js gets html parameters and transfers parameters to swf application introduction_javascript skills

We know that HTML pages are executed on the client side, so client-side scripts (such as JavaScript) must be used to obtain parameters. This is different from the way server-side scripts obtain parameters.

The following js code obtains all the parameters after the "?" of the HTML web page.

Copy code The code is as follows:

1. The following js code can obtain a certain parameter of the HTML web page in more detail

Copy code The code is as follows:

2. Pass to swf in HTML web page Parameters
Method 1: Use js in the web page, SetVariable to set the variables in the flashobject, the code is as follows:

Copy code The code is as follows:

// "HtmlToSwf" is the flashobject ID in the web page
HtmlToSwf.SetVariable("_root.info_str", "Happy Newyear");

Method 2: Path parameters, such as test.swf?foo=happy2005
Method 3: Use FlashVars. The following mainly introduces the usage of FlashVars. The flashobject code embedded in HTML after using FlashVars is as follows:

Copy code The code is as follows:

< object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0 " width="550" height="400" id="FlashVars" align="middle"> string 5

< param name="movie" value="FlashVars.swf" />

By the above code , you can directly obtain foo, program, and language variable data in SWF (FlashVars.swf). The code for FlashVars.fla to obtain the FlashVars parameters is as follows:

Copy code The code is as follows:

// Create three text fields
_root.createTextField("foo_txt",1,0,0,16,16);
_root.createTextField("program_txt",2,0,32,16,16);
_root.createTextField("language_txt",3,0,64,16,16);
foo_txt.autoSize = true;
String 8
foo_txt.border = true;
program_txt. autoSize = true;
program_txt.border = true;
language_txt.autoSize = true;
language_txt.border = true;
// Get FlashVars variable
foo_txt.text = "in HTML foo parameter: " foo;
program_txt.text = "program parameter in HTML:" program;
language_txt.text = "language parameter in HTML:" language;

3. 두 가지의 효과적인 결합
js를 사용하여 HTML 웹페이지에서 매개변수를 얻은 다음, 얻은 매개변수를 FlashVars로 flashobject에 작성하고 swf에 전달합니다. 코드는 다음과 같습니다.
