strings except for one greeting.
