Q: Is there a function of testing a client system, such as the system used by the user is a traditional system or a Simplified system, or the function of the test client's area settings !! I only know that in addition to getting client browser information in ASP, you can also get system / version with JScript Navigator objects.

Ask a master how to solve it? ? The parameter variable type of the pass value is not defined, you are passing as a variable, and this variable is not defined, the runtime will capture this error, plus quotation marks, as a constant, will not report error Q: Ask for simple and efficient judgment IE version of JS With (Navigator) {alert (appname == "Microsoft Internet Explorer" && paraSeint (appversion) == 4); Q: How do I determine whether XMLHTTP successfully reads the content of the webpage?
