JavaScript gets the parameters in the current URL

JavaScript gets the parameters in the current page URL can use the search method of location, get to the URL? The following sections, such as Http:localhost:8080/manager/index.jsp?id=1

Use the search method of location to get to the string? id=1; want to get? The following key-value pairs can be intercepted using the substring method, get id=1 after interception, obtain the value of the ID, you can split it using the Split () method, and split the expression to "=". Here's a look at the specific example:

Window.onload = function () {var param = location.search.substring (1); var results = param.split ("="); var result = Results[1 ];if (result== "-1") {alert ("id value is-1");} else if (result = = "1") {alert ("id value is 1");} else if (result = = "2") {alert ("ID value is 2");}};

If there are multiple parameters in the URL, that is, each parameter uses & to split, then we get to? The subsequent string can be split with split first, split the expression to &, and then get the array to split each string. To get each parameter.
