js函数传入参数为字符串的解决方法

  当js函数拼接传入参数为字符串时：报错Onclick Syntaxerror: identifier starts immediately after numeric literal

  错误示例：

       var device_mac = '11sesafsd23asd';

       return "<button οnclick='test(" + device_mac + ")'";

   正确做法:

   var device_mac = '11sesafsd23asd';

   return "<button οnclick='test(\"" + device_mac + "\")'";
