Javascript shares a method to obtain the urlget parameter.

We often see that some url links are followed by parameters. Sometimes we need to obtain these url parameters for use in development. This article introduces a method to obtain the urlget parameter. For more information about the coders, see. This function uses the indexOf method and split method in javascript. The Code is as follows:

Function getPara (para) {if (location. href. indexOf ("? ") =-1) {// if there is no parameter, Do nothing. return null;} else {// GET request? Var urlQuery = location. href. split ("? "); If (urlQuery [1]. indexOf ("&") =-1) {// there is only one parameter if (urlQuery [1]. indexOf ("=") =-1) {// no equal sign, no parameter, Do nothing return null;} else {var keyValue = urlQuery [1]. split ("="); var key = keyValue [0]; var value = keyValue [1]; if (key = para) {return value ;}}} else {// resolution parameter var urlTerms = urlQuery [1]. split ("&"); for (var I = 0; I <urlTerms. length; I ++) {var keyValue = urlTerms [I]. split ("="); var key = keyValue [0]; var value = keyValue [1]; if (key = para) {return value ;}}}} return null ;}

You can directly call the getPara function to obtain the parameters of a url.
