Javascript implementation is similar to getClass () in java to get the object class name _ javascript tips-js tutorial

This article mainly introduces how to get the object class name using javascript implementation similar to getClass () in java. The example shows how to use the getClass method in java implementation, which has some reference value, for more information about how to use javascript to get the object class name, see the example in this article. Share it with you for your reference. The details are as follows:

No function can return a specific type name in javascript.

For example, an object console. log (obj );
The result is [object HtmlTableCellElement]. If you want a function to return HtmlTableCellElement js, You can implement one by yourself without such a function by default.

var getObjectClass = function (obj) { if (obj && obj.constructor && obj.constructor.toString()) {   /*    * for browsers which have name property in the constructor    * of the object,such as chrome     */   if(obj.constructor.name) {    return obj.constructor.name;   }   var str = obj.constructor.toString();   /*    * executed if the return of object.constructor.toString() is     * "[object objectClass]"    */   if(str.charAt(0) == '[')   {     var arr = str.match(/\[\w+\s*(\w+)\]/);   } else {     /*      * executed if the return of object.constructor.toString() is       * "function objectClass () {}"      * for IE Firefox      */     var arr = str.match(/function\s*(\w+)/);   }   if (arr && arr.length == 2) {      return arr[1];   }  }  return undefined; };

I hope this article will help you design javascript programs.
