Chamar variaveis via iframe

offday · Abril 25, 2015

Pessoal, tenho uma duvida que talvez seja básica, vamos la:

Tenho um script js de um contador regressivo, que fica em um arquivo html (codigo abaixo)

<html>
<head>
<style type="text/css">
.numbers {
    border-style: ridge;    /* options are none, dotted, dashed, solid, double, groove, ridge, inset, outset */
    border-width: 2px;
    border-color: #666666;  /* change the border color using the hexadecimal color codes for HTML */
    background: #222222;    /* change the background color using the hexadecimal color codes for HTML */
    padding: 2px 0px;
    width: 55px;
    text-align: center; 
    font-family: Arial; 
    font-size: 28px;
    font-weight: bold;    /* options are normal, bold, bolder, lighter */
    font-style: normal;   /* options are normal or italic */
    color: #FFFFFF;       /* change color using the hexadecimal color codes for HTML */
}
.title {    /* the styles below will affect the title under the numbers, i.e., “Days”, “Hours”, etc. */
    border: none;    
    padding: 0px;
    width: 55px;
    text-align: center; 
    font-family: Arial; 
    font-size: 10px; 
    font-weight: normal;  /* options are normal, bold, bolder, lighter */
    color: #DDDDDD;       /* change color using the hexadecimal color codes for HTML */
    background: transparent;    /* change the background color using the hexadecimal color codes for HTML */
}
#table {
    width: 400px;
    border: none;    /* options are none, dotted, dashed, solid, double, groove, ridge, inset, outset */
    margin: 0px auto;
    position: relative;    /* leave as "relative" to keep timer centered on your page, or change to "absolute" then change the values of the "top" and "left" properties to position the timer */
    top: 0px;        /* change to position the timer */
    left: 0px;       /* change to position the timer; delete this property and it's value to keep timer centered on page */
}
</style>

<script type="text/javascript">

    var futurestring1=(montharray[m-1]+" "+d+", "+yr+" "+hr+":"+min);
    var futurestring=Date.parse(futurestring1)-(today.getTimezoneOffset()*(1000*60));
    var dd=futurestring-todaystring;
    var dday=Math.floor(dd/(60*60*1000*24)*1);
    var dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1);

    if(dday<=0&&dhour<=0&&dmin<=0&&dsec<=0){
        document.getElementById('count2').innerHTML=current;

        return;
    }
    else {
        document.getElementById('count2').style.display="none";
        document.getElementById('dday').innerHTML=dday;
        document.getElementById('dhour').innerHTML=dhour;
        document.getElementById('dmin').innerHTML=dmin;
        document.getElementById('dsec').innerHTML=dsec;
        setTimeout("countdown(theyear,themonth,theday,thehour,theminute)",1000);
    }
}
</script>

</head>

<body onload="countdown(year,month,day,hour,minute)">
<table id="table" border="0">
    <tr>
        <td align="center" colspan="6"><div class="numbers" id="count2" style="padding: 10px; "></div></td>
    </tr>
    <tr id="spacer1">
        <td align="center" ><div class="title" ></div></td>
        <td align="center" ><div class="numbers" id="dday"></div></td>
        <td align="center" ><div class="numbers" id="dhour"></div></td>
        <td align="center" ><div class="numbers" id="dmin"></div></td>
        <td align="center" ><div class="numbers" id="dsec"></div></td>
        <td align="center" ><div class="title" ></div></td>
    </tr>
    <tr id="spacer2">
        <td align="center" ><div class="title" ></div></td>
        <td align="center" ><div class="title" id="days">Days</div></td>
        <td align="center" ><div class="title" id="hours">Hours</div></td>
        <td align="center" ><div class="title" id="minutes">Minutes</div></td>
        <td align="center" ><div class="title" id="seconds">Seconds</div></td>
        <td align="center" ><div class="title" ></div></td>
    </tr>
</table>

</body>
</html>

E chamo ele de outra pargina a partir de um iframe:

<iframe id="timer1" src="timer1.html" width="412" height="76" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" allowTransparency="true" style="position: absolute; top: 10px; left: 100px; overflow: hidden;" ></iframe>

Porém, eu gostaria de modificar as variaveis:

var year=

var month=;
var day=

Que estao no primeiro codigo. Eu queria chama-las pelo iframe, ou seja, poderia modificar o valor delas diretamente pelo iframe. alguém saberia dizer como faço isso?
