你不能再使用的ID ......他們必須在每一頁上是唯一的。 –

與此類似，其中I加入一個包裝div來設置的字體大小，從校正的語法錯誤...style.font-size至...style.fontSize並刪除重複的ID（因爲它們應該是唯一的）。

function textSizeS(){ 
 
    document.getElementById("MaintblWrapper").style.fontSize = "3px"; 
 
} 
 

 
function textSizeM(){ 
 
    document.getElementById("MaintblWrapper").style.fontSize = "26px"; 
 
} 
 

 
function textSizeL(){ 
 
    document.getElementById("MaintblWrapper").style.fontSize = "45px"; 
 
}
