JS access to HTML parameters and transfer parameters to SWF application introduction _javascript Skills

We know that HTML pages are executed on the client side, so that the parameters must be obtained using client script (such as JavaScript), which differs from the server-side script fetching parameters.

The following JS code to get HTML page shape such as "Test.html?foo=mytest&program=flash" "?" After all the parameters.

Copy Code code as follows:

<script language=javascript>
<!--
var hrefstr,pos,parastr;
Hrefstr = window.location.href;
pos = Hrefstr.indexof ("?");
Parastr = hrefstr.substring (pos 1);
if (pos>0) {
document.write ("All Parameters:" PARASTR);
} else {
document.write ("no parameters");
}
-->
</script>

one, the following JS code can be more detailed to get an HTML page of a parameter

Copy Code code as follows:

<script language=javascript>
<!--
function Getparastr (strname) {
var hrefstr,pos,parastr,para,tempstr;
Hrefstr = window.location.href;
pos = Hrefstr.indexof ("?") String 9
Parastr = hrefstr.substring (pos 1);
Para = Parastr.split ("&");
Tempstr= "";
for (I=0;i<para.length;i)
{
TempStr = Para[i];
pos = tempstr.indexof ("=");
if (tempstr.substring (0,pos) = = strname) {
Return tempstr.substring (POS 1);
}
}
return null;
}
Get program Parameters
var programstr = getparastr ("program");
document.write (PROGRAMSTR);
-->
</script>

passing parameters to SWF in HTML Web pages
Method One: Use js,setvariable in the Web page to set the variables in Flashobject, such as:

Copy Code code as follows:

"Htmltoswf" is the Flashobject ID in the Web page
Htmltoswf.setvariable ("_root.info_str", "Happy newyear");

Method Two: Path parameters, such as test.swf?foo=happy2005
Method Three: Use Flashvars, the following mainly introduces the usage of flashvars. The Flashobject code for embedding HTML after using Flashvars is as follows:

Copy Code code 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=" "height=" id= "flashvars" align= "middle" > String 5
<param name= "allowscriptaccess" value= "Samedomain"/>
<param name= "movie" value= "flashvars.swf"/>
<param name= "Flashvars" value= "foo=happy2005&program=flash&language= Simplified Chinese-China"/>
<param name= "Quality" value= "High"/>
<param name= "bgcolor" value= "#ffffff"/>
<embed src= "flashvars.swf" quality= "High" bgcolor= "#ffffff" width= "" "height=" Name= "Flashvars" "align=" Middle "allowscriptaccess=" never "allownetworking=" internal "autostart=" 0 "flashvars=" foo=happy2005&program= flash&language= Simplified Chinese-China "type=" Application/x-shockwave-flash "pluginspage=" http://www.macromedia.com/go/ Getflashplayer "/>

With the above code, you can get Foo, program, and language variable data directly in SWF (FLASHVARS.SWF). Flashvars.fla the code to get the Flashvars parameter is as follows:

Copy Code code 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 = "Foo parameter in HTML:" foo;
Program_txt.text = "program parameters in HTML:" program;
Language_txt.text = "Language parameter in HTML:" language;

Iii. Effective combination of the two
Use JS in an HTML Web page to get parameters, and then pass the obtained arguments as Flashvars write flashobject to the SWF. The code is as follows:

Copy Code code as follows:

<script language=javascript>
<!--
function Writeflashobject (PARASTR) {
document.write ("<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\" \>\n ");
document.write ("<param name=\" allowscriptaccess\ "value=\" samedomain\ "/\>\n");
document.write ("<param name=\" movie\ "value=\" flashvars.swf\ "/\>\n"); String 2
document.write ("<param name=\" flashvars\ "value=\" "Parastr" \ "/\>\n");
document.write ("<param name=\" quality\ "value=\" high\ "/\>\n");
document.write ("<param name=\" bgcolor\ "value=\" #ffffff \ "/\>\n");
document.write ("<embed src=\" flashvars.swf\ "quality=\" high\ "bgcolor=\" #ffffff \ "width=\" 550\ "height=\" 400\ " Name=\ "flashvars\" align=\ "middle\" allowscriptaccess=\ "samedomain\" "flashvars=\" "Parastr" type=\ X-shockwave-flash\ "pluginspage=\" Http://www.macromedia.com/go/getflashplayer\ "/\>");
document.write ("</object\>");
}
function Getparastr () {
var hrefstr,pos,parastr,para,tempstr1;
Hrefstr = window.location.href;
pos = Hrefstr.indexof ("?")
Parastr = hrefstr.substring (pos 1);
return parastr;
}
var parastr = Getparastr ();
Writeflashobject (PARASTR);
-->
