Jquery and JS use external variables to obtain the parameter value returned by Ajax (super simple)_javascript skills

In the past, I only knew how to assign the value to the HTML control in the return data area, but later I discovered that it was just a matter of directly defining the variables.

Copy code The code is as follows:

var csj_data;

$.ajax
({
cache: false,
async: false,
type: 'post',
data: { aaa: "1" },
url: "../ handle/Ladder_Fee_Code.ashx?ajaxaction=Select_FangAn",
success: function (data) {


csj_data = data;
alert(data);
}
} );

alert(csj_data);
