Flash embedded in html Solution for embedding Flash files in html web page code (Part 1) _HTML/Xhtml_Web page production
It is the custom of the Chinese people to celebrate the New Year before the fifteenth day of the first lunar month. Here I would like to wish your friends in the garden a happy new year.
In the past few days, the company's website homepage needs to be revised. After the company's "staff reduction" at the end of last year, one person has to do the work of multiple people, and suddenly he feels that the burden is heavy. No, this is not something within the scope of my work. Unfortunately, I have been involved in it. Fortunately among the misfortunes, the task assigned to me by BOSS this time is exactly the front-end development task I have always been passionate about. I have been engaged in the development of back-end management programs for the company's website before, mostly processing business logic on the server side. I have never had the opportunity to put my skills into use in front-end development, which I am passionate about. Practice is the best way to test true knowledge. Solving the practical tasks assigned to me is a rare test. I learned a lot of scattered knowledge through books and various materials, but did not get the opportunity to combine them together. Comprehensive test”, haha. There are so many ink stains on the front, which are caused by suppressing them for a long time, haha.
Let me first describe the task requirements: There is a JPG picture composed of five balls on the homepage of the company's website. It is used for navigation. Clicking on the text on each ball will open the corresponding information. On the secondary page, there is an almost identical Flash version corresponding to the image. One of the tasks assigned to me by my boss is: when the client browser has a Flash file player installed, the Flash version of the navigation is displayed, and vice versa, the JPG image navigation is displayed. After getting the task, think about it for a moment. As a front-end development, of course you have to consider browser compatibility issues. The best way to bridge the gap between browsers is to use one or more mature JavaScript frameworks. Fortunately, there happens to be one A very mature and sophisticated JS framework exists, named: SWFObject.js.
The first time I came into contact with SWFObject.js was its V1.5, and this time I used V2.1 to solve the problem. There are still some differences in the use of the two. Overall, I feel that V2.1 is a big leap forward compared to V1.5. V2.1 is more in line with the object-oriented JavaScript programming style in terms of the source code of the framework and the usage process.
I will take you to experience this "tortuous" journey from the perspective of a researcher who has just explored JavaScript. Whether you are a novice like me, or you are already proficient in writing various JS As a veteran of coding, please be merciful and hope that everyone can point out the short-sightedness in my thinking and the errors in my writing in a civilized manner.
The following code is an example of usage that I adapted from a documentation of SWFObject V1.5 (if you want to learn more about V1.5, please click this link):
If you execute the above code, you will find that this picture is still displayed on the page
, and a warning box containing "The element does not exist" will pop up. It seems that the problem is not caused by external loading. swfobject_source.js file. If you see this, you will definitely experience my annoyance at that time. After taking a short rest, I cleared my mind and looked back, only to find that the essence of the problem lies in "HTML DOM loading". In a page, JS scripts in the head of the page (that is, between ) and JS files loaded from external files will be executed before the HTML DOM is actually constructed. Therefore, the scripts executed in these two places cannot access the DOM that does not yet exist. You should know the real reason, which is that during the execution of the JS code in Example 1.1, the
Okay, after seeing this, there is one last step that you need to do yourself, which is to simply modify the above code and adopt an inelegant method to solve it
About "HTML DOM" "Loading" problem, which method is it? I think you may have guessed it. Yes, it is exactly the following method:
