當頁面通過URL來傳遞參數時(page.html?id=123&name=aaa),可以在包含swf的html網頁中先用javascript從url中截取包含參數的字串,以FlashVar的形式傳給swf,而在Flex中可以直接使用this.parameters.參數名來擷取參數的值.
Sample:
html頁面代碼:
<html>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"> ");
document.write("<param name="allowScriptAccess" value="sameDomain" /> ");
document.write("<param name="movie" value="useLib.swf" /> ");
document.write("<param name="FlashVars" value=""+ parastr +"" /> ");
document.write("<param name="quality" value="high" /> ");
document.write("<param name="bgcolor" value="#ffffff" /> ");
document.write("<embed src="useLib.swf" quality="high" bgcolor="#ffffff" width="550" height="400" name="FlashVars" align="middle" allowScriptAccess="sameDomain" FlashVars=""+ parastr +"" type="application/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);
