jQuery plug-in jQuery-JSONP development ajax call usage precautions_jquery

JSONP call sample code:

Copy code The code is as follows:

var originImgSrc = 'cnbogs-logo.gif';
$.jsonp({
url: '',
data: { imgSrc: originImgSrc },
callbackParameter: "callback",
success: function (newImgSrc, textStatus, xOptions) {
console.log(xOptions.data.imgSrc);
},
error: function (xOptions, textStatus) {
}
});

The first thing to pay attention to is the callbackParameter. If there is no special callback function, be sure to write "callback";

The second thing to pay attention to is in the success callback function, directly through The variable name originImgSrc is undefined and needs to be obtained through xOptions.data.imgSrc.
