使用函數輸出調用javascript函數的問題

下面的代碼中的問題是從另一個函數調用一個函數 - 函數domenu調用doarticle和相關的頁碼OK，但doarticle函數根本不用CSS格式化。如果我獨立地調用函數而不是一切正常，那只有當我從另一個調用一個問題出現時纔會調用它。使用函數輸出調用javascript函數的問題

使用FIREBUG監控CSS：當doarticle函數被調用時，所有CSS數據都從DOM消失。

你應該寫：

hhgselect = dmenu(numrows);

然後

doarticle(hhgselect);

編輯：或者如果你想在onclick上選擇，爲什麼不直接在onclick事件中調用doarticle？

編輯2：

嘗試：

... hhgstring + "<td><span id=\"menutitle\" onclick=\"doarticle('" +recnum+ "');\">"...

編輯3：

<script type="text/javascript"> 
function domenu (lastrecord) 
{ 
    hhgstring = "<br/><br/><table border=\"0\" cellpadding=\"0\">"; 
    for (counter=1; counter<lastrecord; counter++) 
    { 
     recnum = lastrecord - counter; 
     // hhgstring = hhgstring + "<tr><td><img class=\"imgpadded\" src=\"" +  imgpath + hhgdata[recnum][4] + "\" align=\"left\"></td>"; 
     hhgstring = hhgstring + "<tr><td>" + hhgdata[recnum][4] + "</td>"; 
     hhgstring = hhgstring + "<td><span class=\"menutitle\" onclick=\"doarticle('" +recnum+ "');\">" + tab + hhgdata[recnum][1] + "<br/></span>"; 
     hhgstring = hhgstring + "<span class=\"menusummary\">" + tab + hhgdata[recnum][3] + "</span></td></tr>"; 
    } 
hhgstring = hhgstring + "</table>"; 
document.write(hhgstring); 
return(hhgselect); 
} 
</script> 

</head> 
<body> 

<script type="text/javascript"> 
    imgpath = "images/"+imgmod+"/"; 
    tab = "&nbsp;&nbsp;&nbsp;&nbsp;"; 
    hhgselect = 0; 
    domenu (numrows); 
</script>

當我打電話做文章的點擊事件時，它失去了頁面上CSS的所有訪問 - 我不知道爲什麼...... – TJS101

首先嚐試使用DOM createElement和appendChild它更有用，其次請驗證如果你在一個帶參數的字符串內使用正確的調用（提示你應該使用很多轉義字符） – khael

嘗試了hhgselect = domenu（many）;方法。什麼都沒發生。 onclicks是好的還是有更好的方法來改變一個變量？ – TJS101

hhgselect不會出現在任何地方得到任何新的價值，因此，它是有道理的，它將保持爲0，並且您將始終看到相同的結果。

你認爲你在哪裏改變它的價值？這是一個全局變量，你從domenu（）返回它，儘管它沒有被任何東西收集，正如我們已經說過的那樣。然而，不管它是否被收集，因爲你實際上並沒有修改它的價值，所以沒有理由被使用。
