当我将变量 strJSON 中的 JSON 传递给

var data = new google.visualization.DataTable(strJSON);

它给了我错误JavaScript runtime error: Invalid JSON string:.我已经在jsonlint上验证了上述JSON,但是谷歌js给出了错误。

三件事:

首先,如果您将其作为使用单引号的字符串文字包含在 JSON 代码中(也就是说,您不是通过 AJAX 加载它,而是作为脚本中的实际字符串块(,则应确保转义所有换行符(将它们替换为 'n (和所有单引号(将它们替换为 '' (。字符串中的换行符必须转义,因为 JS 将换行符解释为语句的结尾,这意味着您将打开字符串文字而不关闭它。如果您的字符串包含与包装它的引号字符相同的引号字符,则需要对其进行转义,因为这会过早关闭字符串文字。

其次,我不知道你为什么要在字符串中转义空格、句点和大括号。我无法想象这会如何帮助或伤害你。

第三,看起来你正在以SQL的风格转义单引号。这可能是有原因的,但同样,我想不出它会如何帮助你(如果你认为它会保护你免受SQL注入或类似的东西的影响,那么你可能有更深层次的问题(。

根据您在下面的评论,我建议使用Microsoft为您提供的JavaScript序列化工具。

此外,如果您使用任何不安全的内容(例如,用户生成的内容或来自您控制范围之外的任何内容(,则应确保所有内容都经过JSON.parse()。否则,您将面临 XSS 攻击。例如:

var objJSON = JSON.parse(strJSON),
    data = new google.visualization.DataTable(objJSON);
