Try wrapping the "this" inside parentheses: $(this).someMethod

Hi, I have this Javascript in JSON notation and using the jQuery Ajax. var objectJSON = { myvalue: "hello", myFunction: function(param) { this.myvalue = param; $.ajax({ type: "POST", url: '/ajax/address.php', data: "param=" + param, success: this.pageLoadOk }); }, pageLoadOk: function(t){ $('#id-element').html(t); alert(this.myvalue); //*** this.myvalue is not accesible from here ***// alert(objectJSON.myvalue); //***It works **// }, ............ It seems that from myFunction I can access "this.myvalue" but not in pageLoadOk which the function It is executed when returning the Ajax response. I could do alert(objectJSON.myvalue) and it would work but I would prefer not to use instance names variables. My knowledge of Javascript is not very good and I am sure I am doing something wrong.... Thanks for your help CF
