Question

我有當我點擊計算按鈕

<script type="text/javascript"> 
function ln(){ 
document.getElementById('looknorth').innerHTML='<embed bgcolor="#dbdbd3" flashvars="lcId=1169793726234&amp;state=symbol%3D%5Ensebank;range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined" loop="false" menu="false" name="BANKNIFTY" pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://us.js2.yimg.com/us.yimg.com/i/us/fi/yfc/swf/flashchart_1.18.swf" style="height: 775px; width: 550px" type="application/x-shockwave-flash" wmode="opaque"></embed>'; 
    }  
</script> 
<input type=button style="background-color:#123742; color:#FFFFFF ; font-weight:bold; font-size:15" name=Button2 value=Calculate onClick=ln();></td></tr> 

我想有一個drodown菜單這需要符號的值whhich被detting顯示嵌入式代碼「符號％3D ％5Ensebank;」從下拉菜單的值。

我添加的代碼

<select size="1" name="D1"> 
<option value="nsei" selected>Nifty</option> 
<option value="bsen">Sensex</option> 
</select><input type="submit" value="Submit" name="B1" onClick=ln();></p> 

，但什麼樣的變化在嵌入式代碼，以從D1取符號值

請幫助

<div id="looknorth"></div> 
<script type="text/javascript"> 
function ln(vidvar){ 

tempcell = document.createElement("embed"); 
tempcell.setAttribute("bgcolor","#dbdbd3"); 
tempcell.setAttribute("flashvars", 
("lcId=1169793726234&amp;state=symbol=" 
+vidvar+ 
";range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined") 
); 
tempcell.setAttribute("loop","false"); 
tempcell.setAttribute("menu","false"); 
tempcell.setAttribute("name","Bank Nifty"); 
tempcell.setAttribute("pluginspage","http://www.macromedia.com/go/getflashplayer"); 
tempcell.setAttribute("src","http://us.js2.yimg.com/us.yimg.com/i/us/fi/yfc/swf/flashchart_1.18.swf"); 
tempcell.setAttribute("style","height: 775px; width: 550px"); 
tempcell.setAttribute("type","application/x-shockwave-flash"); 
tempcell.setAttribute("wmode","opaque"); 


document.getElementById('looknorth').innerHTML="" 
document.getElementById('looknorth').appendChild(tempcell); 

}

<form name="Video" id="search" onsubmit="ln(search.D1.value)"> 

<select size="1" name="D1"> 
<option value="^nsei" selected>Nifty</option> 
<option value="^bsesn" >Sensex</option> 
</select> 

<input type="submit" value="Submit" name="B1" onClick=ln();> 

我試圖去掉代碼但仍然無法正常工作。請幫助

Answer 1

您需要將它們放在窗體標籤中。

<form name="Video" id="search" onsubmit="ln(search.D1.value)"> 

<select size="1" name="D1"> 
<option value="nsei" selected>Nifty</option> 
<option value="bsen" >Sensex</option> 
</select> 

<input type="submit" value="Submit" name="B1" /> 

</Form> 

然後，改變LN（），所以它需要一個變量，這樣也許嘗試：

<script type="text/javascript"> 
function ln(vidvar){ 

tempcell = document.createElement("embed"); 
tempcell.setAttribute("bgcolor","#dbdbd3"); 
tempcell.setAttribute("flashvars", 
    ("lcId=1169793726234&amp;state=" 
    +vidvar+ 
    ";range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined") 
    ); 
<!-- And so on for the rest of the attributes of the <embed> tag --> 
document.getElementById('looknorth').innerHTML="" 
document.getElementById('looknorth').appendChild(tempcell); 
    }  
</script> 

有可能是在此的一些bug但這是一般的想法。
