我正在使用HTML5表单验证来验证来自印度的电话号码.
来自印度的电话号码长10位,以7,8或9开头.
例如:
这些电话号码有效,但是
无效.
建议一种可以检测有效印度电话号码的模式.
到目前为止,我的模式是[0-9]{10},但它不检查第一个数字是7,8或9.
我正在使用Cookies模块来设置cookie.这是我的代码:
var options = {
maxAge: ALMOST_ONE_HOUR_MS,
domain: '.test.com',
expires: new Date(Date.now() + ALMOST_ONE_HOUR_MS)
};
var value = userInfo.token;
cookies.set("testtoken", value, options);
但在文档中我还没有找到如何销毁这个cookie.
任何建议将不胜感激.
这是我的文件结构
-main.js
-SomeDir
-fileA.js
-fileB.js
如果我想main.js在someDir不指定文件名的情况下 加载(内部)每个文件,我该怎么办？
类似的东西:require(./someDir/*.js)？
我有角度应用程序,我想在查询字符串中传递加号+,如:
http://localhost:3000/page?name=xyz+manwal
当我点击此URL时,它将转换为:
http://localhost:3000/page?name=xyz%20manwal
凡%20指的空间.我该如何阻止这种转换？
我正在使用curl请求另一个站点获取数据.我的curl_reset()funciton 代码在localhost上运行良好,但是当我将代码更新到服务器时.它给出错误
致命错误:在2054行的/data/html/reviewkiller1.0/controller/searchController.php中调用未定义的函数curl_reset()
注意:我已检查curl扩展名是否已启用.
为什么会这样？

如果我重新启动系统,Hbase将开始工作.但我想要适当的解决方案. …
