lastIndexOf() 方法可返回一个指定的字符串值最后出现的位置,在一个字符串中的指定位置从后向前搜索。 stringObject.indexOf(searchvalue,fromindex) 该方法将从头到尾地检索字符串 stringObject,看它是否含有子串 searchvalue。开始检索的位置在字符串的 fromindex 处或字符串的开头(没 有指定 fromindex 时)。如果找...
js报错TypeError: Cannot find function match in object 写js脚本时,从上面输出的数据,给下面的模块引用;console.log() 显示传入的值为{5.0, 6.0},但下面的模块会报错 TypeError: Cannot find function match in object 。但定义一个变量,值同为 {5.0, 6.0} 就不会报错。百度无果,遂翻看类似的文章。突然想到...
