使用 JQuery 將 Javascript 動態注入 iframe

Question

我正在嘗試找到一種動態加載 Google 可視化 API 表的方法，該表從動態查詢到 Google 電子表格中填充到 Blogger 博客文章中。

不幸的是，博客樣式表似乎破壞了表格的樣式，所以我想我會嘗試將動態加載的表格注入 iframe 並將其與主機頁面隔離：

<script type="text/javascript" src="http://www.google.com/jsapi"></script>

<script type="text/javascript">
google.load("jquery", "1.3.2");
google.setOnLoadCallback(f1dj_iframeloader);
function f1dj_iframeloader(){
  $(function() {var $frame = $('iframe');
  setTimeout( function() {
    var doc = $frame[0].contentWindow.document;
    var $body = $('body',doc);
    $body.html("<script type='text/javascript' src='http://www.google.com/jsapi'></script><script type='text/javascript'>var f1dj_sskey="tQQIIA7x9VuyVKE7UVdrytg";var f1dj_sheet=8;var f1dj_authkey='CITwr80K';google.load('visualization', '1', {'packages':['table']});function f1dj_getData(){var url='http://spreadsheets.google.com/tq?tq=select%20*&key='+f1dj_sskey+'&authkey='+f1dj_authkey+'&gid='+f1dj_sheet;var query = new google.visualization.Query(url); query.send(f1dj_displayTable);} function f1dj_displayTable(response){if (response.isError()) return;var data = response.getDataTable(); visualization = new google.visualization.Table(document.getElementById('f1dj__table'));visualization.draw(data, null);} google.setOnLoadCallback(f1dj_getData)</script><div id='f1dj__table'></div>");}, 1 );
  });
}</script>

這似乎在一個簡單的 HTML 文本頁面中工作正常，除了：

1）在測試頁面中， ");}, 1 );});} 也呈現在頁面上（所以顯然有些不對勁......）

2) Blogger HTML 編輯器/解析器拋出解析錯誤並阻止頁面的保存（可能與 1 中的問題相同）

任何想法如何解決這一問題？ 有沒有什么明顯的我錯過了？:-(

Answer 1

您的引號不匹配 - fldj_sskey=... 的雙引號正在關閉傳遞給 $body.html 的字符串。

然后您的腳本標簽中的字符串中的“</script>”未編碼，因此 HTML 解析器認為腳本標簽到此結束。 你必須小心內聯 js 並且真的應該 html 編碼它...

Answer 2

這條線是你的問題：

$body.html("<script type='text/javascript' src='http://www.google.com/jsapi'></script><script type='text/javascript'>var f1dj_sskey="tQQIIA7x9VuyVKE7UVdrytg";var f1dj_sheet=8;var f1dj_authkey='CITwr80K';google.load('visualization', '1', {'packages':['table']});function f1dj_getData(){var url='http://spreadsheets.google.com/tq?tq=select%20*&key='+f1dj_sskey+'&authkey='+f1dj_authkey+'&gid='+f1dj_sheet;var query = new google.visualization.Query(url); query.send(f1dj_displayTable);} function f1dj_displayTable(response){if (response.isError()) return;var data = response.getDataTable(); visualization = new google.visualization.Table(document.getElementById('f1dj__table'));visualization.draw(data, null);} google.setOnLoadCallback(f1dj_getData)</script><div id='f1dj__table'></div>");}, 1 );

您正在使用雙引號 (") 中包含的字符串調用.html() ) 但在初始化f1dj_sskey變量時您的字符串包含雙引號。這意味着您的字符串將提前關閉。您需要更改字符串中的引號單引號，或者您需要轉義它們。

單引號（將"更改為' ）：

$body.html("<script type='text/javascript' src='http://www.google.com/jsapi'></script><script type='text/javascript'>var f1dj_sskey='tQQIIA7x9VuyVKE7UVdrytg';var f1dj_sheet=8;var f1dj_authkey='CITwr80K';google.load('visualization', '1', {'packages':['table']});function f1dj_getData(){var url='http://spreadsheets.google.com/tq?tq=select%20*&key='+f1dj_sskey+'&authkey='+f1dj_authkey+'&gid='+f1dj_sheet;var query = new google.visualization.Query(url); query.send(f1dj_displayTable);} function f1dj_displayTable(response){if (response.isError()) return;var data = response.getDataTable(); visualization = new google.visualization.Table(document.getElementById('f1dj__table'));visualization.draw(data, null);} google.setOnLoadCallback(f1dj_getData)</script><div id='f1dj__table'></div>");}, 1 );

Escaping（將"改為\" ）：

$body.html("<script type='text/javascript' src='http://www.google.com/jsapi'></script><script type='text/javascript'>var f1dj_sskey=\"tQQIIA7x9VuyVKE7UVdrytg\";var f1dj_sheet=8;var f1dj_authkey='CITwr80K';google.load('visualization', '1', {'packages':['table']});function f1dj_getData(){var url='http://spreadsheets.google.com/tq?tq=select%20*&key='+f1dj_sskey+'&authkey='+f1dj_authkey+'&gid='+f1dj_sheet;var query = new google.visualization.Query(url); query.send(f1dj_displayTable);} function f1dj_displayTable(response){if (response.isError()) return;var data = response.getDataTable(); visualization = new google.visualization.Table(document.getElementById('f1dj__table'));visualization.draw(data, null);} google.setOnLoadCallback(f1dj_getData)</script><div id='f1dj__table'></div>");}, 1 );
