Interview Questions

This is an interview with Sohu Javascript. The requirements are as follows:

Implements a URI parsing method to resolve the # parameter in the URL to the specified data structure.

 Function  Urlparser (s ){  //  ++ Answer area ++                          //  ++  }  Try  {  VaR Url1 = "http://www.abc.com/m/s/#page/2? Type = latest_videos & page_size = 20" ;  VaR Url2 = "http://www.abc.com/m/s/#type=latest_videos&page_size=20" ;  VaR Url3 = "http://www.abc.com/m/s/#page? Type = latest_videos & page_size = 20" ; Console. Group (); console.info (urlparser (url1); console.info (urlparser (url2); console.info (urlparser (url3); console. groupend ();  /*  ------ [Execution result] ------ ["page", "2", {"type": "latest_videos", "page_size": 20}] [{"type ": "latest_videos", "page_size": 20}] ["page", {"type": "latest_videos", "page_size": 20}] ----------------  */  } Catch  (E) {console. Error ( "Execution error, error message:" + E );} 

Analysis Process

This question is based on the test, and there is no good analysis.CodeRight.

 Function  Urlparser (s ){  //  ++ Answer area ++      VaR Marr = [];  VaR Parr = [];  VaR M = S. Split ("#") [1], P = "" ; If (M. indexof ("? ")>-1 ){  VaR Temp = M. Split ("? ") [0 ]; P = M. Split ("? ") [1 ]; Marr = Temp. Split ("/" );  If (Marr [Marr. Length-1] = "" ) {Marr. Pop ();}}  Else  {P = M;} Parr = P. Split ("&" ); VaR STR = "[" ;  For ( VaR I = 0, L = Marr. length; I <L; I ++ ) {Str + = "\" "+ Marr [I] + "\"," ;} Str + = "{" ;  For ( VaR I = 0, L = Parr. length; I <L; I ++ ) {Str + = "\" "+ Parr [I]. Split (" = "). Join (" \ ": \" ") + "\"," ;} Str + = "}]" ; Return Str. Replace (",}]", "}]" );  //  ++ }

Summary

This question examines the basic knowledge of JavaScript, such as string segmentation and connection. It is a simple question. Of course, you can also write high-quality code for simple questions.
