1、当用JSON.parse()方法，解析从后台传来的json字符串，而且字符串中含有单引号(如I'am ....)，页面将出现如下异常

2、页面引起报错部分

3、解决办法：在后台将特殊字符转义

bookBlockVoListJSONString = BaseStringUtils.getJsonForJS(JSONArray.fromObject(bookBlockVoList).toString());

--页面

//如果为做作业，则下面两个变量有值
var _homeworkRecordId = '${homeworkRecordId}';
var _homeworkType = '${homeworkType}';
var _blockList = null;
if( _homeworkRecordId != null && _homeworkRecordId != "" ){
_blockList = JSON.parse('${bookBlockVoListJSONString}');
}

4、转义代码

public class BaseStringUtils {

	/**
	 * 转换特殊字符，将json串转换为JS能直接识别的json
	 * @param oldJson
	 * @return
	 */
	public static String getJsonForJS(String oldJson) {
		
		String newJson = oldJson;
		newJson = newJson.replaceAll("\\\\","\\\\\\\\");
		newJson = newJson.replaceAll("\\'","\\\\'");
		newJson = newJson.replaceAll("\\\"","\\\\\"");
		return newJson;
	}
	
}
