当我将变量strJSON中的JSON传递给
时var data = new google.visualization.DataTable(strJSON);
它给了我错误JavaScript runtime error: Invalid JSON string:
。我已经在jsonlint上验证了上面的JSON,但google js给出了错误。
答案 0 :(得分:1)
三件事:
首先,如果您使用单引号将此作为字符串文字包含在您的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),您应该确保您正在转义所有换行符(将其替换为\n
)和所有单引号(将其替换为\'
)。字符串中的换行符必须进行转义,因为JS将换行符解释为语句的结尾,这意味着您将打开一个字符串文字而不关闭它。如果你的字符串包含与包装它相同的引号字符,则需要对其进行转义,因为这会过早地关闭字符串文字。
其次,我不知道你为什么要逃避字符串中的空格,句号和括号。我无法想象这会对你有什么帮助或伤害。
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,我无法想象它会如何帮助你(如果你认为它会保护你免受SQL注入或类似的事情,那么你可能有更深层次的问题)。

根据您在下面的评论,我建议您使用Microsoft为JavaScript serialisation提供的工具。
此外,如果您使用任何不安全的内容(例如,用户生成的内容或源自您控件之外的任何内容),您应该确保所有内容都通过JSON.parse()
。否则,你会对XSS攻击持开放态度。例如:
var objJSON = JSON.parse(strJSON),
data = new google.visualization.DataTable(objJSON);
