During webpage development, interaction with the front-end and back-end data is an unavoidable problem. Different business needs have different transmission methods, below are several transfer methods I have used in the development process. I will write them out and share them with you. Due to lack of experience, you are welcome to correct the errors.

1. pass through window. location. href or document. location. href,For example window. location. href = "http://www.ewcar.net? Name = sun & age = 21 "; in this example, the parameters are name and age, respectively sun and 21. Of course, you can also add the anchor #, you can specify a location on the page.

2. Use Ajax to transmit data in the following format:

$.ajax{    type: "post",    url: "test/index",    dataType: json,    data: $("#orderForm").serialize() ,    success: function(d){      alert(d.msg);    }    error:function(d){      alert(d.error);    }  }

Data indicates the data to be transmitted.

3. The post method of Ajax is used for transmission. The format is as follows:

  $.post({    "url",     $("#orderForm").serialize(),    function(d){      alert(d.msg);    }  });

In theory, this is also an Ajax method, but this method is relatively simple.

4. The action method in the form table can also transmit data, but the action method is relatively more comprehensive. You can jump to the connection or to text, images, videos, and other multimedia content, the link in the action and window. location carries parameters in the same way.

The above is the parameter passing method I have used. If you encounter a new method, update it again.
