在dijit.form.ValidationTextBox上設置約束

Question

我正在調用一個函數onblur ..該函數調用一個ajax和那個ajax獲取字符串..

現在我想如果字符串中的值可用..然后文本框變為紅色..

我的ajax代碼是

function ucheck(){
                dojo.xhrPost({
                    // The URL to request
                    url: "ucheck",
                    timeout :  3000 ,
                    content: {
                    username: dojo.byId("pref_id").value

                    },
                    // The method that handles the request's successful result
                    // Handle the response any way you'd like!
                    load: function(result) {
                        var fi=result;
                        document.getElementById('co').innerHTML=fi // this is print the value in lable


                    }
                });
            }
