how homecoming response asynchronous call? 11 answers

i need alter var state on success, debugging js code, doesn't phone call success function @ all, though there success. state variable remains undefined. i'm not sure why doesn't change. looking @ network using firebug, response {"d": 1}, value state should have. help appreciated

var state; $.ajax({ url: "isoserve.asmx/getstatus", type: "get", contenttype: "application/json; charset=utf-8", datatype: "json", success: function (msg) { state = msg.d; }, error: function() { alert("error" ); } }); homecoming state;

you should return state within ajax call:

var state;

$.ajax({ url: "isoserve.asmx/getstatus", type: "get", contenttype: "application/json; charset=utf-8", datatype: "json", success: function (msg) { state = msg.d; homecoming state; }, error: function() { alert("error" ); } });

in case, return statement fires before ajax response come! says, asynchronous, need wait till gets response.

update:

you cannot have response ajax phone call directly, asynchronous request. instead, can invoke function in success callback, such function triggered , states set.

jquery ajax json
