CodePudding user response:

Brother: not solid basic skills,

Upstairs there are brothers, let use dataType: 'HTML', not wrong, but I don't recommend to do so is not professional,

Suggested use: dataType: 'json'

You can do it

The PHP side:

//normal return parameter
$code=0;
//error return parameter
$code=1;

//return data sets, can be an array, a string, numeric...
$result=1;

$data [
=https://bbs.csdn.net/topics/'code'=& gt; $code,//according to the business here, oneself hold
'data'=$result
];
Echo json_encode ($data);

Ajax front end success that place:
Success: the function (data) {
Var code=data. The code;
Var data=https://bbs.csdn.net/topics/data.data;
If (code==0) {
//return right

} else {
//warning instructional quality return

}

}
