how to read cgi file by javascript

Question

如何在javascript中使用CGI程序的输出？

Answer 1

您读取任何其他服务器页面的方式相同：AJAX。

Answer 2

If your cgi file is placed inside web root directory, you can use Ajax to receive its content. jQuery sample:

var cgiContent ='';
$.get('cgi-bin/my.cgi', function(data) {
    cgiContent = data;
});

Answer 3

You can have your cgi output javascript commands in text and then include its output as you would include any other javascript file.

CGI Example in Python:

print("Content-Type: text/plain")
print

print("var value = 'Hello World';")             

Then include this in your HTML page:

<script type="text/javascript" src="/path/to/cgi/script.py"></script>
<script type="text/javascript"> document.write(value)</script>
