This time I will bring you the differences between iframe and frame in HTML, and what are the precautions for using iframe and frame in HTML. The following is a practical case, let's take a look.
I don’t know if you have used the frameset attribute in your project. I used the frameset attribute last year in the production of an online customer service system, because the customer service system needs to have a fixed layout, with one block on top, one block on the bottom, etc. Wait, frameset and frame were used at that time. After I used these attributes, I understood the difference between iframe and frame. Because before this, I generally didn’t use frames in my projects, and if I did, I would use iframes.
Let’s talk about the specific differences! The following points are summarized.
1. Frame cannot be used independently from frameSet, iframe can be used;
2. Frame cannot be placed in body;
It can be displayed normally as follows:
<!--<body>--> <frameset rows="50%,*"> <frame name="frame1" src="test1.htm"/> <frame name="frame2" src="test2.htm"/> </frameset> <!--<body>-->
The following cannot be displayed normally:
<body> <frameset rows="50%,*"> <frame name="frame1" src="test1.htm"/> <frame name="frame2" src="test2.htm"/> </frameset> <body>
On the contrary, if the iframe is placed under the frameSet attribute, it must be placed in the body
<body>
<frameset>
<iframe name="frame1" src="test1.htm"/>
<iframe name="frame2" src="test2.htm"/>
</frameset>
</body>3. iframe is an html tag, anywhere in html, Both can be used at will, but frame cannot.
<body> <iframe name="frame1" src="test1.htm"/> <iframe name="frame2" src="test2.htm"/> </body> <table> <tr> <td><iframe id="" src=""></iframe></td><td></td> </tr> </table>
The frame must be nested in the frameSet and cannot be used in tags such as table.
4. The height of the frame can only be controlled through frameSet; iframe can be controlled by itself, but cannot be controlled through frameSet
<!--<body>--> <frameset rows="50%,*"> <frame name="frame1" src="test1.htm"/> <frame name="frame2" src="test2.htm"/> </frameset> <!--</body>--> <body> <frameset> <iframe height="30%" name="frame1" src="test1.htm"/> <iframe height="100" name="frame2" src="test2.htm"/> </frameset> </body>
5. If more than two iframes are used on the same page, in IE can be displayed normally, but only the first one can be displayed in firefox; using more than two frames can be displayed normally in both IE and firefox
