I want to get in ColdFusion 10 an URL parameter from CGI.QUERY_STRING by its name. How to do it without looping?

推荐答案

通过查询字符串传递到页面的任何值都可以在URL范围内使用.

Any values passed in to a page via the query string are available in the URL scope.

假设您有一个类似于http://mydomain.com?val1=42&val2=moo的查询字符串，则可以通过这样引用它们来访问变量

Assume you have a query string that looks like http://mydomain.com?val1=42&val2=moo you would access the variables by referencing them as such

<cfset myVal1 = url.val1 />
<cfset myVal2 = url.val2 />

或者，在cfscript中

Or, in cfscript

myVal1 = url.val1;
myVal2 = url.val2;

要查看通过查询字符串传入的所有值，还可以转储URL范围.

To see all the values passed in via query string, you can also dump out the URL scope.

<cfdump var="#url#" />

或者，在cfscript中

or, in cfscript

writeDump( url );
