JavaScript code loading optimization method_javascript skills

Below we introduce a simpler method through this example:

We save the statistical code to a file: File path:/config/counter.conf

The statistical code is as follows:

Copy code The code is as follows:

We use StreamReader to convert the file The content is read out, and the code will not be listed in detail

We need a page to output this javascript code:

Page:/do.ashx?args=GetCounter

Copy code The code is as follows:

string code = "Read statistical code";
code = Regex. Replace(code, "[']",""");
code = Regex.Replace(code, "[nr]", "");
context.Response.Write("document.write( '" code "');");

In this way, the output javascript can be added to the page to achieve statistical functions!

We only need to reference the javascript file on the web page Add the following code:

Copy the code The code is as follows:

var _s=document.createElement( 'script');
_s.type='text/javascript';
_s.src='/do.ashx?args=GetCounter';
var _fs=document.getElementsByTagName("script") [0];
_fs.parentNode.insertBefore(_s,_fs);

You’re done, the statistics code will not be displayed in your webpage, but it has actually been loaded into your webpage !
