下面是javascript，调用ajax函数，$ajax在firefox中不起作用，但在chrome中可以工作。 ajax 在 Firefox 浏览器中未收到响应。

函数 ajaxAsyncRequest() {

            alert("ajaxAsyncRequest function"); 
            var tempValUrl = $(".urlVal").val(); 
            var url = tempValUrl + 'DepartmentUser/departmentUserTokenReceive'; 
            alert("url=="+url); 
 
                $.ajax({ 
                        url : url, 
                        method : 'GET', 
                        contentType : "application/json", 
                        dataType : "json", 
                        success : function(response) { 
                            alert(response); 
                            var obj = response; 
                            alert(obj); 
                            alert("keyType" + obj.keyType); 
 
                            if (obj.keyType == "sign") { 
                                document.getElementById("signName").value = obj.name; 
                                document.getElementById("certNumber").value = obj.serialNumber; 
                                document.getElementById("signCa").value = obj.issuer; 
                                document.getElementById("signExpiryDate").value = obj.tempDateTime; 
                                document.getElementById("signPublicKey").value = obj.publicKey; 
                            } 
 
                            if (obj.keyType == "cipher") { 
                                document.getElementById("cipherName").value = obj.name; 
                                document.getElementById("cipherCertNumber").value = obj.serialNumber; 
                                document.getElementById("cipherCa").value = obj.issuer; 
                                document.getElementById("cipherExpiryDate").value = obj.tempDateTime; 
                                document.getElementById("cipherPublicKey").value = obj.publicKey; 
                            } 
 
                        } 
 
                    }); 
        } 

请您参考如下方法:

您必须将事件定义为事件处理程序的参数:-

event.preventDefault();
