var uid = users.id;
console.log(uid);//ID
console.log(returnCitySN["cip"]);ip if (uidsand undefined) {}
$(function () {
/ page rendering /
$.ajax ({
type:"POST",
dataType: "json", url: "URL",
data: {ip:returnCitySN ["cip"]}, this is the parameter to be passed.
now I want to make a judgment. If you can get the user"s id, you should wear data: {uid:uid};
if you can"t get the user"s id, send data: {ip:returnCitySN ["cip"]};
ask God for help?
var aData;<br>if(uid){
aData={uid:uid};
} else {
aData={ip:returnCitySN["cip"]};
}
$.ajax ({
)
data:aData
});
