JavaScript gets the number of references in the current URL

JavaScript gets the number of references in the current page URL can use the search method of location, get to the URL? The latter part, like 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, obtained id=1 after interception, the value of the ID must be obtained, can be split using the split () method, and the split expression is "=". See the detailed example below:

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");}};

Assume that there are multiple parameters in the URL. That is, we use & to cut in each of the parameters, and then we get it? The subsequent string can be split with split first. Splits the expression to &, and then gets the array in which each string is cut. You can get each of the parameters.
