Front end with ajax to send the answer to submit the json, back-end receives and judgment are consistent with the correct answer, and returns the results, the front-end receiving results, according to the results for different response

CodePudding user response:

Request callback, return to the success, according to the return value judgment operation again, this is the most basic things, such as
$. Ajax ({
Type: 'get',
. ,
Success: the function (res) {
If (res) code==200) {
Jump to the next topic
} else {
Alert (" wrong ")
}
}
})

CodePudding user response:

If it is a judgment, request the background directly transfer the user to enter the answers with the current topic is OK - & gt;
