onclick="joint('${option.id}', '${option.essay}')" ${option.essay}为Boolean 抛出异常该怎样解决

如果${option.essay}是一个Boolean类型的变量,则可以使用条件语句来解决。例如,你可以这样写代码:
```
onclick="joint('${option.id}', ${option.essay ? 'true' : 'false'})"
```
这里使用了三元运算符,根据${option.essay}的值,返回'true'或'false'字符串。当${option.essay}为true时,返回'true'字符串,当${option.essay}为false时,返回'false'字符串。
这种方法可以确保onclick事件处理程序接收到的参数是字符串类型,而不是Boolean类型,从而避免了类型错误异常。
另外,如果${option.essay}不是Boolean类型,而是其他类型的变量,那么你可以根据实际情况进行相应的处理,比如将它转换为字符串类型,或者使用默认值等。
