問題描述

我正在嘗試在彈出窗口中格式化這行代碼，但我遇到了 unterminated string literal 錯誤.

I am trying to format this line of code in my popup window, but i am facing unterminated string literal error.

誰能告訴我如何最好地格式化它.

Can somebody please tell me how best I could format this.

window.setTimeout("winId.document.write('<script src="../js/tiny_mce/tiny_mce.js" type="text/javascript"></script>
')", 10);

還要指出這行代碼在彈出窗口中是否可以正常工作?

Also point out if this particular line of code would work fine in the popup?

推薦答案

最好不要使用字符串，而是使用匿名函數:

Best not to use a string, but an anonymous function instead:

window.setTimeout(function () {
    winId.document.write(
      '<script src="../js/tiny_mce/tiny_mce.js" type="text/javascript"></script>
'
    );
}, 10);

在 setTimeout 和 setInterval 中使用字符串與 eval() 密切相關，應僅在極少數情況下使用.請參閱 http://dev.opera.com/articles/view/高效的javascript/?page=2

Using strings in setTimeout and setInterval is closely related to eval(), and should only be used in rare cases. See http://dev.opera.com/articles/view/efficient-javascript/?page=2

還可能值得注意的是，document.write() 將無法在已解析的文檔上正常工作.不同的瀏覽器會給出不同的結果，大多數會清除內容.另一種方法是使用 DOM 添加腳本:

It might also be worth noting that document.write() will not work correctly on an already parsed document. Different browsers will give different results, most will clear the contents. The alternative is to add the script using the DOM:

window.setTimeout(function () {
    var winDoc = winId.document;
    var sEl = winDoc.createElement("script");
    sEl.src = "../js/tiny_mce/tiny_mce.js";
    winDoc.getElementsByTagName("head")[0].appendChild(sEL);
}, 10);
