What should I fill out in a JSP page, such as SRC, of an IFRAME? Can it be HTML, JSP, servlet, action? How is it loaded?

If there is a test project, there is an IFRAME in one of its jsps, the code is as follows:

<div class= "TC1" style= "padding-left:10px" >
<iframe src= "${contextpath}/main/getiframejsp" width= "Up" height= "120px" marginwidth= "1" marginheight= "1" name= " Test "id=" test "border=" 0 "frameborder=" 0 "></iframe>
</div>

The src of the IFRAME is: ${contextpath}/main, full link to http://127.0.0.1:8080/test/main/getIframeJsp

===1 can be HTML 2 can be a html== of other works

The src attribute specifies the URL of the document to display in the IFRAME.

Specifies the address of the document that is displayed in the IFRAME.

Possible values:

• Absolute URLs-point to other sites (such as src= "www.example.com/index.html")
• Relative URL-Points to a file within the site (e.g. src= "index.html")

= = = can be a project or other project, action, servlet==

Q: Can src in an iframe be a servlet, and then the servlet jumps to the JSP appear in the IFRAME? Answer: Yes.
Set the src= ' xxxxx/yyy.do ' of the IFRAME, in the corresponding servlet, similar to the following notation: Request.getrequestdispatcher ("/a/b.jsp"). Forward (Request, Response);

= = = Summary

As can be understood, SRC is a URL request, such as this: <div class= "TC1" style= "padding-left:10px" >
<iframe src= "${contextpath}/main/getiframejsp" width= "Up" height= "120px" marginwidth= "1" marginheight= "1" name= " Test "id=" test "border=" 0 "frameborder=" 0 "></iframe>
</div>

SRC is http://127.0.0.1:8080/test/main/getIframeJsp, and its execution process is followed by input in the browser http://127.0.0.1:8080/test/main/ GETIFRAMEJSP executes the same procedure, executes the getiframejsp method of the test engineering Mainaction class, and displays the execution results in the IFRAME location.
