How to store different values with the same key in memcache?

jQuery: How can I store the JSON response values in variable?

• My script as follows: var initilization; function onshow(fileid) { $.ajax({ "url": 'GetTags.ashx?fileid=' + fileid, "dataType": "text", "success": function(result) { initilization = result; alert('success result=' + initilization); } }); alert('initilization=' + initilization); } But the execution results are: success result=Cloud Computing initilization=undefined It looks that the response values can't be stored in variables. How can I store the JSON response values in variable via JS? Thank you.

• Answer:

  It is stored,  but the alert statement following he $.ajax call is executed before the assignment takes place. It happens because the success callback is called when a result comes from an AJAX call (i.e. asynchronously). I.e. a result of AJAX request should be processed inside a calback. However, you can store them in a global variable and access data later (but make sure, it happens after an assignment had been performed).
