未捕獲的SyntaxError：意外的標記非法

我收到未捕獲的SyntaxError：意外的令牌鉻非法使用此代碼：未捕獲的SyntaxError：意外的標記非法

var leftMiddleJS = 'function onmouseover() { 
     document.getElementById("background").style.marginTop = "-135px"; 
     document.getElementById("background").style.marginLeft = "0px"; 
     document.getElementById("background").style.width = "760px"; 
     document.getElementById("background").style.height = "520px"; 
     document.getElementById("background").style.marginTop = "0"; 
     document.getElementById("background").style.marginLeft = "0"; 

     function click() { 
     document.getElementById("outsideContainer").style.marginTop = "0"; 
     document.getElementById("outsideContainer").style.marginLeft = "0"; 
     document.getElementById("outsideContainer").style.width = "300px"; 
     document.getElementById("outsideContainer").style.height = "250px"; 
     document.getElementById("insideContainer").style.marginTop = "-135px"; 
     document.getElementById("insideContainer").style.marginLeft = "0px"; }';

什麼是代碼中的問題？

它的說法是在第一行 – user2958098

缺少'}''後的document.getElementById（「背景」）。 style.marginLeft =「0」;' –

你在做什麼函數declration''function' onmouseover（） –

如果你想分配跨多行的字符串 - 使用\字符串延續：

var leftMiddleJS = 'function onmouseover() { \ 
     document.getElementById("background").style.marginTop = "-135px"; \ 
     document.getElementById("background").style.marginLeft = "0px"; \ 
     document.getElementById("background").style.width = "760px"; \ 
     document.getElementById("background").style.height = "520px"; \ 
     document.getElementById("background").style.marginTop = "0"; \ 
     document.getElementById("background").style.marginLeft = "0"; \ 
\ 
     function click() { \ 
     document.getElementById("outsideContainer").style.marginTop = "0"; \ 
     document.getElementById("outsideContainer").style.marginLeft = "0"; \ 
     document.getElementById("outsideContainer").style.width = "300px"; \ 
     document.getElementById("outsideContainer").style.height = "250px"; \ 
     document.getElementById("insideContainer").style.marginTop = "-135px"; \ 
     document.getElementById("insideContainer").style.marginLeft = "0px"; }';
