这个错误通常意味着你正在尝试读取一个空值的属性。在引用中,报错信息是"TypeError:无法读取null的属性(读取’indexOf’)",这表明你正在尝试在一个null值上使用indexOf方法。在引用和中也有类似的情况。在这些引用中,报错信息都是"TypeError: Cannot read properties of null",这意味着你正在尝试读取一个空值的属性,但具体是什么属性没有被提及。
要解决这个错误,你需要确保你在使用之前对变量进行了正确的初始化,避免将null分配给变量。你还可以使用条件语句来检查变量是否为空,然后再执行相应的操作,以避免错误的发生。如果你不确定哪个属性为空,可以使用调试工具来跟踪代码并找到产生错误的具体位置。<em>1</em><em>2</em><em>3</em>
