There could be several reasons for the error encountered when using the substr function.<\/p>\n

    \n
  1. Incorrect parameters were used: the substr function requires two parameters, the first one being the starting position and the second one being the length to be extracted. If the parameters passed do not meet the requirements, an error will occur. Make sure the parameters passed are valid integer values and that the starting position is not greater than the length of the string.<\/li>\n
  2. The unsupported data type was used: the substr function can only operate on data of the string type. If data of other types are passed, an error will occur. Make sure the parameter being passed is of the string type.<\/li>\n
  3. The use of unsupported function: The substr function is a built-in function in JavaScript, which may not be available in other programming languages or have a different usage. Using the substr function in other programming languages may result in errors. Make sure to use the substr function in the correct programming language environment.<\/li>\n<\/ol>\n

    The solution to these problems is as follows:<\/p>\n

      \n
    1. Check if the parameters are valid: Ensure that the passed parameter is a valid integer value, and that the starting position is not greater than the length of the string.<\/li>\n
    2. Check parameter type: Make sure the parameter being passed is a string type of data.<\/li>\n
    3. Make sure to use the correct function: ensure that you are using the substr function in the correct programming language environment, or look for the corresponding function for extracting strings in the programming language and use the correct parameters to call that function.<\/li>\n<\/ol>\n

      Here is an example of using the substr function in JavaScript:<\/p>\n

      var str = \"Hello, World!\";\r\nvar substr = str.substr(7, 5);\r\nconsole.log(substr);  \/\/ \u8f93\u51fa \"World\"\r\n<\/code><\/pre>\n
