我有点新角.我已经建立了"员工搜索"服务模块.这是代码......
// Service for employee search
app.service('employeeSearchService', function($http, resourceServerAddress){
this.empList = [];
// Method for clearing search employee list
this.clearEmpList = function(){
this.empList = [];
}
// Method for fetching employee search list
this.fetchEmpList = function(){
return this.empList;
}
// Method for making employee search
this.searchEmpList = function(empName){
var postData = {
empName:empName,
};
$http({
method: 'POST',
url: resourceServerAddress,
data : postData
}).then(function successCallback(response) {
console.log('Response Data : '+response);
if(response['data']['status'] === 'success'){
console.log('Response received successfully with status=success');
if(response['data']['data'].length)
{

现在，我使用以下代码来创建客户端 ID 和客户端机密令牌。
$token = bin2hex(random_bytes($length));
但是，有点混乱。是否，这是做这件事的正确方法吗？我还搜索了任何图书馆来做到这一点。但是，一个都没有。

我想知道是否有任何方式我们可以知道浏览器的事件..像:单击BACK按钮,FORWARD按钮,REFRESH按钮通过JavaScript.
可能重复:
禁用浏览器的后退按钮
有没有办法通过javascript禁用浏览器(特别是IE)BACK按钮,FORWARD按钮,REFRESH按钮.因此,当任何用户点击任何按钮时,什么都不会发生.
